Eugenia Kuyda has spent over a decade building at the frontier of AI consumer products. First by founding Replika in 2014, hitting 30M users in conversational AI before ChatGPT even existed. Now, building Wabi: giving everyone the ability to build personal software. In this episode, she breaks down why she’s repeatedly chosen the solo founder path, why “co-founders by pressure” create long-term damage, and what it actually takes to keep going when things get brutally hard.
This is a conversation about conviction, authorship, loneliness, team-building, and the emotional reality of leading through uncertainty. Eugenia shares the difference between being truly solo vs. being isolated, why she treats founding as a team sport anyway, and how she thinks about hiring high-agency people who can operate like owners.
