7 Best AiSDR Alternatives in 2026
AiSDR is an autonomous AI sales agent. It finds in-market prospects from public buying signals, researches each one against LinkedIn activity and company news, writes personalized messages, runs multi-channel sequences across email, LinkedIn, and phone, handles objections, qualifies replies, and books the meeting. Its AI Strategist will generate a full go-to-market campaign in about twenty minutes, and it syncs with HubSpot and Salesforce.
The stated philosophy is quality over volume — messages go out only when there’s a verifiable buying signal, with the research evidence in the copy, targeting one to three qualified meetings per hundred leads rather than blasting a list.
Pricing is a single tier: $900/month billed quarterly, unlimited seats, all features, 24/7 support, with credits covering messages and lead searches.
That number is the reason most comparisons start. $900/month is well under a human SDR and well over every tool in the adjacent categories, so the question becomes which part of the job you’re actually buying.
The SDR job is four jobs
Vendors bundle them differently, and the bundle is what you’re really choosing between:
- Finding the right accounts and people — data, enrichment, and intent signals.
- Deciding who’s worth contacting now — scoring and prioritization.
- Getting the message delivered — sending infrastructure, domains, warmup, deliverability.
- Everything after the reply — answering questions, handling objections, scheduling, updating the CRM, following up with the 90% who don’t answer the first time.
AiSDR sells all four as one agent. Most teams already own one or two, and the fourth — reply handling and follow-through — is where deals are usually lost.
1. Carly, for job four
Carly isn’t a prospecting engine — it doesn’t build lists, score intent, or run cold sequences. It’s on this page for the fourth job, which is where most of the pipeline these tools generate quietly dies.
Once a prospect replies, the work stops being outbound and becomes email, calendar, and CRM: answering the question, finding a time, booking it, logging it, and chasing the ones that went quiet. Carly gets its own address, handles replies from inside the thread, and runs on a schedule so nothing goes cold while a rep is heads-down.
- Your domain, your brand. Add a sending domain in the org portal, drop in a verification TXT record plus three DKIM CNAMEs and the SPF row it walks you through, forward the mailbox, verify. It sends DKIM-signed mail as
sales@yourcompany.com, and reps can CC it on a live thread to hand off the scheduling. - It sits on top of the stack you already chose. Salesforce, HubSpot, Pipedrive, Close, Attio, Salesflare, Salesmate, Apollo, and Instantly are all native, alongside around 260 integrations — and anything else with a public API connects with your own key. So it complements whichever tool above you buy rather than replacing it.
- Google Calendar and Outlook both, so booking works either way.
Driving it from your own code — provisioning agents per rep or per tenant, embedding it in your product, running high volume — is available. Book a call with the team and we’ll scope it to your setup.
Pricing: free for unlimited Zapier-style workflows, AI agents from $35/month.
Best for: teams whose prospecting works and whose follow-through doesn’t.
2. Clay
The data layer the rest of the category is increasingly built on. Waterfall enrichment across dozens of providers, AI research agents that read websites and filings, and scoring that runs on signals you define.
vs. AiSDR: Clay is far stronger at jobs one and two, and doesn’t try to be the agent that sends. Teams commonly run Clay for targeting and something else for outreach, which unbundles the $900 into parts you can evaluate separately. Credit-based, and heavy enrichment gets expensive.
Best for: targeting quality, where the list is the problem.
3. Artisan
The other well-known AI SDR, sold as a digital worker rather than a tool — sourcing, personalization, sending, and reply handling under one persona, with its own sending infrastructure and warmup.
vs. AiSDR: the closest like-for-like, and the difference is mostly philosophy. AiSDR emphasizes signal-gated, evidence-backed messages at low volume; Artisan leans toward a fuller autonomous SDR persona and higher activity. Pricing is quote-only, which makes AiSDR’s published $900 easier to plan against.
Best for: teams comparing full-stack AI SDRs head to head.
