Adapt.io vs Winmo: They're Not Really Competitors
Adapt.io costs $49/mo. Winmo starts at $13,995/yr. That price gap tells you everything about this comparison: these are two tools built for completely different jobs.
Adapt.io is a general-purpose B2B contact database with 250M+ contacts across every industry. Winmo is a niche ad-sales intelligence platform that tracks brand-agency relationships and predicts agency reviews 3-18 months before they happen. People land on this comparison when they need contacts for ad sales outreach, but one tool is database-first and the other is intelligence-first. Pick the wrong one and you waste either money or time.
Here's the thing: if you're not selling media, sponsorships, or ad tech, Winmo's $14K+ entry price buys you a Rolodex you'll never use. And if you are selling to advertisers, Adapt.io's broad database won't tell you which brands are about to switch agencies. Most teams need neither - they need accurate contact data without the baggage.
30-Second Verdict
| Adapt.io | Winmo | |
|---|---|---|
| Best for | Budget B2B prospecting | Ad sales intelligence |
| Starting price | Free / $49/mo | $13,995+/yr |
| Database size | 250M+ contacts | ~230K curated contacts |
| G2 rating | 4.6/5 (2,789 reviews) | 4.4/5 (423 reviews) |
| Key strength | Affordable, broad data | Agency-review predictions |
Skip both if you just need verified contact data without five-figure annual contracts. Prospeo starts free with 98% email accuracy, 143M+ verified emails, 125M+ verified mobile numbers, and a 7-day refresh cycle - all on transparent, self-serve credits where you pay only for valid addresses.
Feature-by-Feature Comparison
| Feature | Adapt.io | Winmo |
|---|---|---|
| Database size | 250M+ contacts | ~230K hand-verified contacts |
| Verification/refresh cycle | 5M+ data points refreshed daily | 60-day verification cycle |
| Email accuracy | Estimated 85-90% | N/A - not an email tool |
| Free plan | Yes (25 email credits + 25 enrichment credits; 25 contacts/day) | No |
| Contract terms | Monthly or annual | Annual only |
| Chrome extension | Yes | No |
| CRM integrations | Salesforce, HubSpot, etc. | Limited |
| Unique capability | Broad B2B data at scale | WinmoEdge predictions (80-81% accuracy) |
The numbers tell the story. Adapt.io is a volume play - 250M+ contacts across every industry. Winmo is a depth play - roughly 230K contacts in the advertising and media world, enriched with ad spend data, brand-agency mapping, and predictive alerts. If you're not selling to advertisers, Winmo's database is irrelevant.
Adapt.io: Quick Review
Adapt.io is a credit-based B2B contact database headquartered in Coimbatore, India. It serves sales teams that need affordable access to a large contact pool across industries, company sizes, and geographies. The Chrome extension is a standout for workflow speed, and G2 reviewers frequently praise ease of use (71 mentions).
Key limitations: contacts/day limits persist on self-serve plans (50/day on Starter and 100/day on Basic), phone numbers are locked behind the Basic tier ($99/mo), and email accuracy sits around 85-90% based on user reports. The free plan gives you 25 email credits per day plus 25 enrichment credits to test the waters, and there's a 7-day free trial with no credit card required. At $49/mo, it's one of the cheapest ways into B2B prospecting - but you get what you pay for.
G2 sentiment: 4.6/5 across 2,789 reviews. ROI timeline averages 16 months. One detail we noticed: 1,452 of 2,789 reviewers are Asia-based (about 52%), so if your ICP is North American, take accuracy praise with a grain of salt.
Winmo: Quick Review
Winmo is an ad-sales intelligence platform built for media companies, publishers, and agencies selling advertising. Its database of ~230K contacts is small by B2B standards, but each record is hand-verified and enriched with ad spend data, brand-agency relationships, and decision-maker context that no general-purpose database offers.
