After the ad form: what to expect once you have handed over your number

A call or text with a ballpark number usually follows. These ads mostly launch a Meta instant form instead of a website, which means the advertiser holds your contact details before you know anything about it. Use the time before they ring.

01

A few questions, then your phone number

Expect three to five short questions (staff, years of records, where you are) and then they want a phone number. A few offer to send the quote by text. Full website calculators ask much the same, and still call the result a rough guide.

02

Find out who you just spoke to

Whoever runs the ad may not be the buyer at all. From September to mid-October 2026, dozens of new pages began advertising on Meta, mostly brokers. Meta's Ad Library lists each page's live ads and their start dates.

Look for a legal company name, a real website and named people. Our list of buyers we rank is a quick cross-check.

03

What to say when they call

  • Share your numbers: headcount, years and systems
  • Keep files, logins and samples to yourself on the first call
  • Ask for the company name, website and a written description of the offer
  • Ask which AI labs would receive the data
  • Ask how they are paid and whether you would pay anything (you should not)

You will probably hear a range lifted from the ad, often $100K to $2M+, and that is only the advertiser's word. A genuine figure arrives after the buyer reviews scrubbed samples, and everything should be agreed in writing before data moves.

FAQ

Questions, answered

I sent the form. What comes next?

Normally a phone call or text with a ballpark range, sometimes after just a couple of questions.

Why did the ad open a form inside Facebook?

Meta instant forms are fast for advertisers and keep you on the platform. They also give you nothing to read first.

Am I committed to anything?

No. A form is not a contract. Nothing should move until you sign a written agreement.
