Product studio, founder-led

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.

From a single workflow to a full product

One senior team across AI automation, web, mobile, SaaS, and e-commerce. We build it, ship it, and keep it running.

Custom Web Applications

Dashboards, internal tools, and customer platforms built on a modern React and full-stack foundation.

Mobile Apps

Cross-platform iOS and Android apps with React Native and Flutter, shipped to both stores.

SaaS Product Development

Idea to MVP to scale. Product strategy, UX, and the engineering to back it.

E-commerce Engineering

Shopify, Magento, and WooCommerce builds, large catalog syncs, and integrations across major carts.

Cloud and DevOps

AWS and Kubernetes systems built for autoscaling, reliability, and cost control.

Internal Workflows and MCPs

The automations, internal tools, and MCP integrations that let your team and your AI act inside your real systems.

Why Seven Hills

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

How we work

A clear path from first call to a system running in production, with no surprises on scope or cost.

01

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.

02

Design and plan

We shape the solution, the AI layer, and the architecture, then agree milestones and a timeline you can hold us to.

03

Build and ship

Senior engineers build in short cycles with working demos. You see progress every week, not at the end.

04

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.

Client words

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.

Founder, SaaS companyUpwork review
★★★★★

Rare combination of deep engineering and real product sense. They told us what not to build, which saved us months.

Head of Product, e-commerce brandUpwork review
★★★★★

Reliable, clear communication, and the work held up under heavy load. We kept them on a retainer afterward.

Operations lead, logisticsUpwork review
SH
Founder-led
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.
