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.

From a shopping app to a leading marketplace: 500,000 users and growing

Prostor app home screen with product offers

In the first few months after launch, over 50,000 users downloaded the app from Google Play and the App Store. After a year and a half, that number has grown to around half a million. Today, Prostor isn’t just a shopping app. It’s a marketplace, opening new revenue opportunities for partners that sell alongside Prostor.

Moving forward, we are working on new features, like a habit tracker and in-app rewards, and improving the application based on customer feedback.

More than 10,000 downloads without any marketing efforts

Although the marketing campaign to promote the app is yet to start, more than 10K users have already downloaded the app from Google Play and App Store. Moving forward, our team is focused on implementing new features including push notifications, favorites, and ratings, and improving the application based on customer feedback.
