How much does custom software development cost?

Projects at Tallium typically start from $50,000 for full-cycle product development. Packaged offerings start lower: a Product Concept sprint is $4,950 and a custom AI assistant is $7,950. Most client engagements range from $50,000 to $200,000+, depending on scope and team size. Tallium's rates are up to 50% lower than comparable in-house development and 20-30% below other mature outsourcing companies.

How long does a custom software project take?

Timelines depend on project scope. A product concept and development strategy is ready in 2 weeks. A clickable prototype takes 4-6 weeks. A full MVP is typically delivered in 2-4 months. A core engineering team can be assembled in 1-2 weeks; custom profiles take 3-4 weeks to hire. Dedicated team and ongoing development engagements are open-ended and scale with the client's roadmap.

What is the minimum project size Tallium takes on?

The smallest packaged offering is a Product Concept sprint at $4,950, which delivers a validated product concept, architecture, and development roadmap in 2 weeks. For full-cycle development, the recommended starting budget is $50,000-$100,000, which typically covers an MVP. Tallium does not take on isolated ad-hoc tasks; all engagements are structured around clear business goals and a defined scope.

Does Tallium work with companies outside the Netherlands?

Yes, the majority of Tallium's clients are outside the Netherlands. Active and past clients are based across Europe (UK, Sweden, Switzerland, Germany, Ukraine), North America (US, Canada), Australia, and Israel. Tallium has offices in Ukraine, Poland, Sweden, the Netherlands, and Canada. All project communication is conducted in English.