4. Apollo
Contact database, sequencing, dialer, and basic AI in one place, at a price point far below the agent category.
vs. AiSDR: you drive it. There’s no agent deciding who to contact or writing genuinely researched messages, and reply handling is yours. But it covers jobs one and three competently for a fraction of the cost, and for many teams the honest answer is that they never used their existing sequencer properly. Apollo is also a native Carly integration, so replies can be handled automatically on top.
Best for: teams who want a database and a sequencer without agent pricing.
5. Instantly
Sending infrastructure specialists — mailbox management at scale, warmup, rotation, deliverability monitoring, and inbox placement testing.
vs. AiSDR: solves job three and nothing else. That’s the right buy when messages are good and nothing lands, which is a deliverability problem no amount of AI personalization fixes. Also a native Carly integration.
Best for: volume outbound where inbox placement is the bottleneck.
6. Outreach or Salesloft
The enterprise sales engagement platforms — sequences, dialer, conversation intelligence, forecasting, and the reporting a sales leader is measured on.
vs. AiSDR: built for a team of humans with AI assistance, not an autonomous agent. Heavier to deploy and priced per seat, so they only make sense past a certain headcount, but they’re what a real sales org runs on. Outreach alternatives and Salesloft alternatives compare both.
Best for: established sales teams that need process and reporting.
7. Lindy
Role-based AI employees, including SDR-shaped ones, configured with your own triggers and tools rather than shipped as a finished sales product.
vs. AiSDR: more assembly, more control, no opinion about how outbound should work. You bring the data source and the sending setup and define the behavior. Credit-metered per task. Lindy alternatives covers the field.
Best for: teams who want to design the motion rather than buy one.
Choosing between them
Your list is the problem. Clay. Better targeting beats better copy every time.
Your deliverability is the problem. Instantly. Nothing else matters if mail doesn’t land.
Your replies are the problem. Carly, for a fraction of an SDR platform — answering, qualifying, booking, logging, and chasing the quiet ones.
You want the whole motion outsourced to an agent. AiSDR or Artisan. AiSDR’s signal-gated approach and published $900/month make it the easier one to evaluate, and unlimited seats matter if the team is larger than a couple of reps.
You have a real sales team. Outreach or Salesloft, with the agent layer added where it helps.
Before spending $900/month on outbound, count how many current replies never got a second follow-up. That number decides which of these you actually need. AI agents for SDRs goes deeper on the role, and the best AI agents for sales ranks the broader field.
FAQ
What is AiSDR?
AiSDR is an autonomous AI sales agent that finds in-market prospects from public buying signals, researches each lead against LinkedIn activity and company news, writes personalized messages, runs multi-channel sequences across email, LinkedIn, and phone, handles objections, qualifies replies, and books meetings. It integrates with HubSpot and Salesforce, and its AI Strategist builds a full campaign in about twenty minutes.
How much does AiSDR cost?
$900/month, billed quarterly with no long-term lock-in. That covers unlimited seats, all features, and 24/7 support, with credits for messages and lead searches. It’s a single tier rather than a ladder, so the comparison is straightforward against per-seat platforms.
What is the best AiSDR alternative?
It depends which part of the job is failing. Carly handles everything after the reply — qualification, scheduling, CRM updates, and follow-up — at a fraction of $900/month, which is where most generated pipeline actually dies. Beyond that: Clay for targeting and enrichment, Instantly for deliverability, Artisan for a like-for-like autonomous SDR, and Apollo for a cheaper database and sequencer.
Can an AI SDR replace a human SDR?
It replaces the mechanical share of the role: research, first-touch personalization, sequencing, and routine reply handling. It doesn’t replace judgment about which accounts matter, relationship building with a champion, or the conversation where a deal is actually won. Most teams that get results run one AI-driven motion alongside a smaller human team working the accounts that justify a person.
Is AI outbound email still effective in 2026?
Only when it’s genuinely targeted. Inboxes are saturated and filters are aggressive, so volume-first outbound performs worse every year while signal-gated, well-researched outreach still works — which is why AiSDR targets one to three qualified meetings per hundred leads instead of maximizing sends. Deliverability fundamentals matter more than the copy: authenticated domains, warmed mailboxes, and low complaint rates.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
