Forum Ventures Fall 2026 Cohort: 15 AI-First B2B Startups

Forum Ventures, a B2B fund, accelerator, and venture studio, has selected 15 companies for its Fall 2026 AI-first accelerator cohort. Thirteen are announced below and two are in stealth.

Forum Ventures received about 3,000 founder applications for the Fall 2026 cohort. The cohort represents the top 0.5% of that pool.

Most of the cohort applies AI to physical or regulated industries: manufacturing, construction, mining, maritime, space, healthcare, and restaurants. The rest build for the back office and for AI itself, covering software spend, accounting, training data, and data center cooling.

How the Program Works

Forum Ventures runs a cohort program, but not a fixed curriculum. Each cohort is intentionally small, and support is built around what each company needs at that moment. Forum Ventures invests $100K for 7.5% on a post-money SAFE, then works with each company from day one.

Weekly 1:1 work with a dedicated Managing Director

Every company is paired with a Managing Director, a former founder or operator, who works with the founders 1:1 each week on customers, go-to-market, product, and fundraising. The program includes at least 15 hours of direct one-on-one time. Extra support is available through weekly labs, optional skills sessions, and founder socials.

Customer introductions

Founders meet senior executives through Forum Ventures' industry councils in builtworld, healthtech, fintech, and supply chain, and through its wider enterprise network. These conversations help founders get early product feedback, find design partners, and win their first customers.

Fundraising support

When a company is ready to raise, Forum Ventures helps the founders set a target date, build an investor list, sharpen the narrative and pitch deck, and run an effective process. Companies present at one of four annual Investor Showcases and receive warm introductions across a network of 3,000+ Seed and Series A VCs, angels, and family offices.

Community and ongoing support

Founders join a community of 1100+ B2B founders. Forum Ventures has offices available for co-working in New York City, San Francisco, and Toronto, and founders can also work remotely. Companies receive $100K+ in business perks, and support continues after the program ends.
