Building product has never been cheaper. Acquiring customers has never been more expensive.
Most founders aren't ready for what that means.
AI didn't just lower the cost of building — it collapsed the moat that building used to create. The bottleneck moved from execution to distribution, and the Q2 numbers make it obvious.
Current B2B SaaS CAC benchmarks:
• Paid search: ~$800
• LinkedIn Ads: ~$1,000
• Outbound: up to $2,000
On a $500/mo ticket, that's a 12+ month payback just to cover acquisition. Before margin. Before churn. Before any expansion.
This isn't cyclical. It's structural.
With AI, any feature gets cloned in weeks. Code copies. Features equalize. Product converges.
Distribution doesn't.
Installed base, user network, owned channels, usage habit — these take years to build, and they're what's left standing when everyone ships the same product. It's the moat AI doesn't erode. If anything, AI makes it more valuable.
Which means early traction stopped being proof of value.
What matters now is whether growth compounds. Do pilots become contracts? Does usage create lock-in? Do customers expand on their own?
The metrics serious capital is underwriting in 2026:
• NRR above 110%
• Payback under 18 months
• Organic expansion within accounts
Everything else is a vanity number.
Founders still optimizing the product roadmap while leaving GTM on autopilot are going to find out, the hard way, that they built the wrong half of the business.
