The Supplant Company

A brand-new blend of sugars – made from plant fiber!

The Supplant Company is defining a new category of food ingredient: sugars from fiber. Supplant™ sugars from fiber is a brand-new blend of sugars found naturally in plant fiber. With Supplant™ sugars from fiber, your favorite treats can look, feel and taste like they’re supposed to. Because it’s made from fiber, Supplant™ sugars from fiber is lower in calories, has a lower glycemic response (compared to glucose), and is prebiotic. It’s made by upcycling agricultural side-streams. For example, in corn (maize), it’s made from the cob, not the kernel. In wheat and rice, it’s made from the straw, not the grain. These fiber-rich parts of crops are hugely abundant and don’t typically make their way into the food system.

The Synthesis Company

100x faster scientific evidence synthesis

We enable research that was previously impossible—systematic reviews of 20,000+ papers in weeks with 98% accuracy. We collaborate with researchers at Stanford, Harvard, and Johns Hopkins to ask the big questions they've been forced to scale down. Pharma companies get complete evidence awareness in weeks — not years. AI labs get the same reviews as RL environments with expert-validated reasoning traces—scientific synthesis as the next frontier after math and coding benchmarks. We're former DSPy core contributors who built the production infrastructure to make total evidence awareness actually work at scale.

ThirdLayer

Building Dex, the AI Browser Copilot

ThirdLayer is an applied research and product lab building the next interface for human–AI collaboration. Our first product is Dex, an AI copilot for the browser. Think Cursor for knowledge work, optimized for speed and embedded directly where you work. Most web agents are built for set-and-forget tasks. But real work is fluid and messy—spread across tabs, tools, and evolving decisions. Dex transforms your browser into an intelligent, multimodal workspace that understands your intent through voice, text, and action. It enhances familiar interfaces, automates tedious steps, and removes the friction of handoffs. Beneath the surface, Dex is more than a browser agent — it’s a foundation for: ● Long-term, cross-modal memory grounded in real workflows ● A new interaction layer to replace static UI with a collaborative canvas ● Personalization: understanding how individuals approach tasks and navigate software We're building the infrastructure for adaptive, intent-aware systems that work the way you do.

Thread

Thread makes it incredibly easy to dress well, using stylists and AI

Thread, a free online personal styling service for men, uses a combination of human stylists and a powerful algorithm to make it easy for guys to dress well. Thread was founded in 2012 by three guys—Kieran, Ben and Ben—who wanted to dress well, but found it difficult or frustrating to do so: they hated shopping on the High Street and were overwhelmed by millions of choices online. Thread combines the best bits of tech with the best bits of personal styling: After signing up by completing a short questionnaire and uploading photos of yourself, you’re paired with a stylist who reviews your information and uses Thread’s proprietary algorithm to sort through thousands of items to create the best outfits for you. When you log onto Thread, everything you see is tailored to your sizes, budget, preferences and tastes. We’ve raised $16 mm in funding from investors in the realms of tech, Artificial Intelligence and fashion, including Beringea, Balderton Capital, Demis Hassabis and Mustafa Suleyman (co-founders of Google-owned DeepMind), Andrew Jennings (former president of Saks 5th Avenue), Edgar Bronfman Jr. (former owner of Warner Music), Guy Hipwell (former head of online at Harrods and Liberty) and Shakil Kahn (founding investor in Spotify).
