For more than half a century, small business payroll in the United States was dominated by a calcified corporate duopoly: Automatic Data Processing (ADP) and Paychex. Legacy payroll providers treated America's 33 million small business owners with open contempt: software interfaces were clunky, monochrome mainframes dating back to the 1990s; customer support meant waiting on hold for two hours; and contracts were riddled with hidden fees for quarterly tax filings, W-2 generation, and direct deposit batches. If a small business owner made a single clerical error on a local municipal tax withholding, the legacy provider refused to take responsibility, leaving the small business owner facing aggressive penalties and audits from the IRS. Small business owners endured this abuse because calculating payroll taxes across thousands of local jurisdictions by hand was impossible.
In 2011, three Stanford engineering alumni—Joshua Reeves, Tomer London, and Edward Kim—decided to bring human warmth, modern software design, and radical transparency to the payroll industry. They founded ZenPayroll, subsequently rebranding to Gusto in 2015. By automating 50-state tax filings with zero hidden fees and designing an intuitive, joyful smartphone interface that allowed a business owner to run payroll in 90 seconds, Gusto sparked an unstoppable movement. Scaling into a $9.5 billion people platform generating over $500M in annual revenue, Gusto became the beloved champion of over 300,000 American small businesses, permanently dislodging legacy payroll monopolies from Main Street America.

Origins: The Stanford Trio & The Famous Shoe-Less Office
The institutional story of Gusto is rooted in the personal values of its three founders. In 2011, Stanford engineering alumni Joshua Reeves, Tomer London, and Edward Kim lived in a house in Palo Alto. Reeves came from a family of small business entrepreneurs and had watched his relatives struggle with payroll headaches for years. When the three founders looked at the payroll software market, they were appalled: legacy providers treated customers with bureaucratic coldness, charging arbitrary fees and locking businesses into archaic contracts.
The founders entered Y Combinator in the Winter 2012 batch with a mission to build software with a human soul. They instituted a unique corporate ritual that became famous throughout Silicon Valley: the Shoe-Less Office. When employees and guests entered Gusto's office, they took off their shoes and put on comfortable socks or slippers. The tradition symbolized a home-like environment of humility, equality, and radical care. Joshua Reeves insisted that every customer support representative spend as much time on the phone as needed to solve a small business owner's problem, refusing to enforce call-duration quotas. That extreme customer empathy ignited explosive organic word-of-mouth growth across Main Street America, transforming Gusto into an iconic brand trusted by hundreds of thousands of businesses.
Gusto Embedded: Becoming the 'Stripe of Payroll'
While Gusto built an empire serving small businesses directly, its most transformative technological innovation of the 2020s was Gusto Embedded Payroll. For years, vertical software platforms—such as Toast (point-of-sale for restaurants), ServiceTitan (operating software for HVAC technicians and plumbers), and 7shifts (restaurant scheduling)—wanted to offer payroll to their clients, but building a 50-state compliant payroll engine required a decade of legal work and hundreds of millions of dollars in engineering.
Gusto transformed its proprietary payroll and tax calculation infrastructure into an open developer API. Through Gusto Embedded, vertical software platforms can deploy a fully white-labeled, pre-built payroll workflow inside their own application with minimal code. In 2023, Gusto achieved the ultimate enterprise validation: JPMorgan Chase selected Gusto Embedded to power native payroll inside Chase Business Online, giving millions of Chase commercial banking customers access to Gusto payroll directly from their bank dashboard. By transforming its compliance engine into an open utility, Gusto became the indispensable 'Stripe of Payroll', securing a massive, low-cost distribution channel that continues to compound at light speed.

Municipal Tax Fragmentation: The Algorithmic Nightmare of 3,000 Local Jurisdictions
To understand why building a nationwide payroll platform in the United States is one of the most technologically grueling feats in software engineering, one must analyze the madness of American municipal taxation. In the United States, payroll taxes are not determined solely at the federal level: there are 50 sovereign state tax departments, and beneath them, over 3,000 local municipal jurisdictions, counties, school districts, and transit authorities that levy hyper-local payroll taxes (such as Pennsylvania's local earned income taxes, Ohio's municipal tax codes, and New York City's commuter taxes).
