“Can the workflow layer for subcontractor billing become the beachhead for construction fintech (payments, capital) on top of a $14B receivables base?”

The story

Siteline was founded in 2019 by ex-Stripe/Apple PM Gloria Lin and ex-Tishman project manager Claire Wilson to bring 'fintech to construction' — specifically for the underserved commercial subcontractor market. The company deliberately does NOT replace the accounting ERP; it sits on top as the pay-app / lien-waiver / A/R workflow layer and syncs to Sage / Viewpoint / QuickBooks / NetSuite. Public materials pitch Siteline as construction billing SaaS, not as an embedded-finance platform — there is no evidence of a payments, capital, banking, or card program. The 'financial foundation' narrative is aspirational; the current product is a workflow tool, not a money-mover.
