About Sellforte

Sellforte is a Finnish SaaS company helping ecommerce and DTC brands make smarter, data-driven marketing decisions. Our platform combines Marketing Mix Modeling (MMM), incrementality testing, and attribution correction in one always-on solution, so marketing teams can see what truly drives incremental revenue, not just what ad platforms claim credit for.

With Sellforte, brands can continuously see how their marketing investments perform across channels and markets, and where to allocate budgets for maximum return. It is a scalable, automated, and always-on solution that replaces fragmented, one-off consulting with a living system for continuous marketing optimization. You can read more about the solution here and see a demo here.

Our customers include leading ecommerce brands such as bonprix, Odlo, Represent, Finnish Design Shop, and Azzas Group, who use Sellforte to connect the dots between campaigns, media investments, and actual business results. In addition, we collaborate with media agencies and key industry partners like Google, Meta and TikTok to advance marketing measurement practices and help customers achieve the best possible outcomes.

Founded in 2017, Sellforte is built and headquartered in Espoo, Finland, on the Aalto University campus at the heart of Finland's tech and innovation ecosystem. Our international team of about 50 professionals combines expertise in data science, software engineering, and marketing analytics.

Our customer base is growing, and to support this growth we are looking for a Customer Success Manager with a strong technical and analytical edge to make sure our ecommerce customers get the most out of Sellforte's solution.

The role

As a Customer Success Manager, you are the bridge between our customers and our data science team. You combine a solid understanding of digital marketing data with hands-on technical problem solving, and you make sure customer needs turn into clear, actionable work for our team and into real impact for the customer.

• Coordinating customer communication across channels (Slack, Teams, Google Chat), understanding requirements and questions from a large number of customers, and staying on top of what each customer needs

• Translating customer questions into clear, actionable tasks for our data scientists, and solving smaller problems yourself so the team can keep moving

• Leading daily meetings with our data science team (currently seven data scientists), allocating tasks and managing the team's task management

• Troubleshooting data connectors (Fivetran), including sync and authorization issues that other team members are unable to solve

• Calibrating customers' Marketing Mix Models and making implementation decisions based on technical limitations and business context

• Answering customer questions about digital marketing data and providing light analysis on questions customers raise about their own business

• Researching how customers' data streams can be integrated into Sellforte's product

• Managing the customer relationship day to day: training customers on the Sellforte UI, running monthly catch-up meetings, and managing expectations toward customers

• Explaining and communicating how the Sellforte product works, both internally and externally

• Experience in digital marketing and/or ecommerce, with a good understanding of how performance marketing works in practice

• A good understanding of digital marketing and ecommerce tools, for example GA4, Meta Ads Manager, Google Ads, and Shopify

• An analytical mindset and hands-on experience in analytics, with drive to solve customers' problems and present actionable solutions

• Excellent communication and facilitation skills: ability to communicate clearly with both technical and business audiences, drive alignment across teams, and confidently lead customer meetings

• Strong project and task management skills, with the ability to keep many threads moving at the same time

• Professional proficiency in English; other languages (especially German, French, or Spanish) are a plus

What we offer

• A globally unique product: Contribute to building a one-of-a-kind SaaS platform for marketing measurement, used by leading ecommerce and DTC brands to make smarter, data-driven decisions.

• An interdisciplinary, international team: Join colleagues from more than eight nationalities across three countries, combining expertise in data science, engineering, business, and more.

• Low hierarchy, high trust: Work in a flat organization where ownership, transparency, and collaboration are part of everyday life. We value initiative and make sure work stays enjoyable along the way.

• Flexible ways of working: We support both remote and office work. Some of our team members work mostly at the office, while others work mainly (or even fully) remotely. However, in-office work may be preferred or required in some situations, such as during onboarding to get up to speed, for important meetings, or for projects that require close collaboration.

• Salary and bonus

  • Junior/Medior level: €3,800 to 4,500 per month + 10% OTE bonus based on customer KPIs

  • Senior level: €4,500 to 5,500 per month + a tailored bonus program based on experience and performance targets
