Stackless Data

Stackless Data (栈略数据) is a Shanghai-based insurtech company focused on health insurance risk control and digitalization, founded in 2016 with founding team members from Silicon Valley tech companies . The company positions itself as a vertical player in health insurance rather than a generalist fintech firm, offering enterprise-grade big data risk control solutions to commercial insurers, insurance intermediaries, and government medical insurance departments .

The company has raised multiple rounds, including a nearly RMB 100 million Series B led by Lingfeng Capital in 2019 , and a nearly RMB 200 million Series C+ round led by Qiming Venture Partners in late 2023, with follow-on from Suzhou Yihe and continued support from Legend Capital . Gaorong Capital, an early backer from the 2016 angel round, also participated in subsequent rounds .

Stackless Data's core business centers on two pillars: intelligent audit systems for medical insurance fund supervision, combining online AI review with offline spot inspections; and a one-stop digital platform for commercial insurers that integrates automated operations with big data risk analysis across the full insurance value chain from product design to claims . The company established an international headquarters in Hong Kong in 2019 to expand across Asia .
