Each week, we spotlight an AI-driven app that solves real issues for B2B and Cloud companies. This week: Kintsugi, the next-gen AI agent for B2B tax compliance. The Hidden Challenge of Scaling A common yet overlooked hurdle in scaling B2B companies is sales tax compliance, which founders often ignore until it’s almost too late. Once you hit $100K revenue in Texas, you establish nexus—and then in California, New York, and more. This means tracking economic thresholds across 45+ states, each with unique rules, rates, and deadlines. Most founders do one of three things: - Ignore compliance until an audit letter arrives - Hire costly tax accountants, which remains largely manual - Stitch together error-prone spreadsheets None scale well, and penalties for mistakes accumulate quickly. Some companies face six-figure back-tax bills right before fundraising, hurting due diligence. What Kintsugi Offers Kintsugi is an AI-native sales tax automation platform tailored for fast-growing B2B and e-commerce businesses. Simply connect your billing system and Kintsugi handles the rest: - Nexus Monitoring: Tracks sales across 50 states (and 50+ countries), alerting you immediately when tax obligations arise—no more guesswork or spreadsheets. - Automatic Registration: Registers you in new states automatically upon hitting nexus, with one click. - AI-Powered Product Classification: Automatically classifies products and applies correct tax treatments, navigating complex variances like SaaS and digital goods taxation. - AutoFile: Calculates taxes owed, files returns, and remits payments monthly for every jurisdiction. - Real-Time Dashboards: Provides finance teams visibility of liabilities, exposures, and filing statuses everywhere. The Founder’s Approach Founded by Pujun Bhatnagar, ex-senior ML engineer at Meta, Kintsugi’s development began with 18 months of manual sales tax calculations for e-commerce and SaaS companies—before coding started.

This deep hands-on understanding shaped Kintsugi’s in-house AI classification and calculation engines, setting them apart from competitors relying on generic large language models, resulting in higher accuracy. Growth and Partnerships Since launching in August 2023, Kintsugi has: - Gained 2, 500+ customers - Achieved $10M+ ARR with only 0. 1% churn - Reached a $150M+ valuation - Formed a major partnership with Vertex in October 2025, integrating Vertex’s established enterprise tax engine with Kintsugi’s modern AI workflows, offering “enterprise accuracy with startup speed. ” Pricing That Supports Growth Kintsugi offers: - Free start with system connection and exposure insight; no credit card needed - $100 per filing pay-as-you-go model - Custom plans for high volume clients This contrasts with legacy providers charging over $5K just to begin, explaining Kintsugi’s rapid growth. Seamless Integrations and Easy Setup Kintsugi integrates effortlessly with tools B2B companies use daily, including Stripe, Chargebee, QuickBooks, Shopify, BigCommerce, Amazon, WooCommerce, plus an open API for others. Setup requires no coding, with most companies operational within a day. Ideal Users Kintsugi is designed for: - B2B and SaaS companies selling in multiple states, especially beyond $500K ARR when compliance complexity grows - E-commerce businesses with multi-state or international sales - Finance and RevOps teams weary of manual tax calculations - Founders delaying sales tax compliance but aware the bill is imminent If you’re a local single-state business, this may be excessive. But for national or global scaling, Kintsugi provides infrastructure that frees you to focus on growth over tax paperwork. Conclusion: Why Sales Tax Compliance Demands Attention—and How AI Helps Sales tax compliance is tedious and unglamorous, yet mistakes can cost heavily in penalties, audits, and lost deals. Kintsugi fills a critical gap by delivering AI-native automation for a problem many founders avoid. With over 1, 100 customers in just over a year, it’s clear this solution resonates. If sales tax compliance is on your “deal with later” list, beware—later tends to arrive faster than expected. 👉 trykintsugi. com
