A senior attorney at Airbnb has resigned to become the chief legal officer of the New York City-based fintech startup Rho.

Alexa Summer announced the move on LinkedIn. She had been San Francisco-based Airbnb's lead counsel for risk and regulatory for four years. Before that, she worked for the Justice Department and in private practice at Cotchett, Pitre & McCarthy, K&L Gates, and Morrison & Foerster.

Rho operates a spending and cash management platform for smaller businesses that boasts frictionless workflows across banking, cards and accounts payable. The company, which launched in 2018. raised $75 million in funding in December, bringing its funding to $205 million.

In her LinkedIn post, Summer thanked mentors and supporters who helped to bring her to this point in her career.

"I can't tell you how grateful I am for your thoughtful advice, and for the knowledge that you're always there for me as a resource. This includes my family: I am so lucky to have you, supporting me and letting me support you in return," she said.

"Now, on to great work!" she added. "I'm proud to be a female executive and will continue to champion inclusion and diversity efforts."
