Jeff Samuelson has spent over 35 years at the intersection of business, missions, and discipleship. Together with his wife Julie, Jeff served as a field missionary for 13 years across China, East Asia, and Singapore, where he witnessed firsthand the power of marketplace enterprise as a vehicle for gospel transformation in the world's most challenging environments.

During their time in Asia, Jeff served as the Pioneers in Asia Director, leading field strategy and team development across the region. That experience laid the foundation for the next 17 years of building, training, and coaching within the business-as-mission movement, including the last eight years serving full-time with iBAM.

Jeff now serves as Director of Third Fish Academy (thirdfish.org), an iBAM initiative offering a free online platform that equips followers of Jesus with the practical skills and biblical framework to launch and grow small businesses as tools for Kingdom impact. Third Fish Academy is growing as a key resource for churches, missionaries, and marketplace believers worldwide.

Jeff's passion is multiplying disciples of Jesus Christ through local small business ownership — believers who see their marketplace calling as an extension of the Great Commission. His current work spans field partnerships in Indonesia, Central Asia, and Central Africa, connecting business training with church-planting movements reaching unreached people groups. Past work includes engagement across at least ten other nations and multiple people groups.

Jeff and Julie live in the Pacific Northwest and remain self-funded missionaries, sustained by the faithful generosity of churches and individuals who share their vision.
