async

In pursuit of excellence

Async builds specialized AI agents for small and mid-sized businesses that sit outside the typical enterprise AI buyer profile, with early deployments inside law firms, healthcare clinics and real estate companies . The pitch behind this launch is that AI adoption in this segment has lagged far behind larger companies, and closing that gap takes more than another horizontal chatbot. Async pairs agent builds with hands-on change management, helping teams pick workflows, deploy into existing systems, and ease staff concerns about what automation means for their jobs. The company works through a four-step process that starts with auditing a customer's tech stack and internal workflows, agreeing on one or two scoped workflows, then building and deploying agents into existing systems before expanding coverage over time . Async maintains and iterates on each deployment so the agents improve with each action , which is aimed at operations work that has historically been too complex or too low-volume to justify hiring for. Async was founded in 2025 by Connor Park and Ben Smith and is part of the Y Combinator S26 batch. Smith previously sold shoes, trading cards and collectibles before dropping out of college at 20 to build software , and Park studied Computer Science at the University of Michigan, Ann Arbor . The launch matters now because a wave of YC S26 companies is targeting the same "agents inside real businesses" thesis, and Async is staking out the SMB professional services corner of that market.
