Leading plant-based meat maker Rebellyous Foods has commercially launched its Mock 3 Production System on the back of a 30% sales growth and $3.5M in new funding.
In the alternative protein world, most companies continue to face struggles with scaling up, lowering costs, and raising capital to do so. Rebellyous Foods isn’t one of them.
The Seattle, Washington-based firm has launched its proprietary Mock 3 Production System, which converts conventional plant-based meat production into a continuous, automated process on a commercial scale.
This allows the startup to match the high-volume production levels of conventional chicken and further slash the costs of its vegan alternative.
It comes on the back of a “banner year” for Rebellyous Foods, which saw year-on-year sales shoot up by 30% with strong margins. Additionally, it secured $3.5M in new funding in November to support its 2026 expansion plans.
Mock 3 accelerates bid for plant-based meat price parity
Protected by 14 US and international patents (and six more pending), the Mock 3 system has been years in development. It enables the continuous, “just-in-time” production of plant-based meat substrates with only a fraction of the labour typically needed for such processes. That helps deliver considerable cost savings to Rebellyous Foods’s customers.
Mock 3 is able to produce over 5,000 lbs of vegan chicken nuggets, patties and tenders per hour, and marks the company’s return to Washington state (it has been operating its Mock 2 system at RMS Foods’s facility in New Mexico).
“Production cost-parity is not just about scale. Targeted manufacturing technology development is key to providing cost-parity alt-protein products. That is what we’ve delivered with Mock 3 at the end of 2025,” said Cruz Philippe, a mechanical design engineer at the firm.
He has been developing this technology since 2021, and brought the system to commercialisation at the end of December, successfully running Mock 3 over two days. “We were able to sustain steady state operation through multiple shifts and to scale up/down as needed in real time to support downstream processing rates,” Philippe explains.
Rebellyous Foods has already been offering price-competitive plant-based meats and the commercial launch of Mock 3 will enable it to double down on its cost reductions.
That is critical to expanding consumer adoption in a country where vegan alternatives remain 82% more expensive than conventional meat products. It’s why price is now the biggest barrier to eating more plant-based foods in North America, as cited by 48% of consumers. However, research also shows that 44% of Americans would buy plant-based proteins instead of meat if they’re cheaper.
Lower prices will enable expansion in school lunch programme
“Crossing this commercialisation finish line was as challenging, if not more challenging, than developing the technology itself,” said Rebellyous Foods CEO Christie Lagally Bradburn, a former Boeing engineer who founded the startup in 2017. “But real-world application of this technology means full realisation of the investment in time and money we’ve put into achieving cost-parity alt-meat production.”
The company’s products are available in 45 US states now, and each of its seven SKUs qualifies for the USDA National School Lunch Program, allowing foodservice operators to supply affordable and sustainable protein options.
“We are truly democratising access to plant-based meat replacements,” said chief business officer Tina Meredith. “No longer is alt-meat only available to those who can afford premium products. The Mock 3 Production System enables price parity for the most cost-sensitive market: the USDA National School Lunch Program.”
As of mid-2025, Rebellyous Foods’s meat alternatives reached over five million students in more than 390 school districts nationwide.
“It was a momentous final week of 2025 to see that plant-based meat can be made fully continuously, automated in high volumes, and with considerably reduced labour compared to conventional methods, commercially,” said Lagally Bradburn.
