Aclima builds a combined hardware and software system that measures air pollution and greenhouse gases at high spatial resolution using its own patented sensors and a network of roving and stationary devices. The company integrates those inputs, compares them to nearby EPA monitors for quality control, and provides a data interface that highlights areas of concern by pollutant, toxin, GHG, or source. Its professional analytics software translates billions of scientific measurements into environmental intelligence for governments, companies, and communities. Aclima emphasizes a science-driven approach and public-health outcomes, and it cites work aimed at reducing emissions and delivering cleaner air. The company has received recognition including TIME100 Most Influential Companies (2023) and inclusion on the GovTech 100 (2023 and 2024), and it recently announced a historic deal with the California Air Resources Board. CEO Davida Herzl said the company will use capital to continue focusing on innovations and scaling revenue. Aclima develops hyperlocal measurement platforms that capture greenhouse gases and regulated air pollutants through mobile and stationary sensor networks. Its technology combines fleets of roving vehicles with stationary sensors and a backend analytics platform to map emissions at neighborhood scale. The company offers an enterprise professional software product for regulators and businesses, a free public tool, and a third revenue stream via partnerships with companies like Google that attach Aclima sensors to mapping vehicles. Aclima’s technologies are deployed across California, with major customers including municipalities in the Bay Area and San Diego, and its data has been used for community intervention plans such as in West Oakland. The startup positions its data at the intersection of climate, public health and environmental justice, helping governments and industry benchmark and prioritize emission reductions. Aclima raised $40 million in new funding to accelerate growth and expand capacity to support new and existing customers. The company was founded by Davida Herzl and is about a decade old. Aclima builds internet-connected air quality sensors and a software platform to generate hyperlocal pollution maps and analytics. The company partners with vehicle fleets (including work with Google StreetView) to deploy mobile sensors and create dense measurement networks. It monetizes interpreted data through a SaaS platform and often finances or part-finances sensor deployments for fleet partners. Aclima has demonstrated its technology across California—mapping the Bay Area, Central Valley and Los Angeles—and its data has supported scientific studies and local policy, including links to cardiovascular risk and school filtration decisions. The company reports its platform provides up to 100,000x greater spatial resolution at a 100–1,000x cost reduction and is investing in R&D to add pollutants (CO2, methane, particulate matter, black carbon) and future capabilities such as VOC speciation and smaller, lower-cost sensors. The new funding will be used to grow headcount, secure more fleet partnerships, expand pollutant coverage and pursue broader geographic (including global) expansion.
