Proof Lab

Our Very First Cafe, Located In The Heart of Marin’s Surf & Cycling Scene

Equator Coffees at Proof Lab is where our journey into retail began. Opened in 2013, this location was our very first cafe and remains a gathering place for coffee lovers, surfers, skaters, and outdoor adventurers alike.

Located on the Proof Lab campus in Tamalpais Valley Junction, this cafe is a gateway to adventure—just a short drive from Stinson Beach, Muir Beach, and the trailheads of Mount Tamalpais.

“When it opened in 2013, Proof Lab launched the second generation of Equator. It was the next phase of something we take a lot of pride in: introducing a new generation of coffee drinkers to who we are, to our years of expertise in sustainably sourcing, roasting, and serving incredible specialty coffees.”
— Helen Russell, Co-founder & Executive Chair of Equator Coffees
