Ampliz vs Exellius: Which B2B Data Provider Should You Pick?
You're building an outbound list, someone on your team mentioned Ampliz, and then you stumbled across Exellius. Now you're comparing the two to figure out which one deserves your budget - and there's no head-to-head comparison anywhere online. These are two niche B2B data providers with a combined 10 public reviews between them. Let's fix that.
30-Second Verdict
Pick Ampliz if you're prospecting into healthcare or APAC markets. That's its wheelhouse.
Pick Exellius if you need general B2B outbound volume. It gives you 60x more credits per dollar than Ampliz at roughly the same price point.
What Is Ampliz?
Ampliz is a B2B data provider that's carved out a niche in healthcare and APAC markets. Its database covers 400M+ contacts across 16 countries, and it's used by 5,000+ companies. On Reddit's r/gtmengineering, it shows up in conversations about vertical GTM data providers - the same thread pegs Ampliz at roughly $29M in revenue, placing it alongside Definitive Healthcare as a serious vertical data player.
The platform carries a 4.2/5 on G2 from 7 reviews. Users praise its DACH region data quality and verified emails, while flagging gaps in coverage for smaller German companies and an outdated UI.
What Is Exellius?
Exellius positions itself as an all-in-one B2B data platform - lead discovery plus email validation - with phone intelligence, technographics, enrichment, and an API/CRM integrations layer. It covers 100M+ verified contacts and holds a 4.9/5 on Datarade from 3 reviews. Its own site also lists ratings across G2, Capterra, and Trustpilot in the 4.4-4.8 range, though review counts aren't publicly disclosed.
The interesting differentiator is Amazon seller data - a niche dataset covering 1M+ seller contacts you won't find in most B2B platforms. There's zero Reddit discussion about the tool, which is unusual for a platform at this feature level. Solid on paper, minimal public track record.
Ampliz gives you 100 credits for $50. Exellius gives you 6,000 for $59. Prospeo gives you 98% email accuracy across 300M+ profiles refreshed every 7 days - at roughly $0.01 per verified email. No annual contracts, no sales calls.
Stop comparing niche tools. Start with data 15,000+ companies already trust.
Head-to-Head Feature Comparison
| Feature | Ampliz | Exellius | Winner |
|---|---|---|---|
| Database size | 400M+ contacts | 100M+ contacts | Ampliz |
| Email accuracy | Not specified | 95-98% | Exellius |
| Verification | Not detailed | SMTP + activity + human QA | Exellius |
| Enrichment | CRM enrichment/cleaning | Firmographics, technographics, intent signals | Exellius |
| CRM integrations | Salesforce, HubSpot | Salesforce, HubSpot & more | Tie |
| Compliance | GDPR | GDPR | Tie |
| Data refresh | Not specified | Real-time updates | Exellius |
| Unique niche | Healthcare + APAC | Amazon seller data | Depends on ICP |
Ampliz doesn't publish a specific email accuracy number - a red flag when you're paying per credit. Exellius does, but there's an inconsistency between the 98% on their homepage and the 95%+ in their FAQ. In our experience, when a vendor publishes two different accuracy numbers, the lower one is closer to what you'll see in production.
Ampliz wins on raw database size, but size without accuracy is noise. Exellius wins on feature breadth - technographics, intent signals, and that Amazon seller dataset are modules Ampliz simply doesn't match outside healthcare.
Pricing Breakdown
Ampliz pricing:
| Plan | Price | Credits |
|---|---|---|
| Free | $0 | 10 credits |
| Monthly | $50/mo | 100 credits |
| Yearly | $480/yr | 100 credits/mo |
| Healthcare | Custom | Quote-based |
Exellius pricing:
| Plan | Price | Credits |
|---|---|---|
| Free | $0 | 75 credits |
| Basic | $59/mo | 6,000 credits |
| Growth | $119/mo | 13,000 credits |
| Professional | $199/mo | 25,000 credits |
| Enterprise | Custom | Quote-based |
Look at those numbers. Ampliz gives you 100 credits for $50/mo. Exellius gives you 6,000 credits for $59/mo - roughly 60x more volume for $9 more per month, with unused credits rolling over for 3 months. Ampliz's free plan gives you 10 credits. Ten. That's not a trial, that's a tease.
If you're doing healthcare prospecting, Ampliz's custom plan might justify the premium. For everything else, the pricing gap is impossible to ignore.
Who Should Pick Which
Here's the thing: if your deal sizes are modest and you aren't selling into hospitals, neither of these tools is the obvious choice. Both have thin review footprints that make it hard to predict what you'll actually get at scale.
If you're building a sales prospecting motion, the bigger risk isn't "which tool has more contacts" - it's whether the data holds up once you start sending at volume.
Use Ampliz if you're selling into healthcare or your target accounts are concentrated in APAC or DACH markets. The vertical specialization justifies the cost.
Use Exellius for general B2B outbound at volume, Amazon seller prospecting data, or when you simply need more credits per dollar.
Skip both if you need a platform with hundreds of verified reviews and a data refresh cycle you can actually verify.
A Stronger Alternative to Both
We've seen teams switch from niche providers specifically because weekly data refreshes mean fewer bounces and cleaner sequences from day one. Prospeo covers 300M+ professional profiles with 143M+ verified emails at 98% accuracy, refreshed every 7 days - while the industry average sits around 6 weeks. You get 30+ search filters including buyer intent and technographics, plus native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Lemlist.
If you're comparing vendors primarily on enrichment depth, it's worth understanding what "enrichment" actually includes (and what it doesn't) in modern stacks - especially when you're stitching together multiple tools for data enrichment.
The free tier gives you 75 verified emails plus 100 Chrome extension credits monthly, which is enough to actually evaluate the data before committing. When you're weighing two niche providers and neither inspires confidence, a platform used by 15,000+ companies with transparent pricing is a safer bet.
If you're still deciding what category you actually need (database vs finder vs verifier), start with a broader shortlist of SDR tools and narrow from there.
Neither Ampliz nor Exellius publishes a verifiable data refresh cycle. Prospeo refreshes all 300M+ profiles every 7 days - 6x faster than the industry average. That's why teams see bounce rates under 4% and book 26% more meetings.
Fresh data means fewer bounces. Test 75 verified emails free - no credit card.
FAQ
Is Ampliz only for healthcare companies?
No - Ampliz offers a Global B2B plan starting at $50/mo with 100 credits. But its core strength is healthcare and APAC data. If you're outside those verticals, you're paying a premium for specialization you won't use.
Is Exellius a legitimate data provider?
Exellius holds a 4.9/5 rating on Datarade from 3 reviews and lists ratings across G2, Capterra, and Trustpilot, though review counts aren't publicly disclosed. It's a newer vendor with solid features on paper but a minimal public track record compared to established platforms.
What's the most accurate email finder for outbound?
Prospeo delivers 98% email accuracy across 143M+ verified emails with a 7-day data refresh cycle. Most B2B data providers refresh every 4-6 weeks, which means more bounces in your sequences. The free tier lets you test accuracy before committing.
Which tool offers better value per credit?
Exellius offers dramatically better credit volume - 6,000 credits at $59/mo versus Ampliz's 100 credits at $50/mo. For teams still evaluating data quality before scaling spend, Prospeo's free tier of 75 verified emails plus 100 Chrome extension credits monthly is the lowest-risk starting point.
