Technology SaaS & Cloud AI & Agentic AI

“When the Business Needs One Clear Answer”Sheila advises businesses when technology, customer pressure, data, money and commercial risk collide in the same decision.A product is ready to launch. A major customer wants the contract signed. An AI system can now act inside customer environments. Data needs to move across borders. A distributor wants exclusivity. Capital is about to move. Indonesia is the next market.The business still needs one clear answer:“Can we move, and what could hurt us if we do?”That is where Sheila works best.She leads Sheila Thomas Law Office’s technology, AI, data privacy and commercial transactions practice and acts as external general counsel to an Asia-headquartered SaaS principal operating across multiple international markets. Her work spans SaaS and cloud, AI and Agentic AI, cross-border data, enterprise customer negotiations, distribution, strategic funding and Indonesia market entry. What distinguishes her approach is not simply breadth.It is seeing how one decision changes the others.A product decision changes the contract.A customer demand changes the economics.A privacy position can determine whether the deal signs.An AI capability changes responsibility.A distribution model changes control.A funding structure changes the downside.Sheila’s role is to see those connections early enough that the business still has room to shape the outcome.Technology, SaaS & CloudSheila advises technology businesses on the contracts and legal structures behind SaaS, cloud, digital platforms and enterprise technology.Her focus is commercial:Can the product be sold? Can the customer sign? Can the service be delivered without impossible promises? Can data move? Can the model scale?Her experience includes building connected contracts, privacy documents and reseller structures for multi-cloud observability SaaS businesses operating across international markets and expanding into autonomous and semi-autonomous Agentic AI. The objective is not simply legal compliance.It is to make the technology sellable, deployable and defensible.AI & Agentic AISheila’s Agentic AI work focuses on systems that can go beyond generating output to accessing systems, analysing incidents, making decisions, interacting with tools and carrying out approved actions. Once AI can act, the legal questions change.What may the AI do?What still requires human approval?What happens when third-party models or infrastructure are involved?Who carries responsibility when the system acts?Where should the provider’s responsibility stop?Sheila works on turning those questions into customer-facing AI terms, authority limits, approval points, data rules and responsibility boundaries.For the business, the goal is simple:greater capability should not automatically mean unlimited responsibility.Major Customer DealsSheila has handled high-value cross-border contracts with enterprise customers and resellers, including deals involving multi-million-dollar commercial value and substantial annual consumption commitments. Many counterparties were commercially powerful and, in some cases, heavily regulated.She focuses on the terms that determine whether valuable revenue remains good business after signing:payment, service performance, data use, AI actions, liability, customer remedies and termination. The point is not merely to get the customer.It is to win the customer without allowing bargaining power to turn revenue into open-ended exposure.Indonesia Market EntrySheila has handled Indonesian market-entry work for a first-mover multi-cloud observability platform entering a category dominated by major global technology providers. The work addressed what the business needed to sell, contract, handle data, appoint partners and scale in Indonesia, while preparing for growing AI and Agentic AI capabilities.The firm’s broader technology experience also includes helping bring palm-payment technology, among the first of its kind in Asia outside China, into Indonesia where no established local testing or certification route existed. The principle is straightforward:find the issue that could stop the rollout before substantial time and money have already been committed.Strategic FundingSheila also advises on strategic funding and commercial loan arrangements, particularly where getting the money back matters as much as putting it in.She has structured multiple significant funding arrangements for medical technology businesses around repayment, agreed returns, security, default and downside protection. Across those arrangements, principal and agreed returns were repaid. Her approach is simple:the time to test repayment protection is before the money moves, not after repayment becomes the problem.Built for the Bad DaySheila brings nearly two decades of professional experience advising and representing Indonesian, foreign and multinational businesses. Earlier in her career, she handled high-value civil and commercial matters involving product liability, principal–distributor relationships, restructuring and insolvency, competition matters, international arbitration, enforcement and situations where financial exposure, business continuity and reputation were at stake. She later co-founded an Indonesian law firm and led its Litigation Division. Today, that experience is used before the dispute starts.She anticipates:What if the customer stops paying?What if the distributor underperforms?What if the technology fails?What if responsibility is challenged?What if the relationship needs to end?Which clause matters when the parties are no longer friendly?The purpose is not to prepare for litigation.It is to make the commercial position harder to break in the first place.External General CounselSheila acts as external general counsel to an Asia-headquartered SaaS principal operating across multiple international markets, supporting technology contracts, Agentic AI, data privacy, reseller arrangements and broader commercial matters. That ongoing role means her advice is shaped by the decisions businesses actually make over time:selling, negotiating, launching, changing products, managing customers and expanding into new markets.RecognitionFinalist -

