About Buk

Buk is a Santiago-based HR technology company whose cloud platform centralises the people processes of companies from five employees to more than 15,000. Its base platform covers organisational structure, reporting and workflows; its people-management pillar runs payroll, attendance, onboarding, digital signatures and a reporting channel; a separate organisational-development pillar covers performance, recruiting, training and surveys; and further modules handle benefits administration and a finance vertical spanning payables, collections and supplier payments. An AI layer runs across the modules for content generation, people analytics and employee assistance. The company emphasises native compliance with Chilean labour requirements and holds ISO 27001 and SOC 2 certifications.

Buk’s January 2025 Series B announcement reported more than 7,000 client companies and over 1.5 million users, with clients outside Chile doubling year after year. The US$50 million round, led by Headline with Workday, Greenoaks, Base10 and Endeavor Catalyst participating, valued the company at about US$850 million and funded the official launch of its Brazil operation, a larger sales and marketing effort, its benefits ecosystem and continued research and development. Total reported funding is about US$135 million, including a US$50 million Series A in 2021 and a US$35 million round in 2023 — an unusually US-backed cap table for a company selling Latin American HR compliance.
