Big Tech Has Spent Billions Acquiring AI Smart Home Startups

The pattern is clear: when innovative companies successfully integrate AI into everyday products, tech giants pay billions to acquire them.

Google paid $3.2B for Nest.
Amazon spent $1.2B on Ring.
Generac spent $770M on EcoBee.

Now, a new AI-powered smart home company is following their exact path to acquisition—but is still available to everyday investors at just $1.90 per share.

With proprietary technology that connects window coverings to all major AI ecosystems, this startup has achieved what big tech wants most: seamless AI integration into daily home life.

Over 10 patents, 200% year-over-year growth, and a forecast to 5x revenue this year — this company is moving fast to seize the smart home opportunity.

The acquisition pattern is predictable. The opportunity to get in before it happens is not.

Do you know how long it took Hotmail to go from launch to exit?

This week we have a blast from the past, but one worth another look in today’s startup environment.

In 1996, email was for techies, academics, and corporate insiders, not normal everyday people.

Sabeer Bhatia and Jack Smith set out to change that—by putting free, web-based email into everyone’s hands.

But with no marketing budget and zero brand recognition, they needed a move that would punch above its weight.

The Classic Chess Move: Turn Every User Into a Marketer

Instead of buying ads, Hotmail embedded a simple line at the bottom of every outgoing email:

“PS: I love you. Get your free email at Hotmail.”

Every message sent became a viral invitation—delivered by a trusted sender, straight to the inboxes of friends, family, and colleagues. Each signature included a clickable link, making it friction-less for recipients to sign up in seconds.

The Results:

• 🚀 1 million users in 6 months

• 🚀 12 million users in 18 months (when there were only ~70 million internet users globally)

• 🚀 Acquired by Microsoft for $400M in 1997—the largest all-cash internet startup deal of its era just one year after launch

Why It Worked:

• Pattern Interrupt: “PS: I love you” felt personal, not like an ad. It was a friendly, curiosity-piquing footnote that cut through inbox noise

• Built-In Trust: Emails came from people you knew—making the invite feel safe and authentic.

• Zero Friction: The Hotmail link took you straight to a dead-simple signup page. No searching, no hurdles.

• Exponential Reach: As more users joined, more emails went out, creating a compounding viral loop.

Why Microsoft Paid Top Dollar for Hotmail

Microsoft wasn’t just buying a product—they were buying a viral engine and a massive, loyal user base. By late 1997, Hotmail had over 8.5 million subscribers, with millions actively using the service every month

. For Microsoft, Hotmail solved several strategic challenges:

• Instant Scale: Hotmail’s user base more than doubled the number of email accounts Microsoft controlled overnight, catapulting MSN into direct competition with AOL

• Webmail Pioneer: Hotmail’s technology allowed users to access a permanent email address from any PC, anywhere in the world—a leap beyond desktop-bound email clients

• Eyeballs and Engagement: Hotmail users became a captive audience for Microsoft to cross-promote MSN’s other services—news, shopping, travel, and more

• Proof of Viral Growth: Microsoft admired that Hotmail’s growth was “purely through word of mouth”—a testament to product-market fit and user evangelism

• Technology Synergy: Hotmail’s scalable backend and web-based approach could be integrated into Microsoft’s Windows NT and Exchange platforms, strengthening their enterprise and consumer offerings

💡 How to Apply the Hotmail Playbook:

1. Embed Virality in Your Product

Find a way for every user action to naturally promote your product—think “Powered by Shopify” or “Sent from iPhone.” Make it subtle, friendly, and most importantly frictionless.

2. Leverage Social Proof

Turn your users into advocates. A recommendation from a friend or colleague is 10x more powerful than any paid ad.

3. Test the Unexpected

Don’t be afraid of unconventional copy or placement. “PS: I love you” worked because it was weird, warm, and totally unexpected.

Key Takeaways from Hotmail’s $400M Deal:

• 🐇 Keep it Simple: Hotmail didn’t develop some elaborate plan, they simply hit the exact pain point their market wanted; free email with zero friction.​

• 🐇 Embed Viral Sharing Into the Platform: Embed your product in everything your users see with a call to action and a clear benefit.

• 🐇 Make it Easy: Make signup and sharing effortless to maximize reach.​

• 🐇 Acquisitions Can Move Fast: A high-quality, engaged user base is irresistible to acquirers.
