Hims & Hers Raises $1 Billion to Build AI-Powered Healthcare Platform
Hims & Hers just raised up to $1 billion through convertible notes to fund AI expansion and acquisitions. The telehealth company hired Mo Elshanawi as CTO from autonomous driving company Cruise. CEO Andrew Dudum says he picked someone from self-driving cars because "safety is paramount in that business" and that mindset fits healthcare.
The AI strategy focuses on:
- End-to-end patient experience from intake to treatment
- Personalized workout and nutrition plans alongside prescriptions
- Custom AI servers for HIPAA compliance instead of using ChatGPT
- Global expansion of their technology platform
Hims & Hers wants to become the "Netflix of healthcare" by aggregating demand. This forces suppliers like Novo Nordisk to work with them to reach customers. The company needs to scale fast before competitors catch up, similar to Uber's strategy in ride-sharing.
What Web Browsing Data Tells Us About How AI Appears Online - Pew Research
Pew Research tracked Americans' web browsing and found something surprising. Nearly everyone encounters AI content online, but most don't realize it. People see AI-generated search summaries, product reviews, and marketing copy without actively looking for AI.
The biggest AI exposure happens on Google searches and Amazon shopping. Most AI mentions are just brief references like "AI-powered" or "AI-enhanced" in product descriptions. Very few people actually visit ChatGPT or read news stories about AI developments.

Prompt of the Week
This week we're doing things a little differently. As you probably know, Claude 4 is here. And Anthropic just released their official prompt engineering best practices for the new flagship model. Inside, they say Claude 4 needs more explicit instructions than previous versions to get "above and beyond" behavior.
Key techniques include:
- Tell Claude what TO do instead of what NOT to do
- Add context explaining WHY you need specific behavior
- Use XML tags to control response format
- Match your prompt style to desired output style
For business applications, Claude 4 excels at parallel tool execution. The guide recommends this prompt: "For maximum efficiency, whenever you need to perform multiple independent operations, invoke all relevant tools simultaneously rather than sequentially."
The models also have new "thinking capabilities" for complex multi-step reasoning. Anthropic suggests being bold: "Don't hold back. Give it your all" produces better results than basic requests.
