Building @probookai - the AI operating system for HVAC, Plumbing & Electrical companies. Building in public and sharing lessons from the field.

Announcing $40M in funding from @sequoia and @a16z.

I grew up pressure washing houses in upstate New York. Six summers in the truck, missing calls from the top of a ladder because I couldn't hear my phone ring. My co-founder Ben grew up plumbing with his dad in San Francisco.

We entered home services because we grew up in it. I spent a summer inside TR Miller, one of the best-run HVAC, plumbing and electrical shops in the country, and their workflows were still raw.

The first wave of AI in the trades was point solutions. One tool for voice, one for outbound, one for follow-up. Operators ended up with five vendors and more overhead.

Probook is the AI operating system that helps you add points to your EBITDA and run your entire customer experience as one connected system, built around dispatch.

Many of America’s largest home service brands run on Probook today. Summers Plumbing booked 2,542 jobs their first month with us, zero human intervention. Anthony PHCE ran 20% more revenue per job on a 50% leaner team. Del-Air more than doubled productivity from 10 to 22 techs per dispatcher.

To everyone who trusted us early: thank you.

Back to work. We're hiring.

@hewarsaber Thanks for sharing!

[a16z @a16z]

We're excited to lead Probook's $34M Series A.

Every home services business runs on dispatch: which technician goes to which job, in what order, at what time.

Almost every AI vendor building for the trades skipped dispatch, instead rushing to build voice agents and chat widgets.

@probookai built dispatch first, then expanded outward into intake, data scrubbing, messaging, and outbound. Every customer stays on one text thread from the first call to the technician at the door.

@georgeprobook grew up in the trades, pressure washing alongside his dad, and spent a summer inside a $40M HVAC shop before building the software to fix it.

Welcome, George, @probookcto, Ben, and the entire Probook team.

At @sequoia we help founders building legendary companies. My favorite kind of founder has deep, authentic connections to the industry they're transforming. @georgeprobook is that kind of founder:

George grew up the son of a NYC cop. His dad got injured, forcing retirement. He got into the trades and started power washing houses, bringing George with him. George spent much of high school in the truck, learning the trade. He was a smart kid. He earned a perfect 36 on his ACT and got into the Ivy League, studying the prestigious M&T program at University of Pennsylvania. But he did not desert his roots. He kept working with his dad through college, and worked at a home services shop in Illinois that later became Probook's first customer. Eventually, he took some of his AI skills he learned at college to automate the kind of work his dad hated doing: scheduling, logistics, back-office. Then, he offered it to other operators like his dad. Before he knew it, Probook became a smash hit in the home services industry.

George had technical chops- but he needed someone who could take Probook to the next level. That's @probookcto . Lewis is a genius. This is a guy who earned a perfect score on the American Mathematics Competition. That isn't a top 1% thing, that is something only 10 out of 45,000 top math competitor achieve. Then, he went to UC Berkeley where he proceeded to early an Electrical Engineering Computer Science (EECS) degree with a 4.0 GPA...in 2 years flat! I heard phenomenal reviews about Lewis from my friends at Roblox, where he was top of the pack for young engineers. But most remarkably, Lewis is truly a ray of sunshine. Go look at his web profile. You'll see him smiling. He ALWAYS has that smile. Like 100% of the time. Even during the hardest moments. He has such a strong mental fortitude (and back strength...man he can do pullips) that he really inspires me.

Probook's third and final co-founder, Ben Cervantez, grew up in SF where he was Valedictorian, Captain of Varsity Football, played Varsity Baseball, and earned a perfect 36 ACT. Yes, the full package. He Attended Wharton's prestigious M&T Program where he played Men's Rugby. But when he learned about George and Probook, he took a bold move and dropped out to go full-time. This was extremely high risk, but clasically Ben's style. He's low ego and high performance. He always puts the team first. Ben Cervantez is the glue that holds this team together. He works tirelessly, flies non-stop to customers, and lives with extreme customer love.

Because of the authentic connection and customer love, customers love Probook. As one customer wrote, "If you take Probook away. I quit." The growing like crazy, hiring an incredible in-person team in NYC, and really serving the trades industry with care.

If you can't tell, I really love working with this team. I love being their "coach." These daring founders are the real deal in every way.

Congratulations to my friends and partners on the fundraise!!

Probook, a New York–based AI dispatching platform for home services operators, has raised a $34 million Series A led by Andreessen Horowitz and Sequoia Capital, bringing its total funding to $40 million. Founded by CEO George Eliadis alongside CTO Lewis Zhang and co-founder Ben Cervantez, the company builds software that uses historical shop data to match the right technician to the right job in real time, then expands into intake, customer messaging, and outbound workflows to unify the full customer experience and improve operator margins.

FUN FACT: Probook was built by people who grew up in the trades. CEO George Eliadis spent six summers pressure washing in a truck in upstate New York with his dad, then spent a summer working inside TR Miller - a $40M HVAC/plumbing/electrical shop in Illinois that became Probook’s first customer. Co-founder Ben grew up plumbing alongside his dad in San Francisco.

For most of @probookai history, our entire sales team was one person. Me.

People would walk up at conferences and ask where our sales team was. "You're talking to him."

I came up in the trades before starting this, so when I sit across from a GM running a $50M home service business, we speak the same language.

That doesn't scale. So we're hiring our first real GTM team. More to come.

Logos on a website don’t mean much.

Renewals and expansions do.

Helmi and the Guaranteed Service team have been with us for years and recently doubled down. These are the reviews we strive for.
