What an extraordinary transformation twelve short months can bring. Only a year ago, during the previous San Francisco Tech Week, OpenAI’s valuation hovered around a comparatively modest $157 billion, and the mood across the technology sector remained uncertain and introspective. Many wondered if the industry had truly shaken off the lingering stagnation that followed the global pandemic — that slow, uneasy period when innovation seemed to pause and investor enthusiasm waned. Today, the landscape could not feel more different. OpenAI has now ascended to a breathtaking valuation of roughly half a trillion dollars, symbolizing not merely a corporate success story but the broader resurgence of technological confidence. Artificial intelligence, once viewed as a promising but still speculative frontier, has firmly entered the mainstream, igniting an unprecedented wave of fascination and fervor among investors and entrepreneurs alike. Across Silicon Valley and beyond, new startups are sprouting at a dizzying pace, each hoping to claim its place in this renaissance of digital creativity. The atmosphere suggests a rekindled optimism — a return to the exuberant spirit that defined earlier eras of innovation — and at the heart of this rejuvenation stands San Francisco, vibrant once more as the pulsing, incandescent nucleus of the global tech ecosystem.
“It’s been a long time since I’ve felt this kind of energy,” observed Gwyneth Borden, the dynamic founder and chief executive of Remynt, a fintech startup riding the current wave of innovation. The coastal wind brushed through her hair as she spoke, standing on the bow of a chartered ferry gliding beneath the majestic spans of the Golden Gate Bridge. The vessel, rented by Menlo Ventures along with a group of other venture firms, had been transformed into a floating salon of conversation and opportunity — a place where the founders of emerging startups mingled freely with seasoned investors, all while watching the U.S. Navy’s Blue Angels practice their aerial acrobatics overhead. Inside the cozy cabins below deck, attendees balanced plates of meatballs and crisp crudités, a modest but cheerful feast amid discussions of capital, growth, and possibility. The event, aptly named “Founders + Funders Cruise: Angels above the Bay,” carried an almost cinematic sense of optimism, emblematic of the broader tone of SF Tech Week 2025.
Although the air show was ultimately cancelled due to the ongoing federal government shutdown, few participants seemed discouraged. Among them was Jerry Shu, the enthusiastic co-founder of Daylit, a Boston-based AI company that had recently secured millions in fresh funding. Leaning against the rail, eyes scanning the distant skyline, Shu radiated a blend of relief and exhilaration. “It’s no longer just buzzwords,” he remarked, reflecting on how rapidly the narrative around AI had shifted. “Last year, there was a lot of talk — big claims, endless demos. But now, you can actually feel the power of these products. The momentum is tangible. Honestly, there’s probably never been a better time to be a founder than right now.” His sentiment echoed across nearly every gathering that week: this was not hype without substance, but a moment of genuine technological transformation, where the promise of AI was manifesting into visible, measurable change.
The revival of SF Tech Week itself tells a story of resilience and reinvention. The event began only a few years earlier, when Andreessen Horowitz – better known by its shorthand, a16z – launched the first iteration in 2022. Initially conceived as both a community gathering and a strategic marketing initiative for the firm, it was modest compared to its sister events in Los Angeles and New York. At the time, San Francisco seemed to be losing its luster; office towers sat half-empty, and headlines portrayed a city in decline. “Many wrote SF off — empty offices, stories of decay,” recalled a16z partner Katia Ameri in an email to attendees at the start of this year’s festival. “Many questioned why we would even hold SF Tech Week at all. And then AI hit escape velocity.” Within two years, the city’s narrative had pivoted dramatically. Companies were once again leasing millions of square feet, rental prices were climbing, and communal hacker houses — those legendary incubators of new ideas — had returned with renewed vigor. The transformation, Ameri implied, was not just economic but cultural: the spark that defines Silicon Valley had reignited.
Now, with over 1,500 separate events taking place across the city, San Francisco’s Tech Week has surpassed its counterparts in size and prestige, evolving into a sprawling festival that celebrates the intersection of creativity, capital, and code. The only lingering question, posed playfully by many locals, is whether the city truly needs a separate week dedicated to technology when, in truth, every week in San Francisco already feels like Tech Week. “Everyone who actually lives here says it feels like any other week,” laughed Amber Trivedi, a San Diego entrepreneur seeking investors for her biotech-aligned startup LifeSpark Labs. “Still, having so many events lined up makes it worth the trip — it’s a chance to meet everyone in the same place, to see what’s next.”
The events themselves ranged from the experimental to the extravagant. One workshop offered participants a chance to experience “robot-yoga,” a whimsical yet thought-provoking exercise that fused movement and machinery, encouraging attendees to reflect on what it means to welcome technology into spaces traditionally grounded in trust, mindfulness, and vulnerability. At the opposite end of the spectrum, a late-night gathering in SoMa promised a curated guest list of founders, venture capitalists, and product builders — those who, as the invitation boasted, “ship fast, love great shows, and aren’t allergic to the dance floor.” The mix of professional ambition and social vibrancy defined the week: serious ideas, serious money, and a dash of revelry.
One of the most anticipated highlights was a16z’s Speedrun Demo Day, a fiercely competitive showcase where 61 selected founders — chosen from an astonishing pool of 14,000 applicants — each had just two minutes to deliver their pitch. “Over ninety percent of the startups presenting this year were heavily focused on AI,” noted Joshua Lu, one of a16z’s investing partners. “We’re living through a technological supercycle.” His observation captured what so many others were sensing: artificial intelligence is no longer a peripheral industry segment but the gravitational center pulling the entire tech universe toward it.
From dawn to well past midnight, conversations across coffee shops, conference halls, and rooftop parties inevitably returned to the same topic: AI. Whether discussed as a transformative tool, an economic engine, or a philosophical challenge, it dominated the week’s discourse with extraordinary force. “It’s a bit of a gold rush right now,” admitted Joanne Chen, general partner at Foundation Capital, offering a thoughtful note of caution amid the euphoria. “One could argue that valuations are climbing too high and that investor enthusiasm borders on overexuberance.” After a contemplative pause, she added, “But people understand — perhaps better than ever — that while there will undoubtedly be many winners in this new era, there will also be many who don’t make it.” Her words served as a gentle reminder: even during the brightest surge of innovation, the line between triumph and turbulence remains thin.
Together, these voices paint a vivid portrait of a city and an industry in motion — cautious yet fearless, reflective yet relentless, grounded in realism but propelled by vision. In San Francisco, once again, the forces of invention and ambition converge, and the rhythm of progress beats louder than ever before.
