Where AiSDR is strong
- Pay as you go. $1.50 per person prospected, and no card needed to sign up.
- Richer LinkedIn touches. Messages, connection requests and InMail, plus AI video and voice notes alongside email.
- Phone steps. Call steps through Aircall for teams that pick up the phone too.
- Managed options. A managed campaign for $149, or a fully managed service at $2,500 a month, if you want it run for you.
- Security. AiSDR shows a SOC 2 badge on its site.
Where Siela AI is different
- Scored before it sends. The AI SDR marks every lead hot, warm or cold with a one-line reason, and with Hot leads selected it only contacts people with a buying signal right now. Both run on their own once started; AiSDR adds a co-pilot mode for replies.
- X and social posting. Siela runs outreach on X and publishes LinkedIn and X posts. AiSDR doesn't post or send on X.
- CRM and booking built in. Siela includes a CRM and booking pages; AiSDR sends a Calendly or HubSpot link and syncs to HubSpot.
- No dialling, voice notes or video. Siela's outreach is written; its Call Agent joins video calls you've booked, but Siela doesn't do call steps, voice notes or AI video. If those are part of your outreach, AiSDR covers them.
