About me

I've spent my career in B2B sales and GTM, starting in sales at Google in New York, then moving into account strategy and later becoming a Senior AE in Berlin's startup ecosystem. After years of running full sales cycles, I became focused on the systems behind predictable growth. In 2023, I founded Harochi to build those systems for B2B companies. We've worked with companies including Aikido Security from Seed through unicorn status, HeyReach during its growth from $3M to $15M ARR, plus distil labs, Finally, Vidyard, and Vivid Money. In 2024, the systems we built generated more than $1.9M in closed opportunities from 437K cold emails and 35K LinkedIn messages. Harochi is now a five-person team with most client delivery processes automated, and I mentor early-stage founders through HubSpot for Startups. I'm most useful when you need a second opinion on an expensive GTM decision. Book me to discuss: * Why your outbound isn't converting * The pipeline math behind your revenue target * How to move from founder-led sales to a repeatable GTM motion * What your GTM team, CRM, data, and automation stack should look like * Where AI actually belongs in your GTM process * What to fix before hiring another sales rep * How to get the founder out of the critical path of every deal I work best with B2B founders who already have some traction and need to turn sales activity into a system that can scale without depending on them.
