The most revealing product in William Giuliani's career begins with a familiar domestic fiction: that this weekend, surely, there will be time. Time for a project with the children. Time for a real conversation. Time to make a memory worth keeping. Then the grocery list lengthens, a message arrives, and Sunday evening quietly collects another abandoned intention.
Giuliani, a Denver engineer and father of two, helped turn that little failure of scheduling into a software problem. Kidiosity, the company he co-founded with Andy Zurcher in 2020, gives parents activities to do with their children, prompts conversations, lets them put an idea on the calendar and offers a place to preserve the result. It is technology trying to usher a family away from technology, a phone app whose most successful session may end with the phone put down.
There is a pleasing contradiction in that. Giuliani's public founder biography says he likes the latest gadgets. It also says he can karaoke every Daniel Tiger song ever written. Somewhere between those details sits the practical character of his work: serious technical experience, applied to lives that are already noisy enough.
The recurring product in Giuliani's career is not an app. It is a little room in somebody else's day.Banking, cycling, parenting and field service share one scarce resource
The customer is already moving
Giuliani describes himself as an engineering leader with 20 years of experience scaling products and teams. The chronology begins close to the machinery. His early work included Java and mobile application development, followed by user-interface work at HomeAdvisor. He later held senior mobile developer roles at HumanCode, My Dobot and Remotely. The job titles matter because they place him in the era when mobile stopped being a smaller version of the web and became the place where ordinary work happened.
His formal training fits that bridge between systems and customers. Giuliani studied Computer Information Systems at Western Michigan University's Haworth College of Business from 2003 to 2005, earning a bachelor's degree, and also studied at Maastricht University. Computer information systems is a wonderfully literal name for a discipline: it lives where code meets an organization and where a technical choice eventually lands on somebody's desk, statement or schedule. His later career would keep returning to precisely that junction.
That shift changes the temperament of product design. A person standing beside a service van, watching a training interval or managing a child does not have the patience of someone settled behind a desk. The interface must know what matters now. It must forgive a thumb, survive an interruption and remember where the user was. Elegance becomes less about ornament and more about reducing the number of decisions between intention and action.
From June 2018 to August 2020, Giuliani served as a Director of Engineering at Fifth Third Bank. Banking software carries a different sort of pressure. A missed tap is annoying; a misplaced decimal is an event. The public record is spare on individual projects, so grand conclusions would be decoration. What can be said is that the role marked a move from building mobile products to leading the teams and systems behind them.
A side project with a bedtime soundtrack
Kidiosity is the chapter that makes the rest of Giuliani's career easier to read. The company calls itself created by parents, for parents. Its founding premise was not that families lacked ideas. The internet has never suffered an idea shortage. The problem was the distance between saving an idea and actually doing it.
The product therefore combined discovery with commitment. Parents could find an age-appropriate activity, follow plain instructions, assign it to a particular day and receive a reminder. Daily conversation starters offered another small bridge. A Memory Book let families save a picture and a note after the thing had happened. This was not merely a library of craft projects. It was a modest piece of behavioral architecture, one that understood the calendar as the border between aspiration and experience.
The first iOS release listed by Apple arrived on December 29, 2020, in the peculiar holiday week when family togetherness and parental fatigue are equally available. Early updates simplified registration and added a feed of parenting insights and inspiration. The app promised weekly activities, daily prompts and a record of family moments. Its materials were explicit about the opponent: not bad parenting, but overloaded schedules and endless demands.
Giuliani's role in that story is both technical and personal. He brought more than 15 years of experience launching and scaling technology products, while the problem came from the household. His co-founder was also a parent. Their advisers brought backgrounds in early childhood relationships and family development. The result was a product team built around a use case that could not be dismissed as a persona on a whiteboard. Its intended users were people they knew because they were those people.
Training plans and the discipline of enough
After banking, Giuliani led engineering at FasCat Coaching, where his team developed Optimize, a mobile app for cyclists. The surface details changed from children and conversation cards to training, recovery and performance. The underlying demand did not. An athlete has limited hours, uneven energy and a plan that must survive weather, work and the occasional revolt of the legs.
Coaching software is another argument against information for its own sake. A cyclist can collect more numbers than a Victorian railway office. The useful product is the one that turns those numbers into the next sensible action. It must respect ambition without confusing more effort with better judgment. Even the name Optimize suggests a finite system: not everything at maximum, but the right work at the right time.
Seen beside Kidiosity, the move is less eccentric than it first appears. Both products sit between a plan and a person. Both must make expert thinking feel usable. Both succeed when the user closes the app and goes to do something in the physical world.

The office inside the service van
In 2023, Giuliani joined Housecall Pro as Senior Director of Engineering. The Denver company makes an operating platform for home-service businesses. Its users include plumbers, electricians, HVAC technicians, cleaners and other professionals whose workplace changes address several times a day.
Their software problems are gloriously untheoretical. A job must be booked. A technician must know where to go. A customer wants an arrival time. An estimate needs approval; an invoice needs payment; a review request needs tact. Housecall Pro puts scheduling, dispatch, customer communication, invoicing, payments and reporting into one system. The company says its platform serves more than 45,000 businesses and 180,000 service professionals.
For an engineering leader, this is not one product problem but a neighborhood of them. The calendar talks to the customer record. The invoice talks to the payment system. The mobile app talks to the worker in the field. Reliability is visible because the business itself is happening through the software. When the system saves a few minutes, those minutes do not become an abstract efficiency ratio. They can become another job completed before dinner.

A career measured in returned minutes
Giuliani's public footprint is restrained. There is no great library of keynote declarations, no manifesto polished into personal doctrine. What exists instead is a sequence of products and roles. It shows a developer becoming a mobile specialist, a specialist becoming a director, a director becoming a founder and an engineering leader carrying that range into a large software platform.
It also shows an appetite for different kinds of users. The bank customer wants trust. The cyclist wants judgment. The parent wants presence. The service professional wants the day to hold together. These are not interchangeable needs, but each requires software to behave like a considerate guest: arrive prepared, do the useful thing and avoid taking over the room.
The playful note about Daniel Tiger belongs here. It prevents an engineering career from flattening into architecture diagrams and promotions. Products are built among songs, school schedules, workouts, invoices and all the other unruly material of a life. Giuliani's work has repeatedly met people in that material rather than asking them to step outside it.
Software cannot manufacture time. The clock remains offensively consistent. But a well-made system can return a sliver of the day that paperwork, indecision or searching would have consumed. Enough slivers, arranged carefully, begin to look like an afternoon. Perhaps even a song.
