Transistor.fm: Two founders built seven-figure ARR with $10K, no funding
In 2018, Jackson and Buda each put in $5K to start Transistor.fm; it grew to seven-figure ARR, never declining monthly, still unfunded.
Transistor.fm
What the business is
A podcast hosting and analytics platform for creators and businesses: upload audio, generate RSS feeds, publish to directories such as Apple Podcasts, and provide playback analytics; by 2024–2025 it hosted 30,000+ podcasts.
Starting capital：$10,000 (the two founders each contributed $5,000)
How it started
Jackson had run a failed sporting goods store and been $80,000 in debt, later entering the SaaS marketing world; he met engineer Jon Buda at the XOXO conference in 2014. In January 2018, the two each put in $5,000 to start building podcast hosting, and on the same day began recording the 'Build Your SaaS' podcast, publicly sharing all revenue figures from the first dollar. They launched publicly in August 2018, with first-month revenue of $33.
What happened
In the first month it reached #1 on Product Hunt for the day, with monthly revenue of $1,400; by the first anniversary of launch, monthly revenue was about $30,000, and the two founders went full-time. Around 2020–2021, ARR passed $1,000,000 while the team was still two people and unfunded; the founders later acknowledged stopping public MRR disclosures, but confirmed that growth became harder after seven-figure annual revenue and that there had never been a month-over-month revenue decline.
How it ended up
Still running: by the end of 2024, monthly recurring revenue was about $375K (a third-party estimate; the founders had stopped public disclosure), it hosted 30,000+ podcasts with a team of about 6–7 people, and it had been profitable every year since founding; Jackson described it as an example of a 'calm company'.
Background
Transistor.fm is a podcast hosting platform founded by Justin Jackson and Jon Buda in 2018: upload audio, generate RSS feeds, publish to directories such as Apple Podcasts, and provide playback analytics. The two each contributed $5,000 with no external funding, and when they launched publicly in August 2018 first-month revenue was only $33—a number they deliberately made public as the starting point of the story.
The bet was a 'calm company' rather than a growth machine: not chasing platform-style closed ecosystems, but betting that open RSS and subscription revenue could sustain a small company. From day one they publicly shared revenue, failures, and product decisions on the 'Build Your SaaS' podcast; in the first year after launch they reached #1 on Product Hunt for the day and grew monthly revenue to about $30,000, after which the two founders went full-time. Around 2020–2021 ARR passed seven figures while the team was still two people.
By 2024, Jackson personally stated that annual revenue had passed seven figures and that no month had seen a month-over-month revenue decline since launch; third-party estimates put end-of-2024 MRR at about $375K and hosted podcasts at 30,000+. The team remained only 6–7 people, profitable every year since founding, and still unfunded in 2025.
Jackson attributed this to two things: first, market selection—podcast hosting had high gross margins, RSS was still open at the time, and competition had not locked up distribution, making it '100 times easier' than the physical retail business he had failed at; second, using community trust as a customer acquisition channel, serving independent creators first, and even rejecting large enterprise customers that could harm team culture.
What has to be true
- Market selection precedes execution: Jackson's physical store experience showed software's high margins and open RSS made same effort yield different outcomes.
- Building in public is acquisition and accountability: disclosing numbers from $33 first month turned transparency into trust, bringing early customers.
- Restrained expansion: team stayed 6-7, rejected enterprise clients, measured health by profitability, resulting in eight years without revenue decline.
- Distribution before selling: Jackson and Buda's existing audiences meant no lack of listeners at launch; Product Hunt amplified reach.
What can be applied
Market choice matters: software has high margins and unlimited distribution vs. physical stores. Betting on open RSS and building in public turned transparency into trust, attracting first customers.
Aftermath
As of 2026-09-01: Transistor.fm remains operating and profitable, hosting 30,000+ podcasts with a team of about 7 people; the founders say the company has never had a month-over-month revenue decline. Jackson left Twitter/X in 2025 and publicly discussed vacation plans, and the company continues operating under the 'calm company' framework.
