Apollo.io vs AiSDR
Quick answer
Apollo.io is the better fit for founders and SDRs doing their own outbound prospecting. AiSDR is the better fit for B2B founders who need outbound pipeline but have no SDR yet. On our scores Apollo.io comes out ahead overall (4.4 out of 5).
Apollo.io
Apollo.io combines a database of about 240 million contacts and 30 million companies with sequences, a dialer, enrichment and AI agents. For startups and small sales teams it can replace a data tool and an outreach tool at once, and the free plan has no time limit. Watch the credit system: credits are pooled, reset every billing cycle and never roll over.
- ✓Large database: about 240M contacts and 30M companies
- ✓Free plan stays free with no time limit
- ✓Sequences, parallel dialer and deliverability tools built in
- –Credits reset each billing cycle and do not roll over, even purchased add-ons
- –Free plan connects Gmail accounts only for sending
AiSDR
AiSDR bundles lead data, research, AI-written multichannel sequences, mailbox deliverability and reply handling into one AI agent, so a small team can run outbound without a full SDR stack. Pay-as-you-go at US$1.50 per prospect makes testing cheap, but team plan prices are unpublished, contracts are quarterly, and the results figures come from AiSDR itself.
- ✓One tool covers lead data (2B+ profiles), research, writing, sending and replies
- ✓Pay-as-you-go at US$1.50 per person prospected, charged daily, stop anytime
- ✓No credit card or sales call needed to sign up and build a campaign
- –Team plan prices are not published and need a sales conversation
- –Team plans are billed monthly but sit on quarterly contracts
