Our services

Any software product. Built around your needs, not our template.

We deploy the product on the client's servers or in their cloud and hand it over up and running — with access credentials, documentation and team training.

We choose the most modern and best-fit technologies to build your product.

A great idea let down by execution. We fix that.

( What we do )

Founders and companies know exactly what product they need, but rarely have a team that can build it quickly, securely and on a modern stack. That is what we provide: a strong, AI-accelerated engineering team that turns your requirements into a working product — a bot, a website, a platform, an agent system or an app.

A small team and a direct line to the people who design and write the code.

About the studio

Why us

Why work with us?

We believe a good product starts with a good working relationship. No complex processes and no middlemen — just a team that responds fast and delivers well.

  1. 01

    Direct access to developers

    No go-between managers. You talk to the people who design and build your product. Faster, more precise, and no ideas get lost along the way.

  2. 02

    Transparent process

    A task board, weekly demos and access to a staging environment from week one. You always know what's done, what's in progress and what's next.

  3. 03

    The product stays yours

    We deploy the product on your servers or in your cloud and hand it over up and running: source code, infrastructure, documentation and access are all yours. No dependence on us after delivery — though we're here for support.

  4. 04

    AI built into the process

    We use agentic systems in our own development: code review, testing, documentation. That's why we deliver several times faster without compromising quality.

Process

From brief to launch — transparent, in sprints.

  1. 01

    Brief and goals

    We break down the task, audience and success metrics. Within 1–2 days you get a clear estimate and plan.

  2. 02

    Prototype and architecture

    A clickable prototype, a data model and the choice of stack. You see the product before development starts.

  3. 03

    Development in sprints

    Weekly demos, a staging environment, changes along the way. No surprises at the end.

  4. 04

    Launch and growth

    Release, monitoring, analytics, support. We help you grow and add features.

How much does development cost?

For reference: a messenger bot starts from 60,000 ₽, a website from 120,000 ₽, a Mini App from 150,000 ₽, a mobile app from 400,000 ₽, an agent system from 500,000 ₽, and a marketplace platform from 1,200,000 ₽. All prices are for reference and depend on the scope of work: we quote the exact cost after reviewing your specification. You can get a preliminary estimate right away by filling in the brief on our site.

What are the timelines?

A bot or landing page — from 1 day. A website or Mini App — from 3 days. A mobile app — 8–14 weeks. A platform — an MVP in 8–12 weeks, then further development in sprints.

How do you choose technologies?

We choose the highest-quality, most modern solutions for your task and your product's horizon — no outdated technologies and no lock-in to a single stack.

Can we start small and expand?

Yes, that's our core approach. We launch an MVP, measure, and add features. The architecture is designed for growth from day one, so there's no need to rewrite.

Who owns the code and data? Where is the product hosted?

You do. The repository, servers, domains and access are all registered to you. We deploy the product on your servers or in the cloud of your choice and hand it over up and running: with documentation, monitoring and team training.

Do you work with enterprises and the public sector?

Yes. We have experience with 152-FZ (Russia's personal data law), on-premise deployment, integrations with 1C and SAP, and isolated networks with no internet access.

What happens after launch?

Support, monitoring and development under an SLA. You can get support from us or hand it over to your own team — the code and documentation make that possible.

How do we get started?

Send a request on our website or message us on Telegram. We'll reply within 2 business hours, discuss your task and send an estimate.
