Santtu Koivumäki is Co-Founder of Zero, a Helsinki-based AI-native GTM operating system built to replace traditional CRM with zero-click automation and intelligent AI agents.

Santtu holds a Master of Engineering in Industrial Management from Metropolia University of Applied Sciences and previously served as go-to-market lead across five international markets at Smartly.io.

Having lived the pain of fragmented sales stacks firsthand, Santtu brings deep expertise in revenue operations, customer success, and enterprise SaaS go-to-market strategy.

Santtu and co-founder Tuomo Riekki scaled Smartly.io past $100M ARR before departing in 2022, and went on to build Zero from the ground up, attracting backing from 20VC and Primary Venture Partners.

Zero has raised $13M across pre-seed and seed rounds, with the $10.3M seed considered one of the largest in Finnish tech history, and its platform is already serving ambitious B2B companies across San Francisco, New York, Berlin, and London.
