## History and founding
Rob Mee founded Pivotal Labs, an agile software development consulting firm that EMC acquired in 2012; a year later it was spun out as [Pivotal Software](https://www.edgepedia.org/pivotal-software), where Mee served as CEO and the firm built and deployed Pivotal Cloud Foundry for clients.[3](https://www.mechanical-orchard.com/insights/the-seeds-of-mechanical-orchard) In 2022 he founded Mechanical Orchard to apply a similar iterative, developer-centered method to a different problem: enterprises' aging mainframe applications.[2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/)
The company launched in 2022 with funding from Spider Capital, Bloomberg Beta, and Cendana Capital, among others, according to its own announcement.[3](https://www.mechanical-orchard.com/insights/the-seeds-of-mechanical-orchard) Early leadership included COO Matthew Work, who previously held leadership roles at [Cognizant](https://www.edgepedia.org/cognizant) and Amazon; the February 2024 Form D lists Robert Mee, Matthew Work, Martine Boyer, and Riki Crusha as executive officers, with Work and [Jake Saper](https://www.edgepedia.org/jake-saper) as directors.[4](https://www.sec.gov/Archives/edgar/data/1953406/000195340624000001/0001953406-24-000001.txt) • [6](https://www.mechanical-orchard.com/insights/mechanical-orchard-secures-50-million-to-safely-transition-large-organizations-off-risky-legacy-software) The 2026 filing adds Cyrus Wadia, Edward Hieatt, and Joe Militello as officers, with Jake Saper and Crystal Huang as directors.[1](https://www.sec.gov/Archives/edgar/data/1953406/000195340626000001/0001953406-26-000001.txt)
## Products and technology
Mechanical Orchard addresses legacy systems that organizations depend on but can no longer safely change. Its founder describes the model as digital transplants: duplicating the behavior of orphaned black-box systems in a form optimized for change, and operating them for clients.[3](https://www.mechanical-orchard.com/insights/the-seeds-of-mechanical-orchard) In practice, the team reverse-engineers a legacy system's behavior and dependencies, then writes cloud-hosted code that replicates the old system's functionality. Customers own this code and can deploy it wherever they see fit.[2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/)
Generative AI serves as a "pair programmer" within this process rather than a replacement for engineers: Mee said the company always has developers in the loop debug and review the finished product.[2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/) The company says its iterative approach delivers each increment as working software into the production environment, giving customers continuous proof that the migration is working.[6](https://www.mechanical-orchard.com/insights/mechanical-orchard-secures-50-million-to-safely-transition-large-organizations-off-risky-legacy-software) GV, its Series B lead investor, frames the target problem as moving organizations off mainframes and COBOL in sectors including banking, airlines, retail, healthcare, and government.[7](https://www.gv.com/news/mechanical-orchard-ai)
## Funding by the numbers
The primary record is the company's SEC Form D filings (CIK 0001953406). The Series A offering had a first sale on 21 November 2023; the Form D filed on 9 February 2024 reported $26,249,994 sold to 16 investors, in Series A and A-1 Preferred Stock and convertible Common Stock.[4](https://www.sec.gov/Archives/edgar/data/1953406/000195340624000001/0001953406-24-000001.txt)
In August 2024 the company announced a $50 million Series B led by GV, which [TechCrunch](https://www.edgepedia.org/techcrunch) reported brought total raised to $74 million at that date.[2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/) The offering then continued to grow: a Form D/A filed on 16 January 2026 reported total sold in the Series B of $69,174,972, with nothing remaining, across 12 investors.[1](https://www.sec.gov/Archives/edgar/data/1953406/000195340626000001/0001953406-26-000001.txt)
These figures do not fully agree, and the differences are worth stating plainly. The announced Series B was $50 million, while the filed offering total is $69.17 million, meaning the round expanded well beyond its announced size between August 2024 and January 2026. Total raised is approximately $100.4 million per the Form D filings, $74 million per TechCrunch's August 2024 report, and about $102 million per PitchBook, a directory figure that is unverified.[1](https://www.sec.gov/Archives/edgar/data/1953406/000195340626000001/0001953406-26-000001.txt) • [2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/) • [5](https://pitchbook.com/profiles/company/515405-53) The Series B valuation has not been reported in the sources consulted.
## Business and traction
GV describes the customer base as teams in banking, airlines, retail, healthcare, and government moving off mainframes and COBOL.[7](https://www.gv.com/news/mechanical-orchard-ai) TechCrunch reported in August 2024 that the company had large enterprise customers in retail and logistics in its pipeline.[2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/)
Headcount grew steadily. The company said its team totaled 80+ in August 2024; TechCrunch put it at around 90 at the same time, a small unresolved discrepancy. By 2026, PitchBook listed about 117 employees, a figure carried only by that directory and unverified.[6](https://www.mechanical-orchard.com/insights/mechanical-orchard-secures-50-million-to-safely-transition-large-organizations-off-risky-legacy-software) • [2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/) • [5](https://pitchbook.com/profiles/company/515405-53) The company has an international presence in the UK, Ireland, Italy, and Germany.[6](https://www.mechanical-orchard.com/insights/mechanical-orchard-secures-50-million-to-safely-transition-large-organizations-off-risky-legacy-software)
## Recent developments
The trajectory since late 2023 runs from the Series A first sale in November 2023 through the February 2024 Form D, the April 2024 hire of ex-VMware executive Edward Hieatt as Chief Customer Officer, and the August 2024 Series B announcement led by GV.[4](https://www.sec.gov/Archives/edgar/data/1953406/000195340624000001/0001953406-24-000001.txt) • [6](https://www.mechanical-orchard.com/insights/mechanical-orchard-secures-50-million-to-safely-transition-large-organizations-off-risky-legacy-software) • [2](https://techcrunch.com/2024/08/07/mechanical-orchard-led-by-ex-pivotal-ceo-scores-50-million-round-led-by-alphabets-gv/) The Series B offering continued through amendments, closing its filed total of $69.17 million by the 16 January 2026 Form D/A, which also moved the company's recorded address from 530 Jackson Street to 1 Post Street.[1](https://www.sec.gov/Archives/edgar/data/1953406/000195340626000001/0001953406-26-000001.txt) • [4](https://www.sec.gov/Archives/edgar/data/1953406/000195340624000001/0001953406-24-000001.txt)
