Pomegra
Toronto's Polygrade left stealth with $6.3M in seed funding to automate home-warranty claims with AI agents. Construct Capital led the second tranche. Valuation is undisclosed.
Key Takeaways
- Polygrade raised $6.3M USD (about $9M CAD) in seed funding, structured as SAFEs.
- Construct Capital put in $3M in July 2026; five investors backed an earlier $3.3M tranche in early 2025.
- Two of the five largest US warranty firms are customers, and the team numbers seven.
Lead
Polygrade, a Toronto software startup, emerged from stealth on October 6, 2026 with $6.3M USD in previously unannounced seed funding. The company sells agentic AI software that handles home-warranty claims for warranty companies, parts suppliers and service providers in the United States. Co-founders David Steckel (CEO), Eui Chung (CTO) and Kaustubh Vongole (head of product) started the company about 18 months ago as ProPay, a tool to help contractors get paid faster. It has since been renamed to cover the whole claim.
How Is the $6.3M Seed Round Structured?
The round is two tranches of simple agreements for future equity (SAFEs), not a priced equity round. The first, $3.3M, came in early 2025 from American Family Ventures, Nine Four Ventures, Hustle Fund, Room and Pillar. Construct Capital added $3M in July 2026 and is the lead investor in that second tranche.
Because SAFEs convert into equity at a later priced round, no valuation has been disclosed, and none is implied. The 18-month gap between tranches suggests the company raised a small amount, built a product and customer base, and then took a larger check once there was usage to show. All backers are US-based, which fits a company whose entire initial market is American.
What Does Polygrade's Software Do?
Polygrade's platform replaces manual claims handling with specialized AI agents at five stages: first notice of loss, pre-dispatch triage, authorization, parts procurement and contractor payment. Each warranty company sets the policies, thresholds and rules the agents work within, and exceptions go to human staff.
That differs from the incumbent approach. Existing claims systems record information, route tickets and track status, while people still do the deciding and chasing. Polygrade is pitching software that does the work itself. It says it can run on top of a warranty company's current systems, so customers do not need to replace them.
Who Is Using It?
The company says two of the top five US warranty firms are customers. Named warranty customers include Fidelity National Home Warranty and Cinch Home Services. Parts and supply partners include Encompass, UED, Sibi and Marcone. Fidelity National's Jason Manns said the platform improved the claim experience and lowered costs without a system replacement.
Revenue, claim volumes and cost savings have not been disclosed. Customer names and an endorsement are a better signal than a demo, but they are not a substitute for contract values or retention figures. Those will matter at the next priced round.
Why Is Warranty Claims Handling a Target for AI Agents?
Warranty claims are rule-heavy, repetitive and spread across several parties: the homeowner, the warranty company, the contractor and the parts supplier. That structure suits software that can follow written policies and escalate exceptions. Steckel has said no global leader yet addresses the warranty-specific case.
The founders have relevant history. Steckel founded Setter, a home-services startup acquired by Thumbtack, and later served as chief product officer of Sears Home Services. Construct Capital's Rachel Holt said Polygrade could become the "intelligence and execution layer" for a large category. That is an investor's framing and should be read as one.
What Comes Next for Polygrade?
The company plans to spend the money on forward-deployed engineering, go-to-market and partner enablement, with headcount now at seven. It operates from Toronto, with additional offices in St. George, Utah, and Austin, Texas. A Canadian launch is planned only after the US business is established.
The longer plan extends past home warranties into extended warranties, OEM warranties and equipment breakdown insurance. Each adds its own regulatory and underwriting rules, so expansion will test whether the agents generalize or whether each line needs separate tuning. Competition from established claims-management vendors adding their own AI features is the obvious risk.
Outlook
Polygrade has $6.3M, two large warranty customers and a team of seven, with valuation and revenue undisclosed. The next milestones are a priced round that converts the SAFEs and evidence that agent-run claims cut cost without raising denial disputes. Moves into adjacent warranty lines and Canada will follow only if the home-warranty product holds up at scale.
