These are the 20 largest business incubators and accelerators in Oregon and Southwest Washington
The largest business incubators and accelerators in Oregon and Southwest Washington have more than 8,500 portfolio companies (total current companies and graduated companies). The online version of this ranking expands beyond what appears in print; another 4 organizations are included in our digital rankings, in addition to the 16 featured in this week's print edition. This week's List is part of a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ's footprint — this year alone. Information on The List was obtained through Portland Business Journal research or supplied by individual organizations through questionnaires that the PBJ could not independently verify. In case of ties, organizations are ranked by total employment and then listed alphabetically if ties remain. Additionally, organizations that did not respond to surveys but were still included on this year's List are sorted by estimated total employment figures derived from PBJ archives; annual 990 filings with the IRS; and other organization-specific resources. Inclusion on this year's List required each organization to have a minimum of 2 total employees, using the methodologies described above.
