SOFTWARE IS DEAD…AGAIN!

Cloud software valuations have cratered to 10-year lows, with the median NTM revenue multiple hitting 4.1x. Investor confidence in the SaaS business model is fracturing as AI disruption risks threaten the retention rates and terminal value assumptions that powered the last decade of software investing. The path back requires companies to prove stable retention over multiple quarters.

LEADERS, GAINERS, AND UNEXPECTED WINNERS IN THE ENTERPRISE AI ARMS RACE

a16z surveyed 100 Global 2000 CIOs and found OpenAI still leads enterprise AI with 78% production usage, but Anthropic posted the largest share gain at +25% and now sits at 44% penetration. The surprise winner in enterprise apps is still Microsoft, not the startups dominating tech Twitter. Average enterprise AI spend rose from $4.5M to $7M and is expected to hit $11.6M this year.

THE BEST AI STARTUPS DO THE TRAINING FOR YOU. IT'S ON YOU TO MAKE THE AGENT AWESOME — NOT YOUR CUSTOMERS

The old model was to sell the software and let the customer figure it out. Businesses now need to do the work to make their AI great before they hand over the keys. AI agents will fail if improperly contained. It is up to the AI vendor to make it work. Customers shouldn't have to get agents to work.

WHAT TAM SHOULD ACTUALLY TELL YOU

Stop calculating “potential customers × potential price” and start with what the world currently spends solving your problem. That's your actual market today. Everything beyond that isn't market size, it's a thesis about growth. Most founders are stacking 3-5 speculative theses without realizing it, and since each compounds risk exponentially (30% × 30% × 30%), understanding this can dramatically improve how you allocate time and opportunity cost.

HOW PRODUCT DISCOVERY CHANGES WITH AI

AI has collapsed the cost and time of building and testing products, which means feasibility, viability, and usability are no longer the hard parts: desirability is. The critical bottleneck in product discovery is now understanding what customers actually want. Teams need to shift investment toward deeper customer insight and research to answer the fundamental question before building anything.

THE ORIGINS OF GENERATIONAL COMPANIES

Microsoft, Oracle, NVIDIA, and Starbucks all started by selling something to a tiny, often invisible market before stumbling into bigger opportunities. The playbook isn't “envision a radically different future and build it,” it's figure out a real need by selling, learn by iterating on what doesn't work, avoid trying to predict the future or convince markets, and stay in the game long enough to catch a demand wave when it hits.
