Best AI SDR tools for lead-gen agencies
Agencies add client mailboxes, LinkedIn senders and teammates faster than a single in-house team does, so an AI SDR charged per seat gets expensive quickly. This list covers only AI SDR products with a published self-serve price whose plans are not charged per user: flat plans with unlimited users or senders, plans sized by contacts or credits, and per-prospect pricing. The 'How it's charged' column says what each plan scales with, taken from the vendor's own pricing page.
For small teams: see every small team friendly sales tool (free plan or free trial, self-serve, $50/mo or less) and your first sales tool stack for under $100/month.
How this list works: Only AI SDR products with a published self-serve price that is not charged per seat. Ordered by lowest published entry price (annual rate where the vendor shows one); ties alphabetical; per-prospect pricing last. Pricing verified against vendor pages (latest check ). No placement here is paid. Methodology.

FAQ
Why does per-seat vs per-plan pricing matter for an agency?
An agency usually runs several clients' campaigns with a small team, adding mailboxes, LinkedIn senders and occasional collaborators per client. A per-seat AI SDR multiplies its price by every user, while a plan sized by senders, contacts, credits or usage lets you add people without adding seats. Check what each plan caps (contacts, credits, senders) in the price column before comparing entry prices.
Which AI SDRs include unlimited users or team members?
On their own pricing pages, Persana AI lists unlimited users, Origami lists unlimited team members on every plan, and Rox's Teams plan is priced for the whole team with unlimited users. Salesforge includes unlimited email senders on every plan, and Emailchaser includes unlimited mailboxes on every plan.
Which AI SDRs were left out, and why?
AI SDRs charged per seat or per user (Unify, Regie.ai's Team plan, Valley, Buzz.ai and Reply.io), Amplemarket (plans include a set number of users on an annual term) and tools that publish no price (11x, Artisan, Topo, Jazon, Alta, Conversica). They are compared in our best AI SDR tools list and the AI SDR pricing guide.
What else does an agency AI SDR setup cost?
Most cold outreach setups also pay for sending mailboxes and domains, warmup and contact data, unless the AI SDR plan includes them (Emailchaser includes unlimited mailboxes with warmup; Origami sells done-for-you inboxes as an add-on). See our email warmup and cold email inbox pricing and email finder pricing pages for those costs.
