Revli vs Tomba: They're Not Really Competitors
Your manager handed you a list of 500 prospects and told you to "find the right tool." You're comparing Revli vs Tomba, but here's the thing - one of these tools doesn't even do email finding. They're different product categories that get lumped together because they both touch B2B contact data. We've tested both, so let's sort this out fast.
30-Second Verdict
Revli is a funded startup database. Tomba is an email finder. Comparing them is like comparing a CRM to a dialer.
What Is Revli?
Revli delivers weekly-updated databases of recently funded startups and active investors, bundled with verified decision-maker contacts - emails, mobile numbers, and profiles. Think of it as a niche intelligence layer rather than a general-purpose prospecting tool. You get filters for industry, location, funding stage, and hiring signals, plus CSV export on most plans.
Use it if you're an agency or growth team that specifically targets venture-backed companies. The weekly refresh means you're working with fresh funding data, not stale Crunchbase exports. But if your ICP extends beyond recently funded startups and active investors, Revli won't help you - it's built for that niche, not broad mid-market or enterprise coverage.
Pricing: monthly and annual billing (annual saves 30%), with a 7-day free trial that doesn't require a credit card. For sales teams and agencies, plans range from $69/mo to $199/mo depending on billing cycle. For founders raising capital, the Investor plan runs $55/mo annual or $79/mo monthly.
What Is Tomba.io?
Here's where Tomba gets interesting - and where it falls short.
In Tomba's February 2026 benchmark, it scored 80.3% accuracy across 5,000 searches. That means roughly 1 in 5 lookups won't return a valid email. For a tool claiming 450M+ emails across 76M domains, that hit rate is underwhelming. On G2, Tomba holds a 4.7/5 rating from 25 reviews, with users praising the clean UI and data quality when results do come back. The main gripes: quota limits feel tight on lower plans, there are UI inconsistencies between sections, and Tomba can't find Gmail addresses even when they're publicly listed on a website. The API is surprisingly deep - author finding, phone finding, technology detection, and email source traceability - but the core accuracy gap is hard to ignore when you're running real campaigns.
Pricing starts free with 25 searches and 50 verifications, then scales to $441/year on the Basic plan (roughly $37/mo billed annually) up through $4,041/year for Pro Plus. One detail worth knowing: a single domain search costs 1 credit per 10 emails returned, so high-volume lookups burn through quotas faster than you'd expect.
Revli covers funded startups. Tomba finds emails at 80.3% accuracy. Prospeo gives you 300M+ profiles with funding filters, 98% email accuracy, and 125M+ verified mobiles - no stitching tools together.
Replace two tools with one platform that actually scales.
Side-by-Side Comparison
Putting these two tools in the same table almost feels unfair since they solve different problems. Adding a third column makes the picture clearer.
| Revli | Tomba | Prospeo | |
|---|---|---|---|
| Primary function | Funded startup + investor DB | Email finder/verifier | Full B2B data platform |
| Database size | Recently funded startups + active investors | 450M+ emails, 76M domains | 300M+ profiles, 143M+ emails |
| Email accuracy | N/A (curated lists) | 80.3% (vendor benchmark) | 98% |
| Verified mobiles | Included for contacts in DB | Available via Phone Finder | 125M+ |
| Data refresh | Weekly | Not disclosed | 7 days |
| Free tier | 7-day trial | 25 searches / 50 verifs | 75 emails + 100 credits/mo |
| Entry paid price | From $55/mo (annual) | ~$37/mo (annual) | Credit-based from ~$0.01/email |
| Best for | Teams targeting funded startups | Email lookup by domain | B2B prospecting at scale |
When to Use Which
Use Revli when your entire pipeline depends on recently funded companies. If you're an agency selling to Series A-C startups, or a founder looking for active investor contacts, Revli's niche focus is genuinely valuable. No general-purpose database curates this data with weekly freshness.
Use Tomba when you've already got a target company list and need email addresses. It's a solid lightweight finder with good API coverage, especially if you're aligned with its plan quotas and comfortable with the 80.3% accuracy rate. The Growth plan includes 5,000 searches and 5,000 verifications when billed annually, which is decent for small teams.
Use both together when you pull funded startup lists from Revli but need additional contacts beyond what Revli provides. If you're pairing Revli with an email finder, accuracy matters a lot. In our experience, the gap between 80% and 98% accuracy shows up fast at scale - it's the difference between healthy domain reputation and deliverability problems that take weeks to fix.
If Neither Fits
Look, most teams weighing Revli vs Tomba don't actually need either. They need a platform that does both jobs well.
Prospeo covers email finding with 98% accuracy, and its 30+ search filters include funding signals and technographics - covering some of Revli's territory across a 300M+ profile database. You also get 125M+ verified mobiles with a 30% pickup rate, a 7-day data refresh cycle, and native integrations with Salesforce, HubSpot, Smartlead, Instantly, and Lemlist. Self-serve, no contracts. We've seen teams like Stack Optimize build to $1M ARR while keeping client deliverability above 94% and bounce rates under 3% - that kind of reliability just isn't possible when you're starting from 80% accuracy on the email-finding side.
Stack Optimize built to $1M ARR with sub-3% bounce rates using Prospeo. That's what happens when your email accuracy starts at 98% instead of 80%. Funding signals, verified mobiles, 7-day data refresh - all self-serve at $0.01/email.
Stop losing 1 in 5 emails to bad data.
FAQ
Is this even a fair comparison?
Not really - they're different product categories. Revli gives you curated lists of recently funded startups and active investors with verified contacts. Tomba finds email addresses for prospects you already know about. You'd use Revli to build a target list, then an email finder to expand contacts beyond what Revli provides.
Is Tomba's 80.3% accuracy good enough for outbound?
At 1,000 emails, roughly 197 will be missing or invalid. For low-volume, targeted outreach, that's workable. For high-volume campaigns where domain reputation is critical, you need 98%+ accuracy. Email lists decay by nearly 28% annually, so starting higher gives you more runway before your data goes stale.
Does Revli work for companies that aren't recently funded?
No. Revli's database covers recently funded startups and active investors exclusively. If your ICP includes established companies or bootstrapped businesses, you need a general B2B database with broader coverage and filters beyond just funding stage.
