Business Model
What each company does and how it makes money
PDF Solutions provides proprietary software and hardware solutions for semiconductor design and manufacturing optimization. It generates revenue through software subscriptions—primarily its Exensio analytics platform—and sales of physical intellectual property products like characterization vehicles and test chips, with professional services contributing additional income. The company's moat lies in its deep integration across the semiconductor value chain—from design to manufacturing—and its proprietary data analytics that help chipmakers improve yield and reduce costs.
Shopify is a comprehensive commerce platform that enables businesses of all sizes to create online stores, manage sales across multiple channels, and handle operations like payments, shipping, and inventory. It generates revenue primarily through subscription fees for its platform tiers — which account for about 30% of revenue — and merchant solutions like payment processing, shipping, and capital advances that make up the remaining 70%. The company's key advantage is its integrated ecosystem that combines easy-to-use store creation tools with a vast app marketplace and fulfillment network, creating high switching costs for merchants as they grow their businesses.