Public Notary & Land Conveyancer (Notaris & PPAT) Foreign Investment & PMA Corporate Transactions

“When the Deal Is Agreed, the Documents Still Have to Make It Work”Jennifer is the firm’s Notary Partner and a Public Notary and Land Conveyancer in Jakarta, Indonesia.When the Transaction Also Needs a NotarySome matters do not end when the contract is signed.A foreign investment may still need a PMA company, corporate deed, shareholder or management change, OSS update or other filing. A property transaction may still need the right land documentation and registration. A corporate restructuring may still need the agreed commercial position reflected correctly in the company’s formal records.Jennifer handles that implementation as the firm’s Notary Partner.This is particularly useful where the legal advice and the notarial work need to stay aligned. The commercial structure agreed with the client can be carried through into the deeds, corporate records, approvals and filings required in Indonesia, rather than being treated as a separate exercise.For the client, that means a matter can move more naturally from:advice → transaction documents → notarial deed → corporate or land implementationwith the same commercial objective kept in view throughout.Jennifer’s role is straightforward:when the transaction needs a Notaris or PPAT to make the agreed structure effective in Indonesia, she takes it through that stage.Foreign Investment & PMAWhere a client is establishing or changing an Indonesian foreign-owned company, Jennifer handles the notarial and corporate implementation of PMA structures, company establishments, investments, shareholder changes, management changes and other corporate actions. Her work also covers business-sector eligibility, OSS and licensing requirements, investment restrictions and the corporate documents needed to put the agreed structure into effect. For the client, the question is not merely:“Can we establish a company in Indonesia?”It is:“Can this company actually conduct the business we intend to conduct once it is established?”Corporate Transactions & ChangesJennifer prepares and formalises deeds for investments, corporate transactions, company establishments and amendments, shareholder changes, management changes and other corporate actions. The focus is on making sure the agreed deal can be carried through into the notarial deed, corporate records, government filings and licensing position.For the client: signing is not the end of the transaction. The corporate records still need to reflect what was agreed.OSS, Licensing & Corporate RecordsJennifer also handles the notarial and corporate implementation of matters involving OSS and business licensing. This becomes important when a company changes its business activities, shareholders, management, capital or corporate structure.A mismatch between the deed, corporate records and licensing position can surface later during a banking process, tender, financing, investment, licence update or another transaction.The aim is to identify and correct that mismatch before it becomes the reason the business cannot proceed.Land & PropertyAs a Land Conveyancer (PPAT), Jennifer handles land and property transactions and the related documentation and registration. For corporate and foreign-investor matters, the practical question is:Can the proposed ownership or usage structure actually be implemented under the available Indonesian land rights?That question matters before significant money is committed, not afterwards.AppointmentPublic Notary (Notaris) - Minister of Law of the Republic of IndonesiaLand Conveyancer (PPAT)- Ministry of Agrarian Affairs and Spatial Planning / National Land AgencyContactJennifer works with clients through Sheila Thomas Law Office in matters requiring notarial, corporate or land implementation in Indonesia.

