Business Insider 2025-05-23T09:00:02Z Impact Link Log in Founded by former Uber managers, the startup builds a general-purpose AI teammate for the workplace. Business Insider got an exclusive look at the pitch deck Coworker used to raise its seed round. Your newest work colleague might not be joining you at the water cooler or at the team's next happy hour: AI agents are infiltrating the workplace, and one startup building those — aptly named Coworker — just cleared a big funding round to put "AI teammates" to work. Jeff Huber, managing director at Triatomic Capital, led Coworker's $13 million seed funding round, which was announced on Tuesday. Ramtin Naimi of Abstract Ventures, Mallun Yen of Operator Collective, Tim Young of Eniac Ventures , and Clark Golestani, Ken Hausman, and Jack Greenfield of K2 Access Fund also participated in the raise. Based in San Francisco, Coworker bills itself as a general-purpose AI teammate that can research, plan, and execute high-level work just like an experienced colleague can. The startup said its technology, which about 25 companies have been beta testing since late 2024, has been used across engineering, product management, sales marketing, and operations functions. For example, a Coworker can act as an engineering teammate to  write code , create and review pull requests, and automate release notes, keeping human developers focused on shipping new features. It can also act as a sales teammate, analyzing sales calls and generating proposals and follow-up emails. Coworker uses its own products at work, which gives the startup a leg up in shipping new features and developing the technology, said CEO and cofounder Alex Calder. For example, Coworker's agents do work like drafting product requirement documents based on customer feedback, creating tickets, writing code, and turning that code into sales talking points, he said. "In the last six months, we've seen our internal team going from 'AI is good at giving me information' to 'AI is good at using that information to do work for me'," Calder told Business Insider. "That's only possible when you give AI really rich context on your company, your goals, and how you do work." Calder and his cofounder, Coworker chief product officer Bradford Church, are former Uber managers who led the transportation company's shared rides team. AI agents are generating strong interest from VCs, and there's high demand, especially for agents that take over rote workplace tasks and free up human employees to focus on more creative and high-impact work. In May, ThriveAI , which builds AI agents that act as junior software engineers, announced a $1.2 million pre-seed round, and AI coding agent startup StackAI announced it landed $16 million. Another general-purpose AI workplace agent, Artisan , announced in April it raised $25 million. Calder acknowledged that the AI agent market is getting crowded. When it came to getting VCs excited, focusing on customers helped Coworker close the round, he said. "There are so many jaw-dropping AI demos these days that VCs are totally desensitized to them," he said. "What they really care about is how customers are actually using the product and whether it can solve real problems at scale. I think what worked in our favor is that we were able to show the real impact Coworker is having inside large companies during our fundraise." Coworker previously raised $3.5 million in pre-seed funding from Soma Capital, Focal VC, Mischief, and Karman Ventures.
