Nymeria vs ProsperFleet (Valgen): Different Tools, Different Jobs
You're comparing a fleet intelligence database against a general B2B contact enrichment tool. That's like comparing a forklift to a sedan. Nobody's published a head-to-head because they aren't really competitors.
The 30-second verdict: ProsperFleet tells you which companies have fleets, how many vehicles, what types, and where they're located. Nymeria finds email addresses and phone numbers for people at most companies. If you sell into the fleet vertical, you likely need both - fleet attributes to identify targets, then contact data to reach decision-makers.
What Each Tool Does
ProsperFleet (Valgen)
ProsperFleet is a vertical database for companies that sell to fleets. It covers light-duty commercial vehicles - contractor pickups, cargo vans, field sales fleets - that many fleet databases like RigDig don't focus on. You get location-level data with multiple contacts per fleet across maintenance, safety, procurement, and HR.
Valgen reviews company records via phone calls on a rotating basis at roughly 1 million calls per month, and it also runs monthly processes like email verification and job-change tracking. Many records get reviewed within 30-90 days, with most of the remainder reviewed within six months. ProsperFleet offers a 90% accuracy guarantee - if 10%+ of emails hard bounce, they replace records. It integrates with Salesforce and HubSpot. On G2, it sits at 4.0/5 across 3 reviews, with users praising light-duty coverage but noting limited filters.
Use this if you sell fleet parts, telematics, fuel cards, or maintenance services and need vehicle counts before you pick up the phone. Skip this if you're doing general B2B outreach and don't care about fleet attributes.
Nymeria
Nymeria takes a completely different approach. It's a general-purpose contact enrichment tool with over 811 million unique profiles, built around a browser extension workflow. Install it on Chrome, Edge, or Firefox, visit a professional or social profile, and pull emails, phone numbers, and social links in one click. A REST API handles bulk enrichment for dev teams.
Pricing is self-serve with monthly and annual options (annual saves 20%): Nano at $39/month, Micro at $79/month, Kilo at $159/month, plus Enterprise tiers with custom pricing. Free accounts get 5 credits every month with no credit card required. On G2, Nymeria scores 4.7/5 across 6 reviews. Users love the speed, though one reviewer noted it's "usually helpful 90% of the time."
Enrichment alternatives like FullEnrich often start around $29/mo, so Nymeria isn't the cheapest option here - but its API and browser extension combo is hard to beat at this price point.
Use this if you need lightweight, affordable enrichment with API access. Skip this if accuracy is mission-critical - G2 reviews mention occasional outdated contact info.
Fleet intelligence without verified contact data is a $25K gamble. Prospeo's 98% email accuracy and 125M+ verified mobile numbers turn fleet targets into booked meetings - with a 7-day refresh cycle that catches job changes 30-90 day databases miss entirely.
Stop burning your domain on stale fleet contacts.
Side-by-Side Comparison

| Data type | Fleet attributes + contacts | People/company contact enrichment |
| Database scope | U.S. trucking + business fleets (incl. light-duty/local) | 811M+ global profiles |
| Pricing | ~$5K-$25K+/yr (credit model, custom quotes) | $39-$159/mo (annual available) |
| Integrations | Salesforce, HubSpot | REST API + browser extensions |
| API | Not a core emphasis (exports + services are central) | REST API + bulk enrichment |
| Data freshness | Many records 30-90 days; remainder within 6 months | Credit-based enrichment + verification |
| G2 rating | 4.0/5 (3 reviews) | 4.7/5 (6 reviews) |
| Best for | Fleet vertical targeting | General contact lookup |
ProsperFleet's credit model charges 1 credit per company/HQ and 0.5 per location/branch, with free re-downloads within 12 months. Dollar pricing isn't public - expect custom quotes. Nymeria's plans are self-serve, so you can start without a sales call.
When to Choose Each Tool
Choose ProsperFleet
You sell into the fleet vertical and need data that general B2B platforms can't provide. FMCSA data shows roughly 686,000 active companies in the U.S. (as of September 2021), but 54% are single-vehicle owner-operators and only 2% have 50+ power units - about 12,600 fleets worth targeting at scale.
Generalist platforms miss badly here. We've seen teams waste months targeting "fleet companies" in Demandbase only to discover that as few as 6% of recommendations actually matched their target accounts. Employee count and revenue are terrible proxies for fleet size. Before buying any fleet data, check whether the provider covers your vehicle classes, geographic granularity, and contacts per company - not just fleet counts.
Choose Nymeria
You need a fast, affordable way to find contact information across industries. The browser extension is genuinely quick for one-off lookups, and the API handles bulk enrichment well. At $39/mo, it's accessible for solo SDRs and small teams who don't need fleet-specific intelligence.
The Stack That Actually Works
Here's the thing: identifying fleet companies and reaching their decision-makers are two separate problems. ProsperFleet tells you who has 50 trucks in Dallas. But you still need verified emails and direct dials for the VP of Fleet Operations.
In our experience, the winning workflow pairs fleet intelligence for targeting with a verified email finder and mobile data for outreach. Prospeo's 7-day refresh cycle catches job changes that 30-90 day databases miss entirely, and its 98% email accuracy means you're not torching your sender reputation on stale data. With 125M+ verified mobile numbers and a 30% pickup rate, you can actually get fleet decision-makers on the phone - not just in their inbox. The free tier (75 emails/month) lets you test the workflow before committing.
Let's be honest: most teams selling into fleets overspend on data and underspend on verification. A $25K fleet database feeding unverified emails into your cold email sequences will burn your domain faster than no data at all.
ProsperFleet tells you who runs 50 trucks in Dallas. Prospeo tells you the VP of Fleet Ops' verified email and direct dial - at $0.01 per lead. Teams using Prospeo book 26% more meetings than ZoomInfo and 35% more than Apollo.
Pair fleet targeting with data that actually connects you to buyers.
FAQ
Are Nymeria and ProsperFleet competitors?
No. ProsperFleet is a fleet vertical database covering vehicle counts and location-level fleet data, including DOT/FMCSA-linked identifiers where applicable. Nymeria is a general B2B contact enrichment tool. They serve entirely different needs and work best as complementary layers in a fleet outbound stack.
Does ProsperFleet publish pricing?
ProsperFleet uses a credit model (1 credit per company, 0.5 per location) but doesn't disclose dollar pricing publicly. Expect custom quotes in the $5K-$25K+/year range. Request a trial and a 50-record sample before committing.
What's the best approach for verified contact data in the fleet vertical?
Pair a fleet database like ProsperFleet for targeting with a verification-first enrichment platform for outreach. Prospeo covers 300M+ profiles with 98% email accuracy on a 7-day refresh cycle, plus 125M+ verified mobiles - a strong complement to any fleet intelligence source. The r/sales community regularly recommends separating your data sourcing from your verification layer for exactly this reason.
