Mesmer

Mesmer offers an AI-powered chief of staff platform tailored for Chief Technology Officers and other technology leaders in high-growth companies. Founded in 2025 by the experienced team of João de Paula (CEO), Lucas Silva (CTO), and Sergio Oliveira Bergmann (VP of Engineering), the company emerged from the founders' direct experiences with coordination challenges at their previous ventures. The founding team are repeat entrepreneurs and CTOs who previously led product development at companies like Glio (S13) and Origin Financial, which scaled to an 8-figure ARR and a $400M valuation. Their collective 15+ years of experience in engineering and product leadership in fintech and digital banking informed the creation of Mesmer.

The company's core product acts as a 'Cursor for CTOs,' providing full visibility into an organization's product development without the need for constant meetings and status updates. Mesmer's AI agents connect to a company's existing tool stack—including GitHub, Slack, Figma, and Notion—to quietly observe work as it happens, analyzing code, designs, and meetings. This allows the platform to build a real-time, detailed picture of projects, delivering regular updates that highlight progress, shipped features, and potential bottlenecks. The primary goal is to help tech leaders identify risks early, keep teams focused on shipping products, and maintain the operational speed of a lean startup even as the organization scales. The business serves technology leaders at companies of various sizes, with clients like Webflow and Origin Financial already using the platform. After launching, Mesmer reported reaching six-figure annual recurring revenue (ARR) within its first week.
