Zerodha's Rainmatter, Unicorn India Ventures, invests Rs 25 crore in climatetech startup Aurassure

Aurassure, a climatetech startup that delivers real-time, hyperlocal visibility into environmental risks for enterprises operating in increasingly volatile climates, has raised Rs 25 crore in a pre-Series A funding round led by Rainmatter by Zerodha and Unicorn India Ventures.

The round also saw participation from Maithan Alloys Limited.

Founded in 2022 by serial entrepreneur Akanksha Priyadarshini, Aurassure has built a vertically integrated climate intelligence stack that transforms raw environmental signals into early warnings, risk indices, and operational insights.

While sensor-driven climate monitoring is still nascent globally, the startup addresses the growing gaps in environmental visibility caused by rising pollution, extreme heat, climate-induced flooding, and rapidly changing weather patterns.

Aurassure operates a network of over 2,000 street-level sensors and uses a combination of data models to generate information on air quality, temperature stress, rainfall, water levels, wind patterns, and flooding conditions. The data is intended to support monitoring and planning efforts by enterprises and public-sector organizations.

The startup plans to use the funding to expand its operations in regions including Latin America, South Asia, and Africa. This includes strengthening its presence in Brazil, building regional teams, scaling city-level deployments, and continuing development of its climate analytics platform, predictive models, cloud-based analytics, and sensing systems.

It also plans to continue work on hardware development and manufacturing, including sensors for air quality, heat, rainfall, flooding, and microclimate monitoring. These efforts are aimed at improving measurement accuracy and durability, expanding calibration capabilities, and optimizing manufacturing processes to support larger-scale deployments.

Akanksha Priyadarshini, who is also the CEO of Aurassure, said, “Enterprises today need climate intelligence that is immediate, accurate, and hyperlocal. Aurassure brings that capability to the ground by helping organizations reduce risk, protect people, and operate with confidence in an increasingly unpredictable climate. What was earlier a ‘nice to have’, has now become an absolute necessity. This fund raise enables us to accelerate that mission across the global South.”

In the last 12 months, Aurassure has expanded its network to over 2,000 sensor nodes with 99% uptime, scaled operations across 200+ cities in India and 100+ cities in Brazil. In addition to this, the startup has also initiated early projects in Bangladesh, marking its entry into broader SEA markets.

It has also established new global partnerships, research collaborations, and strategic alliances with developmental organizations working on climate resilience in emerging markets.

The startup has deepened engagements with international mapping and environmental platforms, advanced academic institutions, and public-interest research groups to improve the scientific accuracy and application of its models.

Over the next 12 months, Aurassure plans to expand its climate intelligence deployments across India, Brazil, and key markets in Southeast Asia and the Middle East. The startup  will scale its sensor infrastructure footprint, onboard new enterprise customers across insurance, renewables, logistics, and construction and accelerate adoption of its Climate Intelligence Analytics Platform.

It aims to enable real-time climate awareness in 1,000 cities in the next 3 years across the Global South.

Abhinav Singh Negi, Investments Team, Rainmatter, said, “Climate change is here and we are beginning to feel the effects in our lives. Though the long term goal for humanity is to take mitigating measures, it seems global policy and executive alignment will take some time. In the meantime, we cannot afford to just react to the adverse effects of climate change, we need to take a more proactive approach. This is where we feel Aurassure can contribute to our resilience. We are hoping to play a small role in this by supporting them.”
