AiSDR

AiSDR is now self-serve pay-as-you-go at $1.50 per person prospected, with no monthly fee. Sign-up needs no card, and you pay only when you launch a campaign. Monthly, quarterly and annual subscriptions are sold through sales, and a fully managed service is $2,500/mo. The earlier Solo ($250/month), Explore ($900/month billed quarterly) and Scale plans are no longer listed on the AiSDR pricing page. There is no free plan.

A junior SDR in the US costs $4,000-6,000/month in salary alone, plus benefits, tools, training, and ramp time. AiSDR, billed at $1.50 per person prospected with no monthly fee (or $2,500/month as a fully managed service), replaces the prospecting, initial outreach, and follow-up portions of an SDR role. The platform claims a 40% increase in outreach conversion rates for its clients. For teams that need volume-driven outbound without hiring headcount, the math works. However, AiSDR cannot handle complex discovery calls, negotiate, or build relationships the way a human SDR can. It is best positioned as a supplement to your sales team or as a replacement for the most repetitive parts of outbound.

AiSDR does not offer a free plan. Sign-up needs no card, though, and there is no monthly fee: on the self-serve pay-as-you-go plan you pay $1.50 per person prospected, and only when you launch a campaign. If you need a free option for AI-assisted sales outreach, consider Apollo.io free tier or HubSpot free CRM as starting points.

Reply.io starts at $59/month for email-only outreach and $89/user/month for multichannel, while AiSDR now charges $1.50 per person prospected with no monthly fee, so which is cheaper depends on how many people you prospect. Reply.io offers its Jason AI SDR agent, multichannel sequences, and a broader feature set including calls, SMS, and WhatsApp. AiSDR focuses purely on AI-driven prospecting and outreach with a larger built-in database (700M+ leads) and signal-based targeting. Choose AiSDR if you want a fully autonomous AI agent that handles end-to-end outreach with minimal human input. Choose Reply.io if you want flat monthly pricing with human-in-the-loop multichannel capabilities.

AiSDR integrates natively with HubSpot for CRM sync, allowing you to import lists and sync outreach activity. Emails are sent through Gmail and Outlook directly, not through third-party servers, which helps with deliverability. AiSDR also supports LinkedIn outreach. The integration ecosystem is narrower than competitors like Reply.io or Apollo.io, which support Salesforce, Pipedrive, and dozens of other tools via native integrations and Zapier.

AiSDR uses a built-in database of 700M+ contacts and enriches them with real-time intent signals including funding rounds, hiring activity, tech stack changes, and media mentions. The platform triple-checks email addresses to keep bounce rates below 5%. You can also import your own lists from HubSpot. This signal-based approach means AiSDR targets prospects who are actively in-market, rather than blasting cold lists.

Yes. AiSDR supports LinkedIn personalization as part of its outreach capabilities. The platform can send personalized LinkedIn messages alongside email sequences. Unlike Reply.io where LinkedIn automation is a paid add-on, AiSDR includes LinkedIn outreach. However, AiSDR does not support calls, SMS, or WhatsApp channels.
