About SellTo.us
SellTo.us helps people get a first read on an idea before they spend money on it. You describe a startup idea, app, service, product or ad, and AI-simulated participants built for your audience react to it and explain why.
Why SellTo.us exists
SellTo.us started with a problem its founder knew first-hand. Before building SellTo.us, the founder ran dropshipping stores on Shopify. Testing a new product meant paying for stock and ads first and only then finding out whether anyone cared. Most of that money went into learning what didn’t work.
The question was simple: is there a way to get an early signal before spending? Not proof, which only real customers can give, but a better idea of which products, prices and messages were worth testing with real money, and which objections to expect. SellTo.us is the tool built to answer that question, and it grew from physical products to startup ideas, apps, services and ads.
The problem it solves
Ideas usually get money before they get evidence. Real customer research is the right way to get evidence, but at the earliest stage it can feel slow or expensive, so many people skip it and guess. SellTo.us sits before that step: a fast, low-cost way to narrow down your options, find likely objections and decide what to ask real people first.
Our mission
Help more people test before they spend: make the first check of an idea fast, cheap and honest, and point clearly to the real-world tests that should come next.
What SellTo.us is, and what it isn’t
AI-simulated research
The participants are AI personas built from the audience you describe. Their answers are counted by code and summarized in a report.
Not a human survey
No real people answer. Results are simulated reactions, not survey data, customer research or opinions from a panel.
Not a forecast
Results aren’t sales predictions or conversion rates, and no accuracy is claimed. Use them to decide what to check with real people.
The testing methodology explains how participants are created, how answers are counted and checked, which AI models are used, and the limits. You can see a full example in our sample report.
