Trossa AB

What Trossa AB does

Trossa AB is a privately held, Stockholm-headquartered sustainability consulting firm founded in 2010 that serves both private and public-sector clients across Sweden. The firm employs 27 senior consultants with over 200 years of combined experience, covering a deliberately broad sustainability stack: climate and biodiversity, chemicals and materials, life cycle analysis (LCA) and circularity, regulatory compliance, due diligence in value chains, ESG advisory for financial actors, sustainability reporting and communication, strategy and governance, and interim/staffing. Service delivery is project-based, conducted on-site, remotely or hybrid, with offices in Stockholm (HQ on Södermalm) and Östersund, plus consultants distributed in Göteborg, Borås and Kalmar. Notable long-term client engagements include Lantmännen (since 2015) and a 10+ year role as independent third-party reviewer for Möbelfakta AB's ISO 14024 eco-label.

The firm's technology footprint is modest but proprietary: Carbon+Alt+Delete is an in-house, ISO 14064-1-certified cloud tool for GHG Protocol climate accounting (data collection, scenario simulation, audit), and SimaPro is used for life cycle assessments and EPDs. Trossa Academy is a separately branded education arm delivering in-person courses in Stockholm. Revenue is generated almost entirely through professional services — bespoke advisory assignments, interim sustainability staffing, and training — with pricing largely quote-based and publicly disclosed only for training (e.g., SEK 11,500 for a sustainability reporting course for SMEs).

The go-to-market is sales-led and relationship-driven: the firm relies on referrals, long-cycle partnerships, content marketing via its website and LinkedIn, educational events (lunch seminars, webinars) and case-study publishing. No external investors, M&A activity or funding rounds are disclosed, and the company operates as an independent, flat partnership-like structure.
