About Kintsugi
Kintsugi applies AI to the parts of US sales tax that trip up growing businesses: watching in real time for where you've triggered nexus, categorizing products and SKUs for taxability, and calculating rooftop-level rates — then catching filing issues before they become compliance problems.
Founded in 2021, Kintsugi has raised over $30M across four rounds, including an $18M round in 2025 led by indirect-tax incumbent Vertex — a notable endorsement from the company it competes with.
AI drives real-time nexus monitoring, product/SKU tax categorization, rooftop-level rate calculation, and pre-filing issue detection.
Highlights
- Raised $30M+ including an $18M round led by Vertex (2025)
- Ranked among the top 10 sales tax compliance platforms on G2
- Aimed at SMB and mid-market e-commerce and SaaS sellers
