Sara Beykpour is the co-founder and CEO of Particle, an AI-powered news app that summarizes the day's stories and shows readers how coverage differs across the political spectrum. She spent more than a decade at Twitter shaping products like Vine, Periscope, and Twitter Blue before leaving in 2022 to build Particle with former Twitter engineer Marcel Molina. The company launched publicly in November 2024 and has raised roughly $15.3 million, including a $10.9M Series A led by Lightspeed.
Kayvon Beykpour is the co-founder and CEO of Macroscope, an AI-powered code intelligence platform that raised $40M in funding. Before Macroscope, he co-founded Periscope - the live video streaming app acquired by Twitter in 2015 for a reported $100 million - and spent seven years at Twitter rising to Head of Consumer Product. A Stanford Computer Science graduate of Iranian heritage who grew up in Northern California, Beykpour has a pattern of building tools that make invisible things visible: first the world's live moments, now the inner workings of engineering teams.
