Tomba vs ProsperFleet (Valgen): Two Different Tools for Two Different Problems
Comparing Tomba vs ProsperFleet (Valgen) is like comparing a hammer to a forklift. One finds email addresses. The other helps you target commercial fleets.
Here's the thing: this isn't a fair fight, because it isn't the same category.
What Each Tool Does
Tomba - Email Finder
Tomba is a general email finder built around domain search. Drop in a company domain, pull associated email addresses. You also get browser extensions, an API for bulk workflows, and built-in verification.
Pricing ranges from free (25 searches/month and 50 verifications/month) up to $5,388/year on Pro Plus. It's straightforward self-serve access with no sales calls required.
ProsperFleet (Valgen) - Fleet-First Database
ProsperFleet is a fleet intelligence platform for selling into trucking, logistics, and commercial vehicle operators. The numbers are niche-specific: 30M commercial vehicles, 1.2M U.S. companies running 5+ vehicles, 1.6M fleet locations, and 2.2M contacts tied to fleet-specific roles.
It's not "no-email" - ProsperFleet includes contact emails and profile URLs for those fleet-role contacts. HubSpot, Salesforce integration ships with every plan at no extra cost. Among fleet-data competitors like RigDig and FleetSeek, ProsperFleet stands out for its light-duty coverage, which is a gap most fleet databases ignore entirely.
Side-by-Side Comparison
| Feature | Tomba | ProsperFleet (Valgen) | Prospeo |
|---|---|---|---|
| Best for | Quick domain email lookups | Fleet targeting + fleet-role contacts | Verified B2B contact data at scale |
| Database size | N/A (email finder workflows) | 30M vehicles | 300M+ profiles |
| Fleet/vehicle data | No | Yes | No |
| Email accuracy | Includes email verification | 90% accuracy guarantee | 98% verified |
| Data refresh | N/A | 30-90 day review cycle | 7-day refresh |
| Pricing | Free + paid tiers (annual) | Credits (1/company, 0.5/branch) | ~$0.01/email |
| Free tier | 25 searches/mo | Trial on request | 75 emails/mo |
| Integrations | API, browser extensions, Google Sheets, Excel | HubSpot, Salesforce | Salesforce, HubSpot, Smartlead, Instantly, Lemlist, Clay |
| Contracts | Self-serve plans | Sales-led | No contracts |
ProsperFleet's "30M vehicles" is the point - you're buying segmentation that general databases don't even attempt. Prospeo's 300M+ profiles include 143M+ verified emails and 125M+ verified mobile numbers, which is a completely different scale for general B2B outreach.
How to Evaluate Fleet Data Before You Buy
Ask Valgen for segment-fit counts: how many fleets match your ICP by fleet size, duty type, geography, and cargo? Then validate with a 50-record sample before committing credits. If your wins cluster in one segment, don't pay for broad coverage you won't use.
Fleet databases won't help you reach general B2B buyers. Domain-lookup tools won't scale without wrecking your sender reputation. Prospeo gives you 300M+ profiles with 98% email accuracy on a 7-day refresh cycle - at roughly $0.01 per email.
Stop forcing niche tools into a general prospecting workflow.
Which Should You Choose?
Choose ProsperFleet If You Sell to Fleets
Use ProsperFleet when fleet attributes drive your targeting - vehicle counts, duty type, cargo carried, fleet locations - because that's what turns a generic list into an actual territory plan. No general email finder gives you this kind of segmentation.
ProsperFleet carries a 4.0/5 rating on G2 (3 reviews). Reviewers highlight light-duty fleet coverage as a differentiator, though one notes the filters can feel limited for highly specific queries.
Skip this if you're selling SaaS, marketing services, or anything outside the fleet ecosystem. You'd be paying for data you'll never touch.
Choose Tomba for Quick Email Lookups
Tomba works for lightweight domain-based lookups when you're not building a large, deliverability-sensitive list. We've seen this pattern too many times: someone scales a "found emails" tool to thousands of sends without verifying, and their domain reputation tanks within weeks. Keep domain-lookup tools in the small-batch lane, and you'll be fine.
The Practical Third Option
Look - if you're not selling into fleets, you don't need fleet intelligence at all. You need clean, fresh contact data you can trust at volume.
Let's be honest: for general B2B prospecting, the choice between a niche fleet database and a domain-lookup tool is a false binary. Most people reading this comparison need neither. They need a platform that handles prospecting end-to-end with data that's actually current.
Tomba caps free users at 25 searches. ProsperFleet requires a sales call just to trial. Prospeo ships 75 verified emails per month free - no credit card, no contract - backed by 143M+ verified emails and 125M+ mobile numbers.
Get broader coverage and better accuracy without a single sales call.
FAQ
Can ProsperFleet replace a general email finder?
No. ProsperFleet is built for fleet targeting and fleet-role contacts only. It covers 2.2M contacts in that niche, but it won't help you reach marketing directors at SaaS companies or anyone outside the fleet ecosystem.
Does Tomba include fleet or vehicle data?
Not at all. Tomba is strictly an email finder. Zero vehicle counts, no fleet size filters, no duty type segmentation, no fleet-location intelligence - none of the attributes that make ProsperFleet useful for fleet sellers.
What does ProsperFleet actually cost?
Pricing is quote-based and credit-driven: 1 credit per company/HQ record, 0.5 credits per branch location, and re-downloads within 12 months don't consume credits. Annual spend typically lands in the $5K-$25K range depending on volume and segment breadth.
What's a good alternative if I don't sell to fleets?
Prospeo offers 75 free emails per month with 98% accuracy and a 7-day data refresh cycle. For general B2B prospecting outside the fleet vertical, it delivers broader coverage at roughly $0.01 per email - no contracts, no sales calls required.
