In a significant move for the HR and payroll industry, San Francisco-based Gusto, a leading provider of payroll and human resources software, has announced its agreement to acquire Guideline, a retirement benefits startup specializing in 401(k) plans for small businesses.
This acquisition, reported on August 27, 2025, marks a strategic expansion for Gusto, a company already valued at nearly $10 billion, as it seeks to bolster its offerings in the small business benefits sector.
Gusto and Guideline: A Strategic Partnership Evolves
The deal brings together two companies that have long been partners, now uniting under one roof to create a more seamless experience for small and medium-sized businesses (SMBs).
Guideline, based in Burlingame, California, serves over 1 million people and 65,000 businesses, providing accessible and tailored retirement plans, a critical need for SMBs often overlooked by larger financial institutions.
Impact on Small Businesses: A Unified Solution
The merger promises to deliver a unified HR, payroll, and retirement benefits platform, potentially simplifying operations for business owners who juggle multiple vendors.
Historically, small businesses have struggled with limited access to affordable, high-quality retirement plans, a gap that Guideline has worked to close since its founding in 2015.
Gusto, established in 2011, has built a reputation for empowering SMBs with intuitive payroll and HR tools, and this acquisition signals its ambition to become a one-stop shop for business needs.
Financial Details and Industry Shifts
While initial reports did not disclose the financial terms, recent updates suggest Gusto paid approximately $600 million for Guideline, a figure notably below Guideline’s last valuation of $1.15 billion, yet still profitable for many investors.
This deal reflects broader shifts in the 401(k) industry, where technology-driven solutions are increasingly critical to meeting the needs of a growing SMB market.
Looking ahead, Gusto’s integration of Guideline could set a new standard for how HR tech companies approach benefits, potentially pressuring competitors to expand their offerings.
However, challenges remain, as Gusto reportedly plans to divest customers linked to rival platforms, a move that could complicate the transition for some users.
Ultimately, this acquisition positions Gusto as a formidable player in the HR and benefits space, with the potential to redefine support for small businesses in the years to come.
