HitHorizons vs Apollo.io: Which Data Tool Wins? (2026)

HitHorizons vs Apollo.io: Which Data Tool Wins? (2026)

Poor data costs companies roughly $12.9 million annually. So when you're weighing HitHorizons against Apollo.io, picking the wrong tool has real consequences.

Here's the thing: these two don't actually compete. HitHorizons is a European company database built for firmographics and enrichment. Apollo.io is a global sales engagement platform with sequences, a dialer, and a massive contact database. Comparing them is like comparing a census bureau to a cold-calling machine - they solve fundamentally different problems, and understanding that distinction will save you months of frustration.

30-Second Verdict

Pick HitHorizons if you need registry-sourced European company firmographics for CRM enrichment or market research - and you don't need a contact-first outbound tool.

Pick Apollo.io if you need an all-in-one outbound platform with sequences and a dialer, primarily targeting North America.

If your ICP includes European decision-makers and you care about verified emails plus direct dials, you'll need a dedicated provider for EU contact data. HitHorizons is company-first, and Apollo's EMEA coverage is consistently its weakest link.

HitHorizons at a Glance

HitHorizons covers 80M+ companies across 50 European countries and the UK, with deep coverage in the UK (7.8M companies), France (7.4M), Spain (4.7M), Germany (3M), and Italy (2.7M). Founded in 2019 in Bratislava with a team of roughly 15, it's a focused operation that does one thing and does it well.

The product ships as a web-based Screener with a 50,000-record export limit, plus an API for integrating company data into CRM/ERP and data visualization tools. Everything revolves around company-level enrichment - industry, SIC code, sales figures, employee counts, identifiers like VAT numbers, and more. No contact emails. No phone numbers. Just clean firmographic data.

Pricing is quote-based. Expect roughly EUR 3k-20k/year depending on seats and API usage. The single verified review on Datarade gives it a 5.0 rating, with the buyer noting the data helped them avoid companies that had "disappeared from the market years ago" - a real concern when prospecting from stale registries.

Apollo.io at a Glance

Apollo bundles everything outbound teams need into one platform: 275M+ contacts, 60M+ companies globally, built-in sequences, a dialer, and task management. Over 500,000 companies use it, and the free tier makes it easy to kick the tires.

Pricing starts at $49/user/month (annual) for Basic, scaling to $79 for Professional and $119 for Organization (minimum 3 seats). The Free tier gives you 5 mobile credits/month and 10 export credits/month - enough to test, not enough to run campaigns.

The credit system is where things get tricky. Basic gives you 75 mobile credits per month; Professional bumps that to 100; Organization tops out at 200. Burn through them and you're paying $0.20/credit with a 250-credit minimum, which adds up fast for teams doing heavy phone outreach.

We've tested Apollo's data extensively, and the accuracy numbers tell a clear story. Overall accuracy hovers around 65%, with bounce rates running 15-25%. North American coverage is solid. EMEA and APAC coverage is significantly weaker - phone numbers often route to main lines, and EU accuracy is consistently flagged as the weak link by users on r/sales and outbound communities.

If you're trying to fix deliverability issues caused by bad lists, start with email bounce rate benchmarks and remediation.

Feature-by-Feature Comparison

These tools serve different jobs. HitHorizons tells you which European companies exist and what they look like. Apollo helps you contact people and run sequences. Choosing between them is really about choosing which problem you're solving first.

When to Choose Each Tool

Choose HitHorizons if...

You need European company firmographics at scale - industry codes, employee counts, revenue, VAT identifiers - for CRM enrichment, market sizing, or territory planning across EU/UK markets. The Screener plus API workflow is built for teams that want to pipe clean company data into existing systems, not for teams that need to send cold emails tomorrow.

Skip HitHorizons if you need contact-level data. It doesn't provide emails, phone numbers, or individual profiles. That's not a flaw; it's just not what the product does.

If you're building segmentation around company attributes, see firmographic filters.

Choose Apollo.io if...

You're running outbound campaigns primarily targeting North America and want sequences, a dialer, and contact data in one platform. The self-serve pricing and free tier make it easy to get started, and the workflow integration is genuinely good for teams that live inside one tool.

Skip Apollo for European outreach unless you're prepared to verify every contact through a second provider. We've seen teams burn through credits and domain reputation trying to make Apollo's EMEA data work at scale. It doesn't.

The Gap Both Tools Leave Open

HitHorizons is company-first. Apollo is contact-first but weak in Europe. That leaves a real gap for teams whose ICP includes European decision-makers, and we've watched plenty of teams waste quarters stitching two mediocre workflows together to cover it.

Prospeo fills that gap. Its database covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers, refreshed on a 7-day cycle. You get 30+ search filters - including buyer intent powered by Bombora and technographics - without credit walls or quote-based contracts. For teams prospecting across Europe, pairing HitHorizons' firmographic depth with Prospeo's verified contact data produces a workflow that neither tool delivers alone. One of our customers, Meritt, saw bounce rates drop from 35% to under 4% after switching their contact data layer, tripling their pipeline from $100K to $300K per week.

FAQ

Does HitHorizons provide email addresses or phone numbers?

No. HitHorizons is a company database focused on firmographics - industry, employee count, revenue, SIC codes - across Europe and the UK. For verified personal emails and direct dials, pair it with a dedicated contact data provider that covers European professionals and refreshes data weekly rather than monthly.

Is Apollo.io accurate for European contacts?

Expect 15-25% bounce rates overall, with EMEA accuracy performing worse than that range. European phone numbers frequently route to switchboards rather than direct lines. If EU outbound is your priority, verify Apollo contacts through a second provider or use a platform with stronger European coverage from the start.

Can you use HitHorizons and Apollo.io together?

Yes - HitHorizons for European company identification and Apollo for North American contact data and outreach. But Apollo's European contact accuracy underperforms its NA data by a wide margin. Teams targeting EU decision-makers often get better results pairing HitHorizons with a contact provider that refreshes data weekly, rather than relying on Apollo's EMEA coverage alone. Let's be honest: if you're sending cold emails to European prospects with 20%+ bounce rates, you're damaging your domain reputation faster than you're building pipeline.
