ContactOut vs Winmo: You're Probably Comparing the Wrong Tools
Your VP dropped both names in the same Slack thread and asked you to "evaluate them." You pulled up both sites and realized within 30 seconds: these tools have almost nothing in common. That instinct is correct - and if you're weighing ContactOut vs Winmo, it should change how you approach this decision entirely.
The 30-Second Verdict
Winmo is ad sales intelligence. It tracks $100B+ in media spend, maps brand-agency relationships, and flags timing signals like upcoming agency reviews. If you sell ad space, sponsorships, or media services, it's purpose-built for you. Expect to pay $12,000+/year.
ContactOut is a contact finder. It pulls emails and phone numbers while you browse professional profiles and other web sources via a Chrome extension. It's built for recruiters and B2B reps who need direct contact info fast. Paid plans run $99-$199/mo, with Team/API pricing sold separately.
What Each Tool Actually Does
What Is Winmo?
Winmo is a sales intelligence platform for the advertising and media industry. Its database tracks 230K+ hand-verified decision-makers, 26K+ brand-agency relationships, and over $100B in media spend. That's a narrow slice of the B2B world, but within that slice, nothing else comes close.
The real differentiator is WinmoEdge - a predictive engine that flags upcoming opportunities like agency reviews, budget shifts, and new product launches 3-18 months in advance with 80%+ prediction accuracy. For ad sales teams, that kind of lead time is the difference between showing up first and showing up late. Winmo also includes Compose, an AI outreach assistant that claims a 233% response rate boost, and it integrates partner data from Adbeat, iSpot.tv, and Bombora for deeper media intelligence.
What Is ContactOut?
ContactOut is an email and phone number finder, primarily used through a Chrome extension. It provides access to 350M professional profiles with verified contact data.
There's a free tier that includes 40 emails and 3 phone numbers, which makes it easy to test but hard to scale. It's built for recruiters and individual prospectors who need quick contact info while browsing - not for teams running high-volume outbound.
Side-by-Side Comparison
| Winmo | ContactOut | |
|---|---|---|
| Database | 230K+ hand-verified decision-makers | 350M profiles |
| Pricing | ~$12K-$65K/yr | Free-$199/mo |
| Data refresh | 60-day full cycle (daily refresh work) | Hourly-updated via API |
| G2 rating | 4.4/5 (423 reviews) | 4.4/5 (109 reviews) |
| Integrations | Salesforce, HubSpot, Microsoft Dynamics | Salesforce, HubSpot, Lever, Greenhouse, Bullhorn + Zapier |
| Chrome extension | No | Yes |
| Best for | Ad sales & media | Recruiters & individual prospectors |
Winmo is deep but narrow. ContactOut is broad but credit-limited. If neither profile fits your team, a general-purpose platform with wider coverage and self-serve pricing is the more practical choice for most B2B outbound.
Winmo locks you into a $12K+ contract for ad sales data. ContactOut meters every lookup. Prospeo gives you 300M+ profiles, 98% verified emails, and 125M+ mobile numbers - starting free at 75 emails/month with no sales calls required.

Pricing Breakdown
Winmo doesn't publish pricing. Based on Vendr procurement data and a FullEnrich analysis of 40+ contracts, here's what teams actually pay:
- Core: $13,995+/yr (3 users, research requests $150-$300 each)
- Standard: ~$18K-$22K/yr (5 users, 8 research requests included, WinmoEdge alerts included)
- Explorer: $25K-$40K+/yr (10 users, 20 research requests, premium integrations/partner data)
- Enterprise: $40K-$65K/yr (unlimited research requests + dedicated support)
Add-ons like intent data or media insights can push total cost past $50K. That's serious budget for a tool that only covers the ad/media vertical.
ContactOut is simpler. The free plan includes 40 emails and 3 phone numbers - enough to test, not enough to prospect. The Email plan runs $99/mo, and Email+Phone is $199/mo. Credit limits are the main friction point users flag on G2.
Data Quality and Freshness
Here's the thing: most teams agonizing over this comparison don't sell ad space and don't need a credit-metered email finder. They need reliable contact data at scale. But if you do fall into one of these camps, here's how the data stacks up.
Winmo's data shines when you're targeting enterprise advertisers and agencies. The entire database is verified on a 60-day cycle with daily refresh work in between. If Winmo doesn't track an advertiser or agency, you can submit a research request and get the info within 48 hours. Winmo also highlights 98% email deliverability. For ad sales, this is gold - G2 reviews frequently call out timely prospecting intel and change tracking as top strengths.
Winmo's data falls short when you're targeting SMBs. Coverage skews heavily toward large brands with massive spend. One G2 reviewer noted they found only about 10% of the smaller companies they searched for.
ContactOut's data works well when you need quick email lookups while browsing professional profiles. API users get hourly-updated contact data, which is genuinely fast.
ContactOut's data frustrates when you need volume. The credit system means you're constantly watching a meter, and the free tier runs dry in a single prospecting session.
Who Should Use Which
Let's be honest - most people reading this comparison don't actually need either tool. We've evaluated both platforms extensively, and here's how we'd break it down:
You sell ad space, sponsorships, or media services. Go with Winmo. Nothing else maps brand-agency relationships and predicts agency reviews like it does. The $12K+ price tag pays for itself if you close one deal from a WinmoEdge alert. G2 data shows ROI at around 13 months.
You're a recruiter or individual rep who needs emails while browsing. ContactOut is solid. The Chrome extension is fast and the free tier lets you test without commitment. Just know you'll hit credit walls quickly if you try to scale.
Most teams comparing ContactOut vs Winmo actually need general B2B outbound data - not an ad-sales database or a credit-gated extension. Prospeo delivers verified emails at $0.01 each, refreshed every 7 days, with 30+ filters including buyer intent and technographics.
Enterprise-grade data without enterprise pricing or annual contracts.
FAQ
Is Winmo worth $12K+ per year?
Yes - if you sell ad space or media services to enterprise brands. WinmoEdge's predictive alerts (80%+ accuracy, 3-18 months ahead) justify the cost when a single closed deal covers the annual fee. If you don't sell to advertisers, it's an expensive mismatch.
Does ContactOut work outside professional profiles?
Its core value is the Chrome extension for finding emails while you browse. There's also a Search Portal for broader prospect searches. The 40 free emails and 3 phone numbers on the free tier restrict heavy usage significantly, though - the consensus on r/sales threads is that you'll outgrow the free plan within a week.
What's a good alternative for general B2B prospecting?
Neither ContactOut nor Winmo fits general outbound well. ContactOut is credit-limited and Winmo is ad-sales-focused. For teams running standard B2B outbound, a platform with broad coverage, verified data, and no per-credit anxiety is the better fit. Prospeo covers 300M+ profiles with 143M+ verified emails and 125M+ verified mobiles on a 7-day data refresh - all self-serve starting at 75 free emails/month.
