We build SaaS products with Claude at the core — architecture, billing, and evaluation infrastructure — to a launch-ready MVP, not just a working demo.
Build Your SaaS on Claude — From Architecture to First Paying Customer
In short: Northell builds SaaS products with Claude at the core: architecture, billing, prompt and evaluation infrastructure, and a launch-ready MVP.
Key takeaways
- Full-stack SaaS build with Claude integrated as a core product feature.
- Billing, auth, and multi-tenancy handled alongside the AI layer.
- Evaluation infrastructure built in from day one, not added post-launch.
Frequently asked questions
Do you build the whole SaaS, or just the Claude integration?
The whole product — auth, billing, multi-tenancy, and infrastructure — with Claude integrated as a core feature rather than bolted onto a separately-built app.
How is this different from a generic SaaS boilerplate?
Boilerplates handle the non-AI plumbing; the harder part is designing where Claude sits in your product, its cost model per user, and evaluation so quality doesn't drift as you scale. That's the part we specialize in.
What does 'launch-ready MVP' actually include?
A working product with real auth, billing, and the core Claude-powered feature — enough to onboard paying customers, not a demo you'd need to rebuild before launch.
How do you handle per-user AI costs at scale?
Cost modeling per plan tier, prompt caching, and usage limits are built into the architecture from the start so unit economics hold as you grow.
What's a realistic timeline to launch?
8-12 weeks for a focused MVP, depending on feature scope and how much of the Claude-powered workflow needs custom evaluation.
