Mesmer
Mesmer is an AI 'chief of staff' for engineering organizations that watches the work itself - code, specs, designs and meetings - to give founders and CTOs a live picture of what is shipping, what is stalling and where the friction is, without pulling teams into more status meetings. Founded in 2025 by three repeat founders out of Origin Financial and Glio, the Y Combinator-backed company pitches itself as 'Cursor for CTOs' and says it has reviewed 70M+ lines of code for customers with a combined valuation north of $3B.
