Boson Whitewater, a water recycling startup, and TruNativ, a nutrition-focused D2C brand, have each raised Rs 10 crore in equity funding from Rainmatter, an early-stage venture firm supported by Zerodha.
Boson Whitewater specializes in converting excess sewage treatment plant (STP) water into potable water, addressing water scarcity issues in major cities like Bengaluru. On the other hand, TruNativ offers nutritional products such as Everyday Protein, Everyday Fibre, and Everyday Sweetener through its website and various e-commerce platforms.
Rainmatter has been actively investing in startups across fintech, clean energy, climate tech, and healthtech sectors. In the past two months, it has invested Rs 30 crore in several companies, including follow-on rounds in health-focused startup Devil’s Circuit, climate tech company GreenWorms, and fintech firm Actlogica.
According to Dinesh Pai, head of Rainmatter, the firm has invested around Rs 650 crore in a diverse range of startups since 2016. Of the Rs 1,000 crore committed by Zerodha co-founder and CEO Nithin Kamath last year, approximately Rs 150 crore has been deployed so far. Rainmatter also operates a not-for-profit entity named Rainmatter Foundation.
Rainmatter recently participated in the $6.5 million funding round of space tech startup GalaxEye, investing a total of Rs 5 crore across initial and follow-up rounds. The firm sees potential in geospatial data for addressing climate-related challenges such as early warning systems for natural disasters and unpredictable weather conditions, as well as applications in defense and agriculture.
Based in Bengaluru, Rainmatter has invested in around 100 companies, covering various sectors including 31 in fintech, 28 in climate tech, and 21 in health and nutrition. Pai emphasized that the firm provides patient capital without a specific exit timeline, aiming to support startups focused on building sustainable, long-term businesses for India and beyond.
