We build this list each month from public records: funding rounds, government contracts, launches, valuations and company milestones. It shows the companies whose records gained the most in the last six months. Each event shown has a date and a public source.
No altitude gets more than three companies. No one pays to be listed, and no one picks the companies by hand.
