Full review →What is AiSDR?
AiSDR is a dedicated AI sales agent that runs the full outbound cycle, from finding in-market buyers using real-time signals to writing personalized email and LinkedIn messages and booking meetings. It draws on a 700M+ contact database, sends through your own Gmail or Outlook, and includes unlimited seats at every tier. It is built to replace the repetitive parts of an SDR role rather than to equip a human team.
What is Amplemarket?
Amplemarket is an all-in-one outbound platform that replaces a separate database, sequence tool, dialer, and inbox warmer with one vendor. It pairs a 200M+ AI-verified contact database with multichannel sequences (email, LinkedIn, phone), email warmup, bi-directional Salesforce and HubSpot sync, and the Duo AI copilot. It targets mid-market teams (roughly 10 to 50 reps) that want to consolidate their outbound stack.
Key differences at a glance
Product philosophy: AiSDR is an autonomous AI SDR agent that runs outreach for you with near-zero human input. Amplemarket is a human-operated all-in-one platform where reps run sequences with the Duo AI copilot assisting, not replacing, them.
Channels: AiSDR covers email and LinkedIn only, with no calls, SMS, or WhatsApp. Amplemarket adds a built-in phone dialer for cold calling alongside email and LinkedIn, making it genuinely multichannel.
CRM integrations: AiSDR integrates natively with HubSpot only. Amplemarket offers bi-directional Salesforce and HubSpot sync on all plans, with Zapier for other CRMs, so it fits Salesforce-based sales orgs far better.
Pricing model and seats: AiSDR bills on message volume with unlimited seats included at every tier. Amplemarket bills per user on annual-only contracts (2 users at Startup, then $300 to $400 per extra seat), so cost scales with headcount.
Contact database: AiSDR ships a larger 700M+ contact database with real-time intent signals feeding autonomous prospecting. Amplemarket has a 200M+ AI-verified database across 20M companies with advanced filters, sized for rep-driven targeting.

Amplemarket Amplemarket has no free plan and sells on annual contracts only. Startup is the sole published tier at $600/month (billed annually, $7,200/year) with 2 users and a 10,000 shared-credit monthly allocation. Growth and Elite are custom quoted, typically $2,000 to $5,000/month per public reports. Extra users run about $300 to $400/month each, so a small team pays well above the $600 base. Verified June 2026 from www.amplemarket.com.
AiSDR has the lower published entry once you add reps, because seats are unlimited and pricing scales on message volume rather than headcount. Amplemarket looks cheaper at the $600 headline but includes only 2 users, is annual-only, and jumps to custom $2K to $5K quotes for the Growth features most teams actually want. Neither offers a free plan or self-serve trial. For team-by-team cost modelling, use our AI Cost Calculator.

Bottom line: AiSDR vs Amplemarket
AiSDR and Amplemarket both automate outbound but sit at opposite ends of the autonomy spectrum. AiSDR is a done-for-you AI SDR that prospects and writes on its own across email and LinkedIn, with unlimited seats and a bigger database, best for teams that want outbound to run itself.
Amplemarket is a done-with-you platform that consolidates the whole outbound stack, adds calling and deep Salesforce sync, and layers in the Duo copilot, best for mid-market teams tired of juggling five vendors and willing to commit annually. Match the tool to whether you want automation (AiSDR) or consolidation (Amplemarket).
🔄 Switching? Keep in mind
Migrating from Amplemarket to AiSDR means moving from a rep-run multichannel stack to autonomous email and LinkedIn outreach; export your lists and reconnect HubSpot, but plan to drop cold calling. Moving from AiSDR to Amplemarket adds a dialer and Salesforce sync but shifts work back to your reps and requires an annual commitment.
Frequently asked questions
Is AiSDR or Amplemarket cheaper?
It depends on team size. Amplemarket has the lower headline at $600/month, but that is annual-only and includes just 2 users, with extra seats at $300 to $400 each and Growth features priced at a custom $2,000 to $5,000/month. AiSDR starts at $900/month but includes unlimited seats and scales on message volume, so for teams of several reps AiSDR is often the lower effective cost. Neither has a free plan.
What is the main difference between AiSDR and Amplemarket?
AiSDR is an autonomous AI SDR that runs email and LinkedIn outreach end to end with minimal human input. Amplemarket is an all-in-one platform where human reps run multichannel sequences (including phone) with an AI copilot, Duo, assisting them. AiSDR automates the SDR role; Amplemarket consolidates the outbound tool stack.
Does either tool offer cold calling?
Only Amplemarket. It includes a built-in phone dialer for cold calling alongside email and LinkedIn on its higher tiers. AiSDR is limited to email and LinkedIn and does not support calls, SMS, or WhatsApp, so teams that rely on outbound calling should choose Amplemarket.

Neither offers a free plan or a self-serve trial. AiSDR sells its Explore plan from $900/month with no public trial. Amplemarket offers trials only through its enterprise sales process on annual contracts. If you want a free tier or no-sales-call trial, Apollo.io, Reply.io, or Instantly are better starting points.

AiSDR, with a 700M+ contact database enriched with real-time intent signals that power its autonomous prospecting. Amplemarket database is 200M+ AI-verified contacts across 20M companies.