Technology SaaS & Cloud Data Privacy & Cross-Border Data

“From Legal Answer to Business Execution”Jane helps businesses turn a commercial decision into something they can actually sign, launch, fund or implement.She works across technology and SaaS contracts, data privacy, Indonesia market entry, commercial transactions and strategic funding, particularly where several pieces need to work together before the business can move.Her strength is execution.A product may need local approvals, privacy work and commercial documents before it can launch. A major SaaS customer may want extensive data, service and liability commitments before signing. A funding deal may look straightforward until the business asks what happens if repayment does not go to plan.Jane works through those moving parts so the contract, business structure, corporate documents, data position and practical implementation point in the same direction. For clients, the question she keeps coming back to is:What still needs to happen before the business can move?Selected ExperienceFirst-Mover Palm-Payment Technology in IndonesiaWorked on the Indonesian deployment of palm-payment technology, among the first of its kind in Asia outside China, from early regulatory and testing work through preparation for market rollout. There was no ready-made local certification path.Jane worked through frequency laboratory testing, telecommunications certification, distribution licensing, exclusivity arrangements, biometric-data and privacy issues, and the commercial documentation needed for deployment. The initial rollout was structured as a trial phase, with broader deployment planned if the trial proved successful. For the business: an unfamiliar regulatory route did not have to stop the technology. The work identified the legal, technical and commercial steps needed to move it toward market.High-Value Cross-Border Enterprise SaaS DealSupported an Asia-headquartered SaaS principal in closing a significant enterprise consumption commitment with a listed, regulated customer, from commercial discussions through negotiation to signed commitment. The customer’s size and regulatory environment brought demanding data, operational, service and contract requirements.Jane worked through the commercial model, consumption and payment terms, service commitments, data obligations, liability and other protections needed to get the deal signed without allowing the customer’s bargaining power to shift more risk onto the provider than the deal justified. For the business: a valuable enterprise customer could be secured without sacrificing the commercial position simply to win the deal.Strategic Funding & Repayment ProtectionJane also works on strategic loans and business funding, with particular attention to what happens after the money has been advanced.Her focus includes repayment, security, default protection and whether the lender still has a workable position if the original business plan fails. The commercial principle is straightforward:getting the money back matters just as much as getting the funding out.Data Privacy That Follows the ProductJane advises on operational privacy matters involving facial biometrics, voice data and e-KYC, where the documents need to reflect how the technology actually collects, uses and moves data. She looks at who collects the data, who controls each step, where it moves and which party should carry responsibility.For technology providers, that matters because an inaccurate privacy or contract position can leave one party carrying responsibility for systems, processing or incidents it does not actually control.Legal, Notarial & Tax PerspectiveJane’s background spans law, notarial studies and tax. That combination is useful where signing the contract is only part of the job.She can look at the commercial agreement alongside corporate documents, implementation steps, money flows and the local structure needed to put the transaction into effect in Indonesia.For the client: less distance between what is agreed on paper and what the business actually has to do next.QualificationsCertified GDPR PractitionerCertified Business Contract DrafterCertified Tax Consultant - Brevet A & BProfessional MembershipsAPPDI - Indonesian Data Protection Practitioner AssociationAPKHBI - Indonesian Professional Consultant of Business and Law

Technology SaaS & Digital Platforms Commercial Contracts & Risk

Steven works on technology and commercial deals where the contract may look acceptable at signing but become expensive when something goes wrong.His strength is pressure-testing the position before the business commits.He focuses on the terms that can decide whether a valuable deal remains good business after signing: liability, indemnities, data use, intellectual property, service commitments, customer remedies and termination rights. Steven reads the contract from the other side of the table:If the customer makes a claim later, where will it attack? If performance slips, which promise becomes dangerous? If third-party technology fails, who carries the consequence? If the relationship stops working, can the business actually get out?That perspective is particularly useful in enterprise SaaS, AI and digital-platform deals, where a large customer’s bargaining power or broad service expectations can create exposure far beyond the value of the contract itself.His objective is not to remove every risk.It is to make sure the business knows which risks it is accepting, which risks should stay with the other party, and which words could become very expensive later.Selected ExperienceEnterprise Terms for Autonomous Agentic AIWorked on customer-facing terms for an enterprise SaaS product introducing autonomous Agentic AI capable of accessing systems, making decisions and carrying out actions within customer environments. Steven focused on the commercial pressure points created when increasingly capable AI is sold to enterprise customers:could a service commitment become a guarantee; could the provider become responsible for behaviour dependent on third-party technology; could customer remedies become disproportionate to the value of the service; could the provider carry responsibility for decisions or environments outside its control; and could termination rights make the commercial relationship unsafe? He pressure-tested the terms with one question:If something goes wrong after deployment, which clause hurts the provider first? For the business: advanced AI capability could be offered to enterprise customers without allowing the product’s sophistication to become open-ended contractual exposure.High-Stakes Cross-Border SaaS NegotiationSupported an Asia-headquartered SaaS principal in negotiating a high-value enterprise contract with a heavily regulated corporate customer, where the customer’s size, bargaining power and compliance demands put substantial pressure on the provider’s position. Steven focused on the provisions most likely to become expensive after signing: liability, customer remedies, service commitments, data use, third-party technology and termination.He identified where the customer’s proposed wording could make the provider responsible for risks it did not control or expose it to losses far beyond the economics of the deal. For the business: the goal was not simply to win a major customer. It was to win the customer without turning valuable revenue into a long-term source of uncontrolled risk.Contracts Built for the Bad DayContracts are easiest to agree when both sides expect everything to work.The provisions that matter most often reveal themselves later, when performance slips, payment is disputed, technology fails, a customer seeks a remedy or one party wants out.Steven works on those points before signing, while the business still has leverage to change them.His work is particularly relevant when:a major customer sends its own “standard” contract; liability is far larger than the value of the deal; service levels or warranties may promise more than the product can reliably deliver; third-party technology or customer-controlled systems affect performance; remedies could destroy the economics of the transaction; or termination rights could trap the business in a relationship that no longer works. The purpose is simple:find the weakness while it can still be fixed, not after it becomes a claim.Data Privacy & ResponsibilitySteven also advises on data privacy and personal data protection, particularly where privacy obligations sit inside broader SaaS, AI and technology contracts.He looks beyond whether a privacy requirement exists to ask who actually controls the data, which systems are involved, what each party is responsible for and whether the contract pushes responsibility onto a business for something another party controls.For technology providers, that distinction can determine who carries the cost when a data issue becomes a customer or regulatory problem.Why His Advocacy Background MattersSteven’s instinct for testing the other side’s argument was developed through international commercial arbitration advocacy.At the 20th Vis East International Commercial Arbitration Moot in Hong Kong, his team reached the Semi-Finals, finishing in the top four out of 111 international teams and as the highest-ranking Indonesian team. He also received an Honourable Mention for the David Hunter Award for Best Claimant Memorandum. The value to his transactional work today is straightforward:he reads an agreement not only for what the parties intend it to mean, but for how the wording could be used against the client if the relationship is later tested.QualificationsCertified GDPR PractitionerCertified Business Contract DrafterProfessional MembershipsAPPDI - Indonesian Data Protection Practitioner AssociationAPKHBI - Indonesian Professional Consultant of Business and Law

