Apollo vs. harp: Which Is Right for Your Team?
Sales intelligence platform vs. autonomous AI team - data and tools vs. execution.
TL;DR
Apollo is the all-in-one sales intelligence platform - 275M+ contacts, engagement tools, and analytics. It's the default prospecting tool for thousands of sales teams. But "all-in-one" means all the tools in one place - you still do the work. Build lists. Write sequences. Manage campaigns. harp's agents do that work for you. Same goal, fundamentally different model.
Apollo vs. harp: At a Glance
| Apollo | harp | |
|---|---|---|
| Pricing | Free – $99/user/mo (+ credits) | $39 – $249/mo flat |
| Target audience | Sales teams of all sizes | Founders & small teams (3–20) |
| Setup time | 30 minutes – hours | ~10 minutes |
| AI approach | AI for scoring, writing assist | AI-native autonomous agents |
| Autonomy | Low - humans build lists and sequences | High - agents execute, you approve |
| Core model | Sales intelligence + engagement tools | Autonomous GTM team |
Pricing
Apollo's free tier is generous: 10,000 records, basic sequences, and limited AI features. Paid plans run $49–$99/user/month on annual billing, with a credit system for contact exports and enrichment. For a 3-person team on the Professional plan, that's $297/month - before credits.
harp is $39/month flat. No per-user pricing, no credits to manage, no per-contact charges. For small teams watching every dollar, harp's predictable pricing eliminates the "how many credits did we use?" anxiety.
AI & Autonomy
Apollo has added AI features - email writing assistance, lead scoring, and smart filters. These make the platform more efficient, but the core workflow remains manual: you search the database, build a list, create a sequence, write the emails (AI-assisted or not), and launch the campaign. You operate the tools.
harp inverts this. Prospector searches for prospects matching your ICP - you don't build lists. Qualifier scores them - you don't set up scoring rules. Reacher drafts personalized emails - you don't write sequences. The AI operates. You approve.
The difference: Apollo gives you a database and tools. harp gives you results.
Data Advantage
Apollo's 275M+ contact database is a genuine competitive advantage. It's one of the largest B2B databases available, with strong email and phone accuracy. If your primary need is access to contact data, Apollo is a top choice.
harp doesn't compete on database size. Instead of giving you a list to work through, harp's Prospector finds leads that match your specific ICP - curated, not bulk. The tradeoff: less data access, more targeted results. Quality over quantity.
Who Should Choose What
Choose Apollo if you have SDRs who need a powerful prospecting platform. If database access and engagement tools are what your sales team requires. If you want granular control over list building, sequences, and campaign management. Apollo is the industry standard for sales intelligence.
Choose harp if you don't have SDRs and need the SDR function handled autonomously. If you'd rather have AI agents find, qualify, and reach out to prospects than do it yourself through a platform. If predictable pricing and zero manual campaign management matter more than database size.

The Bottom Line
Apollo is the best sales intelligence platform available - a 275M contact database with solid engagement tools. If you have salespeople who need data and tools, Apollo delivers. harp is for teams that need the salespeople, not the tools. If your bottleneck is data access and campaign management, choose Apollo. If your bottleneck is capacity - you need more outbound happening but don't have the people - choose harp.
Frequently Asked Questions
Does harp use Apollo's data?
No. harp uses its own discovery engine. The Prospector agent finds leads based on your ICP description, independent of any third-party database.
Can Apollo's AI do what harp does?
Apollo's AI assists with email writing and lead scoring, but the platform requires humans to build lists, create sequences, and manage campaigns. harp's agents handle these autonomously.
Is Apollo better for larger teams?
Yes. Apollo scales well for sales teams of 10+ with per-user pricing that includes database access. harp is optimized for founders and small teams (3-20) who need autonomous execution rather than a self-serve tool stack.
What about Apollo's free tier?
Apollo's free tier is genuinely useful for exploring the database. But free access to 275M contacts doesn't include anyone to contact them. harp's $39/month includes the agents that do the work.
