Who is on the team, and whether they stay for the whole project
That you own the intellectual property and the source code

How is this ranking worked out?

Each firm's position comes from its client reviews and its profile, blended into one score:

Rating, smoothed so a single five-star review cannot outrank a firm with hundreds of good ones
Review volume, with diminishing returns
Profile completeness: the details a buyer needs to judge the firm
Earned trust: verification and awards, as a small lift

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work
