Product studio · Build + Growth

From zero to app. From app to viral.

Zero2App is a three-person studio. We design and build the product, then work out how it finds its users. Product strategy, front end, back end and data in one team.

Two services, one team

Buy them separately or together. Most products need both.

Zero → App

Development

We take a product from a first sketch to a working app, in the store or in the browser.

  • Discovery, scope and a clickable prototype
  • Web apps and dashboards: React, Next.js, TypeScript
  • Mobile apps with React Native and Expo
  • Back end, databases and payments: Node, FastAPI, PostgreSQL, Supabase
App → Viral

Product strategy

We decide who the product is for, what it costs and how people hear about it, then build the loops that keep them.

  • Positioning, pricing and subscription model
  • Launch plan and first-market entry
  • Referral and affiliate mechanics
  • Retention, analytics and press
AI and data

LLM features, ML models, analytics dashboards and Telegram bots, built by the same people who ship the product.

How a project runs

  1. 01

    Discover

    We agree on the audience, the one job the product does and what to cut.

  2. 02

    Build

    Short iterations. Each one is a working version you can click.

  3. 03

    Launch

    Release, payments, analytics and the first users.

  4. 04

    Grow

    Pricing, referrals, retention and press. We measure and adjust.

Products we built

All five are our own products, and each card names our role. Client projects will join them here.

Questions

Who do you work with?

Founders and small teams who need a product built and a plan for finding its first users. Non-technical founders are welcome.

Can I hire only development or only strategy?

Yes. Some projects start with a strategy sprint and move to development, others go the other way round.

How do we start?

Send a short message about what you want to build and for whom. We reply with questions, and after a discovery call we give you a scope and a price.

Which languages do you work in?

English, Russian and Turkish for projects. Between us we also speak Kazakh, Persian and German.
