Janji, a Boston-based running apparel brand, and Oiselle, a Seattle-based women’s athletic apparel company, have entered into a collaborative partnership through a merger facilitated by Digsbury Ventures.

The brands will continue to operate as sole entities leveraging each other’s resources for growth, establishing an omnichannel footprint and reaching new markets.

Oiselle Founder Sally Bergesen will step into an advisory role, while long-time Oiselle President Atsuko Tamura will continue to lead the brand.

Janji’s Co-founders, Mike Burnstein and Dave Spandorfer will stay in their roles at the company, while Matt McCalpin was named managing director of partnerships supporting operations across both brands.

Rooted in running, Janji and Oiselle will focus on delivering performance apparel for runners, expanding their presence to reach more runners globally.

“By coming together, both brands can grow their communities, lean in on their strengths and continue their unique mission—to support runners and make the world a better place through running,” said Spandorfer. “This merger allows us to think incredibly long-term and support our communities, the Volée and the Collective, even more.”

Oiselle and Janji will maintain their separate headquarters in Seattle and Boston, and both brands are releasing new collections for spring/summer 2023.
