Andreessen Horowitz is backing a startup that's deliberately ignoring the Fortune 500 to focus on the businesses most at risk from AI disruption: mid-market companies in construction, home services, and industrial distribution that have no idea how to modernize. Ciridae, which just raised $20 million in seed funding led by Accel with participation from a16z and General Catalyst, is betting that the real opportunity in AI isn't in flashy enterprise software for tech giants, but in helping ordinary businesses survive the coming wave of automation.

The startup was founded by Jack Soslow, a former partner at a16z, and Jack Weissenberger, who previously led machine learning efforts at Apple and Tenyx. Together, they've identified a massive blind spot in the AI investment landscape: the thousands of mid-market businesses that compose America's "real economy" but lack the resources or expertise to rearchitect their operations around artificial intelligence.

Why Are Mid-Market Businesses So Vulnerable to AI Disruption?

The problem is stark and urgent. These companies face an existential threat from AI, yet they're the least equipped to handle it themselves. Unlike Fortune 500 firms with dedicated technology teams and massive budgets, mid-market businesses in construction, home services, and industrial distribution operate with lean back-office teams and legacy systems that have worked for decades. When AI starts automating tasks across their industries, they risk being out-competed by more agile rivals.

"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," said Jack Soslow, co-founder of Ciridae.

Ciridae's approach is refreshingly practical. Rather than building flashy AI products, the startup works with mid-market companies to solve unglamorous but critical problems: untangling back-office headaches, automating scheduling around workplace dynamics, and replacing fragmented tools with unified AI operating systems. The startup has already found traction, working with more than 20 partners and generating "high seven-figures" in revenue during 2025.

How Is Ciridae Actually Helping These Businesses?

One concrete example illustrates the impact. Ciridae worked with a Dallas-based commercial construction company to replace its customer relationship management (CRM) system, project management tools, and working capital management with an integrated AI operating system. The result was dramatic: the company cut its monthly accounting close process from two weeks down to a single click.

This isn't about replacing workers with robots. It's about enabling existing teams to work more efficiently and consistently. Weissenberger explained the philosophy behind the company's approach to addressing concerns about AI and employment.

"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,'" said Jack Weissenberger, co-founder of Ciridae.

Ciridae's initial go-to-market strategy focuses on private equity-backed companies, which makes sense: PE firms are actively looking to modernize portfolio companies and improve operational efficiency before exit. This positions Ciridae at the intersection of two powerful trends: the AI transformation wave and the PE industry's relentless focus on operational improvement.

Ways to Identify Which Mid-Market Businesses Need AI Modernization

• Back-Office Inefficiency: Companies spending weeks on monthly accounting closes, manual data entry, or fragmented tool ecosystems are prime candidates for AI-driven consolidation and automation.
• Scheduling and Coordination Challenges: Businesses struggling with workforce scheduling, customer coordination, or resource allocation across distributed teams can benefit from AI-powered optimization.
• Limited Tech Infrastructure: Companies without dedicated technology teams or modern software stacks are most vulnerable to disruption but also most likely to see dramatic improvements from AI integration.
• Industry Exposure: Sectors like construction, home services, industrial distribution, and commercial trades face direct competition from more tech-forward rivals and need rapid modernization to survive.

What makes Ciridae's positioning notable is its focus on what Accel partner Christine Esserman called the overlooked segment of the market. While venture capital obsesses over enterprise AI for large corporations, Ciridae is targeting the businesses that actually need help most.

"Everybody's trying to focus on this top enterprise segment. And a lot of people are ignoring the $200 million top-line restoration business in Texas that actually wants to use AI but has no idea how to do it," said Christine Esserman, partner at Accel.

The founders also acknowledged a cultural challenge: many Americans, including employees at the businesses Ciridae serves, harbor concerns about AI in the workplace. But they argue that by successfully deploying AI to improve service quality and business efficiency, Ciridae can help shift perceptions. When customers see better service and employees see their jobs becoming less tedious, skepticism tends to fade.

This investment reflects a broader trend in venture capital where firms are looking beyond the obvious AI winners to find opportunities in AI-led business transformation. Long Lake, an investment and holding firm, recently purchased a corporate travel platform for $6.3 billion specifically to modernize it using AI. Ciridae represents the same thesis applied to the fragmented mid-market: there's enormous value in helping ordinary businesses adapt to the AI era, even if the story isn't as glamorous as building the next ChatGPT competitor.

For a16z, the investment signals confidence that the real AI opportunity isn't just in building cutting-edge models or selling enterprise software to tech companies. It's in helping the backbone of the American economy, the thousands of mid-market businesses that employ millions of people, navigate the transformation ahead. That's a much larger market than most investors are paying attention to.