The real product is WinmoEdge, a predictive engine that analyzes 17 variables to flag opportunities 3-18 months ahead. It tracks prediction categories like predicted agency reviews (brands likely to switch agencies), marketers on the move (leadership job changes), new funding rounds, imminent campaigns and product launches, struggling companies, new markets and audiences, and shifts in ad spending. WinmoEdge is marketed at 80-81% prediction accuracy for those 3-18 month forecasts, which is genuinely valuable if your revenue depends on timing agency reviews. Winmo lists customers like Disney, NFL, and TikTok on its site.
G2 sentiment: 4.4/5 across 423 reviews. ROI timeline averages 13 months. Reviewers are overwhelmingly North American (413 of 423), and over 50% work in marketing and advertising. Implementation takes about 1 month.
Adapt.io caps you at 50-100 contacts/day. Winmo locks you into $14K+ annual contracts for 230K niche contacts. Prospeo gives you 143M+ verified emails and 125M+ mobile numbers with 98% accuracy - no daily limits, no annual lock-in, starting at $0.01/email.
Stop choosing between cheap-and-inaccurate or expensive-and-niche.
Pricing Breakdown (2026)
These pricing structures aren't in the same universe.
Pricing and review counts last checked: March 2026.
Adapt.io - credit-based, not per-seat:
| Plan | Price | Email Credits | Enrichment Credits | Contacts/Day |
|---|---|---|---|---|
| Free | $0/mo | 25/day | 25/day | 25 |
| Starter | $49/mo ($490/yr) | 500 | 500 | 50 |
| Basic | $99/mo ($990/yr) | 1,000 | 1,000 | 100 |
| Custom | Talk to sales | Custom | Custom | No daily limit |
A few constraints worth knowing: CSV export requires Starter or above. CRM export (Salesforce, HubSpot, Pipedrive, Zoho, Outreach, Salesgear) is locked to Basic+. Phone numbers only unlock on Basic ($99/mo) and above, so the Starter plan is effectively email-only. API access is Custom-only. There's a 7-day free trial with no credit card required - a low-risk way to test data quality for your specific ICP before committing.
Winmo:
| Plan | Estimated Price | Users |
|---|---|---|
| Core | $13,995+/yr | 3 users max |
| Standard | $18,000-$22,000/yr | 5 users |
| Explorer | $25,000-$40,000+/yr | 10 users |
| Enterprise | $40,000-$65,000+/yr | Unlimited |
Winmo's entry-level plan costs more than a full year of Adapt.io's top self-serve tier. Add-ons can push costs up fast: Intent Data runs $15,000-$25,000 and Media Insights adds $8,000-$12,000, putting a fully loaded Enterprise contract past $80K/yr. We've seen Winmo quotes vary widely once add-ons and extra seats are included - Vendr data shows a median of $12,000/yr across negotiated deals (range $8,673-$31,814), but that's still over 12x what Adapt.io Starter costs annually.
At $13,995+/yr, Winmo is priced like a revenue intelligence platform, not a contact database. That pricing only makes sense if WinmoEdge predictions directly drive your pipeline.
What Users Actually Say
Adapt.io - 4.6/5 on G2 across 2,789 reviews
Adapt.io's strongest praise centers on ease of use and its affordable entry point. Users consistently call out the interface as intuitive and the contact volume as impressive for the price. The flip side: credit limits frustrate power users (34 mentions), and some email addresses are flat-out wrong (14 mentions). On Reddit, some users mention struggling to convert Adapt.io contacts into booked meetings, which tracks with the estimated 85-90% email accuracy - roughly 1 in 10 emails bouncing compounds fast at scale.
