Mainstay Venture Partners acquires small businesses across Northern California. We focus on established companies in and around San Francisco, San Jose, Sacramento, and Tahoe that provide essential products or services and have strong reputations in their communities.

Our goal is simple: to preserve what already works while supporting long-term growth. Many small businesses are built through decades of hard work, and when owners decide to retire or step away, we provide a thoughtful transition that keeps those businesses operating and serving their customers. We take a long-term approach to ownership. We operate the businesses we acquire responsibly and continue the legacies the founders created.

We work directly with business owners, brokers, and advisors to ensure smooth, straightforward transactions. Our process is transparent, flexible, and designed to meet the needs of owners who care about what happens to their business after they step away.
