Fabrizio Rinaldi and Francesco Di Lorenzo are two Italians who found each other on Twitter in 2011, bonding over tech and design. Fabrizio was a designer and filmmaker. Francesco was a software engineer who had worked as iOS engineer #30 at Bending Spoons. They met in person, clicked, and started collaborating.
Their first project together was Boxy, a minimal Gmail client for Mac, back in 2015. Then they built Mailbrew, an email digest app that consolidated feeds from various apps into a daily newsletter. It worked, but it wasn't growing fast enough to be their main thing.
In late 2020, Fabrizio wanted a simple tool to write Twitter threads. Nothing fancy. Just a clean writing experience with a preview of how the thread would look. He started building one as a side project. They launched Typefully in December 2020. Launch day: 16,000 page visits, 1,432 signups, $155 in revenue.
Then the product made $0 for five months. They kept the whole thing free while they figured out what Pro features people would actually pay for. In May 2021, still at zero MRR, they introduced a Pro plan iteratively, letting early users lock a discounted price to support development. They slowly released Pro features over many months instead of building a full paid tier in isolation.
The turning point came when Twitter co-founder Evan Williams invested in Typefully in October 2022. Not a huge round, but the credibility was enormous. In January 2023, they sold Mailbrew entirely, freeing themselves to go 100% on Typefully. This focus paid off. MRR climbed from $9K in early 2022 to $113K by late 2024.
The growth engine is almost entirely word of mouth. Typefully's shared draft feature naturally leads users to invite collaborators. The collaboration workflow for teams creates organic expansion. When someone shares a draft with a colleague, that colleague discovers Typefully. No ads, no sales team. Francesco posted that growth past $1M ARR was "almost 100% word of mouth from users recommending the product."
Here's how @typefully continues to grow past $1M ARR. Spoiler: it's almost 100% word of mouth from users recommending the product.
Today, Typefully serves 220,000+ creators across Twitter, LinkedIn, Threads, Mastodon, and Bluesky. Two people generate $1.4M+ ARR. The tech stack is Next.js, React, TypeScript, and Tailwind CSS, hosted on Vercel. They expanded from a simple thread writer into a full creator platform with analytics, scheduling, and team collaboration. The product that made $0 for its first five months now makes more per month than most VC-backed startups.
