Company profile
researched Sep 2026Aclymate is a Denver, Colorado-based climate technology company that combines carbon accounting software with expert guidance and done-for-you services. The platform supports a full sustainability lifecycle framed as plan, measure, manage, report, improve, and prove: defining program goals and responsibilities, calculating Scope 1, 2, and 3 emissions, tracking initiatives and data requests, preparing reporting outputs, identifying reduction opportunities, and supporting certifications, offsets, renewable energy certificates (RECs), and supporting evidence.
The offering is structured in three tiers. Aclymate Explorer is a free, AI-guided tool for estimating a company's carbon footprint, identifying data gaps, and collecting Scope 3 supplier data. Aclymate Navigator is the core paid platform covering carbon accounting, dashboards, reporting, supplier data, and customer requests. Aclymate One adds expert services including onboarding, data collection, carbon bookkeeping, reporting, and program guidance, delivered by carbon accountants, sustainability consultants, and program managers. Additional service lines cover supplier and Scope 3 data support, certification and claims support, sustainability program support, and offset and REC guidance.
Aclymate also operates its own Climate Certification Program with three levels — Climate Wise (starter), Climate Leader (mid, for companies setting and meeting yearly emissions reduction goals and offsetting the remainder), and Net Zero (highest) — alongside support for third-party certification readiness, customer sustainability questionnaires, supplier forms, RFP documentation, and evidence and certificate management.
Founding story
Aclymate was co-founded by Mike Smith, a former Navy pilot who serves as CEO, and William Loopesko, an engineer who serves as CTO and previously founded PuppTech. Loopesko built the Aclymate platform from the ground up, and Smith co-founded the company to make sustainability management accessible to companies without large internal teams.
Business model
B2B software-and-services model. Aclymate sells a tiered product line: Aclymate Explorer, a free carbon calculator and supplier data collection tool; Aclymate Navigator, the core paid platform for carbon accounting, reporting, dashboards, supplier data, and program management; and Aclymate One, which bundles the platform with hands-on expert services such as onboarding, data collection, carbon bookkeeping, and reporting. Pricing covers Explorer, Navigator, Aclymate One, add-ons, and custom programs. Third-party profiles characterize the business model as B2B with subscription SaaS, services and consulting, freemium, and marketplace commission components.
Revenue comes from subscriptions to the Navigator platform and from Aclymate One service engagements, with a free Explorer tier serving as an entry point. Add-ons and custom programs are also priced, and the company supports sourcing of environmental commodities such as offsets and RECs. Third-party profiles additionally attribute services/consulting and marketplace commission revenue components.

▸Full profile — market position, technology, go-to-market, geography, history
Market position
Aclymate operates in the carbon accounting and sustainability reporting software market, focused on small, growing, and mid-market businesses rather than large enterprises, and is described as an affordable, easy-to-use option for teams without dedicated sustainability staff. Third-party sources list Watershed, Greenly, GreenPlaces, and CarbonSustain among comparable or competing carbon accounting platforms.
Aclymate positions itself between spreadsheets, software-only carbon accounting platforms, consultants, and offset marketplaces by pairing a platform with staffed services — carbon bookkeepers, sustainability consultants, and program managers — so that customers without internal sustainability headcount can have the work executed for them. It also operates its own tiered certification program (Climate Wise, Climate Leader, Net Zero), which provides customer-facing proof assets in addition to measurement and reporting outputs. Customer testimonials cite personalized service at lower cost than more expensive alternatives.
Technology
A connected platform for Scope 1, 2, and 3 carbon accounting, supplier and Scope 3 data collection, sustainability dashboards, initiative and task tracking, reporting outputs, and evidence and certificate management. The company describes an AI capability branded Scout that assists users while retaining human judgment and evidence review, an AI-guided free Explorer tool, and integrations and a shared data foundation across lifecycle modules. Its web stack is reported to include Webflow, Vercel, Segment, Zendesk, ActiveCampaign, Calendly, Visual Website Optimizer, and PayPal.
Go-to-market
Aclymate markets directly to growing and mid-market businesses through its website with free-to-paid conversion via the Explorer tool, demos, and consultations with sustainability experts. It uses industry-specific positioning (branded merchandise, specialty manufacturing, apparel and footwear, automotive and transportation, CPG/food and beverage, professional services, events and venues) and role-based messaging for executives, operations and finance, ESG/EHS/compliance, sustainability managers, and procurement leaders. Partnerships (for example with CNaught and Good Business Colorado), customer case studies, comparison content against competing carbon accounting platforms, press releases, and a podcast support demand generation. The marketing function is led by a chief marketing officer.
Growing and mid-sized businesses, generally from roughly 30 to 2,000 employees, that lack dedicated sustainability staff. Buyers include founders and executives at smaller companies; operations, EHS, ESG, compliance, and finance teams at mid-sized companies; and heads or directors of sustainability at larger mid-market firms. Named industries include branded merchandise, specialty manufacturing, apparel and footwear, automotive and transportation, CPG/food and beverage, professional services, and events and venues.
