Every engagement follows the same process: scope it honestly, quote an hour range with a hard ceiling, ship in visible weekly increments, and stand behind the code for 6 months after launch. Here's exactly what that looks like.
Every engagement follows the same process: scope it honestly, quote an hour range with a hard ceiling, ship in visible weekly increments, and stand behind the code for 6 months after launch.
A 30-minute call with someone who can actually scope your project — not a sales rep. Bring your idea, your existing codebase, or your backlog. If we're not the right fit, we'll tell you on this call and point you somewhere better.
We map your screens, workflows, and edge cases, then quote an hour range — not a vague "it depends." Already have a codebase? We review it free and tell you honestly whether we can work with it.
You contract directly with our US company. The contract lists milestones, deadlines, and the hour range. The maximum in that range is the most you'll ever pay for the agreed scope — if we go over, the overage is on us.
Work runs in two-week sprints. Your first sprint starts two weeks after signing. You see working software every week — not a big reveal at the end.
Documented, security-reviewed, and SEO-ready. You own every line of code in your own GitHub org.
If anything we delivered breaks, we fix it free. No ticket triage games, no "that's out of scope."
Every week, we walk you through the live product together — not a slide deck, the actual app. You click through it, we take notes.
Every request, bug, and idea lives in one tracker you can see. Statuses mean something: "in progress" means we're on it, "resolved" means it's live in production — often within hours of the fix.
You don't wait for launch to try things. You get a staging environment (with test payment cards where relevant) so you can QA features the same day we ship them.
You talk to the engineers building your product, not an account manager relaying messages. Responses within 48 hours, usually much faster.
Our teams overlap 6am–6pm Pacific, whether your engineers are onshore in the US or nearshore in Turkey. US management on every project.
Most agencies quote low, then bill the difference. We do the opposite.
Every contract states an hour range. If the work runs past the maximum, we finish the agreed scope at no extra cost. You never pay more than the ceiling for what's in the contract.
Fixed-price projects are paid in installments tied to delivery — typically six payments, the first due two weeks after signing and the last after delivery and approval. You're never paying for work you haven't seen.
You contract with our California-based company. Your IP is protected under American contracts from day one.
6 months on every line of delivered code (6–12 months on hourly engagements). If it breaks, we fix it free.
One of our clients spent two years with a larger team trying to ship their MVP. Two of our engineers delivered it in four months.
That's not because we work weekends — it's because senior engineers with AI-assisted workflows, clear milestones, and a client who sees progress every week don't accumulate the misunderstandings that kill projects.
"We worked with another agency and faced surprising costs because of unthought estimations. Working with HorizonLabs enabled us to work without surprises with well set estimations and expectations."
Horizon Labs is three co-founders who trust each other because we've earned it over a decade, not a partnership agreement. Serdar and Sinan have known each other since high school. Saif met Sinan on Reddit in 2018, and they were briefly co-founders before Sinan went through Y Combinator. In 2019, Serdar helped Sinan build Cuboh (YC S19) — the startup Sinan later sold. The engineers who shipped Cuboh never left: they're the same people managing delivery on client projects today. We didn't assemble a team for this agency. We kept one that already worked.
YC alum with multiple exits and a CTO background. Sinan sets the technical bar — and is the reason many of our clients found us, because founders he's worked with keep sending their friends.
Serdar runs every engagement: project management, product management, and team tracking. When you hire us, he's the one accountable for your milestones — the same role he played building Cuboh.
An ex- VC whose been building startups since 2010, Saif covers everything non-technical: contracts, go-to-market strategies, launch support, and product management.
Usually Serdar leading delivery alongside your assigned engineers, and Saif on GTM and business support. That structure isn't for everyone. If you're looking for quick, cheap labor that says yes to everything, we're a bad fit. If you want a technical partner that's been working together for ten years and will tell you when we think your approach is wrong — before you pay for it — we should talk.
You don't pay more. The contract states an hour range, and the maximum is the most you'll ever pay for the agreed scope. New scope you add along the way is quoted separately before we build it.
You do. All work happens in your GitHub org, and your IP is assigned to you under a US contract.
Usually, yes. We review it free first and tell you honestly whether we can work with it under our standard terms, or whether a rebuild makes more sense. Our fixed-price guarantee applies to net-new code we write from scratch.
Management and leadership are in California. Engineers are onshore in the US or nearshore in Turkey, all overlapping US hours (6am–6pm Pacific). You contract with our US company either way.
Any defect in code we delivered, for 6 months after delivery (6–12 months on hourly engagements). If it breaks, we fix it free. It doesn't cover changes to scope or third-party services breaking their own APIs — we'll quote those separately.
Scoping usually takes under a week. Your first sprint starts two weeks after signing.
Yes, deliberately. Senior engineers use AI to cut delivery time without cutting quality — it's why our fixed prices run ~50% below our standard hourly equivalent. Client code only touches AI in secure environments.
Tell us what you're building. We'll come back with an honest scope, an hour range, and a hard ceiling — usually within a week.
