Helping companies make better decisions through data

Sellforte is a Finnish SaaS company helping businesses turn their sales and marketing data into actionable insight. Our platform uses Bayesian Marketing Mix Modeling (MMM) to measure the true impact of marketing activities across all channels—including offline media, which attribution models typically miss. With Sellforte, companies can continuously identify how their marketing investments and promotions are performing and where to allocate budgets for maximum return.

Why MMM matters

In today’s privacy-conscious world, traditional attribution models fall short. They rely on user-level tracking, face growing technical and legal limitations, and often fail to capture the full customer journey—especially when it comes to offline marketing like TV, print, and in-store campaigns. For many businesses, measurement has been unreliable, fragmented, or available only through expensive, one-off consulting projects. Sellforte changes that by offering a scalable, automated, and always-on solution that delivers meaningful insights—regardless of where the marketing happens.

Built in Finland, expanding globally

Sellforte was founded in 2017 by Juha, Mikko, and Teppo, who are still actively involved today. Our headquarters is located in Otaniemi, Espoo, on the Aalto University campus, at the heart of Finland’s leading tech and innovation ecosystem. Most of our operations are based here, and our team is primarily located in the Helsinki capital region.

But we’re also looking ahead. Backed by venture capital investors, Sellforte is preparing for rapid international growth—especially in Europe and the US. This may involve opening new offices, hiring globally, or relocating talent to Finland or other countries. 

Powered by people

Behind our product is a highly educated and talented team with deep expertise in data science, software engineering, mathematics, and business. Many team members hold advanced degrees, and over half the company works in product or data roles. We're proud of the open, collaborative culture we’ve built—where smart people solve tough problems together and everyone has a voice.

We work with a wide range of retailers and ecommerce companies—including C&A, Douglas, Decathlon, Finnish Design Shop, Verkkokauppa, and Matsmart—as well as media agencies and major ad platforms.
