Short, honest answers. If yours isn’t here, email hello@kasspian.com.
Kasspian finds where your first customers are already asking for what you sell, and writes the reply. It reads the rooms your buyers post in, tells you which ones will actually let you speak, picks the threads worth answering this week, and drafts the answer in your voice. Then it watches those threads and tells you when somebody replies to you.
Three kinds of people. A founder going from a hunch to their first paying customers. An agency or consultant running this for a client's book. A business with revenue and nobody with time to sit in forums. Not a cheerleader, not a lecture.
You paste your site or describe the business in a line. Kasspian reads it, works out who the buyer is, and searches for the places they are already posting: subreddits, forums, communities, live threads. Every place comes back with a real URL and a read on whether you can post there, comment there, or neither. Then it drafts the reply for the threads worth answering.
Because half the rooms full of your buyers will not let you speak, and most tools will happily send you into them. Some remove links from newer accounts, some remove posts on sight, and the removal is rarely announced. Every place Kasspian gives you carries a read on posting and commenting separately, because commenting is usually the open door when posting is shut.
Yes, and it is the front door rather than the point. Write the idea in plain English and Kasspian scores it across market size, demand signal, risk and competition, then gives you a one-sentence call: build it, change it, or kill it. The full report breaks down the reasoning so you can argue with it. Most people come for the customers and use the read once.
The call is an opinion, not an oracle. Kasspian is right enough of the time to save you weeks of building the wrong thing, and we tell you when it is not confident. Treat it like a smart advisor's first take, not a judge's ruling.
A chatbot can write you a reply. It cannot tell you which room will delete it. Kasspian reads the rooms from the outside, where the rules and the removals are visible, and it keeps watching the thread after you post. It also gives you the call including the no, on the same rubric every time, where a general chatbot wants to be helpful and leans toward yes.
Push back. Open Ask Kasspian on the report page and argue your case: bring numbers, customer interviews, anything. Kasspian will either change its mind with new info or hold firm and tell you exactly why.
About three minutes for a full read. Kasspian searches the live web while you wait, then hands you something you can act on in one sitting.
Kasspian has free, no-signup tools: an idea validator, a competitor check, a website conversion checker, and a marketing channel finder, plus calculators for market size (TAM/SAM/SOM), startup runway, cofounder equity, and your riskiest assumption. Each gives a real answer instantly. See them all at kasspian.com/tools.
Two get-customers plans and two idea reads, plus two credits, no card. They are lifetime rather than monthly, so nothing expires while you decide. Every free tool stays free and needs no account at all.
A credit adds live web sources, meaning real cited market data, to a single idea read. New accounts get two. After that you buy a small top-up, or go Pro for unlimited sourced reads. Credits never expire.
Free is two plans and two idea reads, no card. Pro ($19/month, or $15/month billed annually) writes your outreach ready to send, finds three new rooms a week with two of them written, tracks every lead you send, and makes every idea read sourced with live web data, plus competitor and market deep-dives and a watermark-free PDF. Agency ($299/month) is for people running this for clients: every client gets their own plan and their own weekly rooms with the outreach written. That one is set up on a call, so email hello@kasspian.com rather than checking out.
No. Sign up free and you get two plans and two idea reads with no card, and the free tools need no account at all. A card only enters the picture when you want Kasspian writing your outreach every week.
If you bought credits and have not used them, yes, within 14 days of purchase. Subscriptions can be cancelled any time and you keep access until the period ends. Email hello@kasspian.com.
Kasspian keeps reading your rooms after the first plan. It emails you when it finds a new thread worth answering, when somebody replies to something you posted, and when the market moves in a way that changes your odds.
