My team has built e-commerce platforms that processed over $1 billion in revenue. What once cost me $3M and 18 months to build, I can now build in 3 months for $600.
But here's the problem no one talks about: SaaS is the worst of all worlds, and companies that rely on it will die.
The Cost Problem Is Real, But It's Not the Real Problem
Yes, SaaS costs are obscene. The numbers speak for themselves:
- 37signals saved $7M over 5 years by leaving the cloud
- Dropbox saved $75M in just 2 years
- DHH's Datadog bill hit $83K/year before he cancelled
- The average enterprise runs 410 SaaS apps, 53% of which go unused -- that's $18-21M in pure waste
But the cost isn't why SaaS will kill your company.
The Real Problem: SaaS Makes Every Company Identical
You're using the same tools as your competitors. The same CRM (Salesforce). The same analytics (Datadog). The same workflows (HubSpot).
Zero differentiation. Zero competitive advantage.
When your entire tech stack is off-the-shelf, what exactly is your moat? You don't have one. You're competing with one hand tied behind your back, paying for the privilege, and calling it a strategy.
You're Locked Into Their Roadmap, Not Yours
It gets worse. Need a competitive feature? You're one of 10,000 customers. Your request goes into a backlog you don't control. You wait six months or more.
Meanwhile, your competitor who owns their software? They ship it in a week.
You can't move fast. You can't innovate. You can't differentiate. You are operationally identical to everyone else in your market, and you're paying a premium for that mediocrity.
The Winners Already Know This
Netflix, Google, Stripe, Amazon -- none of them use commodity SaaS for their core systems. They build custom. That is their competitive advantage.
- Stripe: 15 million lines of custom code
- Google: 30% of all code is now AI-generated
Custom tooling isn't a nice-to-have. Custom tooling is the moat.
Here's What Changed: LLM Scaffolding Broke the Economics
The reason "build vs. buy" used to favour buying was cost and speed. That calculus has been obliterated:
- AI code generation makes developers 55% faster (GitHub Copilot data)
- 46% of all code is now AI-written
- What took 18 months now takes 3 months
- What cost $3M now costs $600
- What needed 25 engineers now needs 1 Architect + LLMs
Building custom is now cheaper than renting SaaS at scale.
With the right LLM scaffolding approach, Claude Opus can one-shot entire applications. The break-even point against SaaS subscriptions? Six to twelve months. Rip out the dead wood, invest in some smarts and the right scaffold, and you own your future.
The New Paradigm
The old question was: Build or Buy?
The new question is: Build or Die.
Companies that rely on SaaS:
- Can't differentiate
- Can't move fast
- Pay exponentially more as they scale
They will lose to competitors who own their software. Every time.
The framework for how to actually do this -- the architecture, the scaffolding, the approach -- is coming. If you're ready to stop renting your competitive advantage and start owning it, stay tuned.
