@johnvirality Medvi

[John @johnvirality]

this telehealth company hit $1.8B with 2 people by selling d*ck pills with fake AI UGC doctors:

the all-mighty MEDVI

it ended with an FDA class-a lawsuit, a New York Times front page, and platform bans across the board.

but hey their methods were pretty cracked

so today i’ll be breaking down the ENTIRE clinical avatar arbitrage playbook behind their $400M run rate

including the legitimate version that doesn't end with federal regulators involved...

here's what's inside:

> the authority psychology framework that explains why AI-generated doctors converted better than real ones in health advertising (the neurological mechanism that makes this work in every high-trust category, not just health)

> the three-step production system MEDVI used to generate synthetic medical presenters, localize them across demographics and languages, and manufacture social proof through sheer volume

> the exact line between legal AI spokesperson advertising and what MEDVI did to cross into fraud (most brands don't know where it is)

> the legitimate version of clinical avatar arbitrage: three proven approaches that extract the same trust mechanism without fabricating credentials

> the cross-category breakdown of how authority-based AI UGC applies to SaaS, DTC, finance, and professional services, not just health

all reverse-engineered from a real $400M case study with real regulatory consequences.

like + comment "MEDVI" and i'll send EVERYTHING your way

Paid coding courses make their creators rich. Not you.

so I built Open Vibe:
✦ free & open-source - not $299
✦ runs inside your agent - @claudeai, @opencode, etc
✦ the agent tutors as you build
✦ ends with a real SaaS via @opensaas_sh

I built Open SaaS, the #1 free SaaS starter on Github (14k★). Open Vibe is the prequel.

Most tutorials are boring.

So I built an interactive web dev course for Claude Code.

Claude is your tutor as you build real apps, providing animated diagrams, and explanations.

It's 100% free and open-source, too!

@TashiNakanishi With questionable strategies though :)

[Taalas Inc. @taalas_inc]

24 dedicated people.
$30M spent on development.
Extreme specialization, speed, and power efficiency.

Today we launch Taalas’ first product. Check it out:

My brother and I invented a new programming language for web development. It got trending on HackerNews and we raised $5M.

Five years later, I admit it was a mistake. A new, custom language is scary + IDE support is a real PITA.

Here’s the full story and what's coming next:

[Matija Sosic @MatijaSosic]

We’ve run 11 Launch Weeks at Wasp - probably more than anyone except @Supabase.

From the outside, it's all fancy tweets, memes and PH launches.

But here’s what it actually feels like to run 11 of them, and why its valuable even if only five people join:

[Matija Sosic @MatijaSosic]

We're deciding on prizes for our upcoming Design-AI-thon. We want to give out cool, well-designed pieces of hardware. Budget is $1000 for three prizes.

What shall we give away? Some of our ideas below:

[Matija Sosic @MatijaSosic]

This is why we're building https://t.co/6lGZ3Zxfhv - a new, truly full-stack framework.

Devs want Rails/Laravel experience for JS, but all the attempts so far have failed b/c either the timing was wrong, or the core team gave up (lost motivation, no money).

We've been pushing for almost five years and raised >$5M to have serious folks work FT on it. We're getting there, commit by commit.

[Vinny @hot_town]

paid SaaS templates are for suckers.

Open SaaS v2 is free, open‑source & way more badass:
✦ sexy ui - @shadcn
✦ payments integrated - @stripe @lemonsqueezy @polar_sh
✦ admin dashboard - @PlausibleHQ
✦ secure aws s3 file uploads - @awscloud
✦ full cursor rules & llms.txt - @cursor_ai

check out the @ProductHunt launch👇
