Software built by a product founder, not a vendor.
You work directly with a former CTO who builds and runs real SaaS products. That means owner-level decisions on architecture, MVPs, fractional CTO leadership, AI cost, and the internal automations and MCPs that make your business run. We build like it is ours, because we do exactly that for ourselves.

Why this beats hiring an agency
Run by a product founder
We build and run our own SaaS products. You get owner-level decisions on architecture and tradeoffs, not a vendor following a spec.
AI-native, with AI costs kept low
We build with AI and design for low running cost, so your AI features stay fast and useful without a runaway bill.
We design the system, not just the app
Architecture, internal workflows, and the MCPs and automations that make your business actually run, not just a screen.
Senior and founder-led, no staff-aug
A former CTO and senior engineers do the work. We do not rent you junior hands by the hour or hand off to a B-team.
How we work
A clear path from first call to a system running in production, with no surprises on scope or cost.
Scope and estimate
A no-cost call to map the problem. You leave with a plan and a fixed estimate, whether or not we work together.
Design and plan
We shape the solution, the AI layer, and the architecture, then agree milestones and a timeline you can hold us to.
Build and ship
Senior engineers build in short cycles with working demos. You see progress every week, not at the end.
Scale and support
We harden, monitor, and extend the system as you grow, on a simple monthly retainer.
Get a free 10-minute teardown
Send us your product, site, or the workflow you want to automate. A former CTO records a short Loom with the highest-impact things we would do and where AI actually helps. No call required, no obligation.
Teams we have shipped for
Trusted on Upwork and beyond
They shipped what three previous teams could not, and they did it on time. The senior involvement was obvious from day one.
Rare combination of deep engineering and real product sense. They told us what not to build, which saved us months.
Reliable, clear communication, and the work held up under heavy load. We kept them on a retainer afterward.
I started Seven Hills to do the work I am proudest of, directly with the people who depend on it. As a CTO and co-founder I led an 18-engineer team and personally shipped the products behind these case studies, from a Fortune 100 shipping system to a SaaS product we built and sold. You work with that experience, not a sales layer on top of it.
