AI SDR Tools Compared: AiSDR vs Artisan vs 11x vs Regie.ai

An AI SDR is software that performs the research, messaging, and follow-up tasks that a human sales development representative would normally handle. The current generation of tools typically combines a proprietary data layer for prospect research, a large language model for personalisation, a sending infrastructure for email and sometimes LinkedIn, and a reply-handling layer that either routes responses to a human or attempts to continue the conversation autonomously. The promise is straightforward: ten thousand personalised touches a week at a fraction of the cost of a fully loaded SDR salary.

The reality is more nuanced. AI agents now handle around 80% of the research and sequencing work in elite outbound teams, according to Instantly's 2026 cold email benchmark report, but human judgement still matters for strategy, offer design, and objection handling. The best AI SDR deployments in 2026 are not replacements so much as force multipliers. They take the repetitive, rules-based parts of prospecting off a human's plate and let that human focus on the first meeting, the follow-up call, and the nuanced close.

Leadriver has tested every platform in this comparison on behalf of B2B clients scaling outbound into European markets. We run a multi-channel approach combining human-written messaging, warmed-up domains, and tight ICP targeting, so our lens on these tools is practical: did the platform move the numbers that actually matter, or did it just generate more activity?

Pricing is where the AI SDR market fractures sharply. AiSDR is the only tool in this comparison that publishes its rates openly. The base package starts at $900 per month with quarterly billing, and annual commitments bring a 20% discount. For mid-market B2B teams, this puts AiSDR at roughly $10,800 per year before discount, which sits below the entry point for most enterprise-tier AI SDR platforms. The transparency itself matters. Teams trying to build a business case for AI-assisted outbound need numbers they can put in a spreadsheet without sitting through a demo.

Artisan positions itself as an enterprise platform and reflects that in pricing. According to published comparisons, Artisan AI costs between $2,400 and $7,200 per month depending on the number of multichannel agents deployed and contract length, with most plans requiring an annual commitment. Public pricing is not listed on the Artisan site, and teams must book a sales call to get a quote tailored to their use case. The tool bundles its own data layer, so that pricing includes research and contact enrichment alongside the AI SDR functionality.

11x sits at the top end of the market. Pricing analysis published by Prospeo puts 11x at $5,000 to $10,000 per month for high-ACV sales teams, with annual commitments typical and six-figure total contract values common for large deployments. The tool is sold primarily to companies with enterprise sales motions where the cost of a missed meeting with a qualified buyer justifies heavy investment in research quality. Regie.ai takes a different approach, pricing between $3,450 and $13,000 per month for teams of ten or more reps, and positioning itself as a layer that enhances existing sales engagement platforms rather than replacing them.

The total-cost picture gets complicated fast. Enterprise AI SDRs typically require separate investment in data providers, inbox infrastructure, and implementation support. A realistic year-one budget for an 11x or Artisan deployment lands in the $60,000 to $100,000 range once you account for the platform licence, supporting tooling, and the human oversight time needed to keep the campaigns on-brand. AiSDR and Regie.ai often come in meaningfully lower on total cost for the same work, particularly for teams that already have strong data or sequencing tools in place.

Reply rates are the right benchmark for any AI SDR because every other metric downstream depends on them. The average cold email reply rate across B2B outbound in 2026 sits at 3.43%, according to published benchmark data from Instantly. Elite campaigns exceed 10%, and the top quartile consistently lands at 5.5% or higher. These are the numbers against which any AI SDR deployment should be measured, and they are the numbers most AI SDR vendors will not quote openly in case studies.

Signal-based cold outreach, which references a specific buying trigger such as a funding round, a technology adoption, or a leadership change, produces reply rates between 5% and 18% in 2026. Generic cold outreach, even when it is technically well-written, produces reply rates between 1% and 3%. This gap matters enormously for AI SDR selection because the tools that do well at signal detection and timely outreach consistently outperform tools that prioritise message variation over context.

Among the four tools in this comparison, 11x and Artisan invest most heavily in their proprietary signal data. Both platforms ingest funding announcements, hiring patterns, technology changes, and executive movements, then surface accounts where the signal is fresh enough to warrant outreach. AiSDR relies more on user-supplied targeting and uses its AI layer to tailor messaging within a tighter ICP definition. Regie.ai is structured as a content and orchestration layer, so its performance depends heavily on the quality of the signal data and contact lists already flowing through the connected sales engagement platform.

In Leadriver's own testing across client campaigns, we saw meaningful performance variation within each tool depending on setup quality. A well-configured AiSDR campaign with narrow targeting and a strong offer outperformed a loosely configured 11x deployment on reply rate, despite the dramatic price gap. This is consistent with a broader pattern in AI SDR usage. The tools amplify what you put in. Teams with weak ICP definitions and soft value propositions do not get saved by AI, regardless of which platform they buy.

