What clients say
What impressed me most was how quickly he understood our vision. Took our messy requirements and turned them into clean, scalable architecture. Felt like working with a co-founder.
Robert Steer
CEO at XRP Name Service
Jay was instrumental in launching multiple Web3 startups under our umbrella. He led teams, drove products from concept to MVP, and his work helped secure millions in funding.
Wayne Loyd
Founder at NFT Tech
We needed our points trading marketplace done fast, and Jay delivered the entire thing in 6 weeks. His technical skills and execution speed were crucial in helping us raise $2.77M. Honestly couldn't have done it without him.
David Zhu
CEO at Pichi Finance
Honestly, the app turned out better than I imagined. The UX is so polished, and our users keep telling us how intuitive everything feels. Super grateful for the execution here.
Minje Kim
Co-founder at Coach Chad
We needed someone who could build our infrastructure from scratch and scale it fast. Everything he built has been rock solid since day one, even under heavy load. Really impressive work.
Ian Clark
VP Engineering at Banxa
Our site was painfully slow before the migration. Now it's 80% faster and we finally have the analytics to understand what's actually converting. This was a game-changer for our business.
DJ Dikic
Founder at Tint
We launched ahead of schedule and the mint handled crazy traffic without breaking a sweat. Hit 400 ETH in sales and the platform's been solid ever since. Really happy with how everything turned out.
Christian Gravel
Founder at Crash Test Joyride
I was nervous about the mint going smoothly, but it was flawless. Gas-optimized contracts, zero issues during high traffic, and we sold out completely. Couldn't have gone better.
Alex Nguyen
Co-founder at 0xPunks
The whole marketplace was done in a week. I know that sounds crazy, but the quality was incredible. Our users love it and we haven't had a single major issue since launch.
Mark Edwards
Founder at Superagent
Building an NFT game is tough, especially the smart contract security side. Everything worked perfectly and the attention to detail really shows in how engaging the experience turned out.
James Hartley
Co-founder at Chainlords
I started Saren Studio to give founders the kind of partner I always wanted: someone who can shape the product, build the experience, and ship the full stack under real deadlines.
Jay Kumar, Founder
Frequently asked questions
Yes, 100%. You own everything we build. All source code, assets, and infrastructure are yours from day one. We do not retain any IP or licensing rights.
Scope changes are normal in early-stage builds. We communicate transparently, re-scope together, and adjust the timeline and budget before moving forward. No surprises.
No. We are a development studio. We work with your existing designs, your in-house designer, or a design partner we can recommend. This keeps builds focused and fast.
Most MVPs ship in 4 to 8 weeks depending on scope. We scope tightly, cut what does not matter for launch, and get a working product into users' hands as fast as possible.
Yes. Our ongoing development plan covers feature work, iterations, performance improvements, and infrastructure. You get a dedicated senior developer working on your product continuously. Pause or cancel anytime.
It starts with a short intro call to understand your product and goals. From there, we scope the build, agree on milestones, and start development. You get async updates via Slack or Telegram and a live staging link throughout.
