Start a Project
Tell us what your business actually does.
Not what you want built — what your business does, how it works, where things break down. The brief writes itself from there.
Engagement Models
Logic Audit
You have a system. Something's wrong with it, or you're not sure what to build next. We map the logic, identify the gaps, and produce a structured spec — whether you build it with us or not.
- Investment
- From $3,500
- Timeframe
- 1–2 weeks
Full Build
Discovery through handover. Logic map, data model, front-end and back-end build, documentation. You leave with ownership of a complete, working system.
- Investment
- Project-scoped
- Timeframe
- 6–16 weeks
Retained
An ongoing technical partner. We continue building as your requirements evolve — without you having to re-brief someone new each time. Technical co-founder energy, without the equity conversation.
- Investment
- From $5,000/mo
- Timeframe
- Rolling
Drop a brief
We reply within one business day. The first call is a discovery session — we map the logic together and tell you what we'd build, with or without us.
