The trouble announced itself at the office door. On a large New York construction project, Claire Wilson could see a subcontractor owner coming in hot, lock eyes with him, and know the subject before he spoke: the check had not arrived. The building might be rising. The trade partner had done the work. Somewhere between a contract, an owner's requirements, a payment application, and the general contractor's process, cash had stopped moving.
Wilson was then a project manager at AECOM Tishman, working in the world of Hudson Yards and JPMorgan's corporate headquarters. Those jobs offered the grand version of construction - logistics arranged across city blocks, teams coordinating thousands of decisions, a physical result that would redraw a skyline. Yet the recurring strain with trade contractors often came down to smaller objects: a form in the wrong format, a missing waiver, an approval living in somebody's inbox.
Years later, Wilson would call Siteline a "billing command center" for subcontractors. The phrase is compact, but it carries the whole journey. She went from coordinating pieces of megaprojects to organizing the administrative work that determines whether the companies actually building them can collect their money.
A professor reads the room
Wilson arrived at Bucknell University on the civil-engineering track. A professor noticed something useful about her before she had a title for it: she was highly social, she liked people, and she liked solving problems with them. He had trouble picturing her content in a structural-design role that might mean years at a computer. Project management would preserve the engineering challenge and add the human one.
Then two Bucknell alumni visited a class to talk about Tishman's work on the Freedom Tower. Wilson heard about the logistics of New York megaprojects and felt the decision click. "This is it," she later recalled. "This is exactly what I want to be doing." She graduated in 2015 with a BS in Civil Engineering and joined Tishman, first as an assistant project manager and later as a project manager.
The professor's advice became more than a career nudge. It identified Wilson's operating system. She likes complicated work most when it involves other people. That pattern runs through her second act, too: construction associations, customer conversations, conference rooms, and a software company whose value depends on translating one party's requirements into another party's payday.

The introduction that changed the jobsite
Wilson could imagine staying with the general contractor for her entire career. The startup turn was not an escape from construction. It began with an introduction. A friend connected her to Gloria Lin, a fintech product leader looking for an industry where the movement of money was ready for new infrastructure. Wilson knew one.
The match had a pleasing division of knowledge. Lin had worked at Apple and Stripe. Wilson knew how commercial projects behaved when plans met contracts, paperwork, and payment chains. They hit it off. Wilson saw a large problem and believed they had the right combination to address it. She moved to San Francisco, aware that it was risky but comforted by a practical thought: "Construction isn't going anywhere." If the company failed, the industry would still be there.
She joined Siteline in 2020 in construction solutions. The title changed as the company did: head of construction solutions, head of customers, interim CEO, chief operating officer, and eventually co-founder and CEO. Through those shifts, the job remained close to the trades. Public presentation materials chart the listening at more than 500 subcontractor interviews across over 35 states.
When the edge case is the business
A subcontractor rarely gets to announce one elegant billing process to every customer. The contract controls. One general contractor wants one portal and set of documents; another wants a different package. Project type, owner, state law, retainage, change orders, and position in the payment chain add their own rules. By May 2026, Wilson said Siteline held roughly 20,000 different client forms in its database.
This variety explains why software built for general contractors and repackaged for trades can miss the point. For a subcontractor, the exception is often Tuesday. Wilson's answer is not to ask customers to abandon the workflow overnight. It is to gather scattered spreadsheets and folders into one place, automate repeatable steps, and create guardrails around the deadlines that should not be missed.
The paperwork stack
The product ambition is therefore less about making an invoice prettier than making the status of a business legible. Which client pays slowest? Which office is bringing cash in fastest? Which project is approaching a lien deadline? What change order remains exposed? The better the answers, the fewer nights someone spends wondering whether a critical notice slipped through.
The company learns to divide the work
In March 2026, Wilson and Lin announced a leadership change they had planned together. Lin became president and returned her attention to product, engineering, and design. Wilson became CEO, responsible for scaling revenue and operations, deepening industry relationships, and making the customer experience tangible. It was a division built around demonstrated strengths rather than founder mythology.
Wilson had already spent years in the rooms where Siteline's abstractions become somebody's Wednesday afternoon. She wrote for construction finance audiences, spoke at national and regional events, served on the Bay Area Subcontractors Association board, and joined the American Subcontractors Association's national board in 2026. At CFMA's annual conference, she has said, Siteline colleagues compete for the chance to attend.
The reason is informational. A finance leader describing a messy closeout can teach a product team what a clean market report cannot. At an ASA Think Tank, Wilson watched a room of veterans discover from a peer that a bond could sometimes replace cash retainage. Their collective reaction - "Wait...you can do that?" - became the opening of an essay about the knowledge carried through professional communities.
The national board role also broadened her view of what software can and cannot carry. Mechanic's lien rules change from state to state, and preserving the right can depend on sending the correct notice by a precise deadline. Wilson has written about a contractor in the Washington, D.C. area who managed the paperwork carefully but still had little recourse after the general contractor failed and the owner had already paid. In California, the balance of rights can work differently. Product design can help a team follow the law in front of it. Advocacy can argue that the law itself should better protect the trade.
That distinction gives Wilson's association work a practical edge. Her public writing moves comfortably from calendar mechanics to Capitol Hill, but keeps returning to the same unit of consequence: a contractor that has already funded labor and materials while waiting for somebody farther up the chain. The policy vocabulary may be retention, prompt-payment rules, or lien rights. Inside the business, it becomes capacity. Money trapped in one project is money unavailable for the next payroll, crew, or bid.
“Every conversation, every piece of feedback, every hard question has made Siteline stronger.”Claire Wilson on becoming CEO, March 2026
From billing tool to operating judgment
Wilson's recent work pushes beyond faster paperwork. Siteline launched a lien-rights tracker built around state-specific laws and deadlines. She has discussed automated collections follow-up and a project snapshot that brings financial information together. The larger question is arriving earlier in the project: should a subcontractor take the job at all?
After meetings with lawmakers in Washington and sessions at CFMA Annual, Wilson wrote that smart subcontractors evaluate clients much as lenders evaluate borrowers. Payment history matters. So do change-order behavior and the time a customer keeps retention. A project that looks profitable on paper can consume cash for months. Growth without that context can make a busy company fragile.
Vertical software earns trust by learning the inconvenient details. Wilson's path suggests a practical sequence: live the workflow, listen across many versions of it, centralize what is scattered, and only then automate what repeats.
It is a fitting expansion for someone who started on jobs defined by sightlines. Siteline itself is a play on the architectural word: an unobstructed view between a person and the thing they need to see. Wilson now applies that idea to the cash behind commercial construction - not only where a bill stands, but whether a project, client, or deadline is quietly changing the health of a contractor's business.
The skyline still matters. It is why she entered the field. But her career turned on noticing the less photogenic structure beneath it: the agreements, documents, habits, and conversations that decide who finances the wait. Wilson's work is an attempt to shorten that distance, one form and one hard customer question at a time.
