Proof
Social proof notifications and website personalization to boost conversions
About Proof
Proof is a social proof marketing platform that helps websites convert more visitors into customers by displaying real-time activity notifications. With two core products — Proof Pulse for social proof notifications and Proof Experiences for website personalization — the platform enables businesses to leverage psychological triggers like FOMO and social validation to increase signups, sales, and engagement. Proof Pulse displays three types of notifications: Recent Activity (showing individual user actions like "Mary from Austin just signed up"), Hot Streaks (aggregate counts like "47 people signed up in the last 24 hours"), and Live Visitor Count (real-time page viewers). The platform claims an average 10-15% conversion lift depending on notification type. Setup takes minutes — just paste a JavaScript snippet into your site header. Proof Experiences takes things further with full website personalization, allowing you to customize headlines, CTAs, images, and entire page sections based on visitor behavior, demographics, and firmographic data. With 60+ integrations via Zapier, Clearbit enrichment, and native connections to tools like Shopify, HubSpot, and Stripe, Proof fits into most marketing tech stacks. The company is a Y Combinator Winter 2018 graduate based in Austin, TX, serving over 25,000 businesses.
Pros & Cons

Cons
- Experiences (personalization) product starts at $599/mo — expensive for small businesses
- Pricing scales steeply with traffic volume; high-traffic sites pay significantly more
- Pulse visitor-based pricing means you pay more as your site grows, even if conversion rates plateau
