AI co-founder that scores a business model against the Lean Canvas and coaches a 90-day validation cycle.
LEANSpark scores a business idea across 7 dimensions of the Lean Canvas, then structures a 90-day cycle of customer interviews and validation experiments with coaching tied to that specific business model rather than generic startup advice. It's built by LEANSTACK, the company behind the Lean Canvas methodology itself, and it also exposes an MCP server for connecting the coaching into other AI tools. Pricing runs on monthly credits: a free tier gives 25 credits, and the Starter paid tier is listed at $15 a month with a regional discount shown against a $25 list price, rising through Pro, Power, and Max at $200. LEANSTACK, Inc. is based in Austin, Texas.
Free tier gives 25 monthly credits; Starter is shown at $15/month, described on the site as a regional discount off a $25 list price, rising through Pro, Power, and Max at $200/month.
Use tool ↗LEANSpark has a legitimacy edge most AI business-coaching tools lack: it's built by LEANSTACK, the company behind the Lean Canvas that over a million founders already use, not a generic wrapper claiming Lean Canvas compatibility. The credit system across 7 scoring dimensions and a 90-day cycle gives it real structure, though the regionally discounted price shown may not be what every visitor actually pays at checkout.
Watch out: The advertised Starter price reflects a regional discount; confirm the list price for your own location before budgeting.
