Acheul Studio investigates and incubates century-defining innovations across every stack in technology, including frontier AI, anchored in the modeling of human psyches — as profound as what the Acheuleans experienced nearly two million years ago.
We work with industry and academic experts on an ad hoc basis, evolving into co-founding structures when deeper commitment is warranted, and bring ideas to market only when they prove substantially useful for users.
Nobody wants to wear a brick over their eyes — not even with a goggle form at 100 grams. The idea was to radically narrow the experience the device needed to deliver, then radically reduce the sensors and components required to deliver it. Under 100 grams remains, with today's components, an open problem.
Explored down to every component, with engineers who previously led work at Apple, Meta, Google, NVIDIA, Fitbit, and Magic Leap.
Hardware, VR
Waveguide optics has changed the AR landscape — lower cost, lighter weight, finally near consumer-ready. The remaining question is whether the experience inside the glass is compelling enough to justify wearing them at all.
Acheul worked extensively with the Asian supply chain to find a viable path from prototype to mass production, alongside full-time co-founders who joined from Google's AR division (Tech Lead) and the Fitbit / Google hardware team (Staff Mechanical Engineer).
Hardware, AR
People won't accept AR glasses that lock them out of the apps they already live in. So enabling every smartphone application — rendered AR-native rather than ported as flat rectangles — wasn't optional; it was the requirement. We built it. We concluded that it's meaningful, but lacks the gravity of smartphone screens.

OS engineering · Systems · UX
What if, through outward-facing cameras and inward-facing lenses, the world in front of you could be rewritten in real time? What if you could walk through it dressed in your favorite film or game? That was the prototype: off-the-shelf image generation models, aggressively modified for real-time inference. The result opened up an unexpectedly exciting direction for what could become central to human life.

Cyberpunk visionaries have long asked what it would mean for a soul to live inside a machine. Today's AI systems are still far from the philosophical work required to make machine intelligence genuinely human — and to flourish alongside us.
Ongoing research project at Stanford
Once human-grade souls live inside our AI systems, the speed, breadth, and depth of what our society can produce — and meaningfully consume — will look almost unrecognizable from where we stand today.
Ongoing prototyping project at Stanford
Taiga Sawamura was born in Japan and raised in North Carolina and New York. He is based in the San Francisco Bay Area, where he generates in-depth human data and conducts research on it at Stanford.
Taiga has spent more than 15 years modeling human psyches in various domains, including investor and market sentiment, borrower–lender game theory, and generative media consumption.
Taiga co-founded Emerada, a Japanese fintech startup serving over 1,000 banks and one million small and medium enterprises with its financial data aggregation API and AI models. As CEO, Taiga led and helped grow the company to approx. $100M valuation, raising $20M from institutional investors including JAFCO (often dubbed as Japan's Sequoia). Before Emerada, he advised M&A and financing at Goldman Sachs.
After selling his stakes in Emerada, Taiga opened Acheul Studio in the Bay Area in 2024. Since then, Taiga has personally contributed $1M into the studio's projects to date.
