Sam Todosiciuc
Founder and CEO of ElasticFunnels and founder of TrackPlay. He writes about payments, MID routing, split testing and funnels for paid traffic.
Nine years as a CTO, then a founder
He built the funnel and payments stack of a direct-response company before building one for everyone else.
Sam spent nine years as CTO of a Romanian direct-response company. He architected most of its internal stack: the funnel system, a custom checkout with multi-MID routing, attribution, and the CRM and call center integration.
The company ran separate tools for what one platform should have done, and revenue leaked between them. In 2023 he left to build ElasticFunnels, where pages, checkout, CRM, attribution and call center share one customer record.
He also founded TrackPlay, the VSL player that counts sales. He writes the ElasticFunnels blog and the Academy tutorials, and the story behind the company is on the about page.
