About
Buk is a Santiago, Chile-based HR technology company founded in 2017 by Alejandro Burr and Jaime Arrieta. The platform provides an end-to-end human resources management suite designed specifically for the Latin American market — covering payroll processing, electronic contracts and e-signatures, employee settlements, performance reviews, talent management, work environment surveys, and talent acquisition. Buk was built to address the complexity of HR and payroll compliance in Latin America, where labor law requirements, tax structures, and settlement calculations vary significantly across countries and frequently change, making payroll particularly difficult to manage with generic global platforms.
Businessolver (Des Moines IA) is an independent benefits administration platform combining Benefitsolver SaaS with human advocacy, serving large US employers from enrollment through ACA compliance.
About
Businessolver is a Des Moines, Iowa-based benefits administration company that combines SaaS technology with a people-powered advocacy model to help employees understand, choose, and use their benefits effectively. Founded in 1998, the company has grown into one of the largest independent benefits administration platforms in the United States, serving employers with workforces ranging from a few thousand to hundreds of thousands of employees. Its flagship product, Benefitsolver, provides end-to-end benefits administration including enrollment, eligibility management, COBRA, ACA compliance, and carrier data exchange, all within a highly configurable cloud platform.\n\nA defining characteristic of Businessolver's approach is its Sofia AI chatbot and 24/7 employee advocacy service, which goes beyond self-service enrollment to actively guide employees through benefits decisions, coverage questions, and claims navigation year-round. This advocacy layer is particularly valuable for complex multi-population workforces—hourly workers, union employees, and those with limited digital literacy—who are often underserved by traditional benefits administration platforms built for white-collar desk workers. Businessolver reports consistently high employee engagement rates with its advocacy services, and customers often cite improved benefits utilization and reduced HR support burden as key outcomes.\n\nBusinessolver has won recognition for its culture and workplace environment, which the company argues is the foundation for building empathy-driven HR technology. The platform integrates with hundreds of insurance carriers, third-party administrators, and payroll providers through a managed data exchange network, reducing the EDI implementation burden that has historically plagued benefits administration projects. Competing primarily with Bswift, Benefitfocus, and large HCM vendors, Businessolver differentiates on its advocacy depth and its track record with large, complex employer populations.
