Ambrook, a New York company that makes accounting and finance software for farms and other independent businesses, raised a $30m Series B led by Lachy Groom. The round was announced in early August 2026.

What Ambrook does
Ambrook started with farms, which file different taxes and have more varied expenses than other businesses. It has since added trucking, contracting and real estate customers, according to Upstarts Media.
FinTech Global reported that the company has more than 8,000 customers across every US state, up from about 2,500 a year earlier, and that more than 1,000 of them are trucking operators. Upstarts reported that at least half of customers use Ambrook as their first software vendor, and that it has done best with farms with up to about $20m in sales.
Upstarts Media traced the idea to Burnett's early work on water access in California's Central Valley in 2018, when interviews with farmers showed that paperwork was the bigger problem.
Who is behind it
Upstarts Media named Mackenzie Burnett, chief executive, Dan Schlosser and Jeff Anders as co-founders, and said the company was founded in 2020. Burnett earlier co-founded a start-up that was sold to CoreOS. Schlosser worked as a product manager at Google and The New York Times, and Anders as a designer at Meta and head of design at Scale AI.
Teams are based in New York and the Bay Area, with commercial staff in rural Montana, and the company has offices in San Francisco and Denver. A headcount was not reported.
Who invested
Groom's own comments to Upstarts Media were about the effort behind small businesses: everything around us, he said, was built by someone who poured blood, sweat and tears into it.
Burnett told the outlet that very large businesses in the United States still run on paper, and that she does not think people realise it. In a letter on Ambrook's website she said the investment gives the company room to go further.
What the money is for
Upstarts reported that the funds will be used to move upmarket into larger agricultural businesses and to expand into construction, logistics and real estate. Ambrook also plans to build out payroll and operations features and a services function.
FinTech Global added that the money will go into product development for agriculture, trucking, general contracting, skilled trades and property management, and into AI tools and combined payments and cash management features.
Ambrook is hiring customer success managers and a services role, according to Upstarts Media.
