“Can a shop-floor-informed vertical SaaS replace the paper/Excel/text-message stack of ICI trade subcontractors before a horizontal construction platform does?”
Appello is a Canadian vertical SaaS company founded in 2023 after two years of embedded field research inside Vanos Insulations, a mechanical insulation contractor in Ontario. It sells a modular workforce/operations platform (timesheets, scheduling, job costing, safety, progress billing) purpose-built for industrial-commercial-institutional (ICI) trade subcontractors. There is no embedded finance product: the only financial workflow is progress invoicing that syncs to QuickBooks Online, and payroll runs through QuickBooks Payroll — Appello does not itself move money, issue cards, lend, or hold funds.
Appello moves money over ACH.
Appello integrates with QuickBooks Online.
The Embedded Finance Index 2026 maps 2 layers in Appello's stack: Money movement (ACH); Accounting (QuickBooks Online).
Appello was founded by Corey Shelson and is founded in 2023, headquartered in London, Ontario, Canada (registered: Mount Brydges, ON).
Appello has raised undisclosed in total (latest round: Early Stage VC).
