How we work with founders
From idea to live, and with you as you grow.
We stay your technical partner until you find the ideal in-house CTO co-founder, or build a senior team of your own.
Build
Turn an idea into a live product, plus AI agents and work automations.
Grow
Extend and enhance products already in the market.
Scale
The architecture and reliability a growing user base demands.
Why most ideas stall
The hardest part isn't the idea. It's finding a team that ships.
- Hire a CTO
- Months of searching, equity given before a line of code, and the wrong hire can set you back a year.
- Freelancers
- Affordable until they go quiet mid-build, leaving behind code nobody else can maintain.
- Large agencies
- Senior names in the pitch, junior hands on the keyboard, and a polished demo that never reaches production.
- No-code tools
- Fast to a point, then a wall the moment you need real logic, payments, or scale.
KUMO works like your in-house engineering team. A senior product and AI partner that takes your product from idea to live, and stays as you grow.
Working with KUMO
A partner for the whole journey, not a one-off vendor.
The way we work is built around how founders actually grow, from the first build through every stage after.
Fixed scope, fast
Milestone-based engagements, typically 2 to 3 months to a launched product. You always know what you are paying for and when it ships.
Frictionless handover
When you raise or bring on an in-house dev team, we hand over a documented, maintainable codebase. No lock-in, no rewrite, no friction.
Support until stable
We do not disappear at launch. Continuous support and maintenance until your product is stable in the hands of real users.
On call, anytime
Resume development whenever you want to take the product to its next stage. Our engineering expertise is on call at any point you need it.
You own everything
Full IP and a codebase you own, built to extend, so your team or your next hire can keep building on it.
Services
Production software and AI, designed end to end.

CampaignHQ
We build and operate CampaignHQ, an in-house SaaS used by many startups for email and WhatsApp marketing. Running our own product keeps us honest about shipping and operating software in production.
