Peter Rinearson

By 2018, Rinearson was a member of the advisory board of Athira Pharma, a Seattle company developing a potential therapy for chronic, progressive neurodegenerative diseases such as Alzheimer's and Parkinson’s. The drug was in clinical trials in the United States and France.

Rinearson was a co-executive producer of Wakefield, a Robin Swicord movie (based on a short story by E.L. Doctorow) starring Bryan Cranston and Jennifer Garner. It was released on May 19, 2017.

After Microsoft, Rinearson returned to his entrepreneurial roots, where he undertook projects that converged into Intersect.com, a service he founded that launched in December, 2010 and closed in 2013. Intersect was a social network with a strong privacy model that let photos and other stories be posted or discovered at specific times and places. So, for example, photos taken at a school event by various parents (who might be strangers to each other) could be found and shared by looking at the time and place of the event. Postings also could be viewed and discovered on intersecting timelines, called storylines. This was a year before Facebook introduced its timelines, and when Mark Zuckerberg announced Facebook’s forthcoming feature in 2011, Rinearson downplayed its importance. “As best we can tell, Facebook offers you only one timeline, it doesn’t appear to let you borrow content from other people, it doesn’t have Intersect’s interesting and entertaining ways of exploring time and place, and it doesn’t let you discover lives and stories that intersect with yours,” he said. . Intersect was a success technologically but, despite Rinearson’s initial confidence, could not gain traction against Facebook.

Rinearson is inventor on eight issued U.S. patents, granted between 2006 and 2017.

Two years later, Rinearson spun off from Alki a subsidiary, Intype, which created Babynamer.com, which had 300,000 monthly visitors. But the primary initiative of Intype was to build and market a Web-publishing platform that would enable a web site to offer a blend of professional and community created content. (This was before the word "blog" existed.) Rinearson believed that the economic principle called network effects would catapult to dominance publishers who owned the primary places where people congregated online to create and consume their own content. Intype was an attempt to get the newspaper industry, where Rinearson had started his career, to embrace community content before Web startups gained a strong foothold. The Newspaper Association of America used Intype's technology, but when no newspapers followed suit Rinearson sold Intype to Oxygen Media in 1999.

From 1995 to 1999, Rinearson assisted Bill Gates in writing a newspaper column carried by the New York Times Syndicate.

In 1995, Rinearson co-founded a nine-person digital design company, Raster Ranch, that focused on 3D modeling for television, games, and the Web.

In 1988, Rinearson founded Alki Software, which created third-party products for Microsoft Word. Alki licensed to Microsoft the toolbar and several other features of Microsoft Word version 5.1 for the Macintosh, and for more than a decade sold the Foreign Proofing Tool kits that allowed people to work with Word in multiple languages.

Rinearson spent his 20s writing for the Seattle Times, for which he covered politics, Boeing, and Asia. In 1984, Rinearson won the Pulitzer Prize for Feature Writing for a series he wrote on Boeing's development of the 757. Two years after winning the Pulitzer, he left the Times to write books.

The Pulitzer Prize Board announced a new category of "Explanatory Reporting" in November 1984, citing Rinearson's series of explanatory articles that seven months earlier had won the Pulitzer Prize for Feature Writing. The series, "Making It Fly," was a 29,000-word account of the development of the Boeing 757 jetliner. It had been entered in the National Reporting category, but judges moved it to Feature Writing to award it a prize. In the aftermath, the Pulitzer Prize Board said it was creating the new category in part because of the ambiguity about where explanatory accounts such as "Making It Fly" should be recognized.

Previously in the 1980s, Rinearson wrote how-to books on using Microsoft Word in MS-DOS, for Microsoft Press. Of one of these, New York Times reviewer Erik Sandberg-Diment wrote: "Word owners should not be without Rinearson's book, even if they read no more than a tenth of it." According to Rinearson's official bio at his company, he "created the first software disk to accompany a Microsoft Press book, which presented a system of styles and style sheets that Microsoft later commissioned him to revise for Word for Windows. This work laid the foundation for the formatting styles built into Word today."
