The 22-Year-Old Automating America's Trades
A dropout's bet: from quantitative finance to building the AI platform behind the next generation of home-service businesses.
By Leonardo Camilleri

Leonardo Camilleri just wanted his plumber to pick up the phone.
Call after call went unanswered. For Leonardo, then studying quantitative finance at NYU Stern, the experience raised a bigger question: how much business slips away when the people doing the work are also responsible for answering every call?
He left his master's program, built a solution, and took it door to door across Manhattan, selling it to contractors one conversation at a time.
Semperly now works with over 20 businesses. For one contractor, it booked more than 700 jobs in two months, that's about $200,000+ in revenue recovered.
"Missed calls and emails are the most expensive cost a home-service business never sees. That's where Semperly comes in."
That solution became Semperly. Today, the company is expanding beyond AI call answering with a larger ambition: change how home-service businesses run.
Built for the Work Behind the Work
HVAC technicians, plumbers, electricians, roofers, and cleaning crews keep homes and businesses running. Behind every service call is another layer of work: answering inquiries, coordinating appointments, following up, and keeping customer records current.
For an owner building a company, that workload can become a second full-time job. A growing schedule brings more messages, more coordination, and more opportunities for something to fall through the cracks.
Semperly is building an AI automation platform to help home-service businesses handle that operational load. Its goal is to give teams more capacity to serve customers without making the owner the point of contact for every task.
A Founder Who Saw a Bigger Opportunity
Camilleri brought experience in investment banking at Rothschild and Equita and software engineering at Fanfix. With Semperly, he turned his attention to a different kind of business problem: the everyday friction that keeps skilled service professionals tied to administrative work.
The unanswered call was the starting point. The opportunity was everything that happened around it.
One Platform, a Broader Ambition
Semperly's AI receptionist helps businesses answer incoming calls and assist with appointment scheduling. But a customer conversation rarely ends when the phone hangs up. Details need to be recorded, schedules need to be coordinated, and follow-up questions need a response.
That is why the platform extends to AI Inbox, scheduling, and CRM automation. AI Inbox drafts customer email replies for a team member to review and approve. Scheduling and CRM workflows support the coordination and recordkeeping that turn an inquiry into work a team can act on.
These products serve a shared purpose: reduce the repetitive work surrounding each customer interaction and help the business keep moving.
For Semperly, answering the phone is one part of a much bigger vision for the front office.
More Room to Grow
Semperly's ambition is to give a small crew the operational capacity to pursue bigger opportunities. That means helping owners build a business that can respond to customers while they focus on delivering the service, leading their teams, and planning what comes next.
People remain central to that vision. Their expertise, judgment, and customer relationships are what make a service business worth calling. Automation should give them more room to put those strengths to work.
One missed connection pushed Camilleri to build a product. Now, he is building a company around the belief that the trades deserve better systems behind them.
The phone was the beginning. Semperly's next chapter is about the business around it.
