Onetree

Onetree provides tech talent staffing and dedicated team building for companies that need software built without hiring in-house from scratch. Based in Kirkland, Washington, the agency runs nearshore software outsourcing alongside staff augmentation, pairing client teams with developers, designers, and engineers for product design and application development work. Industry focus spans retail and ecommerce, healthcare, and education, with named work including an AI-driven project to improve patient adherence and reduce healthcare costs, and an interactive demographic insights tool built for Harvard.

Services cover the full build cycle: staff augmentation and dedicated teams for scaling engineering capacity, plus product design, product development, mobile app development, web development, and custom software development. Onetree also works in artificial intelligence, building custom AI solutions and applying machine learning within sector-specific projects such as healthcare digitization and EdTech decision tools. Security is handled through a CISO-led framework, with resources operating on encrypted drives as part of the delivery process.
