Why teams switch to ClinchRev
The most common reasons B2B sales teams make the move.
Tool sprawl
Running Apollo + Aircall + HubSpot + Stripe means 4 subscriptions, 4 logins, and broken syncs between them. ClinchRev replaces all four in one workspace.
No AI calling in their stack
Apollo and Outreach are built around email. Teams that want to add AI voice calling have to bolt on a separate tool — and it never quite connects. ClinchRev has calling built in from day one.
Enterprise pricing on a startup budget
Outreach and Salesloft require annual contracts and cost $100+/seat. ClinchRev starts at $149/month per workspace — not per seat — and is month-to-month.
Frequently asked questions
What is the best Apollo.io alternative with AI calling?+
ClinchRev is the most direct Apollo.io alternative with built-in AI cold calling. Apollo covers prospecting and email — ClinchRev adds AI voice dialing, a lead CRM, and Stripe billing in one platform at a comparable price point.
What should Air.ai customers switch to?+
After the FTC's $19M judgment against Air.ai, most teams are migrating to ClinchRev or Bland.ai. ClinchRev is the better fit if you also need email sequences, a CRM, or billing — not just AI voice.
Is ClinchRev cheaper than Outreach?+
Yes. Outreach starts at $100+/seat/month and requires an annual contract plus a sales call to get started. ClinchRev starts free and paid plans begin at $149/month per workspace — not per seat.
How does ClinchRev compare to Synthflow?+
Synthflow is a voice-only builder — you configure AI voice flows but there's no email outreach, CRM, or billing. ClinchRev includes all of those alongside AI calling, so you don't need to stitch together multiple tools.
Does ClinchRev replace multiple tools?+
Yes. A typical outbound sales stack — Apollo + Aircall + HubSpot + Stripe — costs $600+/month and takes weeks to integrate. ClinchRev combines AI calling, email sequences, CRM, and billing starting at $149/month.
