Meet a classic American success story

Hoffmann Brothers is a classic American success story, built on grit, craft, and a deep commitment to customer service.

It started in 1988, when 29-year-old mechanical engineer Robert Hoffmann left a stable job to acquire a small HVAC business in St. Louis. Over the next three decades, he grew it into a thriving $9 million company.

In 2015, Robert’s sons Chris and Joe took the reins. Chris, now CEO and a former Marine, and Joe, now General Manager and VP and a former sales engineer, set out to honor their father’s legacy while raising the bar for service.

They fused, as Chris puts it, “blue collar grit” with “white collar business strategy,” and grew Hoffmann Brothers to $160 million.

Today, the 600-person Hoffmann Brothers team remains proudly independent and focused on one thing: finding new ways to better serve customers.

That customer-first discipline shaped how they approached the AI wave.

Cutting through the AI noise

As a self-funded company, Hoffmann Brothers can’t afford expensive experiments. Every dollar has to earn its keep. When the AI hype hit, Chris and Joe approached the wave of “magic” solutions with caution.

Hoffmann Brothers chose to partner with Vantra for three main reasons:

A single AI platform for every revenue touchpoint: Rather than relying on 9 different systems, Hoffmann Brothers could use a single platform to streamline lead intake, outbound campaigns, revenue utilisation, and more.

Deeply understands operational rules: Other AI vendors offered “cookie cutter” solutions that fell short because they didn’t understand the nuances of Hoffmann Brothers’ revenue operations. Any business can configure Vantra to match its exact specifications.

A true partnership with a team of AI experts: Vantra’s engineering team has years of experience deploying AI into complex businesses. Hoffmann Brothers meets frequently with the team building the product to make it better.

Initially, I had a very healthy degree of skepticism. AI has become a massive buzzword. For every one good tool, there are 99 bad ones. I had to really pull at the thread to see what was real.

Capturing every lead when demand surges

In home services, demand swings fast, and you can’t staff for the worst day of the year without carrying overhead the rest of the time. Dispatch leader Nick Iadevito has seen peak days hit 1,000+ calls. “If a customer’s heat is out and it’s 10 degrees, they won’t wait on hold,” he says. “They’ll hang up and call the next company.”

Hoffmann Brothers first turned to Vantra as a solution for overflow and after-hours support to capture more demand. It handles autonomous intake across calls, texts, web chat, online widgets, and third-party leads.

The first big test came on May 16, 2025, when a major tornado struck St. Louis and caused more than $1B in damage. The call centre was flooded with homeowners in crisis.

Prior to Vantra, we would have seen abandoned call rates of 30% to 40% during a surge like that. With Vantra, we scaled our capacity instantly. Every caller got a response.

Booking the right jobs, every time

For a $160M operation, answering the phone is only step one. Not every call is equal, and under pressure, even great teams can slip on consistency.

Hoffmann Brothers didn’t want AI that simply “books a slot.” They needed an agent that follows the same playbook their team does: collecting the right details, prioritising high-value and urgent work correctly, and scheduling in a way that respects their capacity and operational rules.

Vantra follows Hoffmann Brothers’ workflows and enforces their booking logic end to end. It books directly into ServiceTitan, keeps routine requests from crowding out high-value emergencies, and recommends relevant add-on services at the right moment so customers get the right solution while average job value increases.

Without that consistency, you aren’t optimising for revenue. Vantra ensures the call is scheduled where it makes the most sense for the business.

From overflow support to Vantra First

Hoffmann Brothers began with Vantra in a familiar place: overflow and after-hours support to cover spikes, protect service levels, and make sure customers got a timely response.

As results held steady, they made a bigger move and went Vantra First.

Today, when a customer reaches out, Vantra’s AI is the first to engage across every channel, at every time of day. Hoffmann Brothers’ skilled team steps in when a personal touch is required, or when a situation calls for deeper judgement.

I’ve spent countless hours listening to these calls. I became increasingly confident that Vantra was ready to serve our customers at our standard. It’s been a game-changing partner because they’ve allowed our people to focus on the work only humans can do.

Filling the board during slow season

For CMO Angela Caputa, like many CMOs in the industry, shoulder season is the toughest stretch. Demand slows, and many companies end up on a paid marketing hamster wheel to keep crews busy. In some cases, paid search alone can eat up to $0.30 of every dollar they bring in.

Hoffmann Brothers chose a different path: generate more predictable demand from the customers they already serve—starting with their 20,000-member Home Protection Plan (HPP).

Vantra proactively reaches out to the right members at the right time via personalised text messages, handles complex conversations, and books appointments autonomously.

It uses data across internal operations (e.g., technician capacity), customer info (e.g., spend data), and third-party sources (e.g., weather, property data) to predict and capture customer needs.

The result: outbound booking rates increased from 5–10% to a consistent 25%.

With Vantra’s autonomous AI, our maintenance schedule fills up weeks in advance, without the chaos. We’re recovering thousands in missed revenue and providing a smoother, more convenient experience for our most loyal customers.

The impact on growth

Justin Schmidt, Senior Director of Performance Marketing, adds: “Vantra allows us to reach audiences targeted to specific goals and execute campaigns in a way no other platform can. It has fundamentally changed the feedback loop between our initiatives and our growth.”

We’re now able to combine customer data with external signals like weather patterns to target exactly who needs service, when they need it, instead of pouring our marketing budget into traditional lead generation channels which would have become oversaturated and costly. The ROI was obvious within weeks, not months.
