At Party City, the balloons were the agreeable part. Jarah Euston remembers learning to use the helium tank as a teenager in Fresno. Less agreeable were the abandoned purchases that had to go back onto their proper shelves. Celebration, it turned out, required somebody to tidy up after it.
One evening after closing, she was stocking party favors beside a coworker a little older than herself. The coworker asked whether she had children. Euston was 16. She was startled by the question; her colleague was a young mother. What felt to Euston like a temporary stop on the way to college was someone else’s means of supporting a family.
That difference would stay with her. Today, she is the co-founder, president and chief operating officer of WorkWhile, a platform connecting hourly workers with businesses that need shifts filled. Her career has included finance, consulting, mobile analytics and data software. Yet her explanation for this company keeps circling back to people she knew before any of those jobs.
A good job is easy to describe in the abstract: decent pay, useful work, a schedule one can live with. The awkwardness arrives in the details. How many hours will there be? When will the money arrive? Can the worker choose a shift without surrendering the protections that make employment dependable? Euston has made those questions her business.

Fresno deserved something to do
Her route out of hourly work led through New York University and a sales-and-trading job on a bond desk at Bank of America. Finance did not appeal as a permanent destination. She returned to California and started an internet business, exchanging the institutional machinery of Wall Street for the rather smaller machinery of a local website.
Fresno Famous covered local entertainment and culture. Modesto Famous followed. In December 2006, McClatchy bought the sites. Before she was selling a labor platform, Euston had found a business in helping people discover what was happening around them. A town is easier to enjoy when somebody bothers to tell you where to go.
The work also pulled her into civic life. After Fresno Famous began covering the arts scene, the mayor invited her to join the city’s Creative Economy Council. Euston joked that he probably hoped to discourage her from writing about him. She wrote about the council’s meetings anyway, giving readers another route into the discussion.
Selling a community website brought a different worry: would readers still feel it belonged to them once a newspaper company owned it? Euston defended the continuity of the sites, down to their code and editorial format. Ownership could change in a transaction; a community’s willingness to stick around had to be earned.
A career with several return tickets
After selling the business, she earned her MBA at Wharton, graduating in 2009. The timing put her into a recession-era job market. She joined Boston Consulting Group, then returned to a smaller company, Flurry, where she led analytics and marketing. Yahoo acquired Flurry, bringing another transition from startup to a larger organization.
There was substance beneath the job changes. At a San Francisco analytics symposium in 2012, she presented on the spread of mobile apps, including how people used their phones during the Super Bowl. Understanding behavior at scale became part of her professional toolkit. Even a football broadcast could be studied through the devices competing for its audience’s attention.
She later co-founded Nexla, a data-operations company founded in 2016. Its work concerned moving and transforming data between systems. The subject seems distant from a Fresno events website, but both required making scattered information usable. At Nexla, she served as a co-founder and vice president, helping explain and commercialize the product.
The sequence is less tidy than a biography arranged around one inevitable calling. Euston has described alternating between large and small companies as a practical response to opportunity, acquisitions and the appeal of stability. Seen that way, a career can have several return tickets. Each stop need not pretend to be the final destination.

Before the pitch, take a shift
WorkWhile was co-founded with Amol Jain in 2019. In December 2020, they announced its launch and a $3.5 million seed round led by Khosla Ventures. The early proposition paired workers with shifts suited to their skills, schedules and location. Employers paid for access to a screened workforce; workers could find jobs through an app.
Wharton’s 2021 account described the range: full-time positions, temporary jobs and last-minute shifts, accompanied by features such as next-day pay and flexible scheduling. That combination mattered. Getting matched to a job and getting paid for it are separate events, and the time between them can be expensive for someone with little room in the household budget.
Euston had also spent days working in a warehouse before raising money. Investors found the preparation impressive. She considered it an obvious piece of homework. Her advice to prospective founders placed research and user interviews before fundraising. The right to talk confidently about a problem, in this account, begins with spending time around it.
Her early work history supplied its own cautionary material. After Party City came Kenny Rogers Roasters. She has recalled arriving at a workplace to find it boarded up, alongside the uncertainty of changing schedules and insufficient hours. WorkWhile’s ambition grew out of that experience: give people more usable choices about earning a living.
“Start now.”

Who gets an introduction?
Euston has also worked on the question of who gets access to the people holding the checkbooks. In 2018, she and Alice Zhang attended a San Francisco angel-investment conference and noticed how few women were represented. The scene prompted questions about whether the imbalance extended through their own university network.
They helped create the Wharton Alumnae Founders & Funders Association, or WAFFA, to connect women with investors, resources and one another. The organization now lists Euston as a co-founder on its board. Her involvement gives another dimension to her career: she has helped build a network as well as companies.
She has invested herself. Sounding Board named her among its angel investors, and her endorsement drew on experience as both an investor and a customer of coaching. It is a useful reminder that entrepreneurship includes asking for guidance. People can run a business and still benefit from someone else asking better questions.
The promise meets the rulebook
WorkWhile’s worker-first ambition has faced a substantial test in California. In December 2024, a court-approved agreement required the company to pay $1 million in restitution to non-delivery workers and treat its California non-driving workers as employees. The dispute concerned whether workers had been classified as independent contractors when they should have received employee protections.
A further $4.5 million settlement announced in January 2026 addressed delivery-driver claims for an earlier period. WorkWhile continued to deny the allegations. The settlement document also records that Euston had been dismissed from the action and was no longer a party. Those distinctions matter: a company’s settlement, its denial and a founder’s individual status are separate facts.
For the business she helped create, the tension is central. An app can offer convenient access to shifts while the employment relationship still carries obligations. A worker’s freedom to choose hours and a company’s responsibility for wages must both survive contact with the actual arrangement. Flexibility is a feature people can value; classification determines enforceable rights.
The experience makes a demanding yardstick for the mission Euston describes. Success needs to be visible in the terms of work as well as the ease of finding it. A reassuring interface is welcome. So is an arrangement that holds up when someone asks who owes whom what at the end of the shift.
A different chair, the same company
In June 2025, WorkWhile announced a $23 million Series B led by Rethink Impact. Simon Khalaf, already a board member, became COO. He and Euston had worked together since he hired her at Flurry in 2012. The relationship connected an earlier chapter of her career to the company’s next stage.
By February 2026, they were changing chairs again. Khalaf became CEO; Euston became president and COO, continuing to lead go-to-market and operations teams. In announcing the transition, she reported more than 1.2 million workers on the platform. That is a company-reported platform figure, rather than a count of people working a shift at any one moment.
The company also introduced real-time pay, extending its attention from matching people to shifts toward when earnings become available. Inc. included Euston in its 2026 Female Founders 500, recognizing the workforce-management platform and the introduction of faster access to pay. These are developments with consequences measured in ordinary household timing: a completed shift, a bill due, money available.
Her public conversations continue, including a January 2026 appearance on The Rethinking Work Show about hourly work, behavioral data and community. Across those subjects runs a recurring practical concern: what happens when a system meets the person expected to use it?
Euston’s career has moved through a party store, a bond desk, a local publishing venture and several technology companies. The distance between them gives her story its interest. At WorkWhile, she is responsible for making a broad promise function in particulars. Somebody needs a shift. Somebody needs a worker. The schedule, the pay and the obligations all have to add up.
