Software engineering,
invisible by contract.
NovaStack builds production software with strictly typed code and relational databases — no visual builders, no missed dates. For agencies, we work under your brand. For founders, we build your product.
FOR AGENCIES

We handle the heavy custom engineering behind the scenes, under your brand. You keep 100% of the credit and the margin.

We do not build marketing websites or do brand design. If that's what you need, our sister company Anchor & Co. Sites — same owners, different craft — builds websites for small businesses. NovaStack is the engineering layer.
Built and shipped
All work →
Most of our portfolio ships under NDA, credited to the agencies we partner with — like Client name under NDA and Client name under NDA. What we can show, we show live.
From scope to launch date
01
Technical fit call
A brief call to evaluate scope, stack and timeline. For agencies, the NDA is signed before your client's project is discussed.
02
Fixed scope, fixed date
Contract defines deliverables, tier pricing and the launch date. Schema and architecture are designed before service code is written.
03
Sprints to handover
Predictable engineering sprints with tested endpoints, then full repository handover with documentation. The code is yours.
The team behind the curtain
Samuel Carvajal Restrepo
Founder, CEO & Lead Developer
Architecture, delivery guarantees and the strictly typed standard every project ships under.
Alejandro Zapata Yepes
Sales Director, Co-Founder
Your deal engineer — aligns our technical output with your margins before any contract is signed.
Juan José Espinosa Álvarez
Marketing Director, Co-Founder
Marketing and media management — the reason you found us, and the reason your launch gets seen.
Your next build, shipped on a date we put in writing.
Fixed pricing from $2,500 per project. NDA before the first line of code. Full code ownership at handover — whether you're an agency or it's your own product.
