AiSDR is an AI sales agent that automates prospecting, multichannel outreach, and reply handling across email and LinkedIn to book qualified meetings. It's backed by Y Combinator and used by 250+ companies. Plans start at $250/month for solo users, with the popular Explore tier at $900/month billed quarterly.
AiSDR earns its price tag by doing what most outbound tools don't: qualifying replies and handling objections instead of just sending messages. The quarterly commitment on Explore and Scale is a real trade-off, and the jump from Solo's $250 to Explore's $900 leaves no middle ground, so match the tier to your actual team size before committing.

Apollo.io earns its popularity by solving a real problem: buying separate data and outreach tools gets expensive fast. For startups and SMB teams, a genuine free plan, transparent pricing, and built-in sequencing are hard to beat. The main trade-off is data accuracy, which trails premium providers, so pair Apollo with a verification step before sending at volume.
