280 North builds web application tools centered on Cappuccino, an open-source framework paired with Objective-J that lets developers create rich web applications using patterns from desktop development environments. Its first product, 280 Slides, lets anyone build and share presentations in a browser, with support for importing and exporting PowerPoint files. The framework handles the heavy lifting that would otherwise require custom front-end engineering from scratch. | B2B | 11 |

A Thinking Ape builds social strategy mobile games designed to sustain large online player communities over many years.

The service targets anyone who maintains a personal site and wants their identity and content to travel with them, replacing the dependency on any one network as the hub. | Consumer | 2 |

FathomDB delivered relational databases as a managed cloud service, handling routine database administration tasks so that DBAs could focus on higher-order problems. It was an early provider of MySQL-as-a-service on Amazon and Rackspace, and contributed to OpenStack's database-as-a-service component. FathomDB later joined Meteor, which extended the same goal of simplifying data and database work into a full real-time application platform. | B2B | Not listed |

Joberator builds a specialized job marketplace connecting STEM graduates and professionals with employers hiring in science, technology, engineering, and math.

Employers post jobs, search candidate profiles, and manage outreach and interviews end-to-end, replacing fragmented general-purpose recruiting tools with a single STEM-focused workflow. | B2B | 2 |
| ||
Kirkland North builds and operates Turf, a campus-wide competitive game that divides a university into geographic sections and pits them against each other in a battle for campus domination.

Target customers are colleges and universities seeking engagement across their student populations. | Consumer | 2 |

Machine Zone builds global multiplayer mobile games and the live data infrastructure that runs them.

Ninite builds a Windows app installation and patching tool that lets users select multiple applications and install or update them all at once, without toolbars, bundled software, or manual next-click prompts.

It replaces the manual work of visiting individual vendor sites, running separate installers, and tracking version updates. | B2B | 2 |
| ||
Omnisio built a web-based tool that let users annotate, structure, and share online video from any site, replacing manual workarounds for adding context or navigation within hosted video. A slide-syncing feature paired video with presentation slides via SlideShare. Google acquired the company through YouTube shortly after launch. | Consumer | Not listed |
| ||
RescueTime builds time-tracking and focus software for individuals and teams.

Snaptalent runs a distributed job ad network focused on developer recruitment. Employers submit listings that are then displayed across a network of participating sites.

| ||
Trigger builds a cross-platform mobile development framework that lets web developers ship native mobile apps using HTML5, replacing the need to write separate native codebases for each platform.

| ||
Wundrbar builds an enhanced browser search bar that replaces the standard address and search field with an inline command interface.
