Without Zapier, we would have needed well over 100 employees today just to do what we're doing. We would have been out of business by now.
David Laderberg, VP of Sales
Without having automation, we would have to at least be double our size. Doubling is a bit of a euphemism β I think we would have died or fallen back into oblivion.
Marcelo Lebre, Co-Founder
Zapier helps us close far above 50% more deals than we would without it. It is a key element of our overall strategy and, therefore, of our sales pitch.
Raphael Bochner, Founder and CIO
Zapier gives us unlimited flexibility and creativity. With Zapier, you're like an artist with a blank canvas. I don't know what we'd do without it.
