Who this is for — and who it isn't.
A good fit
- Software or SaaS companies looking for a senior team to build web, mobile, or AI features
- Founders, CTOs, and Product Leaders who want software shipped every 2 weeks
- Funded startups and pre-launch founders building a high-impact v1 product
- Companies needing multi-tenant SaaS architecture, complex APIs, or LLM integrations
- Teams looking for 100% code ownership, direct communication, and zero middleman fluff
Not a fit
- Looking for a cheap template website or the absolute lowest bidder
- "I have an idea but zero budget — let's do equity only"
- Enterprise procurement requiring 12 months of RFP paperwork before starting
- Small local businesses seeking simple basic office spreadsheets
Questions founders & CTOs ask.
Yes, 100%. We work directly inside your GitHub/GitLab repositories and your cloud infrastructure. Every pull request and line of code is yours, merged as we build. Zero lock-in.
Every 2-week cycle begins with a clear scope alignment and ends with a live working demo. You see continuous progress and can redirect features early.
