"Take, for example, Lendio, an organization located in Jordan, Utah, a Salt Lake suburb. Lendio helps budding entrepreneurs acquire small business loans.

Blake kicked off the week by laying a 'gorgeous BYU football field' (with real grass) in the lobby.

But instead of his own cell number, he posted his Utah co-worker's number, with a note that interested buyers should 'only call between the hours of 11:30 p.m. and 6 a.m., because I work graveyard and I sleep all day.'"
