Need one more Surdatics Report this month? Add one from your organisation’s wallet, on any plan. It is used only once your plan’s own Reports run out.
No. Start free and pay monthly. One payment covers 30 days, and nothing renews automatically. Enterprise is the only plan with a contract.
Each plan includes a number of responses for every 30 days from the people you reach yourself: your study links and invitations, Quick Feedback answers, votes and offline interviews. Paid answers from Surdatics verified people never count. When you reach the limit, new responses pause until your next 30 days begin, or until you move up a plan.
You set a budget for each approved answer and how many people you need. The cost summary shows what each person receives, and the total, before you pay. Their answers never count toward your plan’s responses, and people screened out earn nothing. A rejected answer earns nothing, and unspent rewards return to your organisation’s wallet when the study ends.
No. You set and fund each study’s rewards when you launch it. The reward each person sees is the reward they receive, and our share comes out of your budget, never on top.
A rejected answer earns no reward. Its reward stays in your study for the next approved answer, and anything unspent returns to your organisation’s wallet when the study ends.
A free survey rewards no one: you share its link with your own people, and its answers count toward your plan. A paid survey rewards each person who answers, and can be shown to verified people on Surdatics.
A free survey is private: only people you share the link with. A paid survey is Public, listed on Surdatics for everyone to see, or Private, for people with the link. Switch any time on the study page.
Plans: by card, bank transfer or USSD at checkout, or by invoice. Study rewards: add funds to your organisation’s wallet by card or stablecoin. You see the exact amount and the currency before you pay. If that is not your card’s currency, your bank may add a conversion fee.
Yes. Change plan from Plan and billing in your dashboard. A new plan starts as soon as payment is confirmed, with a fresh 30 days. Days left on your current plan are not carried over. To stop, simply do not pay again.
Your organisation moves to the Free plan’s limits. Your studies and data stay.
Not today. Every plan is monthly.
Yes. Universities, schools, students and registered non-profits get 30% off plans, after a quick check. It lasts twelve months, and rewards are not discounted. Ask from Plan and billing in your dashboard.
Surdatics keeps a share of each sale. When the data was collected here, the people whose answers are in it share in the sale too, if they agreed to resale. Until checkout opens, prices are on request.
So every rewarded answer comes from one real person. Anyone can see a public study. Verifying takes about a minute, once.
You choose what each person gets; the minimum is $1 an answer, and there is no maximum. As a guide, about $0.20 for each minute your survey takes. Our fee gets smaller as your plan grows: $1.00 to a person costs you $1.40 on Free, $1.33 on Researcher, $1.28 on Team, $1.24 on Scale and $1.20 on Enterprise.
The Free plan drafts studies with Surdatics AI, collects 25 responses a month and anchors every answer on the blockchain. Move up when you need more.
