What New York Business Owners Ask First

Platform Development covers native and cross-platform app builds — Android, iOS, React Native, and Flutter. AI & Intelligence covers adding AI/ML-powered features, like chatbots, recommendations, and predictive analytics, into a mobile app.

Most clients start with a free consultation — we ask about your platform needs, timeline, and goals, then recommend the right service or combination.

Yes. We sign an NDA before any detailed discussion, and standard IP-assignment language is built into every contract.

You do, fully, upon final payment. There’s no vendor lock-in — you receive the complete codebase, credentials, and documentation.

It depends on platform and scope — a Flutter or React Native build often moves faster thanks to a shared codebase. We’ll give you a concrete timeline after discovery.

Yes — we regularly audit and take over existing codebases, whether the original team is unavailable or you’re switching partners.

Every engagement includes ongoing support after launch — bug fixes, OS updates, and feature iteration.

Fully in-house and Brooklyn-based. No subcontracted teams, no timezone hand-offs you weren’t told about.
