Costa Mesa-based defense firm Anduril Industries recorded the largest two-year revenue growth among the county’s large private companies, jumping five times over to $2.2 billion as of June 30.
The contractor also recorded the highest growth overall on this year’s list of fastest-growing private companies with its 424% increase. This list ranks privately held companies based on two-year revenue growth from 2024 to 2026.
This year, 45 companies with headquarters in Orange County recorded total revenue of $16 billion for the 12 months ended June 30, up 52% from two years ago.
The list is separated into three categories: small companies with annual revenue below $10.1 million; midsize firms between $10.1 million and $90 million; and large firms of over $90 million.
In total, the 45 companies employ 13,268 people across Orange County as of June.
Anduril, co-founded by Palmer Luckey, Chief Executive Brian Schimpf and three others in 2017, is reportedly exploring a financial boost that would increase valuation from $61 billion to $100 billion as it aims to revolutionize U.S. weapons production. The manufacturer is racing to produce weapons for the U.S. military faster and cheaper than long-established defense giants can.
After announcing $5 billion in financing in May, Schimpf said in a statement that the financing “gives us the ability to continue investing aggressively in manufacturing capacity, research and development, and the infrastructure required to build and field advanced defense systems at scale.”
Mortgage lender Kind Lending ranked No. 2 in the large category, nearly tripling its 12-month revenue to $184 million as of June 30 (see page 1).
“Orange County is an affluent, high-value market experiencing slower but relatively stable growth, creating an environment in which consumers are increasingly value-conscious, and businesses must emphasize differentiation, customer experience, and measurable return on investment,” Chief Financial Officer Brett Stubbs told the Business Journal.
Avanti Restaurant Solutions, which pushed into the large category for the first time last year with $99 million in revenue, maintained its growth trajectory in 2026. The contractor and designer of restaurant kitchens reported $138 million in 12-month revenue ended June 30, increasing 112% from 2024.
“In addition to continuing to grow alongside our national chain restaurant clients, we have expanded our design-build and contract capabilities, entered new market segments, strengthened our installation services, and broadened our geographic reach,” founder and CEO Mark Rossi said.
He added that projects like OCVibe are an example of “the scale of investment and development taking place locally” that Avanti can benefit from.
Small and Midsize Top Growers
Irvine-based Planet DDS joined the large company category this year reporting sales of $105 million for the 12-month period, increasing 34% from two years ago. Growth was driven by higher average sales per location for Denticon, its flagship product, according to CEO Eric Giesecke.
In the midsize category, Santa Ana-based Ornate Home Furniture and Mattress grew 12-month revenue by 275% to an estimated $15 million in the last two years. CEO Mehmet Uncuoglu credited the business’ growth to expanding its customer base, product selection, online presence and distribution capabilities in the face of overall cost-of-living pressures.
The second top grower is law firm Kahana & Feld LLP, which tripled revenue to $82 million from 2024.
“We’ve grown significantly, and we’ve been very intentional about making sure our technology, professional teams, and resources grow alongside the firm,” Kahana & Feld’s Chief Operating Officer Rina Hunter said.
“That includes continuing to expand our geographic footprint, investing in our summer associate program, adding exceptional attorneys and teams, and strengthening the capabilities we already have,” Irvine Managing Partner Sam Yu added.
Family-owned excavation company Chamberlain Backhoe Service landed in the midsize category for the first time this year after reporting $13 million in 12-month revenue, up 51% from the same period in 2024. Chamberlain said it aims to remain versatile in delivering excavation services, “whether it’s a new industrial building, public school, hospital or shopping center.”
The Partner Masters, an Irvine-based firm that offers tech support for Microsoft partner companies, captured the most growth among the 11 companies in the small category—a 266% increase in revenue to $9.5 million for the 12 months ended June 30.
“Microsoft has over 500,000 partners globally, and Microsoft pulled back much of its partner support a few years ago, leaving a huge gap,” CEO Justin Slagle told the Business Journal. “We exist to fill it. We do one thing, help Microsoft Partners run a more profitable Microsoft Partnership.”
The company is preparing to launch a new platform for clients that offers managed services, marketing services, licensing support and its own Partner Command Center software in 2027.
“Our growth has also been fueled by strong customer retention, expansion within existing accounts, and the development of new service offerings aligned to areas of highest demand,” Chief Financial Officer Jason Sutherland added.
