| Best for | Budget-conscious teams prospecting into the US; Small teams that want data and sequencing in one tool; Building large lists that will be verified separately | RevOps or GTM engineers who will build and maintain custom enrichment workflows; Waterfall enrichment across several data providers; Targeted, lower-volume lists where data quality matters more than cost per row |
| Skip it if | Teams that need reliable direct dials for cold calling; Senders who cannot run a separate verification step; Prospecting outside the US or in niche verticals | Teams that just want a contact database with no setup; High-volume bulk enrichment on a tight budget; Agencies that need predictable per-client costs |
| Pricing (vendor-stated) | Free plan with 900 credits per seat per year. Paid plans billed annually: Basic $49, Professional $79 and Organization $119 (minimum 3 seats) per seat per month; monthly billing costs more (the page says annual saves 24%). 14-day trial on Basic and Professional. Inbound and Advanced Dialer are paid add-ons. | Free plan with 100 data credits and 500 actions a month (tables capped at 200 rows, no phone enrichment).

Data credits start at $0.05 each; bring-your-own API key runs use actions only. 14-day trial. |
Independent users treat Apollo as the budget default: far cheaper than ZoomInfo, with data and sequencing bundled in one place, and good enough for US prospecting if you accept extra cleanup. The recurring complaint is data freshness: users describe stale records, people who left years ago, wrong or switchboard phone numbers and bounce rates that stay high even after Apollo's own verification, plus renewals and credit changes that raised costs. About 40% of the Reddit mentions read as promotional, including a large, coordinated cluster of near-identical comments pitching Prospeo as the Apollo replacement, so this rests on roughly 30 independent opinions.
Users like
- Costs a fraction of ZoomInfo, and users who weigh price against quality call the data good enough for the money[1][2][3][4][5]
- Several users who had both Apollo and ZoomInfo preferred Apollo overall[1][2][3]
- Database, sequencing and dialing live in one tool, which users find simple for early-stage or low-volume outbound[1][2][3]
- Works without major issues for some users, particularly when targeting the US[1][2][3]
Users complain about
- Stale records: users find people who left months or years ago (one found a contact who died 20 years earlier still listed), with bounce rates around 9% even after running lists through a verifier[1][2][3][4][5]
- Phone numbers are a weak spot: inactive, wrong-person or HQ switchboard numbers returned instead of no result, and one user reports half the numbers were unreliable[1][2][3][4]
- Costs have crept up: a long-time customer's renewal tripled after a credit system change, and others say enrichment is expensive for what it returns[1][2][3]
- Coverage thins outside the US and in some niches: it lost to ZoomInfo and Cognism in one team's US and EMEA test, and a health tech team found it missed many people after leaving ZoomInfo[1][2][3]
Independent users largely agree Clay is the most flexible way to run waterfall enrichment and custom research workflows, because it can query many providers and route the results into a CRM. The trade-off is cost and effort: credits burn quickly, the 2026 move to billing every workflow action makes bills hard to predict, and teams say it takes a skilled builder or a dedicated person to get value from it. More than half of the Reddit mentions are promotional, including a cluster of about a dozen r/coldemail comments from May and June 2026 that all pair Prospeo with Clay in the same talking points, plus many replies plugging Clay alternatives such as Bitscale, Floqer, Airscale and pipe0; this review rests on about 20 independent opinions.
Users like
- Waterfall enrichment across many providers: users say it pulls from more sources than single databases like Apollo and fills gaps they would otherwise miss[1][2][3][4][5]
- Flexible enough for custom work once someone learns it: AI account research, hiring signals, CRM imports and middleware between other tools[1][2][3][4][5]
- Costs become manageable for teams that filter lists with cheap signals before enriching, or bring their own provider API keys instead of paying Clay's data markup[1][2][3]
Users complain about
- Expensive: credits burn quickly because it can do so much, and one team cites a $26k quote for what it considered entry-level work[1][2][3][4][5]
- The 2026 pricing change bills every workflow step, HTTP call and CRM push as an action, which users say makes costs hard to predict at agency scale[1][2]
- Steep learning curve: every use case has to be built by hand, and some teams say they would need to hire someone just to run it[1][2][3][4]
- Economics weaken at high volume: users who run it as a bulk data provider find it expensive and suggest reserving it for a filtered or top-priority slice of the list[1][2]
