Does my data ever leave my workspace?

Your product context, persona library, and run history are isolated per workspace with row-level security. Simulations execute in ephemeral runners and are wiped after synthesis. Atlas tier offers on-prem and VPC swarm runners.

How long does a simulation take?

A 500-agent run typically completes in 8-14 minutes. You watch agents react live in the console. We optimize for parallelism, not single-agent depth.

Can I import my real users?

Yes. Drop a CSV of behavioral cohorts, or pipe Posthog/Amplitude events. Presume builds weighted persona templates that mirror your actual ICP distribution.

Why agents instead of just running more LLM calls?

An LLM gives a model-average opinion. A persona agent — primed with a goal, a history, and a tone — gives you a position. Position × volume × parallelism is what creates a distribution. That distribution is what you need to ship.

Presume

Stop guessing how your users will react.

Presume runs an agent-swarm simulation of your real user base reacting to a product change — before you ship.

Accuracy depends on the quality of your product context and ICP — better inputs, better forecasts. We surface confidence intervals on every run, and we publish calibration data as the corpus accrues. Treat early outputs as directional guidance to inform decisions, not statistical fact.
