Mainframe, a company designing intelligent and beautiful generative productivity software, has announced an oversubscribed $5.5 million seed funding round. The funding round was co-led by Peter Boyce II of Stellation and Lachy Groom, with participation from Alana Goyal, Akshay Kothari (co-founder of Notion), Weekend Fund, and others. This funding brings the company’s total to $6.75 million and highlights investor confidence in Mainframe’s vision to build tools that elevate human productivity and reimagine how humans and computers interact.
Mainframe co-founder Jordan Singer is known for his design and product innovation work, bringing a proven track record that includes founding Diagram (acquired by Figma) and driving impactful user experiences during his tenure at Cash App.
Singer’s background in building tools that combine design with advanced functionality inspires Mainframe product philosophy: prioritize user experience, simplicity and elegance. He is joined by a distributed team of engineers and product innovators, with talent spanning San Francisco, New York, Canada, and Europe. And the company’s remote-first approach both echoes the innovative spirit of San Francisco – utilizing technology to work more efficiently – and embraces the flexibility and inclusivity of having a global team. The combined wealth of industry experience underscores Mainframe’s ability to lead the fast-evolving AI software space.
Mainframe is advancing the development of generative productivity software that transforms digital workflows. The company’s debut product, Cobot, is a generative AI assistant designed to anticipate user needs and streamline daily tasks, launching in Q1 of 2025. Unlike traditional tools that passively wait for input, Cobot actively collaborates with users, leveraging advanced AI to predict actions and reduce repetitive tasks, freeing users to focus on more meaningful work.
The funding will enable Mainframe to expand its team, accelerate product development, and bring innovative solutions to market. Mainframe is actively hiring across engineering and product roles to build the foundation for future breakthroughs in human-computer interaction.
KEY QUOTES:
“At Mainframe, we’re imagining a future where AI is the default, software generates itself and agents are the new apps. Large language models have transformed the perceived capabilities of computers. We’re building what it looks and feels like to operate in a new environment where the bicycle for the mind has an engine.”
- Jordan Singer, co-founder and CEO of Mainframe
“Mainframe is redefining what it means to interact with technology by creating tools that feel less like software and more like a trusted collaborator. The company’s vision for intelligent, proactive AI solutions like Cobot addresses a significant gap in the productivity space, and we believe they are poised to set a new standard for how people work with computers.”
- Co-lead investor Lachy Groom
“It’s exciting to see a number of new AI products on the market, but enduring success will likely belong to tools that do more than just perform tasks quickly, focusing instead on genuine user-friendliness and intuitive design. The team at Mainframe is well-positioned to deliver these platforms having directly developed some of the most widely used consumer and enterprise digital products. We’re eager to witness their long-range vision take shape.”
- Peter Boyce II, founder and managing partner at Stellation Capital
