How to get your first 100 customers for an AI SDR agency delivering booked meetings
To win your first 100 customers for an AI SDR agency that delivers booked meetings rather than software seats, go where founders and sales leaders already complain about empty pipeline instead of buying ads. The highest-fit communities are r/sales and RevGenius (where revenue leaders debate outbound that actually works), founder spaces like r/startups, Indie Hackers and SaaS Slack/Discord groups, and sales-ops communities like Sales Hacker and Pavilion. Sell the outcome — 'qualified meetings on your calendar, pay per meeting, no extra headcount' — and a zero-audience founder can fill a pipeline for free.

FAQ
Where do B2B founders and sales leaders who need pipeline gather online?
They cluster in r/sales, r/startups and r/SaaS, in revenue communities like RevGenius, Pavilion and Sales Hacker, on Indie Hackers and Hacker News, and in SaaS/GTM Slack and Discord groups. These are where 'what's working for outbound?' and 'how do I get more meetings?' questions appear constantly.
What's the fastest way to get the first 100 customers for an AI SDR agency?
Sell the outcome, not software: qualified meetings on the calendar, paid per meeting, no extra headcount. Be relentlessly helpful in the communities above, pick one wedge like seed-stage SaaS founders with no SDRs, run a small pay-per-meeting pilot for a few clients, and turn booked-meeting numbers into testimonials that drive referrals.
Do I need an ad budget?
No. These are organic communities a founder with zero audience can engage for free. Helpful outbound insights plus a low-risk pay-per-meeting pilot offer are enough to land your first clients.
