Case Study: Mosaic Ventures achieves more accurate first-step qualification of startups with SimilarWeb

Improving the Accuracy of First-Step Qualification for VCs

Mosaic Ventures is a London-based, Silicon Valley‑style venture capital firm investing a $140M Series A fund that evaluates 150–200 consumer-facing startups each month. Their early qualification step required reliable web and mobile traffic trends (up to 18 months) to spot momentum and prioritize deals, so improving the accuracy and efficiency of that first screen was critical.

Mosaic adopted SimilarWeb PRO plus the SimilarWeb API and a Google Sheets integration to pull multi‑site traffic trends side‑by‑side, enabling rapid, trend-focused comparisons across up to 20 sites at once. The solution delivered more accurate first‑step qualification, streamlined screening workflows, and became a daily, indispensable tool for the investment team.
