About Mainframe

At Mainframe, our mission is to revolutionize the way people interact with computers through intuitive, seamless tools that enhance productivity. Our first product, Cobot, helps teams automate busywork and orchestrate agents to get more done—faster. It’s designed to feel like a teammate, not a tool. We believe the future of work won’t be app-based—it’ll be agent-based.

Founded in 2024, we’ve raised over $6.75m from top venture capitalists, founders, and product leaders at startups like Notion, Vercel, Adobe, Stripe, and OpenAI.

Why join us?

We’re building the next era of computing—and we’re just getting started. Join us if you want to shape how humans and AI work together.

Working at Mainframe

Our principles

• Ship early and often → We believe in velocity over perfection. Iteration is how we learn.
• Embrace ambiguity → We’re building something new. That means taking initiative without waiting for perfect clarity.
• Prioritize the user experience → Great UX is invisible. We obsess over clarity, speed, and delight in every interaction.
