CallStream AI Secures Seed Investment from Superhero Capital

CallStream AI, a company transforming how businesses capture and leverage mobile calls, has raised seed funding led by Superhero Capital. The investment supports CallStream AI’s mission to turn mobile calls into actionable business insights by seamlessly integrating them into enterprise systems such as CRM and ERP. The funding will be used to further support the company’s next stage of growth.

“From the very first conversations, it was clear that Superhero Capital shares our excitement about the future of AI in telecommunications. They see the same opportunity we do: mobile calls are an untapped superpower in modern business. With them backing us, we’re building smarter conversations: turning mobile calls into actionable insights and helping enterprises unlock the full potential of every call. We’re proud to have Superhero Capital in our corner as we keep making enterprise telecommunication a little more heroic, every day,” says Tero Hartikainen, Founder and CEO at CallStream AI.

The seed round was led by Superhero Capital, a venture capital firm known for backing ambitious early-stage technology companies across Finland and the Baltics. Superhero Capital focuses on founders building scalable, category-defining businesses and has supported multiple companies operating at the intersection of software, data, and emerging technologies.

“What made this an easy decision for us was the team’s real-world telecom experience, early traction with operators, and a clear plan to turn voice into a scalable data layer for enterprises. We are proud to support Tero Hartikainen and the whole CallStream AI team as they build something bold in a traditionally hard industry,” says Gytenis Galkis, Partner at Superhero Capital.

Despite the growth of digital communication, mobile calls remain one of the least leveraged sources of business data. This funding highlights a growing recognition of the opportunity to bring AI-driven intelligence into everyday mobile conversations. By backing CallStream AI, Superhero Capital is supporting a shift toward making mobile calls an integral data source for enterprises, enabling better visibility, smarter decision-making, and stronger integration. 

The newly raised capital will support CallStream AI’s next stage of development, including enhancing its AI-driven call intelligence capabilities, deepening CRM and ERP integrations, and expanding distribution through telecom operator partnerships.

As CallStream AI enters its next phase of growth, the company remains focused on one goal: ensuring that every mobile call becomes an opportunity for better decisions and smarter business outcomes.
