Two things live at 350 E Street, and both matter equally. Rooms you can rent by the hour or the month — desks, a podcast studio, a media room, a workshop hall, a mailbox. And a team that helps you handle licensing, funding, permits, and marketing, at no cost, in English or Spanish.
Desks, podcast studio, media room, workshop hall, virtual office & mailbox — by the hour or by the month.

Talk With UsA team of local leaders and entrepreneurs committed to helping Sonoma County's small businesses succeed.

A local media and advertising executive and executive director of the Sonoma County Hispanic Chamber of Commerce, Hector spearheaded B-OSS — turning the vision of a coordinated small-business hub into a downtown home for Santa Rosa entrepreneurs.

Co-founder of B-OSS and owner of Soluna Outreach Solutions, a bilingual environmental consulting firm, Hugo helps connect underserved entrepreneurs with the resources and guidance they need to grow.

Owner of Santa Rosa–based Trejo Insurance Services, Antonio brings deep experience in commercial coverage and small-business risk, helping new entrepreneurs protect what they build.
Starting or growing a business shouldn't feel overwhelming. B-OSS cuts through the delays, confusion, and guesswork by giving you one place where things actually get done.

We strengthen existing services, not compete. Our system keeps everyone aligned.
Whether it's filings or loans, get immediate help from people who know business.
We keep track of your progress so you never have to start over or repeat your story.

“Choosing B-OSS means choosing clarity, structure, and a team committed to your long-term success.”
I had just earned my contractor's license when I was hired to remodel the B-OSS building. After the first week I felt overwhelmed and wanted to quit. Hector told me to take a week off and come back to finish the job. Like a lot of new business owners, I was scared of the unknown — but with that guidance I came back, and I finished what is now B-OSS.
I was selling food out of my backyard when I heard about the Mercado Rosa workshop. I attended, and with the guidance I received I earned my Cottage Food permit. Now I sell at farmers markets across the area — including Mercado Rosa itself.
B-OSS and its mission to support local entrepreneurs are making headlines across Sonoma County.
Fueled by up to $4.5 million from Sonoma County's public power agency, B-OSS is preparing to launch an ambitious initiative to streamline permitting for small business owners from minority and underserved communities — setting up shop in a newly purchased three-story building in downtown Santa Rosa.
