DealRoom vs DiscoverOrg: Different Tools, Different Jobs
Your VP of Sales told you to "look into DiscoverOrg" because that's what they used at their last company in 2018. You Googled it, saw Dealroom.co listed next to DiscoverOrg in some directory, and ended up here. Here's the thing: they're not competitors, and one of them doesn't exist anymore.
These tools don't go head-to-head. The fact that you're comparing them means a directory or AI tool gave you bad information - sites like LeadSourceFinder lump Dealroom.co alongside ZoomInfo under "Sales Intelligence Platforms," which is exactly how this confusion starts.
30-Second Verdict
- Tracking startups, funding rounds, and investors? Dealroom.co. It's a VC/ecosystem intelligence platform, not a sales tool.
- Need what DiscoverOrg used to offer? DiscoverOrg is dead. It's ZoomInfo now, starting at ~$15,000/yr on annual contracts.
DiscoverOrg No Longer Exists
DiscoverOrg acquired Zoom Information, Inc. in February 2019. By September of that year, the brands had merged under "ZoomInfo Powered by DiscoverOrg," and the combined platform was serving 13,500+ clients with $350M in annual recurring revenue.
DiscoverOrg's legacy selling points - 95% data accuracy, 300 human researchers, contact verification every 90 days - all rolled into ZoomInfo's broader suite. ZoomInfo went public, hit $1.21B in revenue by 2024, and changed its ticker symbol from "ZI" to "GTM" in May 2025. If someone sends you to "DiscoverOrg" today, they mean ZoomInfo.
What Each Tool Actually Does
Dealroom.co
Dealroom.co is a startup and VC ecosystem intelligence platform covering 7 continents and 40+ countries with 100+ ecosystem partners. It tracks 3.2M companies, 225K investors, and 1.5M people. The core use cases are deal sourcing, ecosystem mapping, and funding analysis - not outbound sales. It's built for VCs, governments, and ecosystem builders. G2 rating: 4.7/5 with 25 reviews.
Pricing is public: Premium starts at EUR12,500/year (3 seats minimum), Premium Plus at EUR17,000/year. There's a 3-day free trial with 50 export credits, no credit card required.
ZoomInfo (Formerly DiscoverOrg)
ZoomInfo is an enterprise B2B sales intelligence platform covering 500M professional profiles, 174M verified emails, and 70M+ direct dials. It bundles intent data, technographics, org charts, and workflow automation into one platform. G2 rating: 4.5/5 with 9,036 reviews.
The most common complaint in reviews? Price. Professional plans start around $15,000/yr, Advanced runs $22,000-$28,000/yr, and Elite hits $35,000-$45,000+/yr. Many teams end up paying close to $50,000 annually once add-ons and seat expansions stack up. Data reliability also drops noticeably for smaller companies and non-US markets, which we've heard repeatedly from teams who've switched away.
G2 lists a 1-month implementation timeline, so don't expect a "set it up in an hour" experience.
DiscoverOrg doesn't exist anymore, and ZoomInfo wants $15K+ just to get started. If all you need is verified contact data for outbound, Prospeo delivers 300M+ profiles with 98% email accuracy and 125M+ verified mobiles - refreshed every 7 days, not every 6 weeks.
Skip the enterprise contracts. Get better data at $0.01 per lead.

Which One Do You Need?
You're sourcing startup deals, tracking funding, or benchmarking ecosystems. Dealroom.co is purpose-built for this. ZoomInfo won't help you map Series A deal flow or compare innovation corridors across Europe.
You're running enterprise outbound and have the budget for a full GTM platform. ZoomInfo is the incumbent. It's expensive and the contracts are rigid, but the database depth and workflow breadth are hard to match at scale. Just budget for the real number - $30K-$50K - not the sticker price.
You need verified B2B contact data without spending $15K+ or signing an annual contract. Neither tool is the right answer. In our experience, most teams searching this comparison actually just need accurate emails and direct dials, not a VC intelligence platform or a $50K enterprise suite.
Let's be honest: if your average deal size is under $25K, you almost certainly don't need ZoomInfo-level infrastructure. The ROI math falls apart when your data platform costs more than several closed deals.
B2B Contact Data Without the Enterprise Price Tag
For teams that just need to find and reach the right people, Prospeo covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers. Data refreshes every 7 days - compared to the 4-6 week industry average. There's a free tier (75 emails + 100 Chrome extension credits per month), paid plans run roughly $0.01 per lead, and there are no annual contracts. Sign up, search with 30+ filters, export verified contacts, and push them straight to your sequencer.
If you're building lists from scratch, it also helps to understand firmographic filters and how lead enrichment fits into your outbound workflow.
One of our customers, Snyk, cut their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180% after switching. That's the kind of difference fresh, verified data makes when you're running outbound at scale. (If you're troubleshooting deliverability, start with email bounce rate benchmarks and fixes.)
Snyk's 50 AEs cut their bounce rate from 35-40% to under 5% and grew AE-sourced pipeline 180% after switching to Prospeo. That's what happens when your data refreshes weekly instead of monthly and emails actually verify at 98%.
Stop paying DiscoverOrg-era prices for stale data.
