14.ai is an AI-native customer support company that operates as an AI-first support agency for startups and high-growth companies. Rather than selling a chatbot to bolt onto an existing team, 14.ai deploys autonomous AI agents that take over frontline customer support entirely, resolving conversations end-to-end while integrating with a company's tools and knowledge. Founded by married duo Marie Schneegans and Michael Fester, the Y Combinator-backed company has already replaced legacy customer support teams at many of the startups it works with. 14.ai raised a $3M seed round led by Y Combinator with participation from General Catalyst, Base Case Capital and SV Angel, alongside founders of Dropbox, Slack, Replit and Vercel, as it scales its AI-native support model.
