From billions of molecules to experimental hits

Rowan designs and runs the computational screen, coordinates synthesis and assays, and returns measured results your team can act on.

Start with a free target feasibility study.

Design

A unique search process for your target and constraints

We turn your target, prior data, property goals, and chemical constraints into a computational search across billions of synthesizable molecules.

Make

Screen billions of molecules, synthesize the most promising

Physics and ML narrow the search to a focused, diverse set. We work with our synthesis partner, onepot, to make the selected candidates.

Test

Measure what actually works

We coordinate the right assay (with one of our assay partners, your assay partners, or your in-house team) and measure the synthesized candidates against your target.

Analyze

Turn results into the next decision

We connect assay results back to the models, show what worked and why, and recommend the next design cycle.

Virtual screening should end with an experiment

Traditional virtual screening

A file of predicted scores

Your team still has to check synthesis, source compounds, find an assay partner, coordinate testing, and connect the results back to the models.

Rowan virtual screening

Compounds tested against your target

You receive experimental assay data, the computational context behind each compound, and a decision-ready package for the next round.

Predictions met the instrument

Four compounds proposed. Four binders measured.

In a live medicinal-chemistry challenge with muni and onepot, muni's agentic workflow powered by Rowan proposed four compounds. After synthesis and SPR testing, all four showed binding.

The screen fits your science

Build around your program

We tailor each screen to your data and goals, then coordinate testing with your team, your assay partner, or one we help choose.

Search what can actually be made

We identify diverse candidates from onepot's synthesizable chemical space of 30B+ compounds with custom GPU-accelerated docking and ML-based search.

Spend compute where it matters

As the pool narrows, we apply a target-specific ensemble of docking, co-folding, property prediction, and more accurate physics- and ML-based scoring methods.