One of the most underreported facts about AI SDR tools is how often they get abandoned. According to sales technology analysts, AI SDR tools churn at 50% to 70% annually, roughly double the turnover rate of the human SDRs they were meant to replace. Gartner's 2026 predictions go further, forecasting that more than 40% of agentic AI projects will be abandoned by 2027 due to rising costs, unclear value delivery, or insufficient risk controls.

The reasons for churn are consistent across platforms. Teams deploy an AI SDR expecting an immediate pipeline boost, discover that the quality of output depends heavily on inputs they had not thought to prepare, and then spend three months tuning before performance improves. By that point, the contract is up, the budget holder has changed, and the tool gets quietly dropped. According to research referenced in Digital Commerce 360, AI agents will channel more than $15 trillion in B2B spending by 2028, which means the market is growing fast even as individual deployments fail.

When evaluating AI SDR tools, churn risk matters as much as launch performance. Annual contracts from 11x and Artisan lock buyers into a twelve-month commitment that may not reflect the actual ramp-up time required. Quarterly billing on AiSDR gives teams an earlier exit window if the tool underperforms. Regie.ai's positioning as a layer on top of existing tools reduces switching cost if the deployment does not deliver, because the underlying sales engagement platform remains in place.

To give a clear comparison, the table below maps each tool across the six criteria that B2B outbound teams most often use when selecting an AI SDR platform. These are pricing and contract flexibility, quality of signal data, multi-channel reach, reply handling, integration with existing stack, and reported reply rate performance based on published case studies and independent reviews.

AiSDR is the right starting point for mid-market B2B teams that want transparent pricing, faster ramp-up, and the option to exit if performance disappoints. It works particularly well for teams that already have a clear ICP definition and a proven offer, because the tool amplifies rather than invents that work. Companies with two to five SDRs considering AI augmentation often find AiSDR the simplest place to test the thesis without committing to an enterprise contract.

Artisan suits mid-market to upper-mid-market teams that want a fully autonomous agent handling both email and LinkedIn, and that are willing to commit to a year-long contract to get there. Its strength is the breadth of data and reply-handling capability, and it generally makes sense for teams whose current outbound motion is inconsistent and who want the platform to enforce discipline across sequencing, cadence, and personalisation.

11x is an enterprise tool and should be evaluated as one. The teams getting real value from 11x typically have deal sizes above $50,000 ACV, dedicated sales engineering support, and a clear sense of which accounts they want to penetrate. The tool is expensive, but in enterprise sales the cost of missing a live buyer in a target account often exceeds the annual contract value. Teams that do not yet have this level of sales maturity will struggle to justify 11x's pricing.

Regie.ai is the right choice for teams that already have a working sales engagement platform such as Outreach or Salesloft and want to add AI content generation and orchestration without replacing their existing workflow. According to adoption data summarised in Autobound's State of AI Sales Prospecting 2026, 89% of revenue organisations have adopted some form of AI, but many still run a hybrid stack. Regie.ai suits this reality better than the full-replacement platforms.

Every AI SDR evaluation eventually collides with the question of whether to keep human reps at all. The honest answer in 2026 is that most B2B teams still need humans, but not as many as they had before. An experienced human SDR in Western Europe or the United States costs between $65,000 and $95,000 per year fully loaded. A well-deployed AI SDR can handle the research, first-touch messaging, and cold follow-up work that previously consumed 60% to 70% of an SDR's time, which means the same team can cover more accounts with fewer reps.

The teams getting this transition right keep their best SDRs and use AI to remove the grunt work from those roles. The teams getting it wrong replace human SDRs wholesale, then discover that qualified replies still need a human to take the first call, and that their AI-generated pipeline converts at a lower rate than their old human-generated pipeline because the qualification work that used to happen in the prospecting conversation has been skipped entirely.

Leadriver's own stance is that AI SDR tools are most valuable when they sit alongside a small, highly trained human outbound team. Our clients typically see the best results when AI handles the first two touches and a human takes over from the first reply onward. This split preserves the quality of the first meeting and avoids the credibility damage that comes from AI continuing a conversation it cannot actually handle.

AI SDR tools can generate outbound volume faster than any human team could manage, which creates a deliverability risk that is often underestimated. Sending thousands of personalised emails from a small number of domains, even with good warm-up, increases the chance of spam filtering and eventual domain blacklisting. The tools in this comparison handle this differently. 11x and Artisan operate their own sending infrastructure and include domain rotation as part of the service. AiSDR typically integrates with user-supplied domains, which gives more control but requires more ongoing management. Regie.ai inherits the deliverability posture of the underlying sales engagement platform.

