Avalara is a cloud-based tax compliance automation platform providing sales tax calculation, e-filing, and compliance management for businesses that need to calculate and remit sales tax accurately across thousands of US tax jurisdictions and international VAT/GST regimes.

The post-2018 South Dakota v. Wayfair Supreme Court ruling expanded economic nexus to require online sellers to collect sales tax in states where they exceed sales thresholds — dramatically expanding the number of businesses needing automated tax compliance. Avalara's Returns product files and remits sales tax with the appropriate taxing authorities.\n\nIn 2025, Avalara competes with Vertex (acquired by private equity), TaxJar (acquired by Stripe), and Thomson Reuters ONESOURCE Indirect Tax for sales tax and VAT compliance platform share. The tax compliance automation market has grown significantly as global e-commerce expansion and the South Dakota v. Wayfair ruling increased compliance obligations across all business sizes. Avalara's 2025 strategy focuses on expanding internationally (VAT compliance in Europe and GST in India and Australia), deepening integration with more ERP and e-commerce platforms, and adding AI-powered exemption certificate management and tax research capabilities.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
