Didomi

A law forced every EU site to ask cookie permission. Didomi turned that legal chore into a yearly subscription.

Mandatory demand. GDPR and Google both make a certified consent banner compulsory to run EU ads. Didomi turned that into 1,500+ clients across 35 countries. But consent tech keeps commoditizing.

About $50M ARREstimateest. ARR (Latka, 2026)
2026source:
Latka pegs 2026 ARR at $40-60M ('about $50M') for the combined Didomi group post the 2025 Sourcepoint + Addingwell buys; standalone Didomi was closer to $15-18M in 2025, up from about $10M end-2023. Didomi itself publishes no revenue figure.
Client and country counts are Didomi's own (pre-2025 M&A); the ARR is a Latka estimate for the post-M&A combined group, since Didomi discloses no revenue.
About $50M ARR (Latka est., 2026, combined group post-M&A); Didomi itself discloses no revenue, only 1,500+ clients across 35 countries.

Revenue is NOT first-party. Didomi has never published an ARR figure. The headline 'about $50M ARR' is Latka's 2026 estimate for the combined Didomi group (post the 2025 Sourcepoint + Addingwell buys), given as a $40-60M range; Latka separately put standalone pre-acquisition Didomi at about $15-18M for 2025, up from about $10M end-2023. Growjo estimates similarly. Verified first-party from Didomi's own site (didomi.io/blog/didomi-sourcepoint, raw HTML): 'over 1,500' clients across '35 countries' before the 2025 acquisitions, and Sourcepoint's '200 global enterprise customers.' Funding is press-confirmed: $127.6M across 3 rounds, plus an $83M Marlin Equity investment in 2025 that funded the Addingwell buy (Clipperton press release, verified verbatim). Treat revenue as an estimate (sourced=EST) for a now-larger combined entity; client/country counts and funding are first-party or press-confirmed. verified=false because no revenue figure is first-party. We never score you.
