About us

Not another dev shop

Team collaboration
We’re not a dev agency on the outside.
We’re your product team on the inside.

We work with your tools, move at your pace, and give you clear answers. Not vague timelines. No ticket silos. No disappearing acts. Just product-focused devs who think beyond the code.

We build like it’s our business, because your success reflects on ours.

We stay close to the products we build and many of our client relationships last 3+ years, because we keep delivering value.

Less agency, more ownership. That’s Celestify.

CTO-level thinking, baked in

Every project gets senior engineering oversight and strategic guidance. No juniors left unsupervised, no random tech decisions. You get a team with opinions, experience, and people who care about the outcome as much as you do.

For product-first founders

We’ve built startups, shipped products, managed messy projects, and fixed bad agency code. We think in terms of added value, not just tickets. Whether you’re launching from zero or scaling a live product, we bring speed, strategy, and clarity, without adding noise.

No chaos. No jargon. Just results.

You’ll always know what’s happening, what’s next, and what it costs. Async updates, open Slack/Teams access, fixed pricing, and a dev team that gets things done without you chasing.
