Marr Labs is led by a team with extensive experience in AI and technology, refined through years of collaboration and a track record of bringing cutting-edge innovations to market.

Founders Dave Grannan, Han Shu, and Ghinwa Choueiter, together with Joe Pirone and Chris Barnett, collaborated at Vlingo to create the technology powering Siri and Samsung’s S-Voice. Dave and Chris reunited at Light, where Rob Bajohr joined the team, driving its growth and eventual acquisition by John Deere.  After Han’s startup Wyth was acquired by Airbnb, Han led Airbnb's ML and AI groups and built a team that drove large-scale innovation.

The reunion of this exceptional group at Marr Labs represents a rare convergence of talent and proven teamwork, poised to deliver transformative technologies to market.

Dave, Han, and Ghinwa first joined forces at Vlingo, where they developed the technology that powered Siri and Samsung’s S-Voice. Their groundbreaking work at Vlingo set the stage for modern conversational AI.

The emergence of Large Language Models has created a new opportunity to advance this field even further. Reuniting with other key collaborators from their Vlingo days, the founders have come together again at Marr Labs, building on their shared history of innovation and teamwork to transform the next generation of conversational AI.
