"Sellforte has brought new clarity to how we track and allocate our marketing budget."

Liam Shannon

"We feel that this provides us a competitive edge in a highly-competed environment."

Stefanie Hübner

VP of E-Commerce, Douglas

"It really creates an impact. Over the last few weeks, we have reworked our entire marketing budget for the next year using the Sellforte insights."

Maik Kleinschmidt

Director, Marketing Europe, C&A

"We wanted to measure our media and marketing strategy change and chose Sellforte as they understand the complex grocery retail world with a combination of promotions and media."

Karoliina Kinnunen

Media & Digital Marketing manager, Lidl

Media Planner Agent

Causal Marketing Mix Modeling

Reveals the true ROI for each channel and campaign by measuring their incremental sales impact.

Geo Lift Testing

Used for calibrating and validating the Marketing Mix Model for increased accuracy

Attribution Analytics

One dashboard for MMM and Attribution. Enables comparing Last-Click and Ad Platform attribution to MMM.

Media metrics

Media Metrics = Impressions, Clicks, Conversions, AOV.. Used for uncovering the drivers of ROI changes.

Transition from Attribution to Incrementality

Last-Click and MTA are biased to favoring bottom-of-funnel channlels (such as branded search) and undermeasuring Paid Social. At the same time, Ad Platform attribution is inflated.

Sellforte's incrementality-based measurement reveals the true incremental revenue contribution of each channel.

Measure the Full Funnel, not just the Last Click

Start measuring Awareness channels, such as Paid Video and Paid Social Awareness, which don't show up in click-based measurement.

Reveal the true potential of Paid Social, which can be 2x - 17x more effective than what Last-Click shows.

Evaluate level of saturation in Demand Capture channels, such as branded search or retargeting campaigns.

"I introduced the Sellforte tool at C&A, because I was looking for a tool providing actionable insights on a continuous base."

Gina De Ryck

Head of Consumer Insights and Analytics, C&A

"We've been able to optimize how we invest for user acquisition and keeping our current customers. Sellforte is our trusted partner in marketing effectiveness."

Ulla Koivula

Co-founder, Chief Marketing & Digital Sales Officer, Moi Mobiili

"As marketing is getting more and more data-driven, it’s crucial for us to be able to measure our marketing investments on ongoing basis."

Maiju Laurén

Chief brand and design officer, Finlayson

"It might seem tempting to build your own MMM solution. However, do not underestimate the time, money, and resources it takes to build an MMM solution that can compete with the top global solutions especially if you want to use MMM for an omnichannel marketing strategy."

Maksim Iavorskii

Head of Marketing Intelligence, Peek & Cloppenburg

"We considered building our own solution as well. However, we quickly realized that if there's already a company dedicated to this with years of product design behind them, we couldn't match that level of expertise. So, it seemed wiser and more efficient to purchase it."

Johanna Kuparipuro

Paid Media Lead, Finnish Design Shop

"We aim to understand the true impact of our media investments—not just where clicks happen, but how different channels drive incremental sales uplifts."

Kimberly Koay

D2C Performance Marketing Manager, Horizn Studios

"For me and my team it’s now easier to prove our decisions when we’re having the numbers and hard data behind the decisions."

Sami Särkelä

Head of Brand & Digital, Gigantti

"I'd recommend Sellforte to all agencies or companies investing in several digital channels at the same time. Resource allocation in fact cannot be done by analyzing the tools individually, each with its own attribution model."

Gioacchino Spinello

Head of Data Analytics, WMR Group
