Apollo
B2B sales platform: contact database, outbound tools, and GTM workflows for 600K+ firms.
Apollo grows fast between ZoomInfo's enterprise wall and Clay's AI speed, while its own ChatGPT and Perplexity connectors hint it may end up as a data pipe rather than the workflow's home.
Apollo is a sales platform that helps companies find business contacts and automate outreach. It has real customers (600,000 companies) and real revenue (around $150-200 million a year growing 40%), so it is not going away soon. The hard part is that ZoomInfo, which is much larger and already trusted by big enterprises, is fighting to keep Apollo out of that upmarket space, and Clay, a newer AI-focused competitor, is growing five times faster by letting artificial intelligence run the outreach workflow directly. The biggest question mark is whether Apollo will remain the main tool salespeople use for these tasks, or whether it becomes just a data source plugged into ChatGPT or Claude where the real work happens, which would make Apollo far easier for customers to replace.
Apollo's next funding round pricing versus the $1.6B mark. A flat or down round would show investors doubt the moat holds against ZoomInfo and Clay.
Enterprise retention and ACV trends after the Pocus acquisition. Churn or high CAC would show the push into ZoomInfo's territory is failing.
- ARR grew from $134M to $150M+
- $100M raised at $1.6B valuation
- Approaching $200M ARR after Pocus deal
- Clay and other AI-native rivals could commoditize the agentic prospecting layer Apollo depends on for per-seat pricing.
- Shipping ChatGPT and Perplexity connectors may reduce Apollo from workflow-owner to interchangeable data-pipe.
- Enterprise push via Pocus acquisition into ZoomInfo's entrenched territory could raise churn and CAC without durable retention.
- Valuation has been unpriced since August 2023's $1.6B mark, leaving unclear whether growth justifies a markup.
- Sales-tech integration layer is a live attack surface, as shown by Salesloft's 2025 Drift breach affecting 700+ organizations.
| Rival | Direction | Evidence |
|---|---|---|
| ZoomInfo | contesting | Apollo bought Pocus in March 2026 to push upmarket into ZoomInfo's enterprise base, which had 439 Gartner reviews vs Apollo's 65 as of 2026 |
| Clay | losing to | Clay grew to roughly $30M ARR in 2024 at about 500% YoY, outpacing Apollo's ~40% YoY growth in the same AI-native GTM category |
| OpenAI/ChatGPT platform | contesting | Apollo launched a ChatGPT app in April 2026, betting it can stay relevant as workflows shift into foundation-model assistants |
| HubSpot | contesting | Apollo added CRM-lite features by 2025 to compete against HubSpot's broader suite, per Sacra's May 2025 analysis |
| Salesloft | gaining on | Salesloft suffered a Drift product breach affecting 700+ organizations in August 2025, a reputational setback for a direct sales-engagement rival |
- Is Apollo.io profitable in 2026?
- Apollo has not disclosed profitability. It is privately held and reported revenue grown more than 5x since its 2023 Series D (vendor-claimed, May 2026), with ARR approaching $200M in March 2026 per tech press, but no net income or margin figures have been made public.
- Who owns Apollo.io?
- Apollo.io is privately held and VC-backed. Its $100M Series D in August 2023 at a $1.6B valuation was led by Bain Capital Ventures with Sequoia, Tribe Capital, and Nexus Venture Partners participating. Founder Tim Zheng became Chairman in February 2026 when COO Matt Curl took over as CEO.
- Could AI replace Apollo.io?
- Apollo's core value, prospecting and outreach automation, is exactly what AI agents automate, and Apollo shipped ChatGPT and Perplexity connectors plus an MCP server by April 2026, tacitly acknowledging workflows may migrate to foundation-model platforms rather than staying inside Apollo's own product.
- How fast is Apollo.io growing?
- Sacra estimated Apollo's ARR grew from about $96M in 2023 to $134M by end of 2024 and crossed $150M by May 2025, roughly 40% YoY. Tech press reported it was approaching $200M ARR by March 2026 when it acquired Pocus.
- Who is Apollo.io's biggest competitor?
- ZoomInfo is the entrenched enterprise incumbent, holding 439 Gartner Peer Insights reviews versus Apollo's 65 as of 2026, showing deeper enterprise penetration. Clay, an AI-native rival, reported roughly $30M ARR in 2024 growing about 500% YoY, directly contesting Apollo's AI-workflow positioning.
- What is Apollo.io's current valuation?
- Apollo's last publicly disclosed valuation was $1.6B, set in its August 2023 Series D funding round of $100M led by Bain Capital Ventures. No new priced round has been publicly disclosed since, despite revenue reportedly growing several-fold in that period.
