How the order works, and what to check
By client rating, weighted for how many reviews stand behind it. A company rated 4.9 across 149 reviews ranks above one rated 5.0 across 8, because the larger sample tells you more. Nothing else moves a company up or down. The criteria below are what to check on each profile before you shortlist.
Verified ratings
Client ratings and review counts read from public review platforms.
Portfolio strength
Depth of shipped work, case studies and the calibre of named clients.
Pricing clarity
Published rates and engagement models buyers can compare before a call.
Team and stability
Team size, seniority mix and how long the company has operated.
Market presence
Momentum in the category and independent recognition.
Score = (reviews × rating + 25 × 4.5) ÷ (reviews + 25)
A company is treated as close to 4.5 stars until it has more than 25 reviews, after which its own rating takes over. Placement cannot be purchased.
Before you shortlist
01How is this ranking ordered?
By client rating, weighted for how many reviews stand behind it. A company rated 4.9 across 149 reviews ranks above one rated 5.0 across 8, because the larger sample tells you more.
02Can a company pay to rank higher?
No. Placement cannot be purchased. The order comes from the rating and review data alone.
03How do I compare prices?
Use the hourly rate filter. Rates are shown as each company publishes them, so treat them as a starting signal and confirm scope before comparing quotes.
