How to find one potential customer in 24 hours
A repeatable way to find a real potential customer for any startup in a day: find the problem in public, pick the channel, write the first line.

Last week I posted an offer in r/Startup_Ideas: send me your startup and within 24 hours I will find one person who is actively showing signs that they need what you sell. Not a name scraped from a database. Someone discussing the problem, asking for recommendations, comparing options, or engaging with a product like yours.
I limited it to five businesses so I could research each one by hand. The thread got over three hundred comments, so most people did not get a prospect. This guide is the method I used, written down so you can run it yourself. It is also, in slow motion, what PumpGTM does for every customer.
Why one prospect, and why 24 hours
One prospect forces honesty. You cannot hide behind "I have a list of two thousand." You have to be able to say who the person is, why they need you, and what evidence you have.
24 hours forces you to look where the evidence already exists instead of building infrastructure. If it takes a week, you are building a scraper, not finding a customer.
One distinction I made in the thread and will repeat here: I can promise a genuine potential customer in a day. I cannot promise that a stranger will pay you within a day. Nobody controls the buyer's decision, and any tool that claims otherwise is selling you the wrong thing.
Step 1: Decide what the problem looks like when someone says it out loud
Before you search anywhere, write the sentence a person types when they have your problem and do not know your product exists. Not your positioning. Their words.
For a compliance consultancy that helps SaaS companies get SOC 2 ready, the sentence is something like "our first enterprise customer wants SOC 2 and we have no idea where to start." For a phone sun shade for creators, it is "cannot see my screen shooting outside." You are going to search for that sentence, so make it real.
Step 2: Pick the channel where the pain shows up in public
This is the step most founders skip, and it was the most common correction I gave in the thread.
- A physical product for travelers and creators: TikTok, Amazon reviews, and the niche communities where people complain. No LinkedIn, no cold outreach.
- A developer tool for people already paying for an AI assistant: the subreddits where those users hang out, and almost nowhere else. LinkedIn is a waste of time for that buyer.
- A service like compliance consulting: LinkedIn plus the subreddits where founders panic about audits. Cold outbound works here because the buyer already knows they have the problem. They just do not know you exist.
The channel is a property of the buyer, not of your preference. Pick the one where you can watch someone describe the problem today.
Step 3: Find the person, not the segment
Now search the sentence from step 1 in the channel from step 2. Read recent threads, comments, and replies until you find one person who described the problem themselves. Competitor posts are the richest vein; here is how to mine a comment section. Write down:
- Who they are and where they said it (the link).
- The exact words they used.
- Why your product fits that specific situation, in one sentence.
- One thing you still do not know about them.
That last line matters. It becomes your first question to them, which is far better than a pitch.
Step 4: Write the first line before the comparison table
One founder in the thread told me their landing page already had a comparison table, as if that settled it. A table works once someone is already comparing. The harder job is the first line, because someone who does not know they have the problem yet never scrolls down to the table.
So the first message is not "here is why we are better than X." It is a reply to the thing they said, in their words, with one useful observation and one question. If they answer, you have earned the right to say what you do. Before sending, run the line through the anti-slop checklist.
What this looks like at scale
Doing this for five companies took me most of a day. Doing it every week for your own company is a job, and it is the job PumpGTM does: find the people showing the problem in public, put the reason beside each name, draft the first message from their words, and hand you the list to approve before anything goes out. If you want to see the first batch for your own product, start at pumpgtm.com and enter your website.
Questions from the thread
What if my buyers do not post about the problem anywhere? Then either the problem is not painful enough yet, or you are looking in the wrong channel. Both are worth knowing before you spend on ads.
Is one prospect really enough to learn from? One prospect is enough to test whether your "relevant because" sentence holds up. Ten will tell you whether you have a segment.
Can I do this for a B2C product? The method works. The channel is different, and cold outreach is usually the wrong move. Show up where the complaint is and be useful there.
