Reliable Robotics Lands $115M Series D Extension at $1B+ Valuation to Push Autonomous Flight Toward FAA Certification

SpaceX-alumni-founded Reliable Robotics closed $115M in equity plus $25M in debt as a Series D extension led by Nimble Partners, lifting its valuation past $1B and total raised to $380M.
