Building https://t.co/pAdKDgK59w and https://t.co/2flHjGjomR to $1m ARR

Joined June 2022
Skype shut down in May. Teams doesn't support normal calling. But I still needed to call my PatientNotes customers in the US & Germany. Problem: I'm in Dubai. International roaming would bankrupt me 💸 So I built BubblyPhone in a weekend 🫧📞 ✅ Browser-based (no app needed)

6 months ago I had 500 LinkedIn followers. Today: 22,000. I stopped talking about myself and started solving problems for others. Now LinkedIn drives most of my revenue. If you want to grow: give value first, sell second, post consistently. That's it.

Built a "Report a Bug" button for BubblyPhone. First bug report came in today: "I can't make calls to my contacts!" Investigated for 10 minutes. The "bug": she imported contacts without country codes. The fix: now the app automatically detects missing country codes and asks

Claude Code just asked me if I want to add an optional profile setup step after signup. I completely forgot about this. Plan mode now suggests features you might have missed. This is insane.

Being a solo founder sounds romantic until you’re deep in the day-to-day. Talking to customers is the most energy-draining part by far. Not because they’re wrong, but because every platform demands a different mental mode. PatientNotes: doctors in the US and Germany. Many are

This is why insider trading rules exist in public markets. Not to protect feelings, but to protect market credibility. Without trust in fair information, prediction markets turn into casinos with insiders.
I might have just found an OpenAI employee’s wallet on Polymarket User 'pony-pony' is up $80,000+ betting on internal company timelines that nobody else could possibly know Look at the precision: - GPT 5. Knew it wouldn't be released by Aug 5, but was guaranteed by Aug 10. And

Added BubblyPhone to @trust_mrr . Its not a SaaS yet, its pay-as-you go. But will soon add a new feature, where users can purchase their own phone numbers + receive calls + receive txt messages. That's actually a huge problem, where Startups need to list their Support Number

Shipped a bunch of updates to BubblyPhone lately and realized something obvious in hindsight 😅 Users don’t automatically know what changed. So I added a “What’s New” feed with full timelogged updates inside the app. Recent drops: • Account settings + invoices • Google users

Love shipping on weekends. Got some user feedback for bubblyphone - when a call is happening the dial disappears --> and when an automated service occurs, people are unable to press any buttons and are stuck. Need to fix it asap

Rebuilding the entire frontend for PatientNotes with Opus 4.5 feels incredible. Nothing seems impossible anymore.

The moment my marketplace started working: I stopped asking "how do I get both sides?" And started asking "which side can I make so valuable they'll wait for the other?" Built a free AI-powered candidate database. 6,000 people joined. Employers came running. Solve one side

The conversion on bubblyphone is insane. Everytime somebody registers via google, they convert and top up between $5 and $20. Need to do more marketing.

Marketplace economics are brutal: - Acquire supply (costs money) - Acquire demand (costs money) - If supply churns, demand churns - If demand churns, supply churns - You're basically funding two failing startups at once SaaS economics: - Acquire customer - Keep customer Pick
