"I spend more time figuring out WHAT to test than actually testing."
"ChatGPT gives me ideas, but they're too generic. I need something specific to MY business model."
"Every session I explain everything again. Like I have amnesia."
"I've tried 5 different frameworks. They all make sense in theory, but I can't stick to any of them."
LEANSpark solves all of these
Context that persists. Methodology that sticks. Guidance that's specific to YOUR business model.
Your AI co-founder that guides you through systematic validation using the PDCA Learning Loop.

Structure, not just knowledge. Generic AI tools are conversational—they respond to what you say. LEANSpark is systematic—it runs structured processes.
Try this experiment: Upload my playbooks to ChatGPT and ask for a Business Model Design assessment. You'll get thoughtful advice. But try again tomorrow with the same canvas—you'll get different advice. Ask it to score your model 0-10 across 7 dimensions—the scores will drift. Tell it you're pivoting—it won't remember your previous models or experiments.
LEANSpark works like Claude Code for business models: Code can be tested. Business models can be scored. Experiments create data. Your validation history builds persistent context that gets smarter over time—not conversation memory that drifts.
LEANSpark doesn't just advise, it executes: Loads your canvas → Runs 7-dimension assessment → Detects mixed models → Generates focused variants → Asks permission → Updates your canvas. Repeatable. Testable. Systematic.
Generic AI optimizes for sounding helpful. LEANSpark optimizes for systematic validation.
Yes. Built in public through 6 Over-the-Shoulder episodes.
I used LEANSpark's 7-dimension stress-testing on my own business model, ran 90-day validation cycles, and documented the entire journey on YouTube. 209 founders joined for early access.

This is the same framework you'll use. Same stress-testing. Same 90-day cycles. Same decision frameworks.
Yes. LEANSpark builds a persistent memory of your business model, metrics, and experiments across all sessions.
Every conversation, assessment, and validation cycle adds to your project's context. The more you use LEANSpark, the smarter it gets about your specific business—spotting patterns, remembering past pivots, and connecting insights across your entire validation journey.
Immediate:
January 2026:
After Your First 90-Day Cycle:
Two ways to get access:
1. Preorder early access: $150
Lock in your 90-day cycle before public launch. Batched onboarding starting January 15th. Priority queue based on preorder date.
2. Monthly subscriptions: February 2026
General monthly signups open in February ($50/mo for 250 credits). Early access members keep their preorder pricing and priority support.
We're doing batched rollout to learn, fix issues, and improve the product between batches. This ensures quality over speed.
LEANSpark is designed to handle both routine tasks like Lean Canvas reviews and updates, as well as transformative work like experiment design and insight mapping that require deep methodology understanding.
Yes, it will. We started prototyping with a standalone terminal version for speed and simplicity, but the end goal is to have it coexist alongside your models and data inside LEANSTACK.
You'll be able to run it standalone and pull your data from LEANSTACK, or use it directly within the platform—whichever fits your workflow.
You can purchase top-ups anytime (50 credits for $30, 100 for $55, 250 for $125). Credits never expire.
Yes. LEANSpark accesses your models and data using OAuth and APIs—industry-standard secure authentication.
LEANSpark also asks for permission before making any changes to your models. You stay in control.
