Kintsugi automates sales tax compliance using Python + FastAPI on AWS Lambda, with native integrations into Shopify, Stripe, QuickBooks, and Xero. The stack reveals a serverless-first, API-heavy approach optimized for rapid compliance workflows rather than traditional enterprise software. Active projects center on tax logic documentation and n8n-based automation pipelines, while hiring remains light (5 open roles, mostly engineering and research) — typical of an early-stage fintech startup stabilizing its core automation engine before scaling go-to-market.

About Kintsugi

Kintsugi automates sales tax compliance for e-commerce and SaaS companies globally, founded in 2022 and based in San Francisco. The product bridges two operational modes: fully automated compliance for companies wanting hands-off tax handling, and white-glove support for those requiring custom tax treatment. The platform integrates with major payment processors (Stripe, Shopify), accounting systems (QuickBooks, Xero), and billing platforms (Chargebee, BigCommerce). Current work includes scaling serverless integrations, building sales motion for SMB and mid-market segments, and expanding the sales team to drive ARR growth.
