Kintsugi: Fueling Hypergrowth with Strategic Integrations

The Company

Kintsugi AI, Inc. is a San Francisco-based tax technology startup founded in 2022. Kintsugi takes the worry out of sales tax and lets you put your sales tax compliance on autopilot, delivering high performance, reliability, and flexibility as you scale. Its AI-powered platform delivers robust end-to-end sales tax automation without requiring businesses to build their own integrations. The platform is secure, encrypted, GDPR-compliant, and SOC 2 Type II certified. Jeff Gibson, Co-founder and CTO at Kintsugi, leads a rapidly scaling company with a clear mandate: to become the dominant player in the global sales tax compliance market.

The Challenge: Solving the 1,200 Integration Problem

As businesses expand across jurisdictions, tax compliance becomes increasingly complex - fraught with evolving rates, nexus rules, exemptions, and audit risks. Kintsugi’s vision requires tight integration with its customers' operational systems. Ranging from HRIS, Ecommerce, and Accounting platforms, Kintsugi quickly identified that truly serving the market meant supporting over 1,200 specific systems globally.This challenge created an immediate bottleneck, threatening Kintsugi's scaling momentum and time-to-market. Building and maintaining dozens of bespoke connectors would have diverted engineering focus from core innovation and slowed the company’s scaling momentum.

The Solution

Having successfully used Apideck in a previous venture, Kintsugi's leadership turned to Apideck’s Unified API platform to solve this core integration challenge. This partnership allowed Kintsugi to deploy live integrations with over 25 accounting and e-commerce platforms in a fraction of the time required for traditional development. By adopting the same technical foundation (Apideck’s architecture and recommended SDK provider, Speakeasy), Kintsugi’s engineers can now integrate new systems faster and focus solely on delivering tax logic.

Apideck’s unified APIs have enabled Kintsugi to implement integrations with dozens of platforms via a single interface. By automating tax workflows Kintsugi is powering real-time tax rate calculations and filings. Importantly, customers can trust that Kinstugi ensures regulatory compliance with built-in audit trails, exemption certificate management, and continuous nexus tracking.

The Results: Scaling with Precision and Speed

Kintsugi’s commitment to Apideck demonstrates a successful strategy for scaling a high-growth B2B SaaS platform:

• Rapid Expansion: Kintsugi was able to bypass the months of development typically needed per connector, enabling them to expand from core accounting solutions to a broad range of e-commerce systems.
• Engineering Focus: The engineering team shifted its focus away from maintaining fragile, vendor-specific connections toward enhancing Kintsugi's proprietary AI-driven tax automation features.
• Quantified Success: With 28 active connectors and high API usage, Apideck has helped Kintsugi reach the necessary breadth of customer coverage to deliver on their revenue expectations.

The partnership with Apideck ensures Kintsugi has the scalable, stable infrastructure needed to continue its ambitious global expansion and achieve its goal of dominating the entire sales tax compliance market.
