Find the rooms your customer is already in.
We tell you where the people you want are actually talking, what they complain about in their own words, and how to show up there without getting thrown out.
Then you post it. From your account. Under your name.

The problem, as somebody put it
Spent half a year building a product and launching it and tried to just post a white paper on HN and Reddit to get some feedback: instant ban for self promotion. From what I've seen, it is not even clear that humans are involved in this process. So how should I proceed? Start paying for ads?
Hacker News, July 2026
The replies told him to buy an aged account with karma, or to do what one of them called shadow marketing.
That is the market's default answer, and it is the reason this exists. If you don't want to buy a fake account to talk to your own customers, your remaining option is to do it properly by hand — which is slow, and which nobody has time for while also building the thing.
What you actually get
Four things, delivered by a person and not a dashboard. The first two are the $500 verdict; all four are the two-week engagement.
- A ranked map of the rooms. Which platforms and which specific communities your customer is actually in — forums, Q&A sites, Discourse instances, subreddits, groups. Ranked by how alive they are, not by how big they claim to be. Most of the good ones are not the obvious ones.
- Each room's rules on self-promotion, extracted and read. Including the unwritten ones and the ratio each place actually tolerates, so you know your budget before you spend it rather than after you're banned.
- Twenty real objections, quoted, linked and dated. What people in your market already say is wrong with things like yours — in their words, not paraphrased into marketing copy. This is the part that changes what you build, not just how you sell it.
- We sit with you while you post. You write it, in your voice, from your account. We tell you what will land and what will get you removed. You keep the relationship, the reputation and the account.
What we will not do, and it's the whole point
- No posting on your behalf. Not by a bot, not by us.
- No aged, purchased or high-karma accounts. Competitors sell these. It works until it doesn't, and when it stops working the platform bans the account and often the website it links to.
- No personas, no sock puppets, no generated enthusiasm. One real person — you — under one real name.
- No pretending a model can write this for you. We tested it against real threads. The comments that earn their place are the ones carrying a specific, first-hand detail nobody could invent. You have those. Software doesn't.
What it costs
Reachability verdict — $500
Two days. The ranked map of rooms, and what each one actually permits. Which answers the question underneath both: is your customer reachable in public at all, and where.
Full engagement — $1,500
Two weeks. All four, including the twenty quoted objections and a person sitting with you while you post. Worth buying once the verdict comes back positive — and a waste of money before it does.
Fixed scope, fixed price, both of them. Sometimes the verdict is no — not in public, not anywhere we can read. You get that in writing too, and it is the cheapest bad news you will buy this year.
Why the cheap one first
Because the answer is not always yes, and finding out costs a fraction of acting on the assumption.
The same tooling ran against two audiences in the same week, on the same free public sources. For a niche trade — California balcony-inspection providers — it found zero verbatim matches for the phrases that trade uses, across the whole of Hacker News, and only 2 of 12 candidate forums were even measurable. For founders with no distribution, it found those phrases thousands of times, and 10 of 16 forums ranked cleanly.
Nobody typed either result in. Same week, same method, same constraints — and the two audiences differ by four orders of magnitude. If yours is the first kind, a two-week engagement is the wrong purchase and I would rather tell you that on day two for $500 than on day fourteen for $1,500. I'll walk you through both runs, live, on a call.
Platform-agnostic, on purpose
Platforms close. Reddit priced out its API, Facebook retired Groups access, Substack forbids crawling outright. Anything built on one platform is one policy change from being worthless.
So the first question we answer isn't how do we win Reddit. It's which rooms are worth your time at all — and that answer is usually spread across places you haven't heard of. There are more than twenty thousand independent community forums that are open, active, and unclaimed by anyone selling to the people in them.
Who this is for
A good fit
- Pre-launch or just-launched, no audience yet
- You know roughly who the customer is, not where they are
- You'd rather be told your idea is wrong now than in six months
- You will post under your own name
A bad fit
- You want volume, automation or scale today
- You want someone else to be the voice
- You need attribution dashboards before you have traffic
- You're a brand protecting share of voice — you want enterprise social listening, and it exists
Being honest about the stage
This is new. There is no customer list to show you, and inventing one would be exactly the behaviour this whole thing is against. Nobody outside my own circle has paid for this yet. You would be first, and you should price that in.
What there is: a lot of primary research into where these communities are and what gets people banned in them, and two engagements run end to end. The first was Nuvea, our own product — aimed at California balcony-inspection providers, though its homepage still says US remodeling contractors, and that gap is itself one of the findings. The second was this: the method turned on its own audience, which is how the comparison above exists.
There were two free places. Both went to products I own or a friend's, which taught me how to deliver the work and precisely nothing about what it is worth. So the free places are closed. $500 is the ask, and the reason it isn't $0 is that a yes costing nothing tells neither of us anything.
Start with a reachability verdict
Tell me what you're building and who you think the customer is. You get a workspace immediately — sign in with the same address and it's there, empty, waiting for the research. Then I reply with the specific rooms I'd start with and what the two days would cover, before you pay anything. If I don't think your customer is reachable, I'll say so in that reply and there is nothing to buy.
Terms, stated plainly. $500 for the two-day verdict, invoiced after we've agreed it's worth doing, not before. If it comes back saying your customer isn't reachable in public, that is the deliverable and it still costs $500 — that is the deal, and it is the honest version of it. $1,500 for the full two weeks, only if you want it afterwards. I'll sign a mutual one-page NDA covering your product and your data. In exchange I ask to write up what happened, named or anonymised, with your approval before anything is published.
