Data-driven marketing decisions with real business impact

Sellforte is a Finnish SaaS company that helps businesses optimize marketing for measurable business impact. We accurately measure marketing performance across all channels using advanced Marketing Mix Modeling (MMM), capturing the true incremental effect of both digital and offline marketing.

Sellforte turns measurement into action through clear visualisations, AI-powered summaries, and actionable recommendations. Unlike one-off consulting projects, our always-on platform delivers accuracy, automation, and scalability. It continuously improves marketing decisions and increasingly automates optimization directly into digital platforms.

Built in Finland, expanding globally

Sellforte was founded in 2017 by Juha, Mikko, and Teppo, who remain actively involved in the company today. Our headquarters is 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.

We’re now expanding our customer base internationally, especially across Europe and the United States. As we continue to grow, we may also establish new offices or hire talent in these and other markets.

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.

Real-world impact

Our customers include leading B2C brands such as C&A, Lidl, and Kik, who use Sellforte to connect the dots between campaigns, promotions, and actual business results. We also collaborate with media agencies and key industry partners like Meta and TikTok to advance marketing measurement practices and help customers achieve the best possible outcomes.
