One button that strips filler words, background noise, long silences and mouth clicks out of a podcast — $20K/month from a feature nobody wanted to build a company around
15,000 podcasters using it
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Be clear about what this entry is built on. Greg Isenberg spends an hour laying out a micro-SaaS playbook, and he uses CleanVoice as one of three worked examples of what a micro-SaaS actually looks like in the wild. The facts he gives about it are three sentences long: "clean voice 20k a month MRR... edit your podcast in 10 minutes automatically. So it's just the features around removing your background noise, filler words, long silence, mouth sounds, right? So 15,000 podcasters use it." That is everything the source contains about the business itself. There is no founder interview, no dashboard, no growth story, no stack rundown. What there is, in abundance, is the framework Isenberg wraps around it — and since he's presenting CleanVoice as an archetype of that framework, the framework is what makes this entry worth reading. His definition of a micro-SaaS: an extremely niche audience, a niche product that is "a feature of a feature," a focus on profitability rather than scale, and something a solo founder or tiny team can run. Typical margins 80-90%. A successful one gets you "10, 20, 30, 50k a month of profit." What he says makes CleanVoice fit the pattern is that it does one narrow, deeply annoying job for an audience that hits the problem on a recurring schedule. He names the pain personally: "I'm a podcaster and have a podcast, so I have felt this pain point." Our read: the interesting number isn't the $20K. It's the 15,000 users against $20K MRR, which implies most of those 15,000 aren't paying — a free tier or trial doing the work of a marketing channel. That's a very different business shape from the paid-only models elsewhere in this directory, and it only works because audio cleanup produces an obvious before/after in about ten minutes.

CleanVoice appears in Greg Isenberg's micro-SaaS masterclass as one of three worked examples, and the source contains exactly three facts about it: $20K/month MRR, 15,000 podcasters using it, and a description of the four cleanup features. Nobody from CleanVoice appears in the video, no dashboard or screenshot is described, no pricing is stated, and neither the founder count nor the stack nor the acquisition channels are mentioned anywhere. Isenberg has no stated relationship with the company. Everything in this entry beyond those three facts is either the general micro-SaaS framework he presents in the same video (funnel math of 10,000 visitors → 150 paying at $19, the 20% affiliate benchmark, the market gap heat map, the 80-90% margin claim) or our own analysis, and we have labelled which is which throughout. His 80-90% margin figure in particular is a generic micro-SaaS claim and is almost certainly wrong for a product that processes audio.
