Redbrick AI, a health-tech platform that harnesses artificial intelligence, said it raised $4.6 million in a funding round led by Sequoia India and its Southeast Asia startup accelerator, Surge. The round also saw participation from Y Combinator and angel investors.

Founded in 2021 by University of Michigan alumni Shivam Sharma and Derek Lukacs, the company aims to provide solutions for building medical imaging AI. Its SaaS platform offers web annotation tools for 2D and 3D data to give experts access to specialised tooling right from their browsers.

“With the rapid growth of artificial intelligence in clinical settings, researchers need excellent tools to build high-quality datasets and models at scale. Our customers are in the vanguard of this growth, pioneering everything from surgical robots to automated detection of cancers. The new funds will be integral to the growth of our engineering team in India and to expand our suite of products,” said Sharma, the company's CEO, who previously worked on SpaceX’s Hyperloop project with Lukacs.

Researchers and healthcare institutions are increasingly investing in AI solutions to improve diagnostics, treatment, and quality of care for patients. The use of AI in healthcare has the potential to transform patient care by boosting clinician productivity and automating clinical diagnosis. In 2021 alone, the US Food and Drug Administration (FDA) approved 115 AI algorithms for use in medical environments, an 83% increase from 2018.

RedBrick AI’s tools aim to address challenges unique to medical data annotation, such as the complexity of existing annotation tools, quality control, and machine learning integration. The company joins a growing list of health-tech startups that have received funding in the past few weeks, including diabetes care startup Beato and D2C health-tech startup Good Health Company.
