Buying
Choosing a product-engineering partner
A strong partner shows systems you can inspect, starts with thorough discovery, and can explain how the work stays healthy for the people who rely on it.
Proof you can inspect
Prefer named work you can inspect: systems still in use, described in plain language. Ask what still runs under load and how the team talks about it.
If the portfolio cannot point at a system people still use, treat it as early-stage concept work.
How they start and stay
Look for a time-boxed discovery pass, a first slice worth shipping, and a clear story about operate and care when you need one.
Ask who replies after launch and how change is priced. Competence shows up in the practical answers.
Contracting basics
When you contract a private limited company, confirm the legal name, company number, and who signs. Company facts live on About and legal pages; delivery evidence lives in the work itself.
