The platform uses its SAPIENS behavior model to construct audiences from demographic, psychological and behavioral information. Vectorial describes using panel data, observed choices, transactions, public information and data partners to build those models. Teams can work with groups of modeled users rather than a single persona answering every question.
A team defines its target audience and the experience it wants to test. Simulations can examine a product journey, a prototype, a landing page, a campaign or a customer-facing AI agent. The aim is to explore how different users might respond before releasing a change to real customers.

Vectorial describes survey and focus-group simulation alongside creative, chat and interface testing. Its product history also lists Figma, landing-page and A/B testing capabilities. These are ways of studying modeled responses; they do not turn simulated participants into a sample of people recruited for a new survey.
Clients can supply survey waves, segment definitions, support transcripts, product analytics and other customer information to fit an audience to their own market. Vectorial describes checking a model against an earlier client study held back from the fitting process before using it for new questions.
The homepage reports 87% accuracy across held-out studies and separately describes matching people's opinions in a comparison with language models. Vectorial explicitly distinguishes those measures. Their meaning depends on the task and scoring method; the homepage figure is not a measured success rate for every product, audience or commercial outcome.
Access is through a company demo; the website also advertises a waitlist. A complete public subscription tariff is not listed. Vectorial announced a $3 million seed round on 20 October 2026 to expand its behavioral datasets and model development. The announcement did not disclose recurring revenue, profitability or a valuation.
