Borrowed Brains is a peer advisory series for founders who are deep in the work of running and growing a service business, brought to you by Christine Lavin, Lavin Advisory Group, in partnership with HAYVN. Each session brings together a small group of business owners for a facilitated conversation on a single, broad-based operational theme. No presentations. No panels. Just a room full of people who are building something, talking through what's actually hard about it. HAYVN Member discount with code in portal.
