Most tools on this page charge for credits. The credit rules matter as much as the plan price. Clay has a free plan, then Launch from $167/mo and Growth from $446/mo. It uses two credit types, actions and data credits, which makes costs hard to forecast. Persana AI sells credits by the year, with a free plan of 50 credits and Starter at $68/mo billed yearly. Its credits roll over on paid plans.
Apollo.io charges per seat plus credits. It has a free plan with no time limit, Basic at $65/user/mo ($49/user/mo billed yearly) and Professional at $99/user/mo. Its credits reset each billing cycle. Instantly sells outreach plans and lead credit plans separately at $47/mo each. Bundles with both start at $94/mo ($85/mo billed yearly).
The AI SDRs on this page price by how many leads they source and research. AiSDR starts at $250/mo for 200 researched contacts. Alice by 11x starts at $3,750/mo billed yearly for 2,000 new prospects a month. Ava by Artisan is custom pricing based on lead volume, mailboxes and dialer seats. Clay, Apollo.io and Persana AI have free plans and Instantly has a 14-day free trial with no credit card.
We check whether a tool brings its own B2B contact database or pulls from many data providers through waterfall enrichment.
We look at what the AI agent researches on its own, such as Claygent web research or Persana AI's Quantum AI Research Agent.
We note which actions use credits and whether unused credits roll over, reset or expire.
We record whether you can start free and what the free plan actually includes.
We check whether the tool also sends outreach or only hands you an enriched list to use elsewhere.
