El Dorado Hills headquarters gives way to Silicon Valley
A technology company with roots in El Dorado County appears to have moved its corporate headquarters out of the region, marking a notable change for one of the area’s homegrown artificial intelligence businesses.
Blaize Holdings Inc., which develops specialized AI processors and computing platforms, now identifies San Jose as its headquarters and principal executive office.
The change is documented in a Form 8-K filed Nov. 5 with the U.S. Securities and Exchange Commission (SEC). The filing lists the company’s new principal executive office at 2890 Zanker Road, Suite 107, San Jose, California, 95134. It also identifies the former address as 4659 Golden Foothill Parkway, Suite 206, El Dorado Hills.
The distinction is significant. Earlier corporate filings continued to identify El Dorado Hills as the company’s headquarters, including its financial reporting for the second quarter of 2026.
Blaize’s November filing and accompanying corporate announcement now identify San Jose as its headquarters. The company has not publicly detailed the circumstances surrounding the relocation or explained whether employees or other operations will remain in El Dorado Hills.
From El Dorado Hills to the AI industry
Blaize traces its beginnings to 2010, when the business was incorporated as ThinCI Inc. The company subsequently adopted the Blaize name in 2019.
Its technology focuses on artificial intelligence processing at the network edge — allowing devices and systems to analyze information closer to where data is collected rather than relying entirely on centralized cloud computing.
The company’s applications include computer vision, industrial automation, smart cities, telecommunications, retail and other technology-driven operations.
Blaize became publicly traded following a business combination completed in January 2025. Its common stock trades on the Nasdaq under the ticker symbol BZAI.
For El Dorado County, the company’s departure from its longtime headquarters represents another change in the region’s business landscape. Whether the relocation will have a measurable local employment or economic impact remains unclear.
New CFO will also oversee company operations
The headquarters change is not the only significant development disclosed in the company’s latest filings.
Blaize appointed Martin Costas as its new chief financial officer and chief operating officer, effective Nov. 2, 2026. He succeeds Harminder Sehmi, who is retiring from the CFO position.
According to the SEC filing, Sehmi notified the company of his retirement decision Oct. 30. He will remain with Blaize through Nov. 30 to assist with the transition.
Costas brings more than 25 years of financial and operational leadership experience. His previous positions include CFO at BOXABL Inc., Honeywell Process Solutions and Nexans AmerCable. He also held senior financial positions at Sysco and Schlumberger.
Costas will report directly to Blaize CEO Dinakar Munagala.
Announcing the appointment, Munagala said:
“Martin brings extensive public-company financial leadership, capital markets experience and operational expertise to Blaize at an important time for our business.”
Munagala added that Costas’ experience would help the company strengthen its financial position, improve operational efficiency and pursue commercial opportunities.
A $425,000 salary and financing-based incentives
The SEC filing also provides details of Costas’ compensation package.
His annual base salary is $425,000, with eligibility for an additional bonus targeted at 50% of his base salary, or $212,500.
The bonus is tied to financing milestones. Half of the target bonus is linked to the company receiving $10 million in net proceeds from qualifying financing by Dec. 31, 2026. The remaining half is tied to receiving $50 million in net proceeds between Jan. 1 and June 30, 2027. Payments can be prorated if the company raises less than the specified targets.
His employment agreement also includes stock options tied to continued service and company performance, including an award contingent on Blaize achieving and maintaining a market capitalization of at least $500 million for 60 consecutive days.
These provisions place particular emphasis on financing and operational performance as Costas assumes responsibility for both the company’s financial and operating organizations.
What the move means for El Dorado County
The relocation raises questions about the future of Blaize’s local presence and whether any portion of its operations, workforce or business infrastructure will remain in El Dorado Hills.
The available SEC disclosures establish that the company’s listed headquarters and principal executive office have changed. They do not, by themselves, establish that every local operation or employee has relocated.
For a county that has long sought to attract and retain technology-oriented businesses, the distinction is worth watching.
Blaize’s story began in El Dorado Hills in 2010. Sixteen years later, its corporate address points to San Jose and the heart of Silicon Valley.
The company has not publicly provided a detailed explanation for the headquarters change, leaving unanswered questions about the timing of the move and its implications for El Dorado County.
