Scale Hire is a SaaS platform that democratizes access to professional executive coaching by pairing members with coaches through structured guided sprints. After launching a free text-based coaching MVP that showed promise but poor monetization, founders Ravi Mettah (ex-Tinder) and Victoria Young pivoted to a cohort-based course model with weekly content, exercises, and one-on-one coaching feedback, achieving stronger retention and product-market fit. The platform now operates as a three-sided marketplace connecting members seeking career advancement, program creators building curricula, and coaches offering guidance.

Trends.vc is a newsletter and community platform founded by Drew Riley that provides deep-dive analysis of markets and trends for entrepreneurs.

Birch built Bebo by reapplying lessons from his previous viral success with Birthday Alarm, focusing on inherent virality through address book imports and photo sharing.

Amber is a Bitcoin dollar-cost averaging app launched by Alex Svetski ('Angry Alex'), a serial entrepreneur and Bitcoin advocate. The app allows users to passively accumulate Bitcoin starting from as little as $5/day through spare change rounding or recurring buys, with Bitcoin stored in cold storage.

Sean built an ascending-clock second-price auction platform to resolve disputes over valuable new top-level domains (.app, .blog, .church, etc.) worth hundreds of millions. After 8 months of grueling direct outreach to reluctant tech giants, he convinced Google and other major companies to use the platform, which has since facilitated auctions exceeding $100 million per domain. The business model charges 4% commission on auction proceeds.

Zola Electric delivers electricity to a million people in Africa daily through solar and battery systems designed for unreliable or absent grid infrastructure.

By working backwards from customer price points and substitute spending on kerosene and phone charging services, Zola built an accessible solar solution and has since raised over $100 million in equity funding to scale across Africa.
