SalesQL vs ProsperFleet: Different Tools for Different Problems
Comparing SalesQL to ProsperFleet (Valgen) is like comparing a Swiss Army knife to a torque wrench. One pulls general B2B contact data from professional profiles. The other tells you which companies operate commercial fleets - five or more vehicles - in a specific geography. Pick the wrong one and you'll waste months chasing prospects who'll never buy. Valgen's own analysis found that only 15-20% of prospects identified through standard firmographic filters actually fit fleet buyer profiles.
30-second verdict:
- ProsperFleet if you sell to fleets and need vehicle-count data, duty-class segmentation, and fleet-specific job titles.
- SalesQL if you need cheap B2B contact data pulled from professional profiles and don't care about fleet intelligence.
Why This Comparison Is Misleading
SalesQL and ProsperFleet don't compete. SalesQL is a general-purpose contact enrichment tool. ProsperFleet is a vertical database built exclusively for the U.S. fleet and trucking market. Revenue and employee count are poor proxies for fleet size - there's no reliable relationship between the two.
Here's the thing: about 90% of companies with vehicles have only one or two, and roughly 1% of companies with 5+ vehicles even have a dedicated fleet job title. If you're filtering by "fleet manager" in a general B2B database, you're missing virtually everyone. We've seen fleet sellers waste entire quarters using horizontal tools before discovering vertical databases exist.
Side-by-Side Comparison
| SalesQL | ProsperFleet | Winner | |
|---|---|---|---|
| Focus | General B2B contacts | U.S. fleet/trucking data | ProsperFleet (fleet); SalesQL (general) |
| Data type | Emails & phones | Fleet size, vehicle types, contacts | ProsperFleet for depth |
| Coverage | Not disclosed | 1.2M companies (5+ vehicles), 1.6M locations, 30M vehicles, 2.2M contacts | ProsperFleet |
| Pricing | Free-$119/mo | ~$5K-$25K+/year (annual contract) | SalesQL for budget |
| Integrations | Chrome extension | Salesforce (paid add-on), HubSpot | SalesQL (no extra cost) |
| G2 rating | 4.5/5 (166 reviews) | 4.0/5 (3 reviews) | SalesQL (more data) |
| Best for | Budget contact enrichment | Fleet suppliers, OEMs, telematics | Depends on vertical |
If you sell to fleets, no amount of SalesQL credits will replace ProsperFleet's vehicle data. But if you don't sell to fleets, ProsperFleet is a multi-thousand-dollar paperweight. The real question for most teams isn't which of these to pick - it's whether they need either one at all.
SalesQL reviewers say you need a separate verifier before trusting their emails. Prospeo's 5-step verification is built in - 98% email accuracy, 143M+ verified emails, 125M+ verified mobiles, all refreshed every 7 days. No extra verification step eating into your savings.
Skip the verification workaround. Start with data that's already accurate.
The Tools Up Close
SalesQL
Use it if you need a cheap, fast way to pull emails and phone numbers from professional profiles. Pricing runs Free (50 credits/month), Basic ($39/mo, 1,000 credits), Professional ($79/mo), and Organization ($119/mo). G2 reviewers give it 4.5/5 across 166 reviews; Capterra rates it 3.8/5 across 46. The Reddit consensus is blunt: "same or better info, way cheaper" than tools like Seamless.AI.
Skip it if you need high-accuracy data without a verification step. One Capterra reviewer called the emails "completely inaccurate" and recommended running all SalesQL output through a separate verifier before sending campaigns. Customer service scores just 3.3/5 on Capterra. In our testing, SalesQL's email output needed a verification pass before we'd trust it for cold outreach - and that extra step eats into the cost savings pretty quickly.

ProsperFleet (Valgen)
Use it if you sell parts, services, telematics, fuel cards, or anything else to commercial fleets. ProsperFleet covers 1.2M U.S. companies with 5+ vehicles, 1.6M locations with fleets, 30M commercial vehicles, and 2.2M contacts - all segmented by light, medium, and heavy duty. Records go through review on a 30-90 day rotating basis with roughly 1M QA calls per month and a 90% accuracy guarantee. No general B2B tool comes close to that level of fleet-specific granularity, and we've looked.
Skip it if you don't sell to fleets. Annual contracts typically land in the $5K-$25K+ range depending on users and download credits. The Salesforce integration is a paid add-on, and the connector is currently one-way only. ProsperFleet has virtually no Reddit presence and just 3 G2 reviews - you're relying heavily on vendor claims for due diligence. For teams outside the fleet vertical, this isn't the right spend.
When You Need Both
Verified Contacts Without Fleet Data
If you don't sell to fleets and just need accurate B2B contact data, neither SalesQL nor ProsperFleet is the right answer.
Prospeo covers 300M+ professional profiles with 143M+ verified emails and 125M+ verified mobile numbers. Email accuracy sits at 98%, data refreshes every 7 days (the industry average is closer to 6 weeks), and you get 30+ search filters including buyer intent and technographic signals. There's a free tier with 75 emails and 100 Chrome extension credits per month, no annual contracts, and self-serve onboarding that takes minutes. We've watched teams go from signup to first outbound campaign in under an hour - try doing that with a tool that requires a sales conversation and annual commitment. (If you're building a full outbound stack, start with these SDR tools and sales prospecting techniques.)
Whether you sell to fleets or not, bad contact data burns domains and wastes quarters. Prospeo gives you 300M+ profiles with 30+ filters - buyer intent, technographics, job changes - at $0.01/email with no annual contract. Free tier included.
Stop paying $5K+ annually for data you can test in minutes for free.
FAQ
Can SalesQL find fleet-specific data?
No. SalesQL pulls general B2B contact data from professional profiles - emails and phone numbers only. It doesn't have fleet size, vehicle type, or DOT number fields. You need a fleet-specific database like ProsperFleet for that intelligence.
Does ProsperFleet include verified emails?
ProsperFleet includes 2.2M contacts with emails and job titles, verified monthly with a 90% accuracy guarantee. For broader B2B outreach beyond fleet contacts, Prospeo offers 143M+ verified emails at 98% accuracy on a 7-day refresh cycle - significantly fresher data.
Is there a free trial for ProsperFleet?
ProsperFleet offers trial access to its online platform and roughly 50-record sample files. Pricing requires a sales conversation - expect annual subscriptions in the $5K-$25K+ range, scaling with users and download credits. For a no-commitment way to test contact data quality first, Prospeo's free tier (75 emails/month) lets you validate workflows before signing an annual deal.
