Key Brains brought structure to what felt like an impossible requirement. Their engineers understood the business problem, not just the technical one. We shipped 4 weeks ahead of schedule.
Senior engineers only
No juniors on production code. Minimum 8 years average experience on every team. You talk directly to the engineers building your product — not through an account manager.
Architecture before code
Every engagement begins with a written technical specification. No code is written until the architecture is agreed. Your estimates are accurate because we do the real work upfront.
No surprise invoices — ever
Fixed-price projects run to scope. If we mis-estimate, we absorb the overrun. We have never passed an estimation error cost to a client in our history.
