Hang Ten Systems builds, modernizes and helps run custom software for large enterprises, using small forward-deployed engineering teams, AI coding agents and a library of reusable skills. Its engineers work alongside customers’ internal technology and operating teams on systems in areas such as finance, human resources and product development. The Palo Alto startup has closed a $53 million extension to its seed financing, bringing total funding to $85 million, the company told TechCrunch.
A project starts by defining what the software must accomplish and how its output will be checked. Engineers then use Hang Ten’s Hobie framework to direct and review coding agents, drawing on skills developed during earlier engagements. Customers or independent third parties still perform final quality checks and certification. Chief Technology Officer Sanjay Rajagopalan told TechCrunch that teams of two to four people can handle some projects that previously might have required about 30, though that comparison is a company claim rather than an independently measured result.
Hang Ten’s website says it prices engagements against a defined outcome agreed before work begins. Customers can also choose to have the startup host and manage the custom software after it is built. Its commercial pitch is a tenfold improvement in cost, delivery time or a combination of the two, shifting the sale away from the size of an implementation team and toward the completed system.
Xora, Temasek’s early-stage investment platform, led the $53 million extension, and earlier lead investor Mayfield participated. The round also included Aramco Ventures, Intel CEO Lip-Bu Tan, Micron CEO Sanjay Mehrotra and Yahoo co-founder Jerry Yang. TechCrunch reported that the extension closed five weeks after the initial $32 million seed financing; Hang Ten did not disclose its valuation.
Sikka said Hang Ten has secured multiple seven-figure contracts and is pursuing eight-figure engagements. He described a mix of existing customers and late-stage prospects spanning 21 large enterprises, with named customers including Fresenius Kabi, Saudi Aramco and Siemens Energy. The company currently employs about 20 to 25 people across the United States, the Middle East and Australia, and plans to add engineering, consulting and sales staff while hiring in Europe and India.
More than half of Hang Ten’s current opportunities involve projects that companies had previously postponed, according to Sikka, while other engagements replace incumbent service providers. That makes the business more than a bid to automate existing consulting work: it is also trying to make uneconomic software projects practical. The specific test is whether Hobie and small delivery teams can preserve reliability as the company takes on more regulated, mission-critical systems without shifting final verification into a new bottleneck.
