How this works

One AI-native engineer.
The output of a team.

The local read

Why react & next.js engineering is hard in New York

NYC founders have a worse hiring problem than the funding headlines suggest. Half your top engineering candidates are weighing your seed offer against a $400K Google package. The dev shops in town are agency-of-record operations billing hourly, or staffing shops shoveling juniors into your team.

We're neither. One named senior engineer owns the build end-to-end. Flat price quoted after a 30-minute call. Eastern Time, same as your General Catalyst partner and your midtown customers. When we finish, the code is in your GitHub and the contract is over. No retainer.

Hiring one senior engineer here is a ~$310K year-one outlay and a 60–90 day search. Our react & next.js engineering engagement starts at $6,000 with a first deploy in 2–4 weeks.

“When we started, there was no website, no technical foundation, just an idea and a clear vision of what I wanted to build. Valery and the Start Matter team took that vision seriously and helped me turn it into a real product from scratch. What I appreciated most was how easy and human the collaboration felt. They listened carefully, explained things in a way I could understand, and genuinely cared about building something that would work long-term, not just "finish a task." I always felt supported and involved in the process. Start Matter handled everything end to end and made the whole journey smooth and stress-free. Today, Sweet and Savory Meals is live, growing, and built on a solid foundation I trust. I’m truly grateful for their work, their patience, and their commitment, and I would happily recommend Start Matter to anyone looking for a reliable and thoughtful development partner.”

“Working with Start Matter has been a fantastic experience. When we brought Start Matter into the Brain.fm project, we were looking for more than just developers — we needed a team that could think with us, help shape the product, and execute at a high level. Start Matter did exactly that and more. From early iterations to complex feature development, the team showed deep technical expertise, strong problem-solving skills, and a clear focus on delivering value. Communication was always open and honest, and they were great about adapting to changes and challenges without missing a beat. What really stood out was their ability to integrate seamlessly with our internal team and match our pace. They consistently delivered high-quality work and made sure we felt supported at every step. I'm very grateful for their professionalism, creativity, and commitment to excellence. I would highly recommend Start Matter to anyone who wants a reliable, skilled, and thoughtful development partner.”

Common questions about react & next.js engineering
in New York

How fast can you start?

Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Pages Router or App Router?

Default to App Router for new builds — server components, streaming, Cache Components, and the routing primitives are where Vercel and the framework are investing. We migrate Pages → App on request.

Can you work with our existing backend?

Yes — REST, GraphQL, gRPC, your homegrown JSON-RPC. We wrap it in a typed client and the frontend doesn't care about the protocol underneath.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
