Discovery Phase

Just like you, we are interested in building a product that will bring a unique value to its audience and win a competitive edge. We’ll help you achieve this with a discovery (scoping phase), which is a process for collecting and analyzing the project information that helps to clarify the goals, limitations, and overall scope of the project.

Our Story

What started in 2017 as a small team of enthusiasts in Lviv has grown into 80+ engineers, designers, and AI specialists united by one goal — to build digital products that truly matter. With offices in Estonia and the UK, we combine design thinking, technical excellence, and startup spirit to turn bold ideas into successful products.

Meet the Team

What Sets Us Apart

Startup-tested at every stage

Our clients have collectively raised $535M in funding. We've been through seed rounds, Series A pivots, and acquisition due diligence — we know what investors scrutinise and how to build products that pass that test.

Design+ engineering under one roof

No coordination tax between separate agencies. Our designers and engineers work on the same product from day one — which means fewer handoff failures, faster iterations, and a product that actually matches the Figma file.

Efficient use of resources

We help you get maximum value at a fair price, with full control over budget and timeline. From the start, we align on expectations, and you can scale your team up or down as needed for flexibility and efficiency.

Commonly Asked Questions

To start working on a project, we have to gather a team of professionals with the relevant expertise that best matches the task at hand. Some of the key experts might be involved in other projects, so there might be a short wait time. But usually, the allocation process doesn’t take longer than one month. Are you looking for an expert in a specific technology, or the deadline is pressing? Email us today, and we’ll try to help you out.

Our team has helped numerous companies to release products with high-quality code, well-tested usability, and a memorable user experience. We build our software testing services on best industry standards (like ISTQB certification), rely on automated testing as a practical approach within CI/CD paradigm, and work with a broad array of real devices and professional testing tools. On top of that, we thoroughly plan and carefully implement the above-mentioned test activities and tasks in a timely manner.

The typical timeframe for developing an MVP for a startup ranges from 1 to 3 months. If it takes longer than two months, inadequate research or poor choice of toolkit may be to blame. However, in rare cases, MVP might require more time for iterations and user validation (up to six months).

We work across the major model providers and open-source ecosystems: Models: OpenAI GPT-4o, Anthropic Claude, Google Gemini, Meta Llama 3, Mistral. Orchestration: LangChain, LlamaIndex. Retrieval: RAG pipelines with Pinecone, Weaviate, and Qdrant as vector stores. Infrastructure: AWS Bedrock, Google Vertex AI, Azure OpenAI Service. We recommend the right stack based on your data sensitivity, cost targets, and latency requirements — not based on what is currently trending.

Cost depends on scope and complexity. As a guide: AI Proof of Concept (PoC) — $8,000–$15,000 (2–4 weeks): validates your hypothesis with a working prototype before you commit to a full build. AI-powered MVP — $40,000–$120,000 (8–16 weeks): a shippable product with core AI features, ready for real users. AI features added to an existing product — from $30,000, depending on model selection, data preparation, and infrastructure requirements. Ongoing costs include inference (OpenAI / Anthropic API usage or self-hosted model infrastructure), vector database hosting, and monitoring. We provide a fixed-fee estimate after a free 30-minute scoping call. Book a meeting to discuss!
