Domain knowledge that shortens delivery
Twelve sectors where we have already made the domain mistakes. That is the difference between a team learning your business and one that already knows it.
Not seeing your sector? We build for every vertical.
Talk to an engineerChoosing a partner
Why growing companies pick a product engineering team
Large consulting firms are the right call for a multi-year, multi-country transformation programme. For building a specific product they run 3 to 5x the cost and several quarters slower. Here is the honest comparison.
Security in the pipeline
OWASP-aligned review on every merge, dependency and secret scanning in CI, and penetration testing on anything handling money or personal data.
8 to 12 weeks to production
A working MVP in the first quarter, with a demo at the end of every two-week sprint. Not a status report.
You own all of it
Source code, database schemas and documentation transfer to you on final payment. No retained licence, no dependency on us.
Twelve months of support
Bug fixes, security patches and minor changes after launch, then an optional retainer if you want us to keep going.
| What matters | Traditional IT services firm | DEV SEC IT |
|---|---|---|
| Who actually writes the code | A rotating bench of contractors | A named senior pod, start to finish |
| Account layer | Partner, PM and an account manager | One technical lead, reachable from day one |
| Commercial model | Time and materials, bill grows with the project | Fixed price against written milestones |
| Time to first release | Three to six months of discovery | 8 to 12 weeks |
| Security | Assessed at the end, if allowed | Built into the pipeline from commit one |
