We are pleased to announce that Cornerstone Partners has led a seed round into boxing inspired fitness studio and digital content platform, Boxx.

Boxx was founded in 2016 by Anna Samuels, after discovering a personal passion for boxing and a desire to create a world class online workout that was compatible with the busy and ever changing schedules of ordinary people.

Community driven from the start, Boxx offers flexible at home and studio workouts across boxing, HIIT, Strength and Yoga and serves every type of customer, regardless of fitness levels, age, body shape or size. More than 2 million minutes of Boxx’s workouts have been completed online to date and the workout app has reached more than 200k downloads.

The investment will drive forward plans to accelerate Boxx’s content strategy, hire additional staff and further develop its offering with the launch of a connected fitness product.

Anna Samuels, Founder of Boxx commented:

“At Boxx, accessibility is one of the core values that underpin our brand. From the initial conversation with Cornerstone, not only did they understand our vision but their commitment to back underrepresented founders and their shared values was something that really stood out for us.

In addition to Cornerstone, we have a number of other angels participating in this round, who bring value in a multiple of ways. Together we believe this will help us deliver on our mission to create a connected fitness product that makes boxing inspired fitness accessible to all.

We are extremely excited to see what the future holds.”

Rodney Appiah, Chair of Cornerstone Partners commented:

“We are delighted to be working with Anna, Bryan, Tyrone and the wider team to support Boxx’s growth plans. Their mission to make boxing accessible to everyone with their content led strategy and launch of innovative products and services provides a unique opportunity to disrupt the popular UK boxing industry. We look forward to supporting Boxx over the coming years and working with the other angel investors who participated in this round.”
