Conversica

Conversica is one of the longest-running AI SDR companies, with more than 15 years of enterprise deployments. Its Revenue Digital Assistants hold two-way, human-like conversations with leads across email, SMS and website chat.

The focus is on making sure every lead gets a follow-up. The assistants engage new inbound leads, qualify them and hand warm ones to sales, and they re-engage dormant leads and stalled opportunities that human teams rarely have time to chase. Conversica says its platform has processed more than 1.5 billion conversations for over 2,000 teams, and its long track record means established compliance frameworks and procurement-friendly credentials, which matter to larger companies. It is listed on the Salesforce AppExchange.

Conversica suits mid-market and enterprise organisations with large lead volumes, including marketing teams that want every lead followed up without adding headcount.

Pricing is custom and not published. Reported pricing starts at about $2,999 a month, or roughly $36,000 a year before implementation, depending on conversation volume and integrations.
