Recent work
Results our clients can put in a board deck
Real projects and real metrics: decision time cut from days to minutes, conversion lifted double digits, platforms scaled past 50,000 shipments a month.
How we work
A process with no surprises, disclosed up front
From first call to launch, you always know what happens next, what it costs, and what you'll have at the end of the week.
- 01
Scope call
45 minutes · free
A working session, not a sales pitch. We dig into what you're building, why now, and what success looks like in numbers.
- 02
Fixed proposal
Within 5 business days
A scoped plan with a fixed price, a real timeline, and the trade-offs stated plainly, so the decision is easy to make and defend.
- 03
Weekly sprints & demos
The build phase, in weeks not quarters
Working software every week. You watch the product grow in a live demo each Friday and steer priorities while changes are still cheap.
- 04
Launch & support
Ongoing, on your terms
We launch together, watch the metrics, and stay available. Most clients keep us on retainer; all clients keep everything we built.
Why Corintix
Built like an engineering team, priced like a partner
The four commitments every client gets in writing, not as marketing but as working agreements.
Weeks, not quarters
Fixed scope, weekly demos, and a launch date we protect. Most MVPs ship in 8–12 weeks.
Senior team, no relay
You work directly with the engineers and designers building your product. The same people, start to finish.
You own everything
Code, IP, infrastructure, and docs transfer to you at every milestone. Zero lock-in by design.
Quality that's measured
Performance budgets, accessibility checks, and test coverage enforced in CI, not promised in slides.
Client outcomes
What working with us actually feels like
From the people who bet their roadmap on us: engineering leaders, founders, and product owners. Hover, or press and hold, to pause.
“They scoped honestly, cut features we didn't need, and shipped two weeks early. The weekly demos meant zero surprises, and our board saw working software every month.”
Daniel R.CTO, logistics SaaS startup “The first development partner that treated performance and accessibility as requirements instead of upsells. Our conversion rate is up double digits and the codebase is one our own hires compliment.”
Priya S.VP Engineering, e-commerce brand “We'd been burned by an AI vendor that demoed well and failed in production. Corintix built the evaluation suite before the feature, and it's been reliable for a year.”
Marcus T.Head of Product, B2B software company “Our members hated the old app and told us weekly. Four months after the rebuild we were at 4.7 stars, and the board still brings up the pen test report: zero critical findings.”
Susan K.COO, regional credit union “They told us in week one that half our wishlist wasn't worth building. That honesty saved us six figures, and the half we did build paid for itself in a quarter.”
James O.Founder, insurance brokerage “I expected a vendor. What we got was a team that argued with us about the right things, shipped every Friday, and left us with documentation our new hires actually read.”
Elena V.Managing Partner, corporate law firm “The donation flow rebuild paid for itself before the campaign even ended. Forty-four percent more completed gifts is not a rounding error for a nonprofit our size.”
Grace A.Development Director, international nonprofit “Every agency promises senior people. Corintix is the only one where the people on the sales call were the people writing the code, all the way to launch.”
Tom H.CEO, professional training company
