Hornet
Hornet is a queer social network and mobile app for gay, bi, trans, and queer men, built around community, content, and connection rather than pure hookups. Launched in 2011 and led by founder and CEO Christof Wittig, the company (operating as Hornet Networks / Queer Networks) has grown to more than 30 million members, positioning itself as one of the largest gay social platforms in the world and a frequently cited competitor to Grindr.
Willow
Willow is a San Francisco startup building voice-first interfaces that turn natural speech into polished text across every app on Mac, Windows, and iPhone. Founded in 2024 by Stanford dropouts Allan Guo and Lawrence Liu and backed by Y Combinator, Willow promises roughly 3x the accuracy of built-in dictation with ~200ms response time, automatic filler-word removal, style-matching, and an AI mode that reshapes rough spoken notes into finished messages. The company raised $4.2M in seed funding and has grown roughly 50% month over month, with early enterprise users including Uber, Heidi Health, and Zego.
Alex Westner
Alex Westner is the co-founder and CEO of Xander, a Raleigh-based startup building AR smart glasses that print live captions of in-person conversations directly into the wearer's field of view. An MIT Media Lab-trained audio engineer who spent nearly two decades shipping sound software (including the Emmy-winning iZotope RX, nicknamed the Photoshop for Sound), Westner now turns his obsession with the cocktail party problem into a self-contained, no-cloud, no-phone device that helps people follow conversations they can no longer fully hear.
Nathan Sharp
Nathan Sharp is the Co-Founder and CEO of Retro, a friends-only photo journal app built on the belief that social media can be better - more intimate, more honest, more for the people you actually care about. A Harvard grad and Dartmouth Tuck MBA, Sharp spent six years at Meta where he helped launch Instagram Stories in 2016 before leaving to build Retro with his co-founder Ryan Olson. Backed by Thrive Capital, Dylan Field, and a constellation of top-tier VCs, Retro hit #1 photo app in Canada and broke into the US top charts in 2025, proving that people still want a social app that actually feels like talking to friends.
