Infinum

Infinum is a digital product and engineering company founded in 2005, when two engineering students won an app-building contest and used the prize money to start the business. It has grown to roughly 400 people (396 across 22 teams, by its own 2025 count) and now describes itself as an AI-native, end-to-end digital solutions provider.

The company works from seven offices: New York, London, Amsterdam, Zagreb, Ljubljana, Skopje and Podgorica. Clients bring it product ideas, apps and platforms that need strategy, design and engineering together, and it reports more than 1,000 product launches for around 500 clients.

Key features

• Mobile apps. Native iOS (Swift, SwiftUI) and Android (Kotlin, Compose), plus cross-platform work in Flutter, React Native and Kotlin Multiplatform.
• Web platforms. Front ends in React, Next.js and Angular with back ends in Python, Ruby on Rails and Node.js.
• Strategy and design. Product strategy, product design and brand experience sit alongside engineering.
• AI and data. AI transformation consulting and AI and data engineering are listed as separate service lines.
• IoT, enterprise and security. Custom IoT solutions, enterprise platforms and cybersecurity services cover connected devices and larger systems.
• Small delivery teams. Infinum says small teams of three to five experts work through phases it calls understand, scope, build, deploy and scale, favouring proofs of concept over long planning.
• Knowledge sharing. It runs an Academy for designers and developers, publishes handbooks and contributes open-source code.

Who it is for

Infinum fits mid-size and large companies that want a single partner for a new digital product, from discovery to launch, as well as product organisations that need an agency to supplement their own staff. Its contact form names three routes: building a new digital product, acting as an agency partner alongside internal teams, and taking on outsourced production. Its client list includes large consumer and enterprise brands.

Pricing at a glance

Infinum does not publish rates. Pricing is quoted per project after you describe the initiative through its contact form, whether the work is a new product, a partnership that adds capacity to your team, or outsourced production.

Things to consider

• Mainly European delivery. Most offices are in Europe, with sales presence in New York and London; plan overlap hours if your team is in Asia or the Americas.
• Full-service scope. The model works best when you want strategy, design and build together; very small, single-skill tasks may be better placed elsewhere.
• AI-first process. Infinum says AI is built into its delivery method; ask how AI tools are used on your code and data and what review applies.
• No public rate card. Budget only after a scoped proposal.
