Human insight platform for unmoderated video user research; 2M+ panelist access enabling same-day prototype and website testing for Apple and Salesforce competing with Maze and Hotjar.
UserTesting is a human insight platform providing on-demand access to targeted panelists who record their screen and voice while completing tasks on websites, apps, and prototypes — enabling product, UX, marketing, and research teams to watch real users navigate their products and hear authentic reactions within hours rather than weeks. Listed on NYSE (NYSE: USER) before being acquired by Thoma Bravo private equity in 2023 for approximately $1.3 billion, UserTesting is headquartered in San Francisco and serves thousands of companies including Apple, Salesforce, Microsoft, and Walmart for rapid user research.\n\nUserTesting's platform enables teams to recruit from a panel of over 2 million contributors globally, filtered by demographic characteristics, and have them complete structured tasks while recording their screen, voice, and facial expressions. Researchers receive video clips sorted by predefined test metrics within hours, rather than waiting weeks to schedule in-person usability studies. Machine learning tools analyze videos to identify emotional reactions, sentiment, and task completion rates across participants.\n\nIn 2025, UserTesting competes in the user research and experience insight market against Maze (prototype testing), Lookback (live user interview platform), Hotjar (behavioral analytics), and Medallia (enterprise experience management). The user research market has consolidated as companies invest in continuous discovery practices rather than periodic research sprints. UserTesting's acquisition by Thoma Bravo and combination with UserZoom (another Thoma Bravo portfolio company) created a more comprehensive research platform covering both unmoderated video testing and moderated live interview capabilities. The 2025 strategy focuses on the combined UserTesting-UserZoom platform, expanding AI-powered insight synthesis from video research, and growing enterprise adoption of continuous research practices.
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.
