About Us

These moments are meaningful.

We want to help make your party exceptional so you can focus on enjoying time with your guests, not managing every detail.

Genuine

We want our customers to feel supported and informed.

We show up when we say we will, and we keep you informed every step of the way.

Reliable

Curated

Too many options can be overwhelming.

We’re a small operation. We only carry items we would use ourselves, and limit variations to avoid decision fatigue.

We love serving the Bay Area.

Having been raised locally, we’ve held and attended a lot of great parties here. We hope we can help you do the same.

Local

Matt and Kate when they were little.

PartyBiz is run by Kate and Matt, siblings who share a passion for parties. Their enthusiasm stems from a large, close-knit family where celebrations are an important tradition.

Organizing birthdays and milestones has increasingly felt like a drag with a growing family and responsibilities. But does it really need to be? We want to bring you packaged party convenience and a level of service unparalleled.

Our family-biz goal is to make having parties that look good and feel effortless so that you’ll want to do it again and again. Leave the heavy lifting to us.
