Dealroom vs Apollo.io: They Don't Actually Compete
Here's the thing - if you searched "Dealroom vs Apollo.io," there's a good chance you got results comparing Apollo to DealRoom, a Chicago-based M&A data room tool. Completely different company. We've seen this naming confusion trip up dozens of readers, so let's clear it up: Dealroom.co is an Amsterdam-based startup and VC intelligence platform. Apollo.io is a sales prospecting and outreach tool. Different buyers, different problems, different categories entirely.
30-Second Verdict
- Need startup/VC intelligence? Dealroom.co.
- Need sales prospecting and outreach? Apollo.io (but read the accuracy caveats below).
What Dealroom.co Actually Does
Dealroom.co is a global intelligence platform for tracking startups, funding rounds, and tech ecosystems. Its database covers 2M+ companies across 100M+ data points, with 336K VC rounds tracked globally and data on 120K+ investors. The data pipeline combines AI-powered harvesting with manual verification by an in-house intelligence unit, plus partnerships with 100+ government partners that unlock hard-to-find local data - especially across Europe. Dealroom also maintains a proprietary taxonomy covering 50+ sectors, which makes ecosystem benchmarking more granular than what you'd get from a general-purpose database.
In January 2026, Dealroom raised $7M to scale its US presence. That signals where the product is headed, but today it's still best known for European ecosystem coverage.
Use Dealroom.co if you're a VC/PE firm sourcing deals, a corporate innovation team benchmarking ecosystems, or a government agency measuring your local startup landscape. The G2 rating sits at 4.7/5 from 25 reviews, with reviewers praising data quality and ease of use - though several note that filters need work and advanced search is limited. There's also a recurring request for stronger integrations with professional networking platforms.
Skip Dealroom.co if you're an SDR building prospect lists or running cold email. It's not built for outbound workflows - no sequences, no dialer, no contact-level enrichment at scale.
Pricing is steep: EUR 12,500-17,000 per seat per year with a 3-seat minimum. That's EUR 37,500+ just to get started.
What Apollo.io Actually Does
Apollo.io is the tool most people actually mean when they're searching for B2B prospecting data. Its database is commonly cited at 210M+ contacts, and it bundles email sequences, a built-in dialer, and CRM integrations into one platform. For SDRs and AEs who need to find contacts and start outreach without stitching together five tools, it's the obvious starting point.
Apollo offers a free tier, with paid plans from $49-$119/user/month on annual billing. Its G2 rating is around 4.7/5 across 9,000+ reviews - massive social proof, and deserved for the breadth of features at that price.
But here's our hot take: Apollo is the best starter prospecting tool on the market. It isn't the best data tool. Those are very different things.
User critiques and third-party analyses commonly cite Apollo bounce rates in the 15-25% range, and in our experience, the credit system costs more than the sticker price suggests. Phone numbers cost 8x more credits than emails, credits expire each billing cycle, and overages run $0.20/credit. Real-world budgets for heavy outbound teams land closer to $150-$400/user/month once you factor in overages and add-ons. The consensus on r/sales threads tends to confirm this - Apollo's great for getting started, but teams doing serious volume often outgrow its data quality fast.
If your deal sizes are large enough to absorb a 20% bounce rate, Apollo works fine. If deliverability is your lifeblood, it's a problem.
Apollo's 15-25% bounce rates cost more than wasted credits - they torch your domain reputation. Prospeo delivers 98% email accuracy through a proprietary 5-step verification process, refreshed every 7 days. Teams switching from Apollo book 35% more meetings.
Stop paying Apollo prices for emails that bounce. Start free with 75 verified emails.
Side-by-Side Comparison
| Dealroom.co | Apollo.io | Winner | |
|---|---|---|---|
| Category | Startup/VC intelligence | Sales prospecting | Different categories |
| Database | 2M+ companies, 100M+ data points | 210M+ contacts | Apollo (for prospecting) |
| Pricing | EUR 12,500-17K/seat/year (3-seat min) | Free-$119/user/mo | Apollo (dramatically cheaper) |
| Best for | Investors, ecosystems | SDRs, outbound teams | Depends on your role |
| G2 Rating | 4.7/5 (25 reviews) | ~4.7/5 (9K+ reviews) | Apollo (volume of proof) |
| Data method | AI + manual + gov partners | Web crawling + user-contributed | Dealroom (for company data) |
| CRM integrations | Salesforce, HubSpot | Salesforce, HubSpot, more | Apollo (broader ecosystem) |
| Key limitation | Not an outreach platform | 15-25% bounce rates | - |
Our pick: If you're reading a Dealroom vs Apollo.io comparison, you almost certainly need Apollo's category, not Dealroom's. But Apollo's data quality gap is real - and that's where the next section matters.
B2B contact records decay roughly 30% per year. People change jobs, companies rebrand, phone numbers get reassigned. That stat matters far more for Apollo's use case than Dealroom's - if you're running outbound sequences, stale data means bounced emails and burned domain reputation. If you're actively managing email deliverability, that decay rate becomes a real cost center.
Which Tool Do You Actually Need?
Choose Dealroom.co if you're:
- A VC or PE firm evaluating startups and tracking funding rounds
- A corporate innovation team benchmarking tech ecosystems
- An ecosystem manager (government, accelerator) measuring local startup activity
- Focused primarily on European markets
Choose Apollo.io if you're:
- An SDR or AE building prospect lists and running cold email
- A startup that needs prospecting + outreach in one tool
- Looking for a free tier to get started before committing budget
Some teams genuinely need both. If you're in corporate development tracking startups via Dealroom and then doing outbound to founders, that's a real workflow - just recognize they're separate purchases solving separate problems and budget accordingly.
Dealroom's natural competitors are PitchBook (pricing commonly starts around $12,000/year and can run to $70,000+) and Crunchbase (Pro is $49/month on annual billing or $99/month monthly). Apollo's competitors are ZoomInfo, Cognism, and Lusha. If Apollo's accuracy concerns you, keep reading.
When Apollo's Data Isn't Enough
The platform delivers 143M+ verified emails and 125M+ verified mobiles on a 7-day refresh cycle - teams switching from Apollo report 35% more meetings booked. That 98% email accuracy comes from a proprietary 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering, none of it dependent on third-party email providers. Pricing runs roughly $0.01 per email with a free tier of 75 emails/month, no contracts, and no sales calls required. If you're comparing options, start with a shortlist of data enrichment services and a dedicated sales prospecting database.
If you're outgrowing Apollo's data quality but don't need Dealroom's VC intelligence, you need a prospecting tool built on accuracy. Prospeo gives you 143M+ verified emails and 125M+ verified mobiles at ~$0.01/email - no confusing credit tiers, no annual contracts, no sales calls.
Replace Apollo's guesswork with 98% verified data. No contracts required.
FAQ
Is Dealroom the same as DealRoom?
No. Dealroom.co tracks startups, funding rounds, and ecosystem data for investors - headquartered in Amsterdam. DealRoom is a Chicago-based M&A data room for secure document exchange during due diligence. Different companies, confusingly similar names.
Can I use Dealroom.co for sales prospecting?
Not effectively. Dealroom covers companies, funding rounds, and ecosystem intelligence, but it isn't built for outbound sales workflows. It lacks sequences, a dialer, and contact-level enrichment at scale. For prospecting, you need a dedicated tool like Apollo.io or Prospeo.
What's the most accurate Apollo.io alternative for email?
Prospeo delivers 98% email accuracy on a 7-day data refresh cycle, compared to Apollo's 15-25% bounce-rate range. The free tier includes 75 verified emails per month - enough to benchmark against your current stack before committing budget.