Enterprise AI & Agentic AI Technology Transactions Data Privacy & Cross-Border Data

“When the AI Can Act, the Contract Has to Catch Up”Adhi works with businesses deploying AI and Agentic AI that can do more than generate answers.When a system can access customer environments, make decisions or carry out actions, the legal question changes. It is no longer only what does the software do? It becomes:What is the AI allowed to do? When must a human approve it? What data can it use? Who carries responsibility when it acts? And where should the provider’s responsibility stop?That is where Adhi is particularly strong.His technical exposure to AI and software allows him to look beyond the wording of the contract and understand how the product actually behaves, what it can access, what it can decide, what it can execute and where things could go wrong.He translates that behaviour into customer terms, approval points, data-use rules and limits on responsibility that businesses can use when selling and deploying advanced technology.For technology companies, that matters because a contract that does not match the product can create a problem at exactly the wrong time: during enterprise procurement, customer due diligence, deployment or after the system has already acted.Selected ExperienceCustomer-Facing Terms for Autonomous Agentic AIWorked on the AI Terms of Service for an enterprise SaaS product using autonomous Agentic AI, where the system could go beyond generating output to accessing systems, making decisions and carrying out actions.Adhi worked through the questions that ordinary software terms do not fully answer:what the AI was permitted to do;when human approval remained necessary;how customer data could be used;how responsibility should be divided where third-party models or infrastructure were involved; andwhere the SaaS provider’s responsibility needed to stop.The objective was to ensure the customer-facing terms followed the real behaviour of the system, so the product could be sold and deployed without creating promises that did not match the technology.For the business: advanced AI capability could be brought to enterprise customers with clearer limits around control, responsibility and risk.AI-Powered e-KYC, Biometrics & Identity VerificationWorked on the privacy position and Record of Processing Activities for an AI-powered e-KYC product used in financial services, involving ID-document recognition, facial verification, liveness checks, anti-forgery controls and AI-based defenses against deepfakes and identity fraud.Adhi mapped what data was collected, how it was checked, where it moved, which party controlled each step and who should carry responsibility if something went wrong.A key part of the work was making sure the technology provider was not treated as responsible for processing, security failures or data incidents caused by another party’s systems, instructions or control.For the business: the legal position followed the real product and data flow, reducing the risk that the provider would carry responsibility for something it did not cause or control.Why His Technical Background MattersBefore joining private practice, Adhi worked with Sheffield Digital Justice on generative AI and the development of an AI-powered legal platform.His work examined accuracy, bias, hallucination, transparency and digital accessibility - practical questions about what an AI system can do and what people can safely rely on it to do.That experience is directly relevant to enterprise AI work today.It means Adhi approaches an AI contract by asking not only “what does the clause say?”, but also:“Does this actually match the technology?”His work in this area also led to a speaking role at the Sheffield & District Law Society Legal Tech and AI Conference.Adhi holds an LL.M. in Commercial and Corporate Law from the University of Sheffield, where his academic work included AI, UK contract law and the EU AI Act. His international transactional exposure also includes experience with White & Case in London.QualificationsCertified GDPR PractitionerCertified Business Contract DrafterProfessional MembershipsAPPDI - Indonesian Data Protection Practitioner AssociationAPKHBI - Indonesian Professional Consultant of Business and LawPERADI - Indonesian Bar AssociationSheffield AlumniRecognition1st Winner - World Tourism Day 2021The International Institute of Tourism & BusinessRecognised for developing a legal and commercial approach to sustainable tourism during COVID-19 that brought together health, environmental and business requirements into a practical model for businesses and communities.
