Harsha Venkatesh

I’m a B2B customer success professional with 5+ years of post-sale account ownership across SaaS, services, and enterprise environments. I currently manage a £1.6M ARR book of business at an Ireland-based AI SaaS platform, focusing on measurable retention and growth outcomes.

I’m known for lifting product adoption, reducing time-to-value, and growing NRR through health-score-led playbooks, structured QBR and EBR programmes, and proactive churn avoidance. In my current role, I built a HubSpot health-scoring framework to flag at-risk accounts 60+ days out—delivering 100% GRR and zero unplanned churn for my SMB segment.

I also translate customer insight into action. I rebuilt onboarding to cut time-to-value from 45 to under 25 days, created a separate SMB onboarding track (cutting TTFV 40% and improving activation to 95% with zero drop-offs), and used HubSpot-triggered workflows to lift adoption from 22% to 47% in 60 days while reactivating 14 stalled accounts.

Earlier, as a Client Success Lead, I delivered 117% NRR and ~£100K in expansion revenue by tying per-account 90-day success plans to measurable ROI and running quarterly and executive business reviews. Before that, I worked as a client relationship manager in government and private-sector B2B accounts, growing contract value by 30%, converting annual contracts into 3-year commitments, and securing additional managed revenue through targeted stakeholder outreach.
