Our Story

Why we call it coral.

We rate office spaces not with stars, but with Coral Stones.

Because coral, we found, bears a striking resemblance to a good space —
It is demanding: a little murk or a degree off and it will not thrive, like how we refuse to settle on standards;
It is a habitat: a reef shelters a quarter of marine life, like how many people a good office space can hold;
It lives by symbiosis: coral and its algae cannot do without each other, like coworkers making each other possible;
It builds itself: a reef is grown bit by bit, like a good space earned over years;
And it lasts: a reef can nourish for centuries — the kind of good we want to rate is the kind that lasts.
