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

One senior engineer plus AI agents now ships mobile app development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Atlanta who need to ship before the next round closes.

Why mobile app development is hard in Atlanta

Atlanta's fintech and B2B SaaS hiring market is tighter than the headlines suggest. 60+ days average to fill a senior role. $250K all-in for the kind of engineer who can wire Plaid, Stripe, and ACH rails without breaking compliance.

We do that work weekly. One named senior engineer, Eastern Time, overlap with your Atlanta team and your East Coast investors. Java + Spring for fintech. Next.js + Postgres for SaaS. EDI integrations for supply-chain. Flat-price quote in 24 hours. Code in your GitHub from commit one.

Hiring one senior engineer here is a ~$250K year-one outlay and a 60–90 day search. Our mobile app development engagement starts at $10,000 with a first deploy in 3–6 weeks to TestFlight.

Throughout the engagement, their team consistently demonstrated exceptional technical expertise, strong strategic insight, and a remarkable attention to detail. What stood out most was their ability to guide us through every phase of the process while remaining flexible, collaborative, and highly responsive to evolving business requirements. Their domain expertise was instrumental in helping us shape the product vision and successfully bring the platform to market. In addition, their pricing model was fair and transparent, and the level of partnership they provided made a meaningful difference in our ability to execute efficiently and stay aligned to our launch objectives.

“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.”

“I had the pleasure of working with Start Matter while building Getquin from the very first idea stage. At the beginning, Getquin was just a concept. Start Matter helped us turn that concept into a real, scalable product. From product discovery and architecture to development and early iterations, the team was deeply involved and consistently proactive. They didn’t just execute tasks, they thought like product partners and helped us make the right technical and strategic decisions early on. What impressed me most was their ability to move fast without sacrificing quality. The foundation they built allowed us to validate the idea quickly, iterate confidently, and ultimately reach a stage where we successfully raised investment. Start Matter played a key role in transforming our idea into an investor-ready product. Their professionalism, technical expertise, and founder-level mindset made a real difference for Getquin's early success. I would strongly recommend Start Matter to founders who are looking to build a product from scratch and need a reliable, experienced team they can truly trust.”

Common questions about mobile app development
in Atlanta

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.

React Native or native (Swift/Kotlin)?

React Native by default — 90% of features are identical and you ship to both stores at once. Native if you have hard requirements (live activities, complex camera, low-level audio, watch app).

Do you handle App Store submission?

Yes — Apple Developer + Google Play account setup (or working in yours), screenshots, privacy declarations, review responses if rejected. Most apps clear review in 24–72 hours.

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.
