ProLine closes $9.6M Series A to accelerate the AI platform for roofing contractors

There are 84 million single family homes in the US, and every one of them has a roof. Over 100,000 roofing contractors do more than $50 billion in roofing work each year, and the trade gets more professional and better capitalized every year. When we made our first investment in ProLine in March 2025, our thesis was simple: the contractors winning this market would be the ones running on software built for roofing with AI at the core, and ProLine was building exactly that.

Sixteen months later, the results are in.

We're excited to share that ProLine has closed a $9.6 million Series A financing led by San Francisco-based Growth Street Partners.

The new capital will accelerate product development, expand ProLine's go-to-market efforts, and continue building the leading AI platform for roofing contractors.

What ProLine has built since our investment

Back in 2021, AJ Briley teamed up with roofing entrepreneur John Delaurier to build a new type of software for the roofing trade. ProLine is "for roofers who want to dominate their market & still make it home for dinner." The platform combines customer phone, text, and email communications with AI-enabled automation to run an entire roofing operation from sales to production to payments, as the system of record for the business.

The company has since grown annual recurring revenue more than 4x since our investment, continuing to take share from legacy vendors that were not born in the age of AI and winning contractors who want their software to work the way their business actually runs.

This is what we look for across the portfolio: fast growth paired with capital efficiency, in a vertical market where the AI-native product is meaningfully better than what came before. ProLine has proven both sides of that equation in one of the largest essential-industry markets in the country.

Why this round matters

A Series A led by a quality growth investor is external validation of what we've watched from the inside since 2023. Growth Street Partners underwrote ProLine's numbers, its product, and its team, and concluded what we concluded: Vertical AI platforms solving mission-critical workflows inside traditional industries are creating durable, category-winning businesses.

We first made this argument when we invested in ProLine, and again with Madison AI in local government and Swivl in self storage. The pattern keeps repeating. Essential industries run on workflows that legacy software never fully captured, and AI-native platforms are capturing them now.

Congratulations to AJ, John, and the entire ProLine team on this milestone. Team CreativeCo is proud to continue supporting the company as it builds the market-leading platform for roofing, and we look forward to what comes next.

ProLine joins Madison AI (AI agents for local government operations), Swivl (AI agents for self storage operators), and Churnkey (revenue retention automation for subscription businesses) in our CreativeCo Fund III portfolio.
