Company profile
researched Aug 20264AG Robotics develops fully autonomous, vision-guided robots that pick, trim and pack mushrooms for commercial growers. The systems retrofit onto the standardized "Dutch-rack" shelving already used by modern mushroom farms, requiring no changes to farm infrastructure, and are transportable between growing rooms. Products include bulk-box harvesting robots (the Forager HX-400 is cited in coverage) and a punnet-packing robot, the Forager HX800, described by the company as forthcoming. The robots combine computer vision, patented precision suction-cup grippers and advanced motion control to harvest around the clock.
Beyond the hardware, the company positions itself as an AI business: its vision system maintains a map of every mushroom on a bed every 30-90 minutes, models growth rates and competition between neighbouring mushrooms, and uses farm-annotated images to train picking decisions to each grower's product specifications. Size and weight data captured at pick time feed continuous optimization, and additional models cover disease and contamination detection and alerts on abnormal growth rates in rooms. The company also lists upcoming features in punnet packing, disease detection and AI-driven yield optimization.
The company is headquartered in Salmon Arm, British Columbia, where it manufactures its robots, and has an operating team led by CEO roles reported variously in the sources; company materials list Nick Pattinson as CEO, while July 2025 press coverage quotes Sean O'Connor as CEO, with Chris Payne as COO and Michelle Lim as VP of Growth. Other listed leaders include Chief Product Officer Robbie Edwards, VP of Operations Keiran Fitzpatrick, VP Finance and Business Operations Steven DeBoer, and VP Mechatronics Nate Tomlinson. Board members include Jonathan Goodkey (BDC Venture Capital), Harry Briggs (Astanor), Mel O'Rourke, Don Listwin and Keith Spencer.
Founding story
The business was founded in 1999 as TechBrew Robotics, operating for years as an engineering firm that built one-off robotics solutions for industries including food, medical devices and transportation. Roughly six years before 2025, TechBrew pivoted to developing a product for the mushroom industry.
Business model
4AG Robotics sells its harvesting robots to mushroom farms up front and layers a recurring revenue component alongside the hardware, supported by service level agreements for ongoing support and maintenance. New farm customers typically start with an initial deployment of eight to 12 robots and expand fleets from there.
Upfront robot sales combined with a recurring revenue portion of the business, plus service and maintenance commitments under service level agreements. Reported revenue was CAD/USD 2.5 million in the prior year with a target of $7 million by the end of 2025, per company statements in press coverage.
Traction
Robots are live on farms across three continents: Highline Mushrooms in Canada since March 2024, Monaghan Mushrooms in Ireland since December 2024, and an unnamed Oceania-region farm since December 2024, with South Mill Champs (Canada), a US farm and Banken Champignons (Netherlands) targeted for 2025. The company reports 53 robots sold, deposits for over 40 more, production sold out into February 2026, and about one million mushrooms picked per week. Revenue was reported at $2.5 million in the prior year, tracking toward $7 million by end of 2025. Headcount stood at 78, of whom 66 were full-time, with plans to add 30 field service and customer success staff.
Latest developments
In July 2025 the company closed an all-equity, all-primary CAD 40 million Series B led by Astanor and Cibus Capital, with new investor Voyager Capital and existing backers InBC, Emmertech, BDC Capital's Industrial Innovation Fund, the James Richardson & Sons family office, Stray Dog Capital and (per one report) Seraph Group. The round was oversubscribed, and management said it also plans to raise an additional $10 million in debt financing. Proceeds are directed at expanding the Salmon Arm manufacturing site, building field service and customer success teams, and developing punnet packing, disease detection and AI yield optimization features. The company also announced a Vancouver expansion with an open house in July 2025 and was named among Canada's Top Growing Companies of 2025 in September 2025.

Market position
The company describes itself, and is described by investor Astanor, as a leader in autonomous mushroom harvesting; Cibus Capital states 4AG's robots already pick over one million mushrooms per week. Coverage notes that few companies globally have replaced human hand-picking of a produce item destined for grocery retail. Company materials cite a global mushroom market projected at $60 billion by 2030 (one funding article references a $70B industry), and note North American, European and Australian markets produce close to 900,000 tonnes of fresh mushrooms annually.
Retrofit design that mounts to standard existing Dutch-rack shelving without farm reconfiguration; patented suction-cup picking claimed to match human hand quality; 24/7 operation; and a data/AI layer that continuously retrains on per-mushroom outcomes, which the company argues yields a rate of learning unique in agriculture. Management emphasizes deployment in live, complex farm environments rather than lab settings, and reports payback for growers of roughly 18-30 months (ROI under three years) depending on local labour costs.
Technology
Vision-guided autonomous robotics: computer vision builds a map of every mushroom on a growing bed every 30-90 minutes, tracking growth rates and spatial competition to determine optimal pick timing; patented precision suction-cup grippers and advanced motion control perform picking, trimming and packing. Farms annotate images to encode their own grading standards, and per-mushroom size and weight data at harvest feed model retraining, with updates implemented weekly. Additional AI models address disease and contamination detection. Units mount to existing 4-metre farm shelving and move between growing rooms.
Go-to-market
Direct sales to mushroom growers, beginning with on-farm trials and prototype deployments with early adopters such as Highline Mushrooms and Champs Mushrooms, then expanding via follow-on orders and fleet expansion within a highly consolidated customer base. The company reports it has sold 53 robots and holds deposits for more than 40 additional units, with capacity sold out into February 2026. New funding is earmarked for field service and customer success teams to support deployments.
Commercial mushroom growers, primarily large and consolidated farm operators in North America, Europe and Australia, with Asia (including China, which produces about 70% of the world's fresh mushrooms) identified as a later market. Named customers include Highline Mushrooms (Canada), Monaghan Mushrooms (Ireland), South Mill Champs, Banken Champignons (Netherlands) and an unnamed farm in the Oceania region.
Geography
Headquartered and manufacturing in Salmon Arm, British Columbia, Canada, with an expansion to Vancouver announced in July 2025. Robots are deployed in Canada, Ireland and Australia, with planned deployments in the United States and the Netherlands. Investor materials also associate the company with Listowel, Canada. Manufacturing is intentionally retained in Canada given demand from multiple countries outside the US.
History
Founded in 1999 as TechBrew Robotics; pivoted to mushroom-industry robotics around 2019; hired Sean O'Connor, formerly managing director of Conexus Venture Capital and Emmertech, in 2023 and rebranded as 4AG Robotics later that year. It raised $17.5 million in late 2023, went live with its first commercial deployment at Highline Mushrooms in March 2024, added deployments in Ireland and Oceania in December 2024, and closed a CAD 40 million (about $29 million USD) Series B in mid-July 2025, bringing total capital raised to a reported $57.5-60 million.
Risks & controversies
Adoption depends on capital-intensive hardware sales into a small, highly consolidated customer base, with some growers preferring to observe results for a year or two before purchasing. Management notes tariffs on Canadian goods entering the United States as a factor it monitors while continuing to manufacture in Canada, and states the business is not dependent on the US market. Coverage also notes Canada lags in later-stage funding for foodtech, per a Canadian Food Innovation Network report. Capacity is currently sold out into February 2026, indicating supply constraints relative to demand.
