Apollo.io vs Gong

Apollo.io is a sales intelligence and engagement platform from San Francisco that combines a B2B database of more than 270 million contacts and tens of millions of companies with the tools to reach them. Many startups use it as their prospecting data source, outbound tool and, at first, a lightweight CRM, all in one subscription.

Prospecting starts with filters for title, seniority, industry, headcount, technologies, funding and buying intent, and a Chrome extension surfaces emails and phone numbers on LinkedIn and company websites. Contacts flow into sequences that mix automated emails, call tasks and LinkedIn steps, with a built-in dialer, call recording, meeting scheduler, enrichment of existing CRM records and AI that researches accounts and drafts personalized messages. Usage runs on credits for emails, mobile numbers and exports. The free plan is unusually generous for a data vendor, and paid plans are priced per user per month, rising through Basic and Professional tiers to a Custom plan for larger teams.

Apollo fits startups, SMB sales teams and founders doing outbound who need data and sequencing at a fraction of ZoomInfo's price. Email accuracy is generally good, mobile numbers are weaker, and teams must manage sending limits and domain health to protect deliverability. ZoomInfo offers deeper enterprise data, Clay is better for multi-source enrichment and research workflows, and Instantly or lemlist focus on outreach volume and personalization. Coverage of Turkish companies exists but is thinner than for the US and Western Europe.

Gong is a revenue intelligence platform founded in 2015 by Amit Bendov and Eilon Reshef, with roots in Israel and headquarters in San Francisco. It records and transcribes sales calls and video meetings, captures email activity, and uses AI to analyze those conversations so revenue teams can see what is really happening in their deals rather than relying on CRM fields that reps fill in by hand.

The platform spans several products: conversation intelligence with searchable transcripts, trackers for topics such as competitors and pricing, and coaching scorecards; deal boards that flag risk based on engagement; Gong Forecast, which uses activity signals to improve forecast accuracy; and Gong Engage, which adds sequences and AI-drafted outreach. AI briefers summarize accounts before calls and answer questions about deals. Pricing is quote-based, typically an annual contract combining a platform fee with per-seat licenses.

Gong suits mid-market and enterprise B2B sales organizations with managers who will actually coach from the data, and revenue leaders who want forecasts grounded in buyer behavior. For small teams it is usually overkill: the platform fee and annual commitment make lighter note-takers such as Fathom, Fireflies or Avoma far cheaper. Clari competes most directly on forecasting, Salesloft and Outreach on sales engagement, and Chorus by ZoomInfo is the longtime conversation intelligence rival.
