Carbon Equity, a climate tech investment platform connecting investors with verified carbon removal and climate solutions, struggled with chaotic CRM operations, inefficient lead prioritization, and rising customer acquisition costs. Through comprehensive HubSpot RevOps implementation (including lead scoring (fit + engagement), automated enrichment workflows, and a systematic event management system) combined with disciplined performance marketing optimization across Google, LinkedIn, and Meta, we reduced average cost per lead by 50%, shortened deal cycles by 30% in 6 months, and transformed a €600K annual ad budget into a predictable investor acquisition engine.
