Kintsugi is an AI-enabled sales tax compliance platform that automates tax calculations and filings and integrates with Shopify, Stripe, Chargebee, QuickBooks, or custom APIs. The product offers free tax liability calculations, charges for tax filing, and provides an auto-remit option to file taxes automatically after ingesting revenue data. The company aims to support compliance across 171 countries and plans expansion into South America, Africa, India, and China. Founded in 2023 and based in San Francisco, Kintsugi targets small and medium businesses as well as larger customers. Kintsugi generated $3 million in annual revenue last year, reports profit margins above 93%, and targets over $10 million in revenue by the end of 2025. The startup serves 2,400 customers (45% SaaS), processes 5.5 million transactions valued at $7.7 billion, employs 95 people, and reports a 0.1% churn rate. Kintsugi automates sales tax compliance by connecting to companies’ billing and payment systems to determine state liabilities, register businesses in the correct jurisdictions, calculate taxes, and remit payments. The company uses in‑house AI models with humans in the loop, which the CEO says produces more accurate results than competitors relying on large language models. Founded in 2022 and based in San Francisco, Kintsugi launched its website in August 2023 and has grown to more than 1,100 users in the past year. The company has earned $1 million in revenue and offers a freemium approach: free, regularly updated analyses, $100 per tax filing, or custom plans. Competitors include Anrok, CereTax, and legacy outsourcing providers, but Kintsugi emphasizes easier onboarding and free ongoing reports as differentiators. Kintsugi plans to use new capital to expand its technology and to prepare for expansion into Canada and Europe. Kintsugi AI offers an end-to-end sales tax automation platform that handles real-time nexus monitoring, AI-enabled product categorization, rooftop-level tax calculation and validation, sales tax registration, filing, exemption certificate handling, and back-tax compliance. The platform is secure and encrypted, GDPR-compliant, and SOC 2 Type II compliant, aligning with the Trust Services Criteria for security, availability, processing integrity, confidentiality, and privacy. The company was co-founded by Pujun Bhatnagar, Barkin Doganay, and Jeff Gibson. Kintsugi intends to use the Series A proceeds to further develop its sales tax management solution. Financially, the company completed a $6M Series A at a $40M valuation. The product targets automation of sales tax compliance workflows for businesses.
