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.

Active and past clients are based across Europe (UK, Sweden, Switzerland, Germany, Ukraine), North America (US, Canada), Australia, and Israel.
