An AI SDR (sales development rep) is software that does the early steps of outbound sales, meaning contacting possible buyers who have not asked to hear from you. It finds people to contact, writes the first message and sends it. AiSDR is the company and Ami is its agent. Ami also handles replies and keeps HubSpot in sync.

Key features of AiSDR

• Campaign building: Ami builds the campaign, writes each message for one person after research, runs it and adjusts it as replies come in.
• Finding people: AiSDR looks for contact details across a waterfall of 20 data providers. A waterfall tries one provider after another until it finds a result.
• Reply handling: replies are handled in 5 to 10 minutes, or in co-pilot mode. Ask what co-pilot mode lets a person approve. Your first campaign can stay behind an approval step, and you can keep a person in the loop wherever you want one. A unified inbox keeps them in one place.
• Multi-channel sequences: you can set up steps across email and LinkedIn, one after another, and add AI call steps with the Aircall dialer.
• Meetings: AiSDR books meetings and connects to Calendly and HubSpot calendars.
• Email checks: three bounce checks, including for catch-all addresses. A bounce is an email that cannot be delivered. A catch-all address accepts mail for any name, so a basic check cannot tell whether the person exists.
• Sending set-up: sending runs on lookalike domains (extra web addresses close to your own), with continuous warm-up and monitoring. Warm-up means raising the daily volume of a new mailbox slowly, so inbox providers learn to trust it.
• CRM sync: HubSpot is kept in sync both ways. Salesforce comes with team plans. A CRM is the system where you track your deals.
• Done-for-you options: AiSDR sells a warmed-up mailbox, a managed service for one campaign, and a fully managed service.

Who AiSDR fits

If you are a solo founder who wants to test outbound without a contract, pay as you go starts with no sales call and you can stop anytime. If you run a small team that uses HubSpot, AiSDR keeps HubSpot in sync. If you contact 1,000 or more people a month, team plans are quoted, and they cost up to 40% less per contact. They add Salesforce and a dedicated GTM engineer (GTM means go-to-market, the work of finding and winning customers). If you do not want to run campaigns yourself, AiSDR sells managed service. If you need one fixed monthly bill, per-person pricing moves with the size of your list, so compare the flat-fee tools below.

AiSDR pricing

Frequently Asked Questions

Bottom line

AiSDR fits a founder or a small sales team that wants to pay per person, start without a sales call and have replies handled. Before you buy, check three things. Ask what counts as one person prospected. Ask which plan includes Salesforce and what a person can approve once a campaign is running. And ask who owns the sending domains. Pay as you go lets you start small and stop anytime.
