Fixed price to launch
A scoped MVP at a fixed number, validate the business before betting the runway.
How we work
Product scoping
We cut the idea to the smallest version that proves someone will pay, the core workflow, not the wishlist.
Architecture
Tenancy model, data model, auth, billing and API contract decided up front. The choices that are expensive to change.
Weekly builds
Working software every week from week one. You test the product, not a prototype.
Launch infrastructure
Billing live, onboarding tuned, monitoring and error tracking on, launched like a business, not a demo.
Iterate
Usage data and real feedback drive the roadmap. The next version is informed, not guessed.

Frequently asked questions
How much does it cost to build a SaaS?
A focused MVP starts around $5–8K and ships in 6–10 weeks; full products scale with scope. Fixed quote after scoping: you validate the business before spending the runway.
How long does SaaS development take?
An MVP in 6–10 weeks, a full product in months. Weekly builds mean you're testing real software throughout.
Can you build the billing and multi-tenancy too?
Yes, those are the hard parts we specialize in. Stripe/Polar.sh billing, tenant isolation, roles and onboarding are core to every SaaS we ship.
Do you work with non-technical founders?
Constantly. We translate the business model into the product and handle the technical decisions. You approve the scope and see it built weekly.
What happens after the MVP launches?
Support window included, then iteration driven by real usage, or handover to your team with docs if you're hiring engineers.
