What is an AI SDR?
An AI SDR is software that does the job of a sales development representative: it finds prospects, researches them, writes personalized outreach, follows up, answers early questions, and books qualified meetings on a real calendar. Instead of one human working a list, an AI SDR runs the same playbook continuously and hands finished work to a person for approval. The term covers everything from email-only tools to voice agents that call new leads back. Costs range from free tiers where you bring your own AI keys to four-figure monthly contracts.
How an AI SDR works
You give the AI SDR three things: a description of your ideal client, a clear picture of your offer, and access to your calendar. From there it runs a loop. It sources prospects or picks up inbound leads, gathers context on each one, drafts the outreach (an email, a call, or both), handles the early back and forth, and proposes meeting times that actually exist on your calendar.
Under the hood it is a language model wired to real tools: a lead database or web search for sourcing, an email account for sending, a phone system for calling, and a scheduler for booking. The model decides what to say. The tools let it act. Good systems log every action on the contact record, so you can audit any conversation later.
The key design question is autonomy. Some AI SDRs send everything automatically. The safer pattern is human-in-the-loop: the AI prepares the work, and you approve, edit, or dismiss each piece before it goes out. You trade a little speed for a lot of control over your reputation.
AI SDR examples in practice
Here is what the job looks like day to day for a small business:
- A lead fills out your website form at 2:14 pm. The AI SDR calls them back in about 90 seconds, answers basic questions, and books a slot that is genuinely open on your calendar.
- A prospect thread has been quiet for 3 days. The AI drafts a short bump that references the last message, and queues it for your approval before anything sends.
- You upload a list of 60 conference contacts. The AI researches each one, flags the 20 that match your ideal client profile, and lines up a personalized first touch for each.
- A repeat caller rings your inbound line. The AI recognizes them, pulls up their history, and either answers or transfers the call to your cell if it is hot.
Why AI SDRs matter
Leads cool fast. A person who just asked about your service is at peak interest for minutes, not days. Most solo founders and small teams cannot answer in minutes because they are delivering client work, on calls, or asleep. The deals that die in that gap were winnable.
Follow-up has the same problem. Replies usually come after several touches, but each touch is a small chore that loses to whatever is on fire that day. An AI SDR never gets busy and never forgets the fourth follow-up. The humans keep the part humans are good at: judgment, relationships, and closing.
How Orbit handles the AI SDR role
Orbit is a CRM with a built-in AI team of 16 named agents, and several of them cover the SDR job together. Remy, the voice SDR, calls new form leads back in about 90 seconds, answers your inbound line, recognizes repeat callers, books meetings from your real calendar availability with invites sent, and transfers hot calls to your cell. Niko hunts the open web for leads that match your ideal client profile and vets each one against your offer. Ivy enriches new leads with email, socials, and background. Tess scans your inbox each morning and drafts bumps for threads that have been quiet 3 or more days.
Every output lands as a card you approve, edit, or dismiss. Nothing auto-sends. Voice agents are off by default, only call inside hours you set, respect a daily cap (default 25), and run on your own Vapi account and number. You bring your own AI keys, so providers bill you directly at cost; typical solo usage runs cents to a few dollars a month.
An AI SDR removes the waiting, the chasing, and the blank page. The judgment stays yours.

Frequently asked questions
Is an AI SDR the same as an AI agent?+
An AI SDR is one kind of AI agent. AI agent is the broad category: software that works toward a goal using tools. An AI SDR is an agent aimed specifically at sales development work, meaning prospecting, outreach, follow-up, and booking meetings.
How much does an AI SDR cost?+
Prices vary widely. Dedicated AI SDR platforms often charge hundreds to thousands of dollars per month. Some CRMs, including Orbit, include AI SDR agents free and let you bring your own AI and voice keys, so you pay providers directly at cost, which for light solo use is typically cents to a few dollars a month.
Will leads know they are talking to an AI?+
They might ask, and a well-configured AI SDR answers honestly. Reputable setups also disclose recorded lines on calls. Trying to pass an AI off as human is a fast way to lose trust, so the standard practice is honest disclosure whenever the question comes up.
Can an AI SDR really book meetings?+
Yes, when it is connected to a real calendar. A good AI SDR reads actual availability, offers only slots that are open, books the meeting, and sends calendar invites to both sides. Without calendar access it can only suggest times, which reintroduces the back and forth.
Does an AI SDR replace a human salesperson?+
No. It replaces the repetitive early-stage work: the instant callback, the fourth follow-up, the list research. Humans still run discovery calls, build relationships, negotiate, and close. For solo founders, the AI SDR mostly replaces work that was simply not getting done.
