wow. i usually push back against the mindless "that's too many engineers what are they all doing XDDD" meme. but this is actually insane, i can't believe there's more than a single person working on postman.
They do have other tools with the word API in them but I kinda doubt their usefulness because of gems like "it will move you left on Gartner quadrant" all over Postman "Labs" website. Another reference point - WhatsApp had around 50 engineers when it was sold to Facebook.
