Welcome to Seattle Flow: Your front door to Seattle's startup scene

Seattle Flow is not just a product. It's a founder-led movement to bring more founders into the fold and help them succeed on the global stage.

Today, I’m happy to announce Seattle Flow. It’s the one place for founders, investors, and people working with startups to discover, understand, and participate in what’s happening in the Seattle region’s startup scene.

Seattle Flow is not just a product. It’s a founder-led movement to bring more founders into the fold and help them succeed on the global stage. Seattle’s enormous capacity for innovation has not been completely unlocked. The only thing holding us back is ourselves. Read the [Seattle Flow Manifesto for Founders: Building Out Loud.

We believe that Seattle can have many times more founders and startups than we have today, and that our region will build the defining tech products of the next decades. We have all the right ingredients to make this a reality.

Seattle Flow means putting us in the zone: building, shipping, and talking about our products and our people.

We help you discover the founders, investors, and organizations that can help you in your journey. We find the news, podcasts, and videos about our founders and startups, amplify them, and send you straight to the source. And we help the ecosystem connect by finding the right events for founders and builders, and the jobs at the region’s startups.

What can you do today?

First, create an account on Seattle Flow and claim your profile. Whether you’re a founder, an investor, or someone working with startups, it’s how you’re counted.

Second, think of the people you know who are building something. Maybe a friend just told you about the product they’re working on nights and weekends, or a colleague is wondering how to turn a side project into a startup. Send them to Seattle Flow and be loud about their launches and their wins.

Third, tell your story (or other founders’ stories). If you’re writing, or you’ve been thinking about starting a podcast or YouTube channel about startups and founders in the region, this is the time. Tag us or send us your link and we’ll make it louder and help you find an audience.

Seattle Flow is also a startup, and we are building and shipping fast. Tell us what’s working, what isn’t, and what you want to see.

Welcome to the fold.

-Marcelo, founder
