How long should a first B2B discovery call be?
A first B2B discovery call works best at 15–20 minutes. Ten minutes is enough to confirm fit, and anything over 30 minutes tends to turn into a demo nobody asked for.
Busy decision makers accept short calls more readily than long ones, and a short slot forces both sides to get to the point. On Meetcatcher, first calls last about ten minutes by design, and that is usually enough to tell whether there is a reason to speak again. For most outreach, a 15–20 minute slot gives a little more room for questions without asking for half an hour of a stranger's day.
A 20-minute call typically splits like this: two minutes of introductions, ten minutes of questions about the prospect's situation, five minutes on how you might help and three minutes to agree what happens next. If you are sharing slides by minute eight, the call has become a demo, and the prospect booked a conversation, not a presentation.
Longer first calls make sense in a few cases: several stakeholders join, the deal is large enough to justify a workshop, or the prospect explicitly asks for a walkthrough. Then send an agenda in advance and book 30–45 minutes, rather than letting a short call overrun and leaving the prospect late for their next meeting.
A 20-minute discovery call agenda
- 1Introductions (2 min)Who you are, why you asked for the call and what you hope to leave with. One sentence each.
- 2Their situation (10 min)Ask about the goal, what they have already tried and what is getting in the way. Listen more than you talk.
- 3Your angle (5 min)Connect one thing you do to one problem you heard. Leave the full service list for later.
- 4Next step (3 min)Agree a concrete follow-up, such as a proposal, a second call with the decision maker or a short trial, and swap contact details before you hang up.
If your calls keep running out of time, the cause is usually too much pitching, not too little time. Our guide to running a great meeting breaks a ten-minute call into minutes, and online speed networking shows how short formats work when both sides come prepared.
