BURST.USA, Inc.

Who owns Burst Oral Care? Burst is a private company, legally BURST.USA, Inc., owned by founders Hamish Khayat and Brittany Stewart along with investors Volition Capital and Goldman Sachs' GS Growth.

Where is Burst based? Venice, California, in the Los Angeles area.

How does the Burst ambassador program work? Dental hygienists and dentists join as ambassadors, recommend and sell Burst products to patients, and earn commissions. The network has exceeded 25,000 professionals.

Is Burst publicly traded? No. The company is venture-backed and private, last raising a Series C led by GS Growth in May 2020.

London-born entrepreneur Hamish Khayat designed his first toothbrush concept at 19, frustrated by the gap between cheap manual brushes and expensive electrics. He partnered with fellow entrepreneur Brittany Stewart in 2017 to launch Burst as a direct-to-consumer subscription company from California.

The brush reached 80,000 subscribers within a year, carried by the ambassador program that recruited dental hygienists to demonstrate and sell it. Volition Capital invested in 2018 as the ambassador network passed 9,000 members. In May 2020, Goldman Sachs' growth equity platform GS Growth led a Series C round, bringing disclosed funding to roughly $40 million.

Burst expanded through the early 2020s into a broader oral care range while keeping the sonic brush as flagship. It now competes with quip for DTC subscribers and with Oral-B and Philips Sonicare for sonic-technology credibility, leaning on professional endorsement as its main proof point.

Burst markets cruelty-free positioning and promotes its brush-head subscription as less wasteful than disposable brushing. It holds no major third-party sustainability certifications.
