How AI SDR pricing works

Three of the six AI sales agents here publish prices. AiSDR sells monthly plans sized by how many contacts it researches. Solo is $250/mo for 200 contacts ($200/mo billed yearly) and runs month to month. Explore ($900/mo) and Scale ($2,500/mo) cover more contacts but need a quarterly commitment.

Regie.ai charges per user plus monthly credits. It has a free plan with 250 one-time credits per person, Pro at $49/mo ($41/mo billed yearly) and Team at $150/seat/mo with a 2-seat minimum. Credits pay for research, drafting, enrichment and dialing. Alice by 11x sits at the other end. It is an annual contract priced per prospect. Its Growth plan is $3,750/mo billed yearly ($45,000 a year). Pro and Enterprise are custom priced.

Ava by Artisan, Piper by Qualified and Conversica are quote-only. Artisan sizes its quote to leads, mailboxes and dialer seats. Qualified sizes Piper by web sessions and email contacts. Conversica does not publish prices at all. Regie.ai is the only agent here with a free plan and none lists a timed free trial, though AiSDR lets you sign up without a card and set things up before you pay.

What we check

Books meetings on its own

We check whether the agent books meetings itself or leaves that step to your reps.

Channels

We list which channels each agent uses, from email and LinkedIn to phone, SMS, WhatsApp and website chat.

Handoff to your reps

We note when the agent passes a ready prospect or a booked meeting to a human and whether it ever makes calls.

Contract and pricing model

We record whether you pay monthly, quarterly or yearly and whether prices are public or quote-only.

CRM and tool sync

We check which CRMs and tools each agent connects to, such as Salesforce, HubSpot and Slack.

Every fact comes from the vendor’s official site. How we review

How to choose

  • If you are a founder or small team testing an AI SDR: AiSDR. Solo is $250/mo month to month and every plan includes email, LinkedIn and phone outreach through Aircall.
  • If you are a single rep who wants help rather than a full agent: Regie.ai. It has a free plan and a $49/mo Pro plan with a power dialer, though you still talk on the calls and book the meetings.
  • If you want the leads supplied along with the outreach: Ava by Artisan. Ava comes with 250M+ verified B2B contacts, writes the emails, handles replies and books meetings on your calendar.
  • If most of your buyers arrive on your website: Piper by Qualified. Piper talks with visitors by chat, voice or video and books meetings while they are still on the page.

FAQ: AI sales agents

What is an AI SDR?

An AI SDR is an agent that does the work of a sales development rep. It researches prospects, sends outreach, handles replies and books meetings. Alice by 11x, AiSDR and Ava by Artisan all work this way on outbound. Piper by Qualified and Conversica follow up with leads already in your funnel, such as website visitors and large lead lists.

How much does an AI SDR cost?

Published prices on this page run from $250/mo for AiSDR Solo to $3,750/mo billed yearly for the Alice by 11x Growth plan. Regie.ai costs less with a free plan and Pro at $49/mo, but it helps reps rather than booking meetings on its own. Ava by Artisan, Piper by Qualified and Conversica use custom pricing, so you need a demo or a sales call to get a number.

AI SDR vs a human SDR: what does each do best?

On this page the AI handles research, outreach, follow-up and booking. People take over once a prospect is ready to talk. AiSDR escalates ready prospects to your reps, Ava by Artisan hands booked meetings to reps and does not place calls herself and Piper hands off to a live rep on its Enterprise and Ultimate plans. With Regie.ai the rep still talks on every call and books the meeting.

What's the best AI sales agent for a small team?

AiSDR is built for founders and small sales teams. Solo is $250/mo for 200 contacts with no long contract and Explore at $900/mo adds unlimited users with a quarterly commitment. For a single rep on a tight budget, Regie.ai has a free plan and a $49/mo Pro plan. Alice by 11x starts at $3,750/mo billed yearly, so it suits funded teams with a set outbound budget.
