Contract checks, monitoring, and recovering from mistakes. Every listing says what a company is good for and what to watch out for. Sponsors can buy placement here. They can never buy a rating, and the methodology page says so in writing.
Free to ask, free to be listed. A person reads every request, and we reply either way.

The sponsor slot on this page is unsold. It buys position and nothing else. What that means →
For companies
Free to ask and free to be listed. Paying never gets you in: a listing is decided on its merits first, and placement is only talked about after.
Listings are our own opinion, written by us. Some links are commercial and marked as such — see how we make money. Nothing here is financial advice, and a listing is not a recommendation to use a service.
