The Oregon Pioneer Savings Landmark Building in downtown Portland seems an unlikely home for Expensify. The online expense-management service was created 10 years ago by CEO David Barrett, who describes its mission as “making expense reports that don’t suck.” The company was founded in San Francisco (and now has offices in London and Melbourne), but it outgrew its original space. Portland, with its laid-back ambience and cheaper real estate, was an attractive alternative for another West Coast office. The stately neoclassical monument, designed by Boston-based Coolidge and Shattuck, was the first building Barrett saw. It has graced a corner site since 1916, with a pedimented Doric colonnade distinguishing its marble-clad front facade and a richly decorated skylit atrium dominating its interior.
