Many Body
Data for scientific AI
AI for Science · data layer

High-accuracy data for models that understand matter.

Many Body generates high-accuracy molecular and materials datasets so that pharma, materials, and chemicals teams can train scientific foundation models that reflect real electronic behavior.

We generate the data your models wish they were trained on.
What Many Body provides

We generate and curate structured molecular and materials data at electronic-structure accuracy, then package it so it slots into real ML pipelines.

Data sets
Off-the-shelf training data
Large, ready-made datasets of high-accuracy energies, forces and electronic descriptors across broad chemical spaces, designed for pre-training and fine-tuning rather than any single molecule.
Molecules & complexes Materials & surfaces Reactivity regimes
On-demand
High-accuracy for key candidates
You send us a small set of high-value molecules or structures; we return reference-grade binding, stability and reactivity values to benchmark your models and de-risk important decisions.
Binding & stability Reaction profiles Interfaces & defects
Co-design
Custom data curricula
We work with a small number of partners to design and generate tailored datasets, choosing the chemistries and accuracy that best match their domain, assays and model architectures.

The missing data layer in Scientific AI
The Many-Body Systems Manifesto

Scientific AI is advancing, but progress is uneven. Most success occurs where physics is smooth and approximations behave predictably. The hardest regimes, where collective electronic behavior and many-body interactions dominate, remain underexplored. These are also the regimes with the highest scientific and economic value.

Today’s models inherit the limitations of their training data. DFT reshaped computational science, but what began as an approximation gradually became treated as ground truth. Learning systems trained on this data reproduce its behavior, including its blind spots.

Scientific AI does not suffer from a lack of data volume. It suffers from a lack of coverage. What is required is reference-grade, post-approximation data that captures true electronic behavior where it matters most.

Many Body exists to build this missing data layer.

If this sounds like you, we should talk

Many Body is for teams already serious about AI for Science, and who think the next edge will come from their data, not just their model size.

  • You’re training, or planning to train, a molecular or materials foundation model.
  • You see your models fail on edge-cases or chemistries dominated by strong correlation, metal coordination, or non-ground-state effects
  • You want a clean way to bring higher-accuracy physics into your training and evaluation loop.
Typical collaborators

Examples of teams we support:

· Pharma / biotech building generative models for small molecules or biologics.
· Materials & battery teams optimising stability, transport, or interfaces.
· Industrial chemistry groups working on catalysts, process conditions, or surface phenomena.

If you’re somewhere on that map, we’d be happy to explore where high-fidelity data could move the needle for your applications.
