Titan Echo

Titan Echo, founded in 2008, provides cost segregation software and services aimed at CPAs and real estate investors. Clients can run parts of the process themselves with the company's mobile field-documentation tools or engage the firm for full-service studies.

The company states it serves properties from about $100,000 to more than $10 million and claims a 100 percent IRS audit success rate. Full-engagement pricing is not published beyond a monthly software subscription.
