Apptronik, the Austin-based humanoid robotics startup that spun out of the University of Texas, has closed a $520 million extension to its Series A round, bringing total Series A funding to over $935 million and the company’s valuation to roughly $5.5 billion - triple what it was a year ago.
The money will go toward ramping production of the company’s Apollo robot and building new training facilities, as Apptronik races to get humanoid workers into factories and warehouses ahead of Tesla’s Optimus and a growing wave of Chinese competitors.
Who’s Backing the Bet
The extension round drew a mix of tech giants, industrial heavyweights, and sovereign wealth. Existing investors Google, Mercedes-Benz, B Capital, and PEAK6 doubled down, while AT&T Ventures, John Deere, and Qatar Investment Authority (QIA) came in as new backers.
The investor list reads like a customer wish list for humanoid robots. Google’s involvement runs deeper than a check - Apptronik has a strategic partnership with Google DeepMind to build next-generation robots powered by Gemini Robotics. Mercedes-Benz and logistics giant GXO are already deploying Apollo in real facilities. John Deere’s entry signals agricultural applications could be next.
“Today’s investment is a strong vote of confidence in our mission to deliver humanoid robots that are designed to work alongside humans, not just as tools but as trusted collaborators,” CEO Jeff Cardenas said.
What Apollo Actually Does
Apollo is designed for the kind of repetitive, physically demanding work that’s hard to staff: transporting components on manufacturing lines, sorting packages in warehouses, kitting orders for shipment. The robot works alongside human employees rather than replacing them outright - at least for now.
The company has partnerships with Mercedes-Benz, GXO Logistics, and contract manufacturer Jabil, with pilots already running in their facilities. A new version of Apollo is set to debut later this year.
Apptronik has about 300 employees and a pedigree that includes building 15 previous robots, among them NASA’s Valkyrie humanoid. That engineering depth is part of what investors are buying - the company isn’t starting from scratch.
The Race Is On
The humanoid robotics sector is attracting record capital as companies bet that general-purpose robots will eventually handle a massive share of physical labor. Apptronik’s nearly $1 billion haul is part of a broader funding surge that includes competitors like Figure, 1X Technologies, and a rapidly growing field of Chinese robotics startups.
Tesla’s Optimus program looms large over the market, though Elon Musk’s timeline promises for humanoid robots have been as reliable as his self-driving predictions. Chinese firms, benefiting from cheaper manufacturing and aggressive government support, represent a more immediate competitive threat.
Apptronik’s strategy is to win on partnerships and enterprise trust rather than trying to out-manufacture everyone. Having Google DeepMind powering the brains and Mercedes-Benz as both investor and customer gives it credibility that pure-play robotics startups lack.
What to Watch
The real test comes when Apollo moves from pilot deployments to volume production. Building a few robots that work in controlled settings is one thing. Manufacturing thousands that perform reliably across different facilities is something else entirely.
With nearly $1 billion in the bank, Apptronik has the runway to find out. The next milestone is the new Apollo model later this year - and whether the company can convert its impressive investor roster into paying customers at scale.
