Rainmatter, backed by Zerodha, has invested roughly $3.5 million (approximately Rs 28 crore) into Fittr, a fitness startup situated in Pune. Prior to this, Fittr had garnered around $11 million from various investors such as Elysian Park, an American private investment firm, Peak XV's seed fund Surge, and other backers in 2021. With this latest funding, Fittr has accumulated a total of $17 million in equity funding since its inception in 2016.

Rainmatter has nurtured a network of roughly 18 startups operating within the health and wellness domain through its investments. These include Aroleap, Devils Circuit, Ultrahuman, Trunativ, and Humanedge. Fittr founder Jitendra Chouksey expressed that securing funding from Rainmatter would grant the startup access to Zerodha's entire health and wellness startup ecosystem. Chouksey emphasized the potential collaboration between Fittr and other health and wellness startups supported by Rainmatter to effectively promote individuals' health and fitness.

In terms of Fittr's financial performance, the startup has recently achieved profitability on a quarterly basis and sustains an annual recurring revenue run rate of Rs 120 crore. Chouksey indicated that once the company consistently attains year-on-year profits, it might consider the prospect of going public. However, the current primary focus remains on establishing a sustainable and profitable business model. Fittr boasts roughly 250,000 active users monthly and has surpassed five million app downloads. The platform offers online fitness and nutrition coaching services in addition to personalized training sessions.
