Momentum Machines, a US-based, food industry-focused robotics technology developer that counts internet technology group Alphabet as an investor, has raised $18.4m in new funding, according to a regulatory filing.
The company has not disclosed the identities of the 18 investors in the round, but the filing indicates it intends to close it at $22m.
Founded in 2009, Momentum has built a robot that can prepare and grill burgers rapidly and autonomously, with preferences for individual users programmable into the system.
Momentum is still operating in stealth for the most part, but has applied for a permit to open a restaurant in San Francisco.
Although the company has not officially revealed details of earlier funding, securities filings indicate it raised approximately $350,000 in equity and debt in 2013.
Axios has reported that Momentum’s existing investors include Alphabet’s GV subsidiary as well as Khosla Ventures, K5 Ventures and Lemnos Labs.
