What Aclima does
Aclima is a San Francisco-headquartered climate technology company that operates an integrated hardware-software platform for hyperlocal measurement and analysis of air pollution and greenhouse gases. The platform combines a fleet of roving, sensor-equipped vehicles with a network of stationary monitors to collect continuous measurements of more than ten pollutants, including PM2.5, ozone, nitrogen dioxide, carbon monoxide, methane, carbon dioxide, black carbon, benzene, and VOCs, at block-by-block resolution claimed to be up to 100,000 times greater than traditional monitoring. Data is processed through machine learning-enabled analytics and delivered to commercial and government customers via Aclima Pro, a professional software subscription, while a free consumer application called air.health provides address-level public access.
The company's core products include the Mobile Air Quality Sensor Network, the Stationary Sensor Network, the Aclima Pro analytics software, and the air.health consumer app; Aclima also operates the Groundtruth Fund, an impact initiative providing grants to community-based organizations in underserved areas where monitoring is deployed. Its go-to-market is primarily enterprise field sales targeting state, county, and city government agencies, with a secondary focus on research institutions and environmental justice communities. Revenue is generated through SaaS subscriptions, multi-year managed-services contracts, and contract financing arrangements with state agencies, including the California Air Resources Board (CARB), the New York State Department of Environmental Conservation, the Bay Area Air Quality Management District, and San Diego County. Aclima is a Delaware-incorporated Public Benefit Corporation, founded in 2008 by Davida Herzl, and has raised approximately $64-77 million in venture and grant funding across a Series A (2018) and Series B (2020/2025 depending on source), supplemented by $13 million in contract financing and grants from the Exelon Foundation, NYSERDA, and others.

Product offeringCore offering
Aclima operates an integrated hardware-software environmental intelligence platform that combines a mobile fleet of sensor-equipped vehicles and stationary sensor networks to collect hyperlocal air quality and greenhouse gas measurements at block-by-block resolution. The platform measures 10+ pollutants simultaneously (PM2.5, ozone, nitrogen dioxide, carbon monoxide, methane, carbon dioxide, black carbon, benzene, VOCs), processes billions of data points through cloud-based analytics, and delivers insights via the Aclima Pro software subscription. Customers include government environmental agencies, enterprises, and communities that use the data to identify pollution hotspots, support regulatory compliance, and drive climate and public health action.
Product overview
Aclima offers an integrated hardware-software platform for air quality and greenhouse gas measurement and analysis. The platform consists of two complementary components: a sensor network (combining mobile roving vehicles and stationary monitors) that collects hyperlocal measurements at block-by-block resolution, and Aclima Pro, the professional analytics software subscription that translates billions of measurements into environmental intelligence. Aclima Pro serves commercial and government customers, while the companion air.health application provides free public access to address-level air quality insights. The Groundtruth Fund is a separate impact initiative providing grants to community organizations. The platform measures and analyzes air pollution, greenhouse gases, and toxics simultaneously, providing the broadest set of pollutant measurements on the market.

Products and services
- Aclima Pro Professional SaaS analytics platform that translates billions of air quality and greenhouse gas measurements from Aclima's sensor network into environmental intelligence. Empowers users to analyze and visualize hyperlocal block-by-block data, combine it with hundreds of contextual layers, identify pollution hotspots, and drive climate and public health action. Subscribed to by the Bay Area Air Quality Management District and used by enterprise and research customers.
- Mobile Air Quality Sensor Network (Managed Service) Managed service consisting of a fleet of sensor-equipped low-emission vehicles that drive every public street to collect continuous hyperlocal measurements of PM2.5, ozone, nitrogen dioxide, carbon monoxide, carbon dioxide, methane, black carbon, benzene, and VOCs. Data is streamed to Aclima's cloud-based analytics platform. The service is delivered under multi-year government and enterprise contracts and includes intelligent routing software for scientifically robust data collection.
- Stationary Sensor Network Fixed-location air quality monitors that provide continuous real-time measurements at specific locations, complementing the mobile monitoring fleet by tracking changes over time at stationary points and supplying 24/7 air quality data to communities and customers.
- air.health Free public-facing web and mobile application that maps address-level air and climate insights, allowing residents to search by address and view pollutant levels at the block level with online maps and explanations of health impacts. Available on iOS (App Store id 1462820376) and Android (Google Play id air.health).
Quantifiable outcome
- Pollution can vary by up to 8x (800%) from one block to another, demonstrating the need for hyperlocal measurement

Aclima competitors and assessment
Company assessmentEmerging players
- AirGradient: Open-source, low-cost air quality monitor manufacturer popular for community and citizen-science deployments. Represents the low-cost alternative that could pressure Aclima's pricing in cost-sensitive municipal and community RFPs.
- Kunak Technologies: Spanish environmental sensor manufacturer providing air quality and emissions monitoring stations for cities and industry. Comparable hyperlocal and reference-grade monitoring offering, primarily serving European and Latin American municipalities.
Direct peers
- IQAir: Swiss-based air quality monitoring company producing consumer, professional, and government-grade air quality sensors and air quality information platforms. Directly comparable to Aclima in measurement breadth and government/enterprise customer base, though more consumer-skewed.
- Aerodyne Research: Specialized atmospheric and air quality measurement instrumentation firm with research-grade sensors for trace gases and aerosols. Already partners with Aclima on California's SMMI Targeted Area Studies and competes in high-precision ambient monitoring.
- BreezoMeter: Air quality data and analytics platform providing hyperlocal air quality insights via APIs and SaaS to enterprises, smart cities, and consumer applications. Highly comparable data-platform business model to Aclima Pro.
- Clarity Movement: Low-cost air quality sensor network operator serving governments and communities in emerging markets (notably India and East Africa). Comparable low-cost sensor + data SaaS model, though with different geographic focus.
- Plume Labs (AccuWeather): Air quality data and forecasting platform (acquired by AccuWeather) operating mobile sensing fleets and consumer-facing pollution forecasts. Closely comparable to Aclima's mobile-fleet + consumer-data approach, with global footprint.
Broad incumbents
- Honeywell: Diversified industrial conglomerate whose Sensing and Productivity Solutions unit includes indoor and outdoor air quality monitors. Competes with Aclima primarily in commercial/industrial IAQ and building sensor markets.
- Vaisala: Finnish incumbent providing professional environmental and industrial measurement instruments including weather, air quality, and road weather stations. Overlaps with Aclima in government ambient monitoring but spans a much broader portfolio of meteorology and industrial sensing.
- Thermo Fisher Scientific: Global analytical instruments and lab services giant whose environmental monitoring division provides regulatory-grade air quality instrumentation. Represents the established large-vendor incumbent Aclima competes against in EPA/state procurement.
