What Zalster does
Zalster is a Gothenburg-based (Sweden) hybrid digital agency and ad-tech platform that manages and optimizes paid social advertising primarily for e-commerce businesses in the Nordic region (Sweden, Norway, Denmark, Finland). Founded in 2015 by Albin Stööp, Antonios Kioksoglou, and Nathanael Andersson — operators who began investing in Facebook advertising around 2011 through discount service Let's Deal — the company operates as a Meta Business Partner and extends coverage to TikTok, Pinterest, and Snapchat. Its core product is a proprietary in-house optimization tool with built-in machine-learning algorithms that automate ad rotation, budget allocation, and time-of-day selection; a complementary suite of technical services (Conversions API implementation across all four platforms, Google Tag Manager, GA4 migration, and GDPR cookie consent) is sold as add-on professional services.
The company monetizes through quote-based subscription contracts (monthly or annual, prepaid and non-refundable) plus separate time-and-materials billing for technical implementation work. Sales are conducted via a direct, consultation-led motion — HubSpot meeting bookings, contact forms, and weekly/daily account engagement — targeting enterprise e-commerce brands (e.g., Lyko, Ellos Group, Didriksons, Dreams) alongside smaller Nordic retailers. An upcoming Omni-Channel Reporting Tool (2024 waitlist) signals a planned extension from managed service into productized measurement/analytics, with operating entities Zalster AB (Sweden) and Zalster, Inc. (USA) indicating a cross-border structure though primary commercial focus remains the Nordics. Disclosed headcount is in the 11–50 range and total institutional funding is small (~$343K from Wellstreet in May 2017), implying predominantly bootstrapped growth.
