Kintsugi

About Kintsugi

Kintsugi's pricing page is the argument: $0 for the monitoring layer, then $75 per filing or registration, with no onboarding fee, no per-transaction charge and no long-term contract. The free tier is unusually load-bearing rather than a trial — global physical and economic nexus monitoring, comprehensive exposure and historical liability auditing, threshold alerts the moment you cross, AI product categorization, address validation, CSV imports, an in-app assistant called Kin, and no-code connectors for Shopify, Stripe, Chargebee and BigCommerce. A company can therefore quantify what it already owes before spending anything, which inverts the usual order of this purchase. Money starts only when Kintsugi acts on your behalf: registering you in a jurisdiction, filing a return, remitting. Starter adds automated registration, filing, remittance and deregistration where supported, refunds and amendments, basic exemption certificate management, a virtual mailbox for state notices, faster data sync and 24/7 live chat with same-day human responses. Premium is custom flat-rate pricing with volume discounts and holds the heavier scope: multi-country compliance across the US, Canada, EU, UK and 100+ countries, real-time calculation on invoices via QuickBooks, NetSuite and Dynamics 365, back filing with Voluntary Disclosure Agreement options, bulk exemption certificate management, API, SDK and SSO, and SLA-backed support. The company is young and unusually capital-efficient — roughly $3M of revenue in 2024 against a target of $10M for 2025, about 2,400 customers, and a valuation that went from $80M in November 2024 to $150M post-money by April 2025. That April round is the notable part: Vertex, the enterprise incumbent listed in this same category, put in $15M for a 10% stake plus IP sharing, a commercial arrangement and a board seat. The legacy engine vendor bought optionality on the startup undercutting it.

Notes

Three tiers, re-verified against the vendor pricing page on 2026-08-26. Free is $0 with no stated time limit and covers global physical and economic nexus monitoring, exposure and historical liability auditing, automated risk assessment, threshold alerts, AI product categorization, address validation and enrichment, the Kin in-app AI assistant, CSV transaction imports and no-code integrations (Shopify, Stripe, Chargebee, BigCommerce). Starter is $75 per filing or registration and adds automated registrations, filings and remittance, auto-register/auto-file/deregistration where supported, refunds and amendments, basic exemption certificate management, a virtual mailbox for state notices, faster data sync, onboarding assistance and 24/7 live chat. Premium is custom-quoted flat-rate pricing with volume-based discounts, adding multi-country compliance across the US, Canada, EU, UK and 100+ countries, real-time calculation on invoices via premium connectors (QuickBooks, NetSuite, Microsoft Dynamics 365), back filing with VDA options, advanced exemption certificate management with bulk upload and expiration notifications, ready-made and custom reports, API/SDK/SSO, dedicated onboarding and account teams with SLA-backed support, and the Kintsugi Guarantee. The vendor states no onboarding fees, no transaction fees and no long-term contract lock-in. Watch the unit: $75 is charged per filing or per registration, so cost scales with jurisdiction count and filing frequency rather than with revenue — model your own state count before comparing against per-state or per-market monthly subscriptions such as Anrok's or Sphere's.
