When GVS moved from Brannan Street to the corner of Fremont & Harrison, the building was old, industrial, and raw. It had the bones of a working San Francisco machine shop: heavy structure, concrete, steel, wood, overhead crane elements, old belt-driven mechanical character, high ceilings, and the kind of volume and natural light that is almost impossible to recreate in a modern office tower.

Over the decades, GVS improved the building phase by phase. What began as an aging industrial property became a creative technical headquarters — a place where engineering, storage systems, media technology, clients, and international visitors all passed through. For years, the building helped introduce GVS customers and partners to San Francisco.

At the same time, the neighborhood changed dramatically. The East Cut and Rincon Hill grew up around 390 Fremont. Towers rose. Traffic patterns changed. The skyline shifted. Yet the building remained a rare standalone presence at one of the city's most visible intersections.

That is what makes the property unusual today. It is not simply a vacancy or a typical office listing. It is a building with history, infrastructure, identity, and street-level visibility.

Over the years, GVS has introduced more than 100 products to the market and developed some of its most innovative systems inside this building, including the GVS 9000 product line. Working with Apple in the early 1990s — incorporating their motherboards and CPUs into our own systems — was one of the earliest chapters. What came after mattered more.

From this building, Grande Vitesse Systems has delivered mission-critical technology to space agencies, defense programs, broadcast networks, research universities, and global brands. Work that had to perform the first time, every time — engineered, built, and tested here at Fremont & Harrison.

In a public Navy solicitation, the Naval Undersea Warfare Center at Newport named Grande Vitesse Systems the only known source for the GVS9000 2U server — stating plainly that no alternative specifications would be accepted.

The orders themselves tell the story: customized dual-processor GVS9000 2U servers, Nomadic drive bays with drive carriers — and custom drive-mount screws specified down to the part number, ordered by the hundreds. Procurement recurred over years as systems were sustained in the field.

That is what engineering to a client's constraints actually looks like. When a system has to drop into equipment already in service, tolerances are not negotiable — right down to the screws. GVS products were never speculative. Every line began with a customer's problem and was engineered from scratch to solve it.

Along the way the shop produced genuine firsts, including the first redundant power supply built into a 1U rackmount Mac — something no one had done before. More on the product lines at gvs9000.com.

That kind of work does not happen in ordinary space. It happens in a place with volume, light, power, flexibility, and character. This building gave us the room to think, build, test, host clients, improve products, and bring people from around the world into San Francisco.

When the 400-ft tower at 340 Fremont was being built, the project needed something unusual: room to work, and a structurally sound neighbor willing to help. Grande Vitesse gave up a portion of our own office space and let critical shoring support run through our building — and our structural engineers supervised and monitored the entire operation to make sure it would not compromise our property.

The result: a major high-rise that went up safely and remarkably on time. To this day, we still have some of the seismic markers in our building from that work — a permanent, physical record of the role 390 Fremont played in shaping the modern East Cut.

Everything Grande Vitesse built came out of this building. Hundreds of products over three decades — designed from the ground up, assembled, built, tested, installed, and supported around the clock, all from one address in San Francisco. For a small company to do that, and still be here, the space itself deserves a share of the credit.

It could not have happened under a nine-foot ceiling. Not in a box on the floor of a tower — not even in a corner office with a gorgeous view. What this building gave us was room: volume, light, and the space to think in.

It also gave us independence. We came in when the work called for it and stayed as long as it took. No one monitored the door. No interruptions — just the ability to concentrate, and to keep concentrating, for as long as an idea deserved. That freedom is the reason the hard problems got solved here.

Put today's tools in the hands of a team, and then give them a building that gets out of the way and lets them think — that is a genuinely rare combination in San Francisco.

It matters commercially, too. In an era when companies are struggling to bring people back to the office, you have to offer more than another tower floor. People return for a place with character — a space they're proud to walk into, where the work feels like it belongs. This building has never had trouble being that.

That is why we are being thoughtful about who comes next. We have had strong interest in the building over the years — including serious offers and tenants willing to move quickly — but the character of this structure is exactly what makes it rare. Rather than see that character lost, we would rather see it carried forward.

The right company could thrive here the same way GVS did. And GVS isn't going anywhere — our R&D remains rooted in this building. We're simply opening a part of it to a company that sees it the way we always have.
