Apollo.io is a sales intelligence and engagement platform — combining a 270M+ B2B contact database with sales engagement automation, AI email writing, and conversation intelligence for sales teams. AI capabilities include AI-generated email personalisation — generating outreach emails personalised to prospect's company news, LinkedIn activity, and job role context. AI Sequence Suggestions recommend the optimal outreach cadence — email, call, and LinkedIn touch sequence templates based on prospect characteristics and deal type. Prospect Discovery uses AI filtering — finding ideal prospects from the 270M+ contact database using company, role, technology, and behaviour filters. Email Deliverability tools protect sender reputation — email warming, spam testing, and deliverability analytics ensuring outreach reaches inboxes rather than spam folders. Conversation Intelligence (Chorus integration) records and transcribes sales calls — identifying key moments, competitor mentions, and action items from recorded conversations. Intent Signals identify companies showing research activity — prioritising outreach to accounts actively evaluating relevant categories. CRM Sync with Salesforce and HubSpot keeps prospect data current — enriching CRM records with updated Apollo contact and company data. With 1M+ users including at startups and mid-market companies, Apollo validates as the most accessible sales intelligence and engagement platform.
Apollo.io AI runs as llm assistant software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and chrome extension, with API access for teams that want to embed it into their own products.
