Caltrain
Caltrain’s Diridon Station Steering Committee has hired Bill Sirois as the Director to lead the implementation of the Diridon Station Program, which is expected to “transform and modernize San Jose Diridon Station to enable future growth and mark its significance as a major regional transit hub in the statewide rail network, as well as support the transit-oriented expansion and growth of downtown San Jose.” The program is being led by a partnership of five agencies: Caltrain, the city of San Jose, the Santa Clara Valley Transportation Authority (VTA), the California High-Speed Rail Authority (CHSRA), and the Metropolitan Transportation Commission (MTC).
Sirois will serve a three-year term in the position, where he is charged with advancing the program through environmental review. He will lead the program team, as well as set up a long-term governance entity that will ultimately deliver the program and obtain funding for the next phases of work.
Sirois will report to the Diridon Station Steering Committee comprised of voting members from the five partner agencies and ex officio member Rod Diridon Sr. and a Bay Area Rapid Transit (BART) representative.
Sirois spent more than 20 years at the Regional Transportation District (RTD) in Denver, and was instrumental in advancing the Denver Union Station project, which has been built and is operating. The project is nationally recognized as a marquee of what future transit stations should be.
“Caltrain and its partners are investing in more than a transportation hub; Diridon will be a catalyst for regional connectivity and growth,” said Caltrain Board Member and Santa Clara County Supervisor Margaret Abe-Koga. “This project will deliver lasting benefits for the city of San José, Santa Clara County, and the Bay Area as a whole.”
“I’ve had a lot of personal experience in that area [Denver Union Station] and just seeing the renaissance of that particular area, pulling in the sport franchises, private sector, retail, is commensurate of what we want for Diridon,” said Diridon Steering Committee Chair and San Jose Councilmember Michael Mulcahy. “I’m excited to have unanimous approval for someone that has had experience directly applicable to our project.”
Duos
Duos has appointed Doug Recker as CEO, effective April 1, 2026, as the company “accelerates its transformation into a focused Edge AI and digital infrastructure platform.”
Recker succeeds Chuck Ferry, who will continue to serve as a member of the Board of Directors. He will lead Duos’ next phase of growth focused on “scaling modular EDCs, expanding GPU hosting capabilities, and executing a disciplined capacity expansion strategy.”
Under Recker’s leadership, Duos and its operating subsidiaries, including Duos Edge AI, Inc., are entering into a commercial partnership with Hydra Host to provide GPU hosting and GPU-as-a-Service solutions. The partnership includes structured hardware financing arrangements designed to “accelerate deployment and support growing demand for distributed AI compute.”
“We are thrilled to partner with the Duos team on this opportunity,” said Aaron Ginn, CEO & Co-Founder of Hydra Host. “Their ability to deliver immediate access to power combined with an industry-leading deployment speed makes them a standout in the market. We see significant runway ahead as we look to expand our collaboration around colocation and Duos’ High-Power EDC model, which we believe is purpose-built to address a market where demand for AI compute capacity is fundamentally outpacing the speed at which traditional data center supply can be delivered.”
“This initial customer marks a pivotal step in accelerating the buildout of Duos Edge AI and strengthens our ability to execute on our distributed infrastructure strategy,” said Recker. “We are now entering an exciting phase of execution, further reinforced by our recently announced LOI with Hydra Host, which underscores growing third-party demand for our distributed AI infrastructure model and validates the scalability of our platform. With secured power, rapid deployment capabilities, and expanding strategic partnerships, we believe Duos is well positioned to pursue high-value infrastructure opportunities. Our focus remains on disciplined expansion, capital-efficient growth, and delivering sustainable long-term value for our shareholders.”
