MVP Development Services for Products Where Video, Voice or AI Has to Work on Day One.

MVP development services take a product from idea to its smallest useful version: discovery and scoping, UX and prototyping, a web or mobile build, launch, and iteration based on real usage. Trembit provides the full cycle, with a focus on MVPs whose core feature is real-time video, voice, streaming or AI. We build those parts production-grade from the first release, so the MVP can grow into the full product.

We scope MVPs to about one month of build, after a one-week discovery. That means one core user journey done properly, not every feature on the wish list. When the idea needs more than that, for example native apps on several platforms or a certification such as KBV before launch, discovery shows what fits into the first month and what follows as the next release. You get the timeline in writing before the build starts.

It depends on scope, and we quote after discovery rather than publishing a rate card. The main cost drivers are the number of core features, the platforms (web, iOS, Android), the real-time architecture (peer-to-peer, SFU, managed CPaaS or a custom media server), compliance requirements, integrations, and how much already exists. MVPs are usually fixed price with milestone payments once the scope is agreed.

A prototype shows how the product will look and flow; it’s usually clickable, not working software. A proof of concept tests whether one risky piece works, such as latency on real networks or AI accuracy on your data. An MVP is working software real users rely on, with only the features needed to prove the product. We use all three, in that order when it saves money.

Use the cheapest option you won’t have to throw away. No-code suits back-office tools and early demand tests. A managed video or AI platform is often the fastest route for standard calls. Custom WebRTC or your own AI pipeline pays off when compliance rules out third-party media routing, when you need media features the SDK can’t do, or when per-minute costs grow faster than revenue.

Not if the foundations are right. We cut features, not foundations: TURN relays, reconnection handling, call-quality telemetry, encryption and an architecture that can grow from one-to-one calls to group sessions are in the first release. Phase two then adds features and capacity to the same codebase. The rebuilds we’re asked to fix almost always trace back to one of those being skipped.

Yes, native (Swift, Kotlin) or cross-platform (React Native, Flutter). We often recommend launching on web first when that’s enough to validate demand, then adding native apps in phase two. Where the product depends on the camera, microphone or background audio on phones, we plan the mobile architecture from the start even if the apps ship later.

Yes, and it’s cheaper than retrofitting. Compliance is mostly architecture: where media and data are routed and stored, encryption, access control, audit logs, and which vendors touch personal or health data. We built a KBV-certified psychotherapy video platform in Germany and design to HIPAA and GDPR. We sign GDPR data processing agreements and, for US healthcare work, business associate agreements.

You do. All source code, documentation and intellectual property transfer to you, and we can start under an NDA before you share anything. After launch, most clients keep a dedicated Trembit team for phase two, typically for 1–3+ years. If you’d rather take the product in-house, we hand over architecture documentation and train your engineers.

Yes. We start by assessing what’s worth keeping: often the UI and business logic are fine and the real-time layer or architecture is not. If the product is live and failing, that’s our WebRTC rescue process, which ends with a clear call to fix, partly rebuild or stop. If it’s a prototype that proved demand, we scope an MVP that reuses what holds up.
