Partnerships Built on Shared Values

Our founding partners are some of the most respected names in specialty coffee. They've spent years, often decades, building long-standing relationships with farmers and producers while continually refining their craft, all in pursuit of exceptional coffee.

They represent a wide range of roasting styles, philosophies, and communities across the United States, but they share a common commitment to quality, transparency, thoughtful sourcing, and responsible business practices. They're not simply featured on Siip; they're helping shape what we're building together.

Discover Coffees From Our Founding Partners

Every founding partner's full lineup is available to explore in the Siip app. As you rate more coffees and your taste profile evolves, you'll see which coffees from each roaster are your strongest matches.

When you subscribe, each month you'll receive coffees selected from the roaster whose offerings best fit your taste, making it easy to discover exceptional coffees from across the country.

Every bag represents more than a great cup of coffee. It's an opportunity to discover something new while supporting a coffee ecosystem built on long-term relationships, shared values, and trust—from seed to cup.

Frequently Asked Questions

Siip's founding roaster partners are true collaborators in building the Siip ecosystem from the ground up. These are roasters who have spent years — often decades — shaping specialty coffee: championing exceptional producers, refining their craft, and helping consumers discover what great coffee can be. As founding partners, they're not just participating, they're helping define what Siip becomes.

Siip learns from every coffee you rate. When you scan a coffee bag in the app and rate it, Siip maps your preferences across origins, processing methods, roast levels, and flavor profiles. It builds a personal taste profile that helps you understand what you love and why. When you subscribe, Siip uses that profile to match you with coffees from its roster of partner roasters. The roaster whose coffee best fits your palate is the one that gets shipped. The more you rate, the better your matches become.

With the current launch offer (20% off your first 2 months), Siip subscriptions start at $14.40/bag for two bags per month with free shipping. Plans range from Classic ($14.40/bag, normally $18) to Craft ($19.20/bag, normally $24, most popular) to Reserve ($24/bag, normally $30). After the first 2 months plans renew at the standard price. Cancel anytime from the app.

Yes — when you subscribe, Siip matches your taste profile against every available coffee from our founding partners. If a specific roaster is consistently your highest match, that's the roaster whose coffees you'll receive. The more you rate coffees in the app, the more accurate those matches become.

Founding partners are roasters with deep, established producer relationships and a track record of excellence in specialty coffee. Many have been in business for decades, have won industry awards, or have helped shape the modern specialty coffee scene. We work with each one to bring their full lineup to Siip drinkers across the country.