Co-founder Edward Kim engineered a proprietary Automated Municipal Tax Engine that eliminated this complexity for small business owners. When a small business hires an employee in rural Ohio or suburban Pennsylvania, Gusto's geocoding engine identifies the exact tax district down to the employee's residential rooftop address. The system automatically calculates municipal withholding rates, files electronic quarterly tax returns with local city treasurers, and remits tax impounds automatically. If a local municipality updates its tax rate, Gusto's legal rules engine updates the calculation across all affected accounts instantly. By assuming 100% legal responsibility for tax calculation accuracy and shielding small businesses from IRS and state tax penalties, Gusto removed the single greatest source of dread from small business ownership.
The Paycheck Protection Program (PPP) Sprint: Saving 100,000 Main Street Businesses
A defining, legendary chapter in Gusto's corporate history occurred in March 2020 during the outbreak of the COVID-19 pandemic. As government-mandated lockdowns shut down restaurants, salons, and retail shops across America, Congress passed the historic CARES Act, creating the Paycheck Protection Program (PPP)—a $659 billion forgivable emergency loan program designed to help small businesses keep workers on payroll. However, to qualify for PPP loans from the Small Business Administration (SBA), business owners had to submit complex, highly technical historical payroll expense reports within days.
Small business owners were panicked: legacy payroll providers like ADP and Paychex had no automated tools, leaving customers stranded on hold for hours. Joshua Reeves and the Gusto engineering team worked around the clock over a 72-hour weekend sprint, writing code to build an Automated PPP Loan Application Report Generator. With a single click inside Gusto, business owners could generate pre-formatted, SBA-compliant payroll verification documents showing their exact average monthly payroll costs. Over the ensuing weeks, Gusto helped over 100,000 small businesses secure more than $2.5 billion in emergency forgivable federal loans, saving hundreds of thousands of American jobs and cementing Gusto's reputation as the heroic, indispensable ally of Main Street America.
Gusto Wallet and Early Wage Access: Eliminating Predatory Payday Loans
In the United States, over 60% of working adults live paycheck-to-paycheck. When an unexpected emergency strikes—such as an urgent car repair or medical bill—traditional bi-weekly payroll cycles create severe financial crises: employees are forced to turn to predatory payday lenders who charge annualized interest rates exceeding 400%, or incur $35 bank overdraft fees that trap families in cycles of debt.
Gusto mounted a direct technological intervention on behalf of workers by launching Gusto Wallet and Early Wage Access (Gusto Cashout). Because Gusto's core platform tracks hours worked and earnings in real time, Gusto allows employees of participating businesses to access a portion of their already-earned wages before their scheduled payday. Unlike predatory payday loan apps or fee-heavy competitors, Gusto Cashout charges zero interest and zero predatory hidden fees, automatically deducting the advanced wages from the employee's next regular direct deposit. Gusto Wallet provides employees with automated savings vaults that automatically round up spare change and set aside money into high-yield savings accounts, transforming payroll from a passive bi-weekly transaction into an empowering personal financial health platform for over 3 million working Americans.
Pay-As-You-Go Workers' Compensation: Replacing Lump-Sum Estimates with Precision
In traditional commercial business operations, obtaining mandatory workers' compensation insurance was a painful financial drain for small business owners. Traditional commercial insurance carriers forced small businesses to pay massive, upfront annual premium estimates at the beginning of every policy year. At the end of the year, insurance companies conducted invasive, tedious annual audits: if the small business hired more employees than anticipated, they were slapped with huge retroactive audit bills.
