Apollo.io
|
AI-powered sales engagement platform combining B2B contact data, outreach automation, and CRM sync in one dashboard.
What Is Apollo.io?
Apollo.io is a sales intelligence and engagement platform built for teams that are tired of stitching together a data vendor, an email tool, and a CRM just to run outbound. It combines a database of over 244 million contacts with built-in email sequencing, a dialer, and native CRM sync, all inside one login.
Most sales stacks split prospecting into two separate jobs. One vendor sells the contact data, another tool sends the outreach, and someone on the team ends up manually keeping both systems in sync so records don’t drift apart. Apollo collapses that into a single workspace instead, with bidirectional sync to Salesforce and HubSpot so enriched contact records update automatically without a CSV export in sight.
What makes Apollo stand out from a plain contact database is how much sits on top of the data itself: sequences for multi-step outreach, a Chrome extension that reveals verified emails and phone numbers on LinkedIn and company sites, a built-in dialer with call recording, and filters for job changes, funding events, and technographic signals. For a five-person startup sales team, that’s the difference between paying for four separate subscriptions and paying for one.
Apollo.io AI Features
Apollo’s AI layer sits directly on top of its contact data rather than bolted on as an afterthought. The AI Research Agent pulls together account context before a call, drafts follow-up emails based on prior conversation threads, and flags accounts that have gone cold so reps aren’t manually checking activity logs every morning.
Apollo has publicly stated this feature drives a meaningful lift in meetings booked, and the platform won a 2026 MarTech Breakthrough Award for AI-powered sales tools. Treat vendor-reported performance numbers as a starting point rather than gospel, since they aren’t independently audited, but the underlying workflow is genuinely useful: reps spend less time context-switching between a CRM tab, a LinkedIn tab, and an email draft, and more time actually talking to prospects.
Apollo.io Pricing Plans
Apollo starts with a free-forever plan that doesn’t require a credit card. Paid plans run Basic at $49 per user per month billed annually ($59 monthly), Professional at $79 ($99 monthly), and Organization at $119 ($149 monthly, three-seat minimum).
| Plan | Annual | Monthly | Credits/Year |
|---|---|---|---|
| Free | $0 | $0 | 900 (75/mo) |
| Basic | $49/user | $59/user | 30,000 |
| Professional | $79/user | $99/user | 48,000 |
| Organization* | $119/user | $149/user | 72,000 |
*3-seat minimum
Most solo founders and two-person teams get by comfortably on Basic. Once you add a dialer to the workflow or need A/B testing on sequences, Professional tends to be where teams actually land. You can start on Apollo’s free plan and upgrade only once you’ve confirmed the data coverage fits your market, which is the safer order to do it in.
How Apollo.io Credits Work
Credits are where new users get caught out, mostly because the sticker price doesn’t tell you anything about consumption. Different actions cost different amounts, and unused credits don’t roll over between billing cycles on any plan, so a slow month doesn’t bank savings for a busy one.
| Action | Cost |
|---|---|
| Email reveal | 1 credit |
| Phone number reveal | 8 credits |
| Data enrichment | 1-8 credits |
| AI Research run | 1 credit |
| Dialer | 2 credits/minute |
| International Dialer | Varies by region |
Here’s what that looks like in practice: a rep who pulls 50 email addresses and 20 mobile numbers in a single week burns through 210 credits just on reveals, before a single AI Research run or dialer minute gets counted. On Basic’s 30,000 annual credits, that’s sustainable for one active rep. Add a second rep doing the same volume and Professional becomes the more realistic tier.
Apollo.io vs. ZoomInfo, Hunter.io, and Instantly
Apollo gets compared to a wide range of tools because it does a wide range of things. How it stacks up depends entirely on which piece of the workflow you’re trying to replace.
- vs. ZoomInfo: Apollo is far more affordable and publishes its pricing openly instead of gating it behind a sales call. ZoomInfo wins on raw data depth for large enterprise teams with the budget to match, typically starting around $15,000 a year.
- vs. Hunter.io: Hunter is a focused email finder and nothing more. Apollo is a full platform, so the two solve genuinely different problems depending on how much of your workflow you want consolidated into one tool.
- vs. Instantly: If you already have a data source and just need a dedicated sending tool built for deliverability, Instantly is often the better fit rather than relying on Apollo’s built-in sequencer.
Who Should Use Apollo.io?
Apollo fits best for:
- Startups and early-stage sales teams that need contact data and outreach in one place without a five-figure annual contract
- Solo founders doing their own prospecting who want a genuine free plan to validate the data before paying
- SMB sales teams of 3-10 reps who want CRM enrichment and sequencing without managing three vendor relationships
- Teams that value transparent, published pricing over a sales-gated quote process
Larger enterprise teams running heavy account-based marketing or phone-first outbound at real scale tend to outgrow Apollo’s data depth within a year or two. They typically move toward ZoomInfo or Cognism instead, trading Apollo’s affordability for deeper, more accurate enterprise data. If your team fits the profile above, though, Apollo’s free plan is a low-risk way to find out if the data covers your market before you commit to a paid tier.

Apollo.io FAQ
Is Apollo.io free?
Yes. The Free plan includes contact search, 75 credits a month, and basic sequencing through Gmail or Microsoft accounts, with no credit card required to start.
Is Apollo.io a CRM?
No. It enriches and feeds data into CRMs like Salesforce and HubSpot through bidirectional sync, but it isn’t built to replace one.
How accurate is Apollo’s data?
Apollo cites high internal verification rates. Independent testing commonly reports higher real-world bounce rates, so pairing exports with a separate verification step is common practice among heavy users.
How many credits does a typical rep need per month?
It depends on volume, but a rep pulling roughly 200 emails and 80 phone numbers a month uses around 840 credits on reveals alone, before AI Research or dialer usage. Basic’s 2,500 monthly credits (30,000/year) comfortably covers one moderately active rep.
Does Apollo.io work with LinkedIn?
Yes, through a Chrome extension that reveals verified contact details directly on LinkedIn profiles and company pages while you browse.
What is Apollo’s AI Research Agent?
It’s a built-in AI assistant that pulls account context ahead of calls, drafts follow-up emails from prior conversation threads, and flags accounts that have gone quiet so reps don’t have to manually track activity.
Can I cancel Apollo.io anytime?
Monthly plans can be cancelled before the next billing date. Annual plans need 30 days’ written notice before renewal, per Apollo’s Terms of Service, and self-serve cancellation isn’t available on every account type.