According to Martal's B2B cold email statistics for 2026, maintaining inbox placement above 80% requires a combination of proper SPF, DKIM, and DMARC configuration, gradual volume ramp-up on new domains, and tight list hygiene to keep bounce rates below 5%. AI SDR tools can help or hurt here depending on how they handle list validation and sending cadence. Teams buying an AI SDR should assume they will need to invest in deliverability infrastructure separately, regardless of which tool they choose. The platform will not save a campaign being sent from poorly configured domains.

Our default recommendation for B2B teams exploring AI SDR tools in 2026 is to start with AiSDR on a quarterly contract, define a narrow ICP, and run a six-week test with a human SDR handling all qualified replies. This approach gives teams a genuine view of whether AI-assisted outbound fits their sales motion without locking in enterprise pricing. If the test works, scaling into Artisan or 11x later is straightforward once the operating model is proven.

For teams already running Outreach or Salesloft successfully, Regie.ai is the better choice because it avoids the disruption of replacing the underlying platform. The content generation improvements alone typically justify the monthly cost if the existing sequences have become stale. For enterprise teams with complex multi-threaded deals, 11x remains the strongest signal-to-engagement platform, but it should only be deployed once the supporting human team has the capacity to follow up on the volume it produces.

The most expensive mistake in AI SDR selection is not choosing the wrong tool. It is treating the tool as a substitute for offer clarity, ICP definition, and message quality. The data from 2026 is unambiguous on this point. Signal-based, tightly targeted campaigns produce reply rates three to five times higher than loosely configured campaigns on the same platform. The tool matters less than the thinking that goes into how it is deployed.

The questions below come up regularly in Leadriver client conversations when teams are evaluating AI SDR tools. The answers reflect 2026 benchmarks and our direct experience running campaigns on each platform.

AiSDR is the cheapest of the four major AI SDR platforms in 2026, with a published starting price of $900 per month billed quarterly. Annual commitments bring the effective monthly price down by roughly 20%. Other tools in the comparison start at $2,400 per month or higher and typically require annual contracts. Reply.io's Jason AI is sometimes mentioned as a lower-cost option at around $300 per month, but it is positioned as a lightweight agent rather than a full AI SDR replacement.

According to 2026 adoption research, 22% of B2B sales teams have fully replaced their human SDR function with AI, while 55% run AI-augmented workflows. Full replacement is technically possible but carries real risks, including lower conversion rates on AI-generated pipeline and higher churn from customers who feel they are not talking to a human. Most mature B2B teams keep their best SDRs and use AI to eliminate research and cold follow-up work, freeing human reps to handle qualified conversations.

The average cold email reply rate across B2B outbound in 2026 is 3.43%. Tightly configured AI SDR campaigns with strong ICP targeting and signal-based triggers can achieve 5% to 8% reply rates. Elite campaigns exceed 10%. Generic cold outreach from any AI SDR tool, without careful targeting, typically produces reply rates between 1% and 3%. The tool matters less than the quality of targeting and offer clarity.

AI SDR tools churn at 50% to 70% annually, roughly double the turnover rate of the human SDRs they replace. The main reasons are slower-than-expected ramp-up, disappointing reply rates, and the realisation that the tool amplifies input quality rather than replacing strategic thinking. Teams that deploy without a clear ICP, a strong offer, or deliverability infrastructure in place usually churn within the first nine months. Gartner predicts more than 40% of agentic AI projects will be abandoned by 2027.

Multi-channel AI SDRs tend to outperform email-only tools for B2B outbound in 2026, particularly for enterprise and mid-market deals where buyer research often happens on LinkedIn before a reply is sent. Tools such as Artisan and 11x include LinkedIn automation alongside email. AiSDR and Regie.ai are primarily email-focused with lighter LinkedIn support. If the target audience actively uses LinkedIn for buying research, a multi-channel tool typically produces higher engagement, though it also adds risk if the LinkedIn automation is not tightly controlled.

Most AI SDR deployments take six to twelve weeks to reach meaningful performance. The first three to four weeks are typically spent on ICP refinement, message testing, and deliverability warm-up. Reply rate improvements usually appear in weeks five through eight once the tool has enough feedback data to optimise targeting and messaging. Teams that expect immediate pipeline in the first month almost always churn, while teams that commit to a structured twelve-week test see far better outcomes.

Small B2B teams can get real value from AI SDRs, but the economics only work for specific setups. The best fit is a team with two to five reps, a clear ICP, and an average deal size above $10,000 ACV. Below that threshold, the monthly cost of an AI SDR tool rarely justifies the pipeline it produces. Small teams with strong offers and narrow targeting often see better outcomes from AiSDR than from enterprise-tier tools, because the lower commitment allows them to test quickly and exit if the economics do not work.