Winmo - 4.4/5 on G2 (423 reviews), 4.5/5 on Capterra (131 reviews)
For ad sales teams, WinmoEdge alerts are genuinely valuable - multiple reviewers describe them as a breakthrough for spotting agency reviews before competitors do. Brand-agency mapping is unmatched, and implementation is fast (1 month average). The complaints center on price and data freshness. One Capterra reviewer wrote: "It is very pricey, and now that they've bought up their rivals, there is no real competition." Another described downloading a contact only to find the person had already left the company - a known issue with the 60-day verification cycle. A TrustRadius reviewer put it bluntly: "We have not seen a financial return on investment."
The geographic split is stark: 413 of Winmo's 423 G2 reviewers are in North America, and over 50% work in marketing and advertising. This tool serves one niche extremely well. Everyone else is overpaying.
Which One Should You Pick?
You sell to advertisers or agencies: Winmo. WinmoEdge predictions are unmatched for spotting agency reviews and ad spend shifts before they happen. If ad intelligence drives your revenue, the $14K+ price tag can pay for itself with one closed deal. No other tool replicates the brand-agency mapping and predictive alerts.
You need general B2B contact data on a budget: Adapt.io works at the entry level. The Chrome extension is solid, the free plan lets you test before buying, and $49/mo is hard to beat on price alone. But contacts/day limits (25-100/day) and 85-90% email accuracy become real bottlenecks once you're running outbound at any scale. It's a fine starting point, not a long-term solution.
You need accurate contact data without the compromises: Prospeo covers 300M+ profiles with 98% email accuracy, 143M+ verified emails, and 125M+ verified mobile numbers with a 30% pickup rate. The 7-day refresh cycle means weekly data freshness - in our experience, that cadence reduces bounce-driven deliverability issues fast. It starts free at 75 emails/month, scales to about $0.01 per verified email on paid plans, and doesn't lock you into annual contracts.
You need both ad intelligence AND contact data: Pair Winmo (or MediaRadar, its closest competitor with an average contract around $37K/yr) with a dedicated contact data platform. Winmo gives you the intelligence layer; a separate tool gives you verified emails and direct dials to actually reach those contacts.
If you want a broader shortlist first, start with our breakdown of sales intelligence tools and then narrow down to the best-fit B2B lead list tools.
Both tools refresh data on weeks-long cycles - Adapt.io daily but with 85-90% accuracy, Winmo every 60 days. Prospeo refreshes all 300M+ profiles every 7 days with 5-step verification, so you never email a dead address or dial a disconnected number.
Get contact data that's actually current - refreshed weekly, verified at 98%.
FAQ
Is Winmo worth the price for small teams?
Only if your revenue comes directly from selling to advertisers or agencies and you'll actively use WinmoEdge predictions. For teams under 10 reps, the $13,995+ minimum is hard to justify on contact data alone - you're paying for ad intelligence, not a general-purpose database. The 13-month average ROI timeline means you need patience and deal sizes large enough to recoup the investment within a few closed accounts.
Does Adapt.io have accurate email data?
Adapt.io claims real-time email verification, but G2 reviewers flag incorrect addresses as a recurring issue (14 mentions across 2,789 reviews). Accuracy sits around 85-90%, meaning roughly 1 in 10 emails bounces. That's workable for light prospecting but problematic at scale - especially since phone numbers require the $99/mo Basic plan, leaving cheaper-tier users with no fallback channel when an email doesn't land.
Can I use Adapt.io and Winmo together?
You can, but there's almost no overlap in what they do. Winmo identifies which brands and agencies to target and when to reach out. Adapt.io provides the emails and phone numbers to execute outreach. If you're in ad sales and have the budget, pairing Winmo's intelligence with a high-accuracy contact tool that offers weekly data refreshes is the strongest play.
What's a good alternative if neither tool fits?
Let's be honest - most teams comparing these two don't actually need either. If your goal is reliable B2B contact data without five-figure commitments or daily caps, look for a platform with 95%+ email accuracy, a fast data refresh cycle, and self-serve pricing. We built Prospeo around exactly those requirements: 300M+ profiles, 98% email accuracy, 7-day refresh, and a free tier at 75 emails/month with no credit card required.
