AiSDR: Best for signal-based outbound and inbound follow-ups

AiSDR is the best fit for B2B SaaS teams that want to reach buyers when they show intent and answer inbound leads within minutes. AiSDR finds prospects through live signals like job changes, new hires, and funding rounds. Its Team plans add LinkedIn engagement and website visitor signals. AiSDR researches each lead before writing, then runs email, LinkedIn, and call steps in one sequence.

AiSDR connects to HubSpot or a website intake form for inbound lead follow-up, then qualifies each new lead and replies within minutes. Firms that contact a lead within an hour were nearly 7 times as likely to qualify it as firms that waited an hour longer.

AiSDR is built to think before it sends, and teams can run replies in co-pilot mode so a person approves them first. AiSDR's pay-as-you-go pricing is $1.50 per person with no monthly fee. Team plans, built for teams contacting 1,000+ people a month, add Salesforce integration and a dedicated GTM engineer.

11x: Best for high-volume enterprise-scale outbound

11x is the best fit for larger B2B SaaS teams running outbound across several markets, languages, and personas. 

11x sells 2 digital workers: 

1. Alice – an outbound AI SDR

2. Julian – an inbound agent that qualifies leads by phone, chat, and text 

Every Alice plan includes 11x-managed Gmail mailboxes, domain setup, warmup, inbox rotation, and bi-directional CRM sync.

11x's pricing and terms are built for enterprise buyers. The Alice Growth plan starts at $3,750 a month billed annually, for up to 5 users and 2,000 new prospects a month. The Pro plan adds outreach in 105+ languages, and the Enterprise plan adds SSO, a custom DPA and SLA, and a forward-deployed engineer. Smaller teams that can't commit to a high cost or annual contract can compare 11x alternatives.

Valley: Best for LinkedIn-first motions

Valley is the best fit for B2B SaaS teams that book most of their meetings through LinkedIn. Every Valley plan includes prospecting, qualification, research, and personalized LinkedIn outreach. Valley users review, edit, and approve drafts before anything goes out, and they set the sending schedule and follow-up steps.

Valley's Starter plan costs $199 per seat a month, or $149 billed quarterly, and covers LinkedIn only. Email starts on the Plus plan at $299 per seat a month, or $249 billed quarterly, with 1,000 email messages per seat each month. 

Any LinkedIn-first motion also needs a plan to avoid LinkedIn account restrictions as outreach grows.

How to choose the right AI SDR for your team

The right AI SDR is the one built for the channel and contract terms your team already works with. 

Here's how the 3 options compare.

Beyond channel, check 3 things before you sign:

• Whether the tool targets buyers by intent signals

• Whether a person can review messages before they send

• Whether the contract length fits your budget

The AI SDR buyer's guide covers the full checklist. These AI SDR red flags help you rule out weak vendors early.

In AiSDR's State of AI SDR Industry Report 2026, the best implementations landed first qualified meetings within 7-14 days and pipeline opportunities within 8 weeks. Whichever AI SDR you choose, ask the vendor how its onboarding plan gets you to that time-to-results benchmark.
