One paper. We don't publish often.
We publish three or four technical papers a year — when there's an experiment worth writing down. This is the first.

Developing Foundation Models for Real-World Tabular Data.
Authors
Marta Garnelo, Wojciech Marian Czarnecki
Length

Reading time

The technical foundation underneath NEXUS. A defense of why tabular data — the most common form of enterprise data — needs its own foundation model, not a fine-tuned LLM. With architecture details, evaluation methodology against 412 real-world datasets, and a frank section on where the approach still falls short.

We're hiring across the stack -- research, infra, applied. The bar is high but the ceiling is higher. If you want to ship models that get used by every Fortune 500 in the next 24 months, talk to us.
Reminder that tabular covers 80% of enterprise AI workloads -- fraud, churn, pricing, claims, ops. LLMs do not solve these. They never did. We built LTMs because the work was sitting there... unfinished.
