Production-grade
software, at AI speed.
By senior engineers.
Mantixx is an AI-native development agency for founders and operators who need a real product, not a prototype. AI accelerates the work. Senior engineers own every line that ships.
AI handles the volume.
Senior engineers handle the call.
AI accelerates. Seniors decide.
Code generation, test scaffolding, intelligent QA at every stage. Every commit then passes through senior review. The engineer scoping your product is the engineer shipping it.
Production from day one. Not a prototype.
Tests, CI, monitoring, security and performance budgets baked in from week one. The MVP we hand over is the codebase you scale. There is no throwaway code on a Mantixx project.
Honest scope. Fixed fee. Yours forever.
A real MVP that proves your thesis, not a wishlist. Fixed price for fixed scope, billed in two halves. You own the codebase, infrastructure, accounts and IP. We hand it all over with documentation.
Same rhythm, every project.
You always know where it stands.
