MSIV Hosts 5th Annual Fall Party

On October 15th, MSIV wrapped up our 2025 community events calendar with our 5th Annual Fall Party. Nearly 200 members of the North Bay startup community gathered at Brewster's Beer Garden in Petaluma for an afternoon of networking and camaraderie. Mother Nature cooperated beautifully; the morning rain cleared just in time to enjoy the fall foliage and live music from Mill Valley-based musician Matt Bolton.

This well-loved Fall Party tradition welcomes new founders and mentors into the community while reconnecting familiar faces and strengthening the collaborative network that drives our region's entrepreneurial growth.

The celebration marked a year of momentum in growing the local startup ecosystem across Marin and Sonoma. Leading up to this milestone, MSIV hosted over 20 community events throughout the year—each focused on supporting local startup founders, including our Mentorship Mixer and North Bay NEXT.

Thank you to our Founding Sponsor, Redwood Credit Union, Platinum Sponsors Bank of America and the Francoise O. Lepage Center for Global Innovation at Dominican University of California, and Gold Sponsors Cerity Partners, North River Company, and Acrisure for their generous support in making MSIV’s 2025 community events possible.
