AiSDR

What it is

AiSDR is an AI sales rep that runs outbound and inbound prospecting with light human oversight. It finds contacts against your ICP, researches each one from recent posts and company news, writes the copy, and runs multi-step sequences across email and LinkedIn — then handles replies, answers product questions, qualifies, and books the meeting. Calls go out as steps through an Aircall dialer rather than through a native phone agent. The front end is now Ami AI, the vendor’s AI strategist: you drop in a URL and one real email, Ami analyzes the business and drafts the ICP, the GTM plan, and the sequences, and a human edits rather than builds. The role AiSDR replaces is a junior SDR plus a data subscription plus a sequencer, and the head-to-heads are 11x’s Alice and Artisan’s Ava. What separates it from both is mundane and decisive: it publishes its price, and since mid-2026 that price starts at $250/mo.

Why it shows up in RevOps stacks

• $250/mo, self-serve, month-to-month. 11x and Artisan are demo-gated and quoted in annual, prepaid contracts. AiSDR’s Solo tier lists $250/mo, signs up without a sales call, and cancels anytime. That is a 72% cut from the $900 floor the vendor carried into early 2026, and it is the lowest entry barrier in agentic outbound.
• The HubSpot integration is the deepest in the category, and it starts on the cheapest plan. Native two-way sync — lists, contact properties, activity logging, AI account scoring, saved call scripts, intent tracking — ships on Solo. Salesforce does not: two-way Salesforce sync is gated to the $2,500/mo tier.
• One bill covers data, sending, and warmup. A 300M+ contact database, mailbox provisioning, ongoing domain warmup, triple bounce checks, and automated inbox rotation sit inside the plan, so you are not stacking a data vendor and a deliverability tool on top of the agent. AiSDR prices this against the stack it displaces — lead database, email sequencer, LinkedIn sequencer, visitor identifier — and puts the saving near half.

Pricing reality

Three published tiers, all billed monthly, all metered in AI-researched contacts — the net-new leads AiSDR finds, qualifies, and enriches each month — rather than seats or messages. Solo is $250/mo for 200 contacts, 1 user, 1 sending domain, 3 mailboxes, and 1 LinkedIn account, month-to-month with self-serve signup. Explore is $900/mo for 800 contacts, unlimited users, 2 domains, 6 mailboxes, and 5 LinkedIn accounts. Scale is $2,500/mo for 2,500 contacts, 6 domains, 18 mailboxes, and 20 LinkedIn accounts, and it is the only tier carrying native two-way Salesforce sync, AI video, AI voice notes in LinkedIn messages, and website-visitor tracking. Explore and Scale run on a quarterly contract; Solo does not. An annual commit takes 20% off, landing at $2,400, $8,640, and $24,000 per year. There is no free trial and no Enterprise tier on the pricing page. Managed service is an add-on rather than a plan: +$149 per campaign on Explore, +$2,500/mo fully managed on Scale, which doubles the bill. Unused messages roll into the next quarter while the subscription is active, and passing the contact cap means paying overage or pausing campaigns. The vendor’s own yield benchmark is 1-3 meetings per 100 contacts — roughly 2-6 meetings/mo on Solo and 25-75 on Scale. Treat that as the vendor’s number, not yours.

Best for

Founders and solo sellers under roughly $3M ARR running HubSpot who want a live outbound motion this month at the price of a mid-tier data subscription. Solo is the cheapest honest way to find out whether an AI SDR works in your niche, and the downside is one month. Above that, seed-to-Series-B teams in the $1-10M ARR band with no SDR bench belong on Explore, where the mailbox count supports real volume.

Don’t buy AiSDR if you need fine-grained control over targeting and sequence logic — the playbooks are configurable, not programmable, and power users hit that ceiling fast. Don’t buy Solo if Salesforce is your system of record: two-way sync is a $2,500/mo feature, and an agent that can’t write back to your CRM turns into a data-entry job. Skip it for complex, high-ACV outbound where a trained rep’s judgment still beats the agent. And weigh the vendor’s scale before betting a core motion on it: AiSDR has raised about $3M and is far smaller than its two rivals.

Versus the alternatives

11x and Artisan are the two established poles, both quote-gated and both annual. Vendr data puts 11x’s median contract near $40,000/year and Artisan’s at $26,000-30,000/year — 11 to 17 times AiSDR’s $2,400 Solo annual. Pick 11x when you want a built-in phone agent and a tighter security story, pick Artisan when its bundled contact database matters, and pick AiSDR when a visible price and a one-month exit matter more than either. The fast-growing alternative architecture is signal-driven outbound like Unify, which fires plays off warm intent instead of running autonomous volume — choose it when you’d rather act on signals than rent a rep. The cheaper status quo is Apollo plus a human SDR at $49-99/seat/mo, where the rep brings judgment the agent doesn’t. And GTM engineers who want control can assemble Clay plus Claude for steerable signal-to-copy at lower spend, trading setup time for it.

Watch-outs

• Mailboxes cap your real volume, not the contact number. Solo’s 200 contacts spread across 3 warmed mailboxes is a sane ratio; what the tier jump actually sells is sending infrastructure — 6 mailboxes on Explore, 18 on Scale. Guard: size the tier off domains and mailboxes against your target send volume, then check the contact allowance covers it, not the other way round.
• First-month results are usually thin because of warmup. New sending domains need 30+ days of warmup before full volume, which is the vendor’s own stated reason for the quarterly contract on Explore and Scale. Reviewers report minimal replies in the first campaigns, with Outlook safe-sender and deliverability snags early on. Guard: start warmup on a separate sending domain weeks before you judge the tool, and set the success gate at the end of the first quarter, not the first month.
• You can configure the playbooks but not rebuild them. Reviewers consistently flag the absence of custom signal logic and branching. Guard: run one paid cycle against a narrow ICP and count meetings that pass your own qualification bar before moving up a tier.
• It’s a small vendor backed by ~$3M. AiSDR raised a ~$2.96M seed in 2023 from Y Combinator, Flyer One Ventures, Rebel Fund and others, and is a fraction of the size of 11x or Artisan. Guard: confirm the integrations you depend on are live on the tier you are buying — the pricing page gates several of them — and keep your data exportable so a vendor stumble doesn’t strand your pipeline.
• Calls depend on Aircall, not a native phone agent. Unlike 11x’s Julian, AiSDR queues call steps and personalized scripts through an Aircall dialer instead of running an autonomous voice rep. Guard: if phone is a real channel for you, price the Aircall seat in and don’t expect the agent to hold a live conversation.
