The firm that writes your software owns it, unless your contract says otherwise.
That is the starting point under US copyright law for software built by an outside firm, and the Copyright Office’s own guidance explains why. It is easy to miss, because nothing in a pitch, a proposal, or an invoice ever brings it up.
Ownership is one of ten things worth checking before you hire a digital platform engineering company, and it shows why this decision is hard. The things that matter most rarely come up in the sales conversation. A pitch will tell you the firm is modern, scalable, and secure, which describes every firm, so the checks in this guide ask for evidence instead of adjectives.
One clarification first, because the term trips people up. In engineering circles, platform engineering usually means building the internal tools that help developers ship faster, which we covered in do you actually need an internal developer platform.
This article uses the agency meaning of the phrase: a firm that designs, builds, modernizes, and often runs a digital platform for your business, such as a SaaS product, a customer portal, a marketplace, or a commerce system. That second meaning has no official definition, which is the first reason to ask any firm what exactly it means by it.
Most of what separates a good partner from a poor one shows up in the answers to ten questions. The table puts them in one place, with what a good answer sounds like and what should make you slow down. The sections after it go deeper on the ones that cause the most expensive mistakes.

What To Ask | A Good Partner Sounds Like |
A Red Flag |
| 1. Relevant experience | “Show me two platforms like mine, and who built them.” | Specific examples at similar scale and in a similar industry, with a client you can call. | Only logos and screenshots, or experience that is close to your situation but not quite. |
| 2. The actual team | “Who will work on this, and where are they?” | Named people, a clear seniority mix, and a plan for what happens if one of them leaves. | Senior people on the pitch, juniors in the delivery, and no names until after you sign. |
| 3. Planning before building | “What happens before any code is written?” | A paid discovery or architecture step that ends in a written plan and a ranked list of risks. | A fixed price quoted from a one-hour call. |
| 4. Delivery record | “How often do you ship, and how do you measure it?” | Release frequency, lead time, and failure rates they can show from a recent project. | “We are agile,” with no numbers behind it. |
| 5. Security practices | “Which secure development practices do you follow, and who checks them?” | A named framework, an independent report or certificate, and plain answers about who can see your data. | Security described as a feature of the finished product rather than of how they work. |
| 6. Industry compliance | “Have you worked under our rules before?” | Direct experience with rules like HIPAA or PCI, and willingness to sign the agreements they require. | “We can learn it as we go.” |
| 7. Ownership and exit | “Who owns the code, and how do we leave if we need to?” | Written assignment of intellectual property to you, repository access from day one, documentation, and a handover plan. | Code that lives only in their systems, or ownership language that is vague. |
| 8. Pricing and change | “How are changes priced, and what is not included?” | An itemized quote, a clear process for scope changes, and hosting and maintenance priced separately. | One lump sum with no detail, or a very low bid that leaves out whole categories of work. |
| 9. Communication | “Who is my single contact, and when are they online?” | One accountable lead, agreed overlap hours with your team, and a regular demo rhythm. | Several contacts, none accountable, and updates only when you ask. |
| 10. References | “Can I speak to a client whose project has a problem?” | Calm, specific answers about a past problem and how it was handled. | Only hand-picked happy clients, or no references at all. |
Checks three and four are the easiest to skip, because they sound like process rather than substance.
The pitch will be delivered by your best salesperson and perhaps a principal engineer. The work will be done by whoever is free. That is not a scandal. It is how services firms operate. What matters is how big the gap is and whether you can see it coming.
Ask for the names and the seniority mix of the team, how long they have been with the firm, and whether any of the work goes to subcontractors. Then ask the question that gets honest answers: if one of those people leaves in month three, what happens?
Also notice what kind of arrangement you are buying. A team that takes responsibility for the outcome is a different thing from engineers who work to your instructions, and the risks and costs differ. We laid out the difference in staff augmentation versus outsourcing: who is actually accountable.
We opened with this one because buyers skip it more than any other. In the US, the person who writes a piece of software is generally its legal author, and so owns the copyright, unless something changes that. If the author is your employee and wrote it as part of their job, the code counts as a work made for hire and your company owns it. An outside firm is not your employee.
The Copyright Office’s guidance on works made for hire says a commissioned work from an independent contractor qualifies only if it falls into one of nine listed categories and both sides sign a written agreement saying so. Custom software is not an obvious fit for any of the nine. The usual fix is a clause in your contract that assigns the intellectual property to you.
So before you pick a firm, ask to see the intellectual property clause. Make sure the code lives in a repository you own from the first day. Ask that third-party and open-source components are listed with their licenses. And read the handover plan closely, because it describes exactly what you receive if the relationship ends. This is general information and not legal advice, so have your own lawyer read this part of any contract.
Two questions cover most of the ground on security. The first is how the firm protects itself and your data. A current SOC 2 report or ISO 27001 certificate from an independent assessor is the usual evidence. Ask for it and read the scope, since a certificate that covers one office or product does not necessarily cover the team that will work on yours.
The second is how the firm builds software securely.
NIST publishes a framework for this, the Secure Software Development Framework, organized into four groups: preparing the organization, protecting the software, producing well-secured software, and responding to vulnerabilities. NIST notes that buyers can use it as a common vocabulary with suppliers. So you can ask a firm to describe its practices in those terms and see how long the answer takes.
If your platform will touch protected health information, the bar is legal as well as technical. HHS says a covered entity must have a written business associate contract with any vendor that handles that information on its behalf. Ask whether the firm has signed one before, and whether it will sign yours. Other regimes, such as FERPA for student records or PCI for card payments, bring their own questions, and the same rule applies: ask for direct experience, not a promise to learn.
That opening sentence about code ownership is a fair summary of the whole decision. What decides whether a platform project goes well is rarely in the marketing. It sits in contract clauses, named engineers, delivery numbers, and clients who are willing to pick up the phone.
Every check in the table is a way of turning an adjective into something you can look at. “Experienced” becomes two platforms you can ask about. “Secure” becomes a report with a scope you can read. “Agile” becomes release numbers from a recent project. A firm that is good at this work will answer all ten in writing without much fuss, and a firm that cannot is telling you something useful before you have paid it anything.
If we make your shortlist, run the ten checks on us too. We would rather lose a deal at the checklist stage than win one that turns sour in month four.
Or tell us what you are planning and we will say honestly whether we are the right fit.
Legacy Modernization, Platform Strategy
Key Takeaways Modernization is a set of decisions, not a rewrite. For each system you choose one of five moves: keep, wrap, move, rebuild in slices, or retire. Start with a business reason you can write in one sentence, then map what you have before you touch any code. Change small slices while old and […]
Digital Transformation, Platform Strategy
Picture the same Tuesday morning, a few months from now. Someone closes a deal in the CRM. The billing record updates itself in the background. Nobody opens a second tab. Nobody retypes a single detail. That is not a fantasy. It is what actually happens once this problem gets fixed, and it is a smaller […]
DevOps, Platform Strategy
Gartner says 80% of large software engineering organizations will have a dedicated platform team by the end of 2026. That stat is everywhere right now. It’s also convinced a wave of 15-person startups that they need an internal developer platform immediately. Most of them are wrong. Here’s why, and how to tell which side of […]
