Climatiq, a startup that’s built an AI-enabled platform for companies to collect and automate their carbon emission data, has secured a $11.6 million Series A led by Alstin Capital.
The Berlin startup’s tool analyzes everything from supply chain data to purchase orders to calculate a company’s scope 3 emissions, which measure its indirect carbon footprint.
“If you’re building any other kind of software, there are existing APIs — but not for carbon emissions. So we’ve built an infrastructure for carbon tooling,” Climatiq’s cofounder and CEO, Hessam Lavi, told Business Insider in an interview.
Scope 3 emissions, which typically represent around 90% of a company’s carbon footprint, are often hard to reliably measure because they are collated from a fragmented set of data points. Climatiq’s AI platform automates the collection of this data from various sources, such as NGOs, the Intergovernmental Panel on Climate Change, and universities.
These carbon metrics can then be integrated into companies’ emissions reports.
“There’s going to be a need for a trusted source on carbon data. If everyone is reporting data, how do you have confidence in their methodology? That got us interested in building an infrastructure platform for carbon accounting,” Lavi said.
Some companies in the US and Europe are required to calculate their emissions data to ensure they’re complying with ESG regulations. Climatiq charges clients, which include the likes of Celonis and Siemens, based on their usage.
Lavi gave the example of feeding the transport records of a freight company into its platform. “We process it, and provide a carbon estimate to our partners — and charge for that API request,” Lavi added.
President Donald Trump’s second term has triggered a wave of backlash against ESG incentives, which has had a knock-on effect on climate startups. In Q1, VC funding into climate tech dried up 50% year-on-year, per PitchBook data, and high-profile climate startups such as Climeworks have announced layoffs in 2025.
Amid this environment, Lavi found the fundraising process considerably more difficult than Climatiq’s $5.8 million seed in 2022.
“It was much tougher than I expected. Compared to our pre-seed and seed, it’s definitely a different chaos,” he told BI, adding that the startup spoke to around 70 VCs for this funding round.
The Series A was led by Munich-based venture capital firm Alstin Capital, with backing from Singular and Cherry Ventures.
With the cash injection, Climatiq plans to grow its engineering head count and develop its AI product.
