Starting with three close friends and a focus on building in public on LinkedIn, he grew to 400,000 users and $1.5M ARR in just 4 weeks, eventually selling to Wix for $80M+ without raising any external funding or even writing code for the last 3 months of the company's existence.

Chime Social

by Spencer Jones

Spencer Jones launched Chime Social in January 2024, a Twitter scheduling and analytics tool that grew to 70-80 customers doing ~$500 MRR in just four months. After 18 months of building a failed product, he committed to shipping faster and building for his own pain points as a power Twitter user.

Scale Hire

by Ravi Mettah, Victoria Young

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.

First customers: Friends and network from their previous roles at major tech companies (Tinder, Netflix, Uber, Facebook); early users were close contacts who participated in free pilot before paid conversion.

Astalti

by James Mooring

Astalti is a vertical SaaS platform built for NDIS (National Disability Insurance Scheme) service providers in Australia. Co-founded by James Mooring (developer) and Jono (NDIS provider with deep domain expertise), the company bootstrapped to $720K ARR in just 18 months by building exceptionally well-crafted software for a specific niche, focusing first on support coordination rather than trying to build a full CRM, and leveraging in-person events, word-of-mouth, and world-class customer support to drive growth. The combination of domain expertise, product excellence, and deliberate go-to-market choices created explosive word-of-mouth growth in a tight vertical with hundreds of thousands of potential customers.
