Fullstakk Marketing AS

Fullstakk Marketing AS is a Norwegian digital marketing agency founded on May 10, 2016. The company was established with the objective of optimizing digital marketing efforts through data-driven and transparent methods to deliver demonstrable economic growth for its clients. The firm is led by CEO Fridtjof Hødnebø and CPO Markus Ekornes Myhre. Since its inception, the company has experienced rapid growth and was recognized as a Gaselle company in both 2020 and 2021. In June 2025, Fullstakk was acquired by Done.ai Group, positioning it as an operating subsidiary while still being formerly venture-capital-backed by Tjuvholmen Ventures.

Operating as a growth agency, Fullstakk provides strategic advice and operational specialists to transform a client's digital marketing into a growth engine. The company serves a diverse client base, including B2C and B2B businesses, service providers, and membership organizations. Its business model is centered on providing a comprehensive suite of digital marketing services. These services include paid search, social media advertising, programmatic advertising, search engine optimization (SEO), conversion rate optimization (CRO), and data analysis. The agency employs a proprietary methodology called the "Fullstakk-metoden," which systematically structures all growth-contributing activities along a six-phase customer journey: awareness, traffic, conversion, retention, revenue, and referral.

A core component of their service is the "Vekstriggen" (the growth rig), a proprietary analysis and growth tool they developed. This tool consolidates all relevant data from various marketing initiatives and campaigns into a single, real-time updated report. This provides stakeholders with a unified overview of which activities are effective and when, allowing for continuous testing, measurement, and optimization. By breaking down all factors contributing to growth into measurable hypotheses, Fullstakk aims to maximize the return on their clients' marketing investments. The agency's approach is designed to be effective not only for direct sales but also for organizations with subscription models by optimizing the entire growth journey.
