Tiago Catarino: How Tiago Catarino Built Podsqueeze to $48,000/mo

Tiago Catarino is an indie entrepreneur from Lisbon, Portugal, who capitalized on the generative AI revolution with blistering execution speed. Alongside his technical co-founder Joao Aguiam, Tiago built Podsqueeze into a $576,000 annual recurring revenue ($48,000 monthly) AI audio repurposing powerhouse in under 18 months, with zero venture capital and a tiny team of three.

As an active podcaster himself, Tiago was intimately familiar with the post-production slog. After recording a 60-minute interview, podcast hosts spent four to six hours re-listening to audio, typing out show notes, writing chapter timestamps, drafting newsletter recaps, and creating social media quotes.

When OpenAI released Whisper in late 2022, Tiago and Joao realized that audio transcription had fundamentally crossed the accuracy threshold. Over a rapid two-week sprint, they built Podsqueeze to turn any audio file or RSS feed into a complete marketing kit with one click.

Here is the deep tactical story of how Tiago Catarino turned podcast post-production into a half-million-dollar bootstrapped SaaS.

The Venture Scorecard: Tiago Catarino’s Scaling Velocity

1. The Podcaster’s Dilemma: 4 Hours of Post-Production Hell

In late 2022, Tiago Catarino was hosting his own tech podcast in Portugal. While he loved recording conversations with entrepreneurs, he dreaded everything that came afterward:

• Listening back to transcribe key quotes manually.
• Formatting chapter timestamps for Spotify and Apple Podcasts.
• Drafting an engaging newsletter summary for his subscribers.
• Creating 10 promotional tweets and LinkedIn posts to distribute the episode.

This post-production grind took twice as long as recording the podcast itself. Most independent podcasters burned out after 10 episodes simply because the marketing workload was unsustainable.

In late 2022, OpenAI open-sourced Whisper, an automated speech recognition model with human-level accuracy.

Tiago called his friend and engineer Joao Aguiam:

“If we pipe an audio file through Whisper, and pass the raw transcript into GPT with carefully engineered prompts, we can generate timestamps, show notes, and social posts in 90 seconds. Let’s build it this week.”

2. The 14-Day MVP to #1 Product of the Day

Tiago and Joao avoided feature creep and focused exclusively on the core workflow:

1. User enters their podcast RSS feed URL or uploads an MP3 file.
2. The server downloads the audio and runs it through speech-to-text.
3. Custom GPT prompts parse the transcript into five specific outputs: Show Notes, Timestamp Chapters, Newsletter Summary, Tweet Thread, and Key Quotes.

Tiago recorded a raw 60-second video on Twitter demonstrating Podsqueeze analyzing a live podcast episode. The response from fellow creators was instantaneous: within 48 hours, over 500 podcasters had tested the tool.

In February 2023, they launched Podsqueeze on Product Hunt. The tool stormed to #1 Product of the Day, converting hundreds of free users into paid monthly subscribers and propelling the business to $4,000 MRR in its first 30 days.

3. The Power of RSS Automation & Negative Churn

The breakthrough that transformed Podsqueeze from a casual utility into a sticky, high-retention SaaS was Automated RSS Monitoring.

Instead of requiring creators to manually log into Podsqueeze and upload audio every week:

• Podcasters connected their public RSS feed (from Buzzsprout, Libsyn, Spotify, or Podbean) once.
• Whenever a new episode was published, Podsqueeze automatically detected the audio file, generated all marketing assets in the background, and emailed the finished bundle to the creator’s inbox before they even woke up.

                         Finished Marketing Bundle Emailed to Creator
                         (Zero manual uploads required)

This automated convenience made Podsqueeze indispensable. Even if a podcaster took a vacation, they kept their subscription active so their automated publishing pipeline remained uninterrupted.

4. Product Economics & Tiered Pricing Architecture

Tiago structured his pricing based on monthly audio consumption, aligning his revenue with the actual computational costs of transcription.

By keeping API processing costs under $2.50 per 100 minutes of audio, Podsqueeze maintained a gross profit margin exceeding 82%, allowing Tiago and Joao to reach $48,000 per month ($576K ARR) with just three remote team members.

5. Tiago Catarino’s Exact Tech Stack

Tiago and Joao designed an asynchronous microservice architecture to process gigabytes of heavy audio files reliably without locking up the user interface.

6. The 3 Tactical Rules for AI SaaS Builders

Rule 1: Build for Workflows, Not Just Model Wrappers

Anyone can call an API. The defensibility of an AI SaaS comes from deeply integrating into the customer’s existing workflow (like automatic RSS feed polling) so the user doesn’t even have to open your app to get value.

Rule 2: Charge Based on Cost Drivers (Usage-Aligned Subscriptions)

When your underlying costs are tied to API consumption (like audio minutes or image tokens), ensure your pricing tiers reflect those limits. A fixed-minute subscription model protects your margins from heavy power users while providing predictable recurring revenue.

Rule 3: Solve the Immediate Aftermath of Creation

Creators love creating; they hate distributing. Any software tool that eliminates the painful administrative chores that follow creative production (transcription, formatting, social repurposing) will find an eager, paying audience.
