What Climatebase does
Climatebase operates a vertically specialized climate career platform that connects mission-driven talent with employers working on climate solutions. The core product is a self-serve web-based jobs marketplace at Climatebase.org serving more than 1 million users annually, with a directory of 100,000+ monthly active climate professionals, embedded AI-powered candidate matching, an integrated applicant tracking system, direct messaging, and live virtual hiring events. Employers include climate tech startups (e.g., TeraWatt Infrastructure, Orenda, Planted, EcoG, Phase Biolabs), NGOs (e.g., Adamant, Terraformation), and ESG software firms (e.g., ACTUAL). The platform has facilitated 500,000+ matches and 10,000+ hires.
Climatebase monetizes through two primary streams. On the employer side, it sells job postings, AI-powered talent recommendations, Climatebase Weekly newsletter promotions to 150,000+ subscribers, Climatebase LIVE hiring event participation, and a Recruiting-as-a-Service offering. On the talent side, the Climatebase Fellowship is a 12-week cohort-based career accelerator priced at $1,990, with more than 50% of Fellows receiving need-based financial aid; the program has produced 3,200+ alumni from 15,000+ applicants across seven cohorts and feeds graduates into ongoing community membership.
Beyond the marketplace, Climatebase has built a multi-product brand spanning Climatebase Weekly (a thrice-weekly newsletter), the Climatebase Community platform (networking for Fellows and climate professionals), and the Climate Week Network. SF Climate Week 2026 is expected to draw 60,000+ attendees across 650+ events with 1,000+ speakers including Al Gore and SF Mayor Daniel Lurie, organized in partnership with over 1,000 organizations. Colorado Climate Week has launched as the second flagship, and the Climate Week Network encompasses 20+ global climate weeks. The company is privately held and founder-led by CEO Evan Hynes, COO Jesse Hynes, and CTO Justin Hardin, with one disclosed early funding event including APA Venture Partners and Third Sphere.

Climatebase competitors and assessment
Company assessmentBroad incumbents
- Indeed: Largest generalist job board globally. Competes indirectly through sheer scale and increasingly climate/sustainability tagged listings; a key incumbent benchmark for employer pricing and reach.
- ZipRecruiter: AI-driven job marketplace serving employers and job seekers across categories including sustainability. Broad incumbent competing for employer recruitment spend with a similar AI-matching narrative.
- LinkedIn: Global professional network with extensive climate-job listings. A broad incumbent whose professional network, scale, and any climate-vertical initiatives could compete with or overshadow Climatebase's niche positioning.
Direct peers
- Terra.do: Climate career accelerator offering fellowships, courses, and a talent platform to retrain professionals into climate roles. Highly comparable to Climatebase's Fellowship product and climate-career mission.
- Green Jobs Network: Long-running climate and sustainability job board with global listings. Operates in the same niche as Climatebase, serving sustainability job seekers and employers.
- ClimateTechList: Job board and directory focused specifically on climate-tech roles. Directly competes with Climatebase for climate-tech employer job posts and candidate traffic.
- WorkOnClimate: Climate-career community and job board connecting mission-driven professionals with climate jobs. Closest direct competitor to Climatebase, sharing the same target audience of job seekers and climate employers but with a more community/grassroots focus.
Others
- 80,000 Hours: Career-guidance organization helping high-impact professionals (including climate) find meaningful work. Adjacent rather than directly competitive, but overlaps with Climatebase's mission-driven job-seeker audience and content positioning.
Emerging players
- Climatebase (peer view) - Covalen / Wren Climate: Emerging climate-talent platforms and networks (e.g., Covalen) targeting climate-tech recruiting with specialized talent pools. Comparable mission and buyer profile but smaller scale and earlier stage than Climatebase.
