An independent, editorially maintained directory of B2B marketplaces.
B2BSources exists because the existing options — generic listicles, pay-to-play directories, and search-engine summaries — fail the buyer in different ways. We try to fail less. Every entry is editorially reviewed against the same four-point standard, verification claims are checked against what platforms actually do, and monetisation is fully disclosed.
The directory we wished existed when we started sourcing.
Anyone who has tried to find the right B2B marketplace for a specific sourcing need knows the experience: dozens of similar-looking platforms, listicles that recycle the same Wikipedia-grade summaries, directories where every listing claims to be "verified" without specifying what verification means, and Google results dominated by platforms that paid to be there.
B2BSources started with a simple frustration: there was no editorially serious directory of B2B marketplaces. There were trade publications. There were Yellow Pages-style aggregators. There were marketplace-vs-marketplace blog posts written by platforms about themselves. None of these did what a buyer actually needs — tell me which platform fits my situation, what its verification claims actually mean, and where the trade-offs are honest.
So we built it. The standard is straightforward: every entry editorially reviewed against the same criteria, verification claims tested against what platforms actually do, and sponsored placements clearly disclosed wherever they appear. It's slower to scale than a scraped directory, but it produces something a buyer can actually trust.
Four principles we don't compromise on.
Editorial work is mostly judgement, and judgement is mostly principles applied consistently. Here are the four we built B2BSources around — readable in two minutes, defendable across every review on the site.
Things we don't do — that other directories do by default.
Anti-positioning is harder than positioning, but it's where editorial credibility gets built. Here's what we explicitly refuse, set against what's standard practice across the directory landscape.
Most B2B marketplace directories make the same trade — speed and breadth in exchange for editorial standards. We make the opposite trade. Slower, more focused, more editorially defendable.
It means fewer marketplaces listed at any moment. It means we won't rank platforms that haven't been reviewed. It means some popular platforms get listed with "Mixed verification" badges where competitors would just give everyone "Verified."
The bet: buyers can tell the difference. And editorial integrity, applied consistently, compounds in a way that scraped scale never does.
The four-point review applied to every entry.
The same review framework runs on every marketplace, from horizontal giants to specialised pharma platforms. Same questions, weighted by relevance to the platform's category. Specifics live on the methodology page; the headline version is here.
Editorial reviews aren't scored numerically and aren't ranked. What they do is establish whether a marketplace meets the editorial floor for inclusion, and identify which buyer scenarios it serves best.
Reviews are refreshed periodically as platforms evolve. The current cycle is on roughly a 12-month rotation, with priority refreshes triggered by major platform changes (acquisitions, fee model changes, verification policy shifts).
Read the full methodologyFull monetisation disclosure — because trust requires it.
Most B2B directories obscure how they monetise, which makes their editorial claims hard to evaluate. We disclose ours explicitly. If you're going to trust our reviews, you should know what could compromise them — and what couldn't.
What's live, next, and later.
B2BSources is a young directory. Rather than overclaim, here's an honest read on where we are today and what's planned. The roadmap is conservative on purpose — we'd rather ship fewer pages well than more pages badly.
