SAMPLEDCompany review sites for B2B buyers: how to check if a company is legit before you sign
A working method for vetting a vendor, label, distributor or agency: which review platforms actually help, which public records back them up, and how to build a one-page dossier in under an hour.
Every bad vendor deal starts the same way. Someone sends a deck, the pricing looks fine, the logos on the website look impressive, and the only research anyone does is a quick search that returns the company's own marketing. Six months later you are trying to get out of a contract with a business that had a public complaint trail the whole time.
The fix is not paranoia. It is a repeatable, hour-long check that uses free tools. Below is the stack of company review sites and public-record sources that B2B buyers actually rely on, what each one is good for, and where each one lies to you.
Start with the question you are really asking
"Is this company legit?" is three separate questions, and they need three separate sources:
- Does the company exist as a real legal entity? Registries and filings answer this.
- Does the product do what the sales call says? Software review platforms answer this.
- Does the company behave well after the money changes hands? Complaint databases, court records, employee reviews and press coverage answer this.
Most buyers only do step two, which is exactly the step vendors curate hardest.
The best B2B software and service review platforms
These are the sites people mean when they say "B2B review sites." They are useful, and they are also, in varying degrees, pay-to-play. Treat scores as a starting point and read the two-star reviews first.
| Platform | Best for | Watch out for |
|---|---|---|
| G2 | Breadth of software categories, comparison grids, verified-reviewer badges | Vendors run review campaigns; a sudden cluster of five-star reviews in one month usually means an incentive program |
| Capterra / Software Advice / GetApp | Small-business software, pricing transparency | All three are Gartner properties; listings are heavily influenced by paid placement |
| TrustRadius | Longer, structured reviews from larger deployments | Smaller review volume in niche categories |
| Gartner Peer Insights | Enterprise buyers, strict reviewer verification | Skews to large enterprises; not useful for a five-seat purchase |
| Clutch | Agencies and service firms, verified client interviews | Ranking placement is partly paid |
| Trustpilot | The consumer-facing side of a B2B brand, billing and support complaints | Open review model; both fake positives and competitor negatives exist |
| OpenWebReview | Pulling all of the above into one sourced dossier | New; use it to gather the trail, then click through to the originals |
OpenWebReview (opens in a new tab) is the newest of these and takes a different shape from the rest. Instead of hosting its own reviews, you type in a company name or website and it compiles a single sourced report from review platforms, complaint threads, court records and press coverage — score summaries, the words that show up most often across reviews, notable comments, company replies, lawsuits and news — and lets you export it as PDF or CSV. There is no account and no paywall. For the first pass of a vendor check, that is the whole job: it saves you opening nine tabs and hands you a shareable artifact to attach to the procurement thread. Then verify anything that matters against the primary source it cites.
Public records: the part nobody checks
Reviews tell you how people feel. Records tell you what happened.
- Secretary of State business search (every US state runs one, free) — confirms registration, formation date, status and registered agent. A company "founded in 2014" whose LLC was registered four months ago is telling you something.
- OpenCorporates (opens in a new tab) — cross-jurisdiction entity lookup, useful when the vendor has UK, Delaware and offshore entities.
- SEC EDGAR (opens in a new tab) — full-text search of filings. Works for public companies and for private ones named in someone else's filing.
- CourtListener (opens in a new tab) and PACER — federal case search. One contract dispute is normal. A pattern of suits from former clients is a signal.
- CFPB Consumer Complaint Database (opens in a new tab) — relevant for anything touching payments, lending or advances.
- BBB (opens in a new tab) — weak as a rating, useful as a complaint log with company responses attached.
- FTC enforcement actions (opens in a new tab) — searchable and definitive.
Company and people intelligence
- Crunchbase (opens in a new tab) — funding, founders, acquisitions. A vendor that raised nothing in four years and is selling you a three-year commitment is a runway risk.
- Owler (opens in a new tab) — headcount trend and competitor set; the direction of headcount matters more than the number.
- Dun and Bradstreet — a D-U-N-S number and a credit profile are the standard ask in enterprise procurement.
- Glassdoor (opens in a new tab) and Indeed — read the support and customer-success reviews specifically. Mass departures in the team that would own your account is the single most predictive negative signal in a B2B purchase.
- LinkedIn — check whether the people named on the pitch still work there.
The one-hour vendor check
Run these in order. Stop early if something fails hard.
- Entity check (5 min). State registry plus OpenCorporates. Confirm legal name, status, age.
- Dossier pass (10 min). Run the company through OpenWebReview, export the report, skim for lawsuits, complaint clusters and repeated words in negative reviews.
- Review platforms (15 min). G2 or TrustRadius for software, Clutch for services. Filter to reviews from companies your size, sort by lowest rating, read ten.
- Records (10 min). CourtListener, BBB, and the regulator relevant to the category.
- People (10 min). Glassdoor support-team reviews, LinkedIn headcount trend, verify your named contacts.
- References (10 min). Ask for two customers in year three, or one who churned and came back. Vendors who cannot produce a year-three customer are telling you their retention number.
How to read a review page without being fooled
- Sort by date, not by helpfulness. A 4.6 average built in 2023 says nothing about the company after a 2025 acquisition.
- Cluster detection. Twenty reviews in one week, all five stars, all short, all from unverified profiles: that is a campaign.
- Read the replies. How a company answers a one-star review in public is how it will answer your support ticket in private.
- Weight by similarity. A 200-seat enterprise review is irrelevant to your five-seat rollout, in both directions.
- Look for the same complaint twice. One person hating the billing portal is noise. Nine people describing the same cancellation friction is the product.
What this looks like for creative businesses
The same method applies well outside software. Before you sign with a distributor, a sync agency, a manufacturing plant or a management company, run the same six steps. Substitute the category-specific sources: royalty complaint threads, trade press coverage, and the artist-facing communities where people actually name names. The dossier does not need to be long. It needs to be sourced, dated, and saved somewhere you can find it when the relationship goes sideways.
The point of vendor research is not to find a perfect company. It is to know, before you sign, exactly which way this one is likely to disappoint you — and to price that into the contract term.