Gusto revolutionized commercial insurance by pioneering Pay-As-You-Go Workers' Compensation. Integrating its licensed digital insurance brokerage directly with its live payroll engine, Gusto connects to premier insurance carriers (such as The Hartford, AmTrust, and Travelers). Instead of demanding massive upfront deposits, Gusto calculates the exact workers' compensation premium owed every single pay period based on actual, verified wages paid to specific employee risk classes, automatically deducting and remitting the micro-premiums with each payroll run. This eliminated large lump-sum premium shocks, preserved critical working capital for small businesses, and completely eradicated painful year-end audit surprises, delivering unprecedented financial peace of mind to entrepreneurs.
Gusto Talent: Streamlining Hiring and Onboarding for Main Street Employers
For independent small business owners—such as an artisanal bakery opening a second location, a local dental practice expanding its hygiene team, or an architectural design studio hiring junior drafters—recruiting and onboarding was historically an exhausting, paper-heavy nightmare. Small business owners had to post job descriptions on multiple expensive job boards, download dozens of PDF resumes into chaotic email folders, and print out thick stacks of federal Form W-4 and Form I-9 paperwork for new hires to sign on their first day of work.
Gusto eliminated this administrative drag by introducing Gusto Talent and Automated Onboarding. Small business owners can create professional job postings, publish them to major job boards with a single click, and track applicants through an intuitive, visual hiring pipeline directly within Gusto. Once a candidate is selected, Gusto generates an official digital offer letter with electronic signature tracking. The moment the candidate signs, an automated self-onboarding portal is triggered: new employees complete their federal W-4 tax withholdings, upload direct deposit bank credentials, complete identity verification for Form I-9, and select health insurance plans on their smartphone before their first day on the job. By turning first-day administrative onboarding into an effortless digital experience, Gusto allowed small business owners to focus on mentoring their new team members rather than filing paperwork.
The Denver Operations Campus: Scaling Customer Advocacy at Scale
In modern enterprise software, high-growth technology companies routinely outsource customer support to low-cost offshore call centers, subjecting frustrated customers to robotic phone scripts and endless transfers. When Gusto began scaling past 100,000 small business clients, industry advisors urged CEO Joshua Reeves to follow suit, warning that maintaining in-house customer support in expensive coastal markets like San Francisco would crush operating margins.
Reeves completely rejected this advice, making a landmark strategic commitment to customer care by establishing a massive regional operating campus in Denver, Colorado. Located in the historic 16th Street Mall district, Gusto's Denver campus grew into a 1,000-person powerhouse of customer success advocates, certified payroll specialists, and licensed health insurance brokers. Gusto instituted a non-negotiable service principle: customer support representatives are never evaluated on call duration quotas; instead, they are empowered to stay on the phone for an hour or coordinate directly with state tax agencies on behalf of a small business owner until their problem is completely resolved. This extraordinary operational investment in human empathy established Gusto's legendary reputation across Main Street America, yielding industry-shattering Net Promoter Scores (NPS) exceeding 70—unheard of in the financial services sector.
The JPMorgan Chase Alliance: Transforming Commercial Banking Payroll
In the financial services landscape, the relationship between commercial banks and third-party payroll providers was historically contentious: legacy banks offered clunky, third-party white-labeled payroll tools that were universally despised by business banking clients, leading to high account churn. When JPMorgan Chase—the largest commercial bank in the United States—sought to modernize its small business banking suite, it evaluated building its own payroll platform from scratch versus partnering with an established leader.
In 2023, JPMorgan Chase forged a historic, multi-year strategic alliance with Gusto, selecting Gusto Embedded Payroll to power native payroll services directly inside Chase Business Online banking for millions of small business checking accounts. Under the partnership, a small business banking client can log into their Chase commercial bank account, view their operating cash balance, and run automated 50-state payroll with direct deposit in seconds, with tax withholdings automatically debited from their Chase checking account. For Chase, the partnership delivered a modern, consumer-grade payroll experience that deepened client retention; for Gusto, the alliance validated its embedded API infrastructure and opened an unprecedented, low-cost commercial distribution channel into millions of American businesses, permanently securing its position as the premier financial utility of Main Street commerce.
