IrisGo, a US startup building a “digital butler” for PC users, has closed a US$2.8 million seed round led by Andrew Ng’s AI Fund, the startup confirmed to Tech in Asia last week. The company is valued at US$21 million.

Jeffrey Lai, IrisGo’s co-founder and CEO, says he’s already in talks with new investors for a potential series A round of around US$20 million. The company hasn’t set any specific timeline for the series A, though it expects June “to be a good candidate.”
