Today marks Uncork Capital's 21st 🎂 That would usually be reason enough to celebrate but I'm also delighted to announce that we've raised $300M in new funds to back the founders building the next generation of category-defining companies 🚀

So excited to bring the band back together! Thirteen years ago, we backed @jcjohnson and @yvesbehar when they built the August Smart Lock. A few months ago, @uncorkcap co-led the seed round for @thedomahome — a much bigger, bolder vision that we’re thrilled to share today: home

AI has changed the game for marketers, and generally not for the best - SEO and traditional outbound just don't work any more. However, Mutiny's new 𝗔𝗜 𝗳𝗼𝗿 𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗚𝗧𝗠 is a marketer's best friend. Already companies like Uber, GitLab, Twilio, and LaunchDarkly
