Kristina Subbotina never planned to start a law firm. She'd been a corporate startup lawyer for almost a decade, working at Cooley — one of the most prestigious Big Law firms in Silicon Valley. When she left her last job, she had a clear goal: join a VC fund as an investor.

To help attract potential portfolio companies, she started sharing legal tips for startups on social media. It worked — but not the way she expected. All the founders who reached out wanted legal support, not an investor. Some even started offering equity in addition to cash for her services.

"A couple of mentors told me that this is clearly a real problem in the market," she said. "They said to stop chasing what you think will be successful, and respond to what the world needs from you."

So she started her own law firm for startups called Lawlace. She grew it to over $1.3 million in revenue in just two years. The secret sauce? Social media.

In Big Law, there's a stigma around social media — the idea of a top-tier lawyer dancing on TikTok was cringe. But Subbotina operated from two principles: meet people where they are, and provide value. She started telling real legal horror stories with short videos — sometimes dancing, sometimes with comedy — because the entertaining format makes founders stop scrolling long enough to recognize a problem they're facing.

Those stories went viral. The videos received over 5 million monthly views, and Mark Cuban reposted her content. Instead of legal knowledge living only inside partner meetings, it reached founders where they already gave their attention.

But scaling a service business is hard. Legal work used to live only in lawyers' heads: manual, slow, and impossible to scale. So she started automating workflows right away. By late 2025, it was clear AI agents could do genuinely complex work — essentially the job of a junior associate.

That's when she started building Lexsy — an AI-powered legal operating system for companies. Clients buy a subscription and run their entire legal life on the platform, with human lawyers overseeing AI agents that handle the first pass on everything.

"We're an AI-native company, which means we have an army of AI agents that take a first stab at everything while senior team members set strategy and review," she explained. "That's how we grow fast without adding headcount."

Her team is lean: five people — Subbotina, a head of product and operations, and three software engineers — plus a handful of part-time support for the podcast, AI architecture, and social media.

She raised a small $650,000 funding round last year — intentionally picky about which investors she took money from. "If an investor couldn't help the business in other ways, such as media support or customer introductions, I didn't take their money."

When Lexsy came out of stealth in June 2026, it already had $372,000 in annual recurring revenue — from clients who migrated from the law firm, word-of-mouth growth, and her social following.

Her advice for service-business owners is direct: "Productize yourself. Keep the human touch for what matters, but automate execution. You don't have to be technical, and you don't have to raise venture money — you just have to provide value. That part never changes."
