STEP / 01
Design in the cloud
Create formulation experiments with AI guidance tailored to your molecule and goals. Our system converts those designs into fully executable workflows and runs them in our robotic lab — no infrastructure required.
Cloud Lab
Run our robotic formulation lab. Remotely.
Through our web interface, your team can choose formulation parameters, and our robotic lab will build and test the formulations. All data is available through the cloud portal.

STEP / 02
Our robotic lab runs your formulation
Through integrated scheduling software and automated hardware, the platform executes experiments — overnight runs, weekend campaigns, and real-time monitoring all included.
STEP / 03
Analyze results in your dashboard
Access structured experimental data as soon as runs are complete. Every result is automatically captured, organized, and delivered to your dashboard — ready for analysis, comparison, and iteration.
Screenshots are from our actual platform. Data shown is for illustrative purposes only.
IP PROTECTION
Worried about IP? We understand.
Persist retains no formulation IP; under our MSA, all formulation IP and commercialization rights belong entirely to you, with no hidden fees or royalties.
Step 1
Sign an MTA
Any intellectual property related to the formulation or drug will be assigned to you.
Step 2
Send the substance
We'll store the drug, determine solubility, and onboard it onto our automation.
Step 3
Begin formulating
Once the drug is onboarded, you can start requesting formulation tests for the cloud lab to execute.
Cloud Lab is a robotic formulation lab that customers operate remotely. You design experiments through Persist's web platform with control over formulation parameters, and our robotic lab executes the experiments and streams results to a cloud dashboard.
The Cloud Lab supports formulation screening across ASDs, SEDDS, microspheres, in-situ depots, parenterals, and topical formulations. Common workflows include solubility studies, stability assays, dissolution profiling, polymer-API compatibility, and excipient screening.
Most screening campaigns return results within days rather than weeks. Persist's high-throughput robotic lab parallelizes formulation candidates that would take a manual team weeks to execute.
No. Cloud Lab is fully remote — Persist owns and operates the robotic lab. You design experiments in the browser, and Persist handles execution, sample handling, and data capture.
All formulations and experimental data are confidential to the customer. Persist operates under standard pharmaceutical confidentiality agreements and does not use customer IP to train shared models.
