What Sustain Business Aps does
Sustain Business Aps (operating as SustainBusiness) is the ESG consulting division of Danish accounting firm Martinsen Rådgivning & Revision. The firm serves Danish small and medium enterprises that must comply with EU sustainability frameworks including CSRD, ESRS, and the VSME standard. Headquartered in Risskov (Aarhus), Denmark, with a team of 7 employees, SustainBusiness positions itself as a translator of complex sustainability regulation into practical, SMB-actionable deliverables, using the 'jordnær ESG' (down-to-earth ESG) framing to differentiate from theoretical compliance approaches.
The service portfolio is organized around three core verticals — climate accounting (Klimaregnskab), ESG reporting, and LCA/EPD documentation — each offered in tiered subscription packages (Basis, Udvidet, Premium) structured as multi-year contracts. Adjacent offerings include ESG strategy development, double materiality analysis, interim sustainability staffing, and customized corporate training courses. SustainBusiness also builds ESG industry analyses (Brancherapporter) and a supplier training program that helps suppliers deliver Scope 1-3 climate data to customers, extending the value chain of the engagement.
Technically, the firm has built Allasia, a proprietary AI model trained on the Danish Consumer Ombudsman's guidelines for environmental marketing claims. Allasia analyzes text-based company communications to flag potentially misleading environmental claims with a claimed 92% precision in under 30 seconds and is offered both as a standalone Greenwashing Check service and as embedded intelligence within the firm's consulting engagements. The company operates a sales-led, content-driven go-to-market combining direct outreach to Danish SMBs, free ESG consultations, customer testimonials, webinars, and an active LinkedIn and article library to generate inbound leads; revenue is generated from project-based consulting fees, subscriptions, time-based interim placement, and training engagements. As of 2026, the firm is being fully integrated into Martinsen under the unified 'Martinsen — rådgivning, revision og ESG' brand.
