What Ai4 does
Ai4 is a B2B conference and events company founded in 2018 and headquartered in Brooklyn, New York, that organizes what it bills as "America's Largest AI Conference." The company's core product is an annual flagship event — Ai4 2026 scheduled for August 4–6, 2026 at The Venetian in Las Vegas — comprising 1,000+ speakers across 80+ tracks, 400+ exhibitors, and 12,000+ expected attendees from 90+ countries. Supporting products include tiered conference passes (Standard $2,295–$3,195, VIP $3,495–$5,995, plus startup, government/academic, and media tiers), pre-conference AI training courses delivered in partnership with General Assembly ($395 per 4-hour session), an applied AI research conference (AAIRC) co-hosted with the California State University Chancellor's Office, and executive Leadership Summits. The company's technology stack consists of a conference management platform with a private networking app, an AI-powered agenda builder tool, and registration systems.
Ai4's revenue model rests on three streams: attendee registration fees, exhibitor and sponsor packages (with major technology vendors such as NVIDIA, AMD, AWS, Cisco, Google Cloud, and IBM as anchor sponsors), and paid training add-ons. The target buyer mix spans enterprise C-suite executives, technology leaders and AI practitioners, AI/technology vendors seeking lead generation, academic researchers, and investors/VCs. Distribution is primarily direct via the ai4.io website, supplemented by corporate sponsorship sales and an open speaker application process.
In March 2025, Ai4 was acquired by CloserStill Media, a diversified global events group, with advisory support from JEGI CLARITY. The legal entity now operates as CloserStill Ai4, LLC. The company employs 11–50 people and was recognized in the top 20% of America's fastest-growing private companies on the Inc. 5000 list, reflecting sustained growth in the post-acquisition period.
