Bhubaneswar 16th Dec, 2025: Climate tech startup, Aurassure that delivers real-time, hyperlocal visibility into environmental risks for enterprises operating in increasingly volatile climates, has raised Rs 25 Crore in Pre-Series A led by Rainmatter by Zerodha and Unicorn India Ventures. The round also saw participation from Maithan Alloys Limited.

The funds raised will be strategically deployed towards global expansion accelerating Aurassure’s presence across the Global South with a focus on Latin America, South Asia, and Africa. This will include strengthening its Brazilian subsidiary, building regional teams, and scaling city-level deployments along with product development that will advance Aurassure’s Climate Intelligence Analytics Platform, expanding AI-driven predictive models, enhancing cloud analytics, and developing next-generation hyperlocal sensing systems. Additionally, with hardware innovation and manufacturing the company will advance sensor development for air quality, heat, rainfall, flooding and microclimate monitoring, with improved accuracy and durability and expanded calibration infrastructure, while optimizing manufacturing processes to support large-scale, cost-efficient deployments.

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, Aurassure addresses the growing gaps in environmental visibility caused by rising pollution, extreme heat, climate-induced flooding, and rapidly changing weather patterns.

Powered by a dense network of 2,000+ street-level sensors and proprietary AI-physics fusion models, Aurassure delivers ultra-high-resolution intelligence on air quality, heat stress, rainfall, water levels, wind dynamics, and urban flooding. This granular, ground-truth data enables enterprises and governments to anticipate climate disruptions before they occur, protect people and assets, and shift from reactive responses to proactive resilience.

Commenting on the fund raise, Akanksha Priyadarshini, Co-founder & CEO, Aurassure, says

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, Aurassure has also initiated early projects in Bangladesh, marking its entry into broader SEA markets. The Company has onboarded enterprise customers and partners across technology, insurance, healthcare, construction, and industrial sectors. The revenues have grown 150% Y-o-Y since its last round in 2023.

Bhaskar Majumdar, Managing Partner, Unicorn India Ventures says – The effects of climate change are a cause of concern not only in India but across the globe. India has been an active and influential player in the climate change ecosystem from the beginning and the Govt is also increasingly prioritising dealing with climate change. Aurassaure has tapped the market at a very right time as with its satellite integrated fusion and their proprietary AI physics model the company delivers high resolution air quality data. It is a unique proposition that integrates hyperlocal data sources and combines it with the satellite data building the AI ecosystem designed to work efficiently even in challenging climates. Their growing capabilities is the reason we continue to back Aurassure.”

Aurassure has also established new global partnerships, research collaborations, and strategic alliances with developmental organizations working on climate resilience in emerging markets. The company 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. The Company has also achieved key global product certifications, strengthening compliance, interoperability, and readiness for cross-border deployments.

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 company 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. The focus will be on deepening presence in high-risk urban regions, strengthening AI capabilities, and forming strategic partnerships to support climate resilience at city and enterprise scale. The company’s goal is to enable real-time climate awareness in 1,000 cities in the next 3 years across the Global South.

Commenting on the investment, Abhinav Singh Negi, Investments Team, Rainmatter says “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.”

Aurassure has recently launched two major products: the Climate Intelligence Analytics Platform (Aurassure Insights – AI Platform) and Avani, a personalized AI bot that answers climate-related questions for any location. It has also secured multiple large-scale deployments, and significantly strengthened its climate-risk datasets through ultra-high-resolution ground intelligence.

ValueBridge Capital (a Merisis Group Co.) acted as the banking partner and advisors to this fundraise for Aurassure, where they supported in unlocking tremendous value
