Felicis founder Aydin Senkut is celebrating his 19th year as an institutional early-stage investor by announcing the firm’s biggest fund yet: a $900 million Fund X.

This follows the $825 million Fund IX raised in 2023 and the $600 million Fund XIII raised in 2021. Felicis, a seed and Series A firm, is known for backing a long string of successes, including Ayden, Bonobos, Ring, Shopify, and Twitch, among others. Since being founded in 2006, Felicis has backed over 50 unicorns and had over 125 exits, it says.

Lately, Felicis, like most VCs, has been all over AI. Its portfolio now includes, for example, Browser Use, Poolside, Runway, and Supabase. “We believe dozens of $100B+ AI companies will emerge this decade (not merely $1B or $10B),” Felicis wrote in its blog post, adding that 70% of its active portfolio are what it considers AI-native startups. 

Senkut did not immediately respond to a request for additional comment.
