David Shijoon Bae and the six-week question

Six weeks is a long time to wait for someone to fix a dorm heater. It is enough time for an inconvenience to acquire a personality. David Shijoon Bae and his Harvard roommate, Michael Lin, put in a work request, waited, and eventually asked the technician why repairs and renovations took so long. The question carried them beyond their room. In 2026, the roommates became the co-founders of FlowManual, a company building software for construction’s paperwork.

A broken heater is a pleasingly unglamorous beginning for a technology company. There is no need to imagine a moment of revelation beside a whiteboard. Bae’s account begins with people wanting an ordinary job finished. The consequential move was asking about the delay, then continuing to ask people who worked in the industry. That makes the repair a useful opening to his story. To understand the person asking the question, though, it helps to leave the dorm and go back to California.

The writer before the engineer

At Orange County School of the Arts in Santa Ana, Bae studied in the creative writing conservatory. His early public record belongs as much to classrooms and creative projects as to technology. In 2024, he was an Irvine student, a first-generation immigrant, and a participant in school life who had started the WOW-Korea! Club. These details give his biography a particular setting: an arts school, an interest in language, and an effort to make room for other people.

There is a poem credited to Shijoon Bae, identified as a high-school junior, on the California Poet Laureate’s Orange County page. Its imagery moves through public transport, a jukebox, food and the Dodgers. A poem is no certificate of future entrepreneurial skill. It does, however, belong in this portrait. The construction founder had already spent time arranging words for purposes that had nothing to do with selling software. The career has an artistic chapter, and it deserves to keep its own shape.

FilmEnvisioned supplied a more practical outlet. Bae co-founded the organization and taught through it, with his project listing running from March 2022 to June 2025. It offered film and creative-writing programs for children in places with limited arts education. His description of the work includes a wonderfully compact verdict: “Made some great friends and funny films.” For all the language that tends to gather around leadership, friendship and a funny film make a respectable account of a productive afternoon.

A film needs more than a script

In October 2024, Bae and Timothy Okajima asked for help making a film called at our crossroads. They described themselves as Asian-American and immigrant high-school filmmakers. The fundraising appeal named two reference points, 500 Days of Summer and About Time, and described a story of young love encountering modern reality. It was a specific creative ambition, with recognizable influences and the unromantic requirements that accompany a camera.

The request covered equipment, lighting, filming permits, locations and actors. Those details make the project useful to a personal story: the young writer was also dealing with the arrangements that turn writing into something people can watch. A scene can be lovely on paper while remaining quite impossible to shoot until someone secures a venue. Film has a way of introducing artistic intention to logistics and letting logistics have the first word.

The appeal establishes a project the two wanted to make, rather than a finished film or a later award. What it shows is enough. Bae was working with a collaborator, describing an idea to an audience, and asking for the means to execute it. Before FlowManual’s product demonstrations, there was another attempt to explain what he hoped to build and why other people might want to help. The scale and subject would change considerably.

Getting students into the conversation

Bae’s public responsibilities also took him into education policy. He served as state president of the California Association of Student Councils for 2024-2025. His advocacy included English language learners and students from low-income backgrounds. In July 2024, he was among four Orange County students selected for Bank of America’s Student Leaders program, which connected participants with nonprofit work and a national leadership summit.

The record of his education work is unusually concrete. In November 2023, he was listed as the speaker for a financial-literacy proposal presented through the Student Advisory Board on Education. The proposal argued for more consistent attention to the subject in high school. Speaking for a student group requires a particular kind of translation: experiences from school have to become a request that an institution can consider.

A year later, the November 2024 student advisory material listed him as a speaker and co-writer on student representation. That proposal concerned students having formal opportunities to influence policy. There is a difference between being invited to describe a problem and being given a continuing route to affect it. The subject is a useful companion to his later founder story, because it asks how a system can hear the people who encounter it every day.

The room, the wait, the partnership

Harvard brought Bae into mechanical engineering and into a room shared with Lin. The company’s founding account identifies them as engineers and former Harvard students who left to build FlowManual. Their shared repair problem offered an introduction to construction, but a delayed service request could not, by itself, tell them what contractors needed. That required conversations with people doing the work.

The partnership now has defined responsibilities: Bae is CEO and Lin is CTO. Their company joined Y Combinator’s Summer 2026 batch. Bae reported that they began building on April 18 and raised $500,000 with Y Combinator a month later. His announcement also thanked people who had helped, ending with Harvard and his mother. A funding announcement has room for gratitude alongside the number.

The page that moves every other page

Bae’s demonstrations make his current work easier to understand than a broad promise about artificial intelligence. In one, he takes a set of six construction drawing pages and compares it with a revised set containing seven. A new fourth page changes the sequence. If software blindly compares pages by position, the sheets that follow can be paired incorrectly. A minor clerical change can make a comparison unexpectedly troublesome.

He demonstrates software recognizing the inserted page and matching the remaining sheets across revisions. Users can also pair sheets manually and give instructions for the comparison. The detail matters because construction documents arrive with revisions, reordered pages and shifts in scanned images. A tool intended for those documents has to contend with their actual condition.

This is a revealing example of the job he has chosen. It concerns a familiar annoyance with a precise mechanism, and a user who still needs to inspect the result. The person demonstrating it is explaining where a working process can go wrong. That gives the product discussion some welcome substance: a reader can follow the problem without accepting an industry-wide prediction.

The work that comes before the building

FlowManual focuses on estimating, bidding and purchasing for general contractors and mechanical, electrical and plumbing contractors. Its website describes quantity takeoffs, equipment counts, piping measurements and estimates built with a contractor’s own rates. These are parts of the preparation that precedes visible construction. Long before a finished building can attract admiration, someone has to count, price, compare and agree.

Bae’s August 2026 launch message emphasizes data security, straightforward onboarding and keeping teams in control. He reports savings of up to 30 minutes per hour on repetitive work. That is a founder’s performance claim; the useful point for this portrait is the way he frames the purpose. Professional judgment remains part of the process. Time saved on review is intended to give people more room for the decisions they are responsible for making.

The current website’s illustrative mechanical takeoff includes air handlers, pumps and diffusers, with quantities organized by item and drawing sheet. A sample estimate is a modest visual, but an apt one. It puts the conversation back into the language of the customer’s task. The software has to make sense when a person is working out a price, rather than only when someone is watching a launch video.

A career still being written

Bae has already gathered public recognition outside the company. The Congressional Award lists him among its 2024 Gold Medalists, and the Coca-Cola Scholars Foundation lists him as a semifinalist for its 2025 program. Those belong beside the arts work and student advocacy, rather than becoming ornaments attached to a founder title. They describe a period in which he took on several kinds of responsibility before choosing construction software.

His route has moved from creative writing to representation, engineering and entrepreneurship. It would be easy to give every earlier activity a convenient business explanation. The funny films can remain funny films. The student proposals can remain attempts to improve school life. The connections are interesting without requiring a childhood plan for a company that did not yet exist.

For now, the six-week wait supplies the story’s clearest hinge. Two roommates encountered a process they did not understand, asked someone inside it for an explanation, and kept asking. Bae’s earlier work gives that question a history. He had already practiced putting a concern into words and bringing it to other people. His current task is to make the answer useful to someone with a drawing set, a deadline and rather more paperwork than afternoon.
