Customer-discovery briefs for founders

A verdict you
can check.

We read what your customers actually wrote — on Reddit, Hacker News, and IndieHackers — and hand back a build-or-kill verdict with the argument behind it.

Their pain in their own words, named people you can email, and what they pay today. Every claim carries its source, and the brief prints what it could not find.

The problem

You’re about to spend six months on a guess.

Every founder validates. Almost none of the evidence can say no.

The survey

“Would you use a tool like this?”

94%

said yes · n=31 · none paid

Flatters you

The chatbot

“Your target customers are clearly frustrated with existing tools and would welcome this solution.”

Invented

The interview

“Honestly? I’d totally pay for that.”

— your most supportive friend

Too kind

The people who would actually pay already told the truth — in public, in writing.

That is what a brief reads.

The brief

What you walk away with

Every brief answers the questions you can’t Google— about your customer, your market, and whether to build at all.

  • 01

    Whether to build.

    brief.pdf

    A verdict on the cover — go, wait, park, or kill — the argument that produced it, and the one test that would settle it.

  • 02

    What your customer actually says.

    quotes.csv

    The pains that recur, in verbatim quotes, each with the handle who wrote it, the date, and a link to the post.

  • 03

    Who to email on Monday.

    leads.csv

    Named people who match the buyer, with a contact path, the post that proves the fit, and a first message drafted for each.

  • 04

    What the alternative costs.

    one-pager.pdf

    What your buyer pays today — competitors read off their own pricing pages, and the human alternative priced from public wage data.

  • 05

    Where the evidence stops.

    excluded.csv

    The searches that came back empty, the venues that refused us, and every candidate we rejected with the reason.

Five files every time: the decision brief, a one-page summary, and three spreadsheets — the leads, the quotes, and the rejects. Download them, or read them in the browser.

Process

How it works

01

Hand over the raw material

Paste the pitch, the rant, the landing-page copy — or drop the deck as a PDF. It comes back as a structured draft in three short steps; you correct what's wrong and check out.

02

The agent reads

It works through your customers' communities — Reddit, Hacker News, IndieHackers — collecting verbatim quotes, named people, and prices, and recording every search that came back empty.

03

Read the verdict

Within twenty-four hours: the decision brief and a one-page summary, with the leads, the quotes and the rejects as spreadsheets you can open. Every claim carries its source.

Method

Every brief prints what it could not find.

A tool that only reports its hits reads exactly like a tool that invents them. So each brief carries its own negative space.

The searches that came back empty, the venues that shut us out, and every candidate we threw away with the reason why. You get the edge of the evidence, not just the comfortable middle of it.

Where we looked

Every venue searched, including the ones that returned nothing.

What we threw out

Every rejected candidate ships with the reason it was rejected.

  • LeadYC W23 with named enterprise customers and a mature product — past PMF; adjacent, not the pre-PMF buyer
  • Leadsatirical “I sold my SaaS for $1.5B” joke AMAs — not real founders, no ICP, no contact
  • Quoteempty quote text in the extract — attribution without words is not a verbatim quote
  • Sourcesells discovery-as-a-service to founders — a competitor to the job, not a customer for it

A brief that names ten reachable people has usually read past a hundred. The hundred are not the waste product of the work — they are how you know the ten were chosen rather than scraped.

Excerpted from a brief we ran on briff itself, with the candidates’ names withheld here. What comes back differs on every run — which is precisely why it gets printed rather than promised.

Proof

Don’t take our word for it. Read one.

A complete brief, exactly as delivered — the verdict, the argument, the quotes, the leads, the rejects.

This one we ran on briff itself, with the candidates’ names blanked. Yours is built the same way, about your customer, from their real conversations.

hello@briff.ai

A chatbot invents customers, quotes, and sources, and never tells you what it failed to find. Every quote in a briff is verbatim with a clickable URL, and every brief prints the searches that came back empty. The comparison table above has the full ledger.

They cite documents about your category — filings, articles, other people's research. A briff cites your customers: verbatim quotes with handles and links, plus named people you can email with a drafted opener. One says the category is real; the other hands you the first ten conversations.

Then we say so, and we show the evidence that got us there — including whichever of your assumptions it contradicts. A brief that talks you out of six months of building is the most valuable one we sell, and it costs exactly the same as one that doesn't.

The verdict also names the inputs that drove it — your runway, your stage, your price. Where an input is doing the work, the brief says so, so you can change it and run again rather than argue with a conclusion.

leads.csv is the working list: named people who match your buyer, where to reach them, the post that proves the fit, and a first message drafted for each. quotes.csv is every verbatim quote with its handle, date, and link, so you can lift your customers' own language straight into your copy.

excluded.csv is everyone we considered and dropped, with the reason for each. That one exists so you can audit our judgment instead of taking it on faith.

Promised: under twenty-four hours. Typical: under one hour. The 24-hour SLA exists because some briefs need more careful synthesis or hit longer scrape windows. Most don't.

Yes. 100% refund within 7 days on one-time purchases, as long as you haven't redeemed all your briefs. Subscriptions: cancel any time, no refund on the current month, but you keep the credits already issued for that cycle.

We also won't deliver a brief that fails our pre-delivery checks — a citation that doesn't resolve to a real source, or a figure in the text that disagrees with its own table, blocks the brief. Those are regenerated at our cost; you never see broken output.

No. Briff only reads public-internet content — Reddit, Hacker News, IndieHackers, public forums, public newsletters. We don't have access to paywalled Substacks, private Slack groups, or invite-only Discord servers. If your persona only talks in private spaces, briff isn't the right tool.

Only you. The agent reads your inputs, generates the brief, and delivers it to you alone — no one at briff ever sees what you submit or what comes back.

Nothing you submit is ever published or shared. Your idea, your persona, and your brief stay private, encrypted at rest, and yours to delete at any time.

Your account stays open and your past briefs stay accessible. To generate a new one, buy more credits at any tier — or start a $500 / month subscription.
