Sparklane vs ProsperFleet (Valgen): Which B2B Data Tool Fits Your Stack?
Sparklane and ProsperFleet by Valgen solve fundamentally different problems. One's a French B2B lead scoring platform built for European prospecting. The other's a US fleet database covering 30M vehicles, with fleet-specific filters like duty class, cargo carried, and fleet size brackets. This comparison might be the only one you'll find online - because these two tools barely overlap. If you're weighing them against each other, there's a decent chance neither is quite right for what you actually need.
30-Second Verdict
ProsperFleet wins if your ICP is US fleet operators and you need vehicle-attribute filtering that general B2B databases don't offer. Sparklane wins if you prospect across Western Europe and want lead scoring driven by business signals. Skip both if your real problem is bouncing emails and dead phone numbers across any industry - a general-purpose data platform with verified contacts will serve you better.
What Is Sparklane?
Use this if you're a sales team targeting B2B accounts in France and Western Europe and want lead scoring baked into your prospecting workflow. Sparklane ingests over 3M business signals per year across seven countries - France, UK, Belgium, Germany, Spain, Netherlands, and Italy - and uses them to score and prioritize accounts.
The Discover plan starts at EUR 44/mo per user on an annual commitment, which is reasonable for a European-focused tool with 40+ targeting criteria and a Chrome extension. Sparklane was founded in 2009, acquired by Ellisphere in 2021, and runs about 36 employees. 6sense estimates roughly 61 customers, about 73% of them in France. It's rated 4.1/5 from 12 reviews on G2, with users praising ease of use but noting that incorrect email addresses show up sometimes.
Skip this if you need US data or global reach. It simply doesn't have it.
What Is ProsperFleet (Valgen)?
Use this if you sell to companies that operate vehicle fleets in the US - trucking firms, delivery services, construction companies, government agencies. ProsperFleet covers 30M vehicles, 1.2M companies, 1.6M locations, and 2.2M contacts. The filtering is fleet-specific: duty class (Light 1-3, Medium 4-6, Heavy 7-8), fleet size, cargo carried, for-hire vs. private, and geography down to radius around a ZIP code.
Since 90% of companies with vehicles have only one or two, ProsperFleet's 5-vehicle minimum filters out a massive amount of noise fast. Data freshness is solid - Valgen makes roughly 1M phone calls per month to review records on a rotating basis, with many records reviewed within 30-90 days and most of the remainder within six months. They also run monthly address updates and monthly email verification. They offer a 90% accuracy guarantee: if you hit 10%+ hard bounces, they replace the records.
Rated 4.0/5 from 3 reviews on G2. A common complaint is that filters can feel limited when you need to drill down further. Pricing isn't public, but it's sold as an annual subscription based on users plus download credits - credits are based on companies downloaded, not contacts. Expect mid-four to five-figure annual pricing depending on seats and credit volume. Skip this if your ICP isn't fleet-specific. It's not designed for general B2B prospecting and it won't pretend to be.
Sparklane covers 7 EU countries. ProsperFleet covers US fleets. Neither gives you verified contacts across every industry and geography. Prospeo's 300M+ profiles, 98% email accuracy, and 7-day refresh cycle work whether your ICP is fleet managers, French mid-market, or anything in between - at $0.01 per email.
Stop paying five figures for a database you'll outgrow in a year.

One practical note on integrations: HubSpot integration is included free on all ProsperFleet plans, but Salesforce is a paid add-on and currently one-way only. If your team runs Salesforce, budget for that extra cost.
When to Use Which
Choose ProsperFleet if your ICP is mid-to-large US fleet operators with 5+ vehicles and you need fleet and vehicle-attribute data that general B2B tools don't prioritize. For context, FMCSA data covers roughly 686K companies, but 54% are single-vehicle owner-operators and only about 12,600 fleets have 50+ power units. ProsperFleet's value is that it includes light-duty fleet intelligence and broader coverage than FMCSA-heavy trucking lists.
Choose Sparklane if your ICP is European B2B (especially France), you want lead scoring and business signals integrated into prospecting, and you don't need US coverage at all.
Here's the thing, though: most people weighing this comparison don't need either tool exclusively. Both are niche. If your ICP spans multiple industries or geographies, you need verified contact data that works across any vertical - not a database you'll outgrow in a year.
Niche Data Is Overrated for Most Teams
Let's be honest. Unless your entire revenue depends on fleet operators or French mid-market accounts, locking into a niche database is the wrong move. The teams we've seen get the best ROI from prospecting tools are the ones that pair broad, accurate contact data with their own ICP filters - not the ones paying five figures annually for a database they've outgrown in 18 months. We've watched this pattern play out dozens of times: a team buys a vertical database, uses 30% of it, then spends another chunk of budget on a second tool to cover everyone else.
Verified Contact Data for Any Prospect
Neither Sparklane nor ProsperFleet solves the universal problem of bouncing emails and disconnected phone numbers. Prospeo covers 300M+ professional profiles with 98% email accuracy and 125M+ verified mobile numbers on a 7-day refresh cycle. You can use it as a standalone prospecting platform or as a contact data layer paired with ProsperFleet's fleet accounts - pull fleet company lists from Valgen, then enrich decision-maker contacts through Prospeo's enrichment API at a 92% match rate. The free tier gives you 75 verified emails per month, self-serve, cancel anytime.
If you're comparing tools like this, it's also worth sanity-checking your broader sales prospecting database options and whether you need dedicated data enrichment services versus a single platform.
Pull fleet company lists from ProsperFleet, then enrich every decision-maker through Prospeo's API at a 92% match rate with 50+ data points per contact. 125M+ verified mobile numbers with a 30% pickup rate mean you actually reach the ops director, not their voicemail.
Pair niche account lists with contacts that actually connect.

Can Sparklane be used for US prospecting?
No. Sparklane covers France, UK, Belgium, Germany, Spain, Netherlands, and Italy exclusively. It has zero US data. For US or global prospecting, you'll need a platform with broader coverage, like Prospeo's B2B database with 300M+ profiles.
Is ProsperFleet's Salesforce integration included?
No. Salesforce integration is a paid add-on and currently one-way only (ProsperFleet to Salesforce). Bidirectional sync is in progress but isn't live yet. HubSpot integration is included at no extra charge on all plans.
