Another former Uber executive is joining Travis Kalanick’s robotics and industrial AI startup Atoms, just a few weeks after it raised $1.7 billion.

Gautam Gupta, the former finance chief under Kalanick, said in social media posts on Wednesday that he has has joined Atoms as chief financial officer. Gupta spent more than four years at Uber until he left in July 2017, just a few weeks after Kalanick resigned as CEO. (Gupta had announced his intention to leave that May.)

Hiring Gupta continues a trend of Kalanick getting the Uber band back together at Atoms. Earlier this year, Atoms acquired mining autonomy startup Pronto, which is run by former Uber (and former Google) self-driving engineer Anthony Levandowski. According to LinkedIn, a number of former top Uber employees who worked with Kalanick also work at Atoms, which was previously called CloudKitchens.

“On many levels, this round is a bit of unfinished business. Fuel to complete the bits-to-atoms story arc we started at Uber, continued at CloudKitchens, and will now finish at Atoms,” Kalanick wrote when he announced the $1.7 billion funding round last month.

Uber even joined the round as an investor, reuniting the company with the founder it pushed out in 2017 after a series of scandals and complaints of widespread sexual harassment and discrimination. Uber hasn’t disclosed how much it contributed. The Information reported $100 million, a figure that TechCrunch has also been able to confirm.
