Why we exist

Why does s90 exist?

Most businesses have someone handling their IT, but nobody accountable for it. Requests get answered and tickets get closed, but nobody owns whether things are getting better. We started s90 to be the ones who own it.

Who's accountable

MBACISM

Sean Crowley is President & Co-Founder of s90, a managed IT provider for businesses and non-profits in south Orange County. He co-founded s90 in 2012 on a simple idea: having someone handle your IT isn't the same as having it managed. Sean brings 25 years in IT, including in-house leadership as a CIO, where he learned that the hardest part of the job isn't fixing problems, it's proving to the people who depend on you that the risk is under control. Today s90's clients receive that proof every quarter, without asking for it.

Proof without asking

What makes s90 different?

Proof isn't something you request from us. It's just something you receive. As a client, you get a Technology Posture Report every quarter, with a Posture Score. If you answer to a regulated framework, you also get a Compliance Posture Report for each one.

How we work

Close enough to show up. Organized enough to prove it.

Your Technology Adviser is your main point of contact. Behind them: service desk engineers for everyday requests, in your office and remotely; centralized services engineers who run monitoring, security and automation; regulatory technology engineers who assess your environment and find the gaps; a compliance operations lead who keeps reviews and evidence on schedule; and project managers and engineers for larger changes. Everyone works from one plan, and your Technology Adviser reviews it with you every quarter.
