Ciridae Raises $20 Million for AI Services Targeting Mid-Market Companies

U.S. mid-market businesses often overlooked by Silicon Valley. The round was led by Accel, with participation from Andreessen Horowitz and General Catalyst.

Co-founders Jack Soslow, a former a16z partner, and Jack Weissenberger, a former Apple and Tenyx machine learning lead, positioned the startup as a response to an existential risk for companies in sectors such as home services, construction and industrial distribution. Jack Soslow said many of the businesses most exposed to AI risk are least equipped to do this rearchitecture themselves.

These are businesses in home services, construction, industrial distribution—the businesses that compose our real economy—and if they don’t do it, they will be out-competed and atrophy over time,” he told Fortune. The company will initially focus its services on companies backed by private equity. Ciridae had high seven-figures of revenue in 2025 and works with more than 20 partners.

One early customer, a Dallas-based commercial construction company, saw its operations transformed when Ciridae replaced its CRM, project management and working capital tools with an AI operating system. The construction company cut the time it took to complete its monthly accounting processes from two weeks to a single click, Jack Weissenberger said.

Jack Weissenberger described the startup’s approach as enabling existing operations rather than replacing human labor.

“We’re not building AI that’s actually mowing the lawns. We’re just helping enable them to mow more lawns at a more regular cadence. What the end consumer is seeing is just, ‘Hey, my lawn care service is way better,’” he said.
