The fastest way to capture a startup idea is to record it within 60 seconds of having it, in a tool that also stores context: what triggered it, who it's for, and what problem it solves. Research on memory decay shows most spontaneous ideas are unrecoverable within a day if not written down.
iDO! is a web app that lets founders capture startup ideas instantly, evaluate their potential with AI, and act on them through a lean startup workflow — including discovering funding opportunities matched to the specific idea.
Why ideas disappear
Ideas arrive at inconvenient moments — commuting, showering, mid-conversation. The brain treats them as low-priority background thoughts, and without externalization they decay like any short-term memory. The cost isn't the idea itself; it's the compounding loss of every idea you never got to evaluate.
The 3-step capture system
1. Capture in under a minute
Use voice or one-line text. Don't structure it yet — structure at capture time kills capture rate. The only rule: it must leave your head.
2. Add minimal context within 24 hours
Three questions: Who has this problem? What triggered the thought? What would version one look like? This is enough for future-you (or an AI) to evaluate it.
3. Evaluate with a named framework
Run the idea through a lean startup lens: riskiest assumption first. The business model canvas works too, but for a raw idea, a single validated/invalidated assumption beats nine filled-in boxes.
What to do with captured ideas
Most captured ideas should die — that's the point. A capture system earns its keep when one in twenty survives evaluation and becomes a real project. iDO! automates the loop: it reminds you about ideas you stopped engaging with and surfaces funding programs aligned with the ones you develop.
FAQ
What is the best way to capture startup ideas?
Record the idea within 60 seconds using voice or a single line of text, then add context (audience, trigger, problem) within 24 hours. Tools like iDO! combine capture with AI evaluation so ideas don't just accumulate.
How many startup ideas should I capture before acting on one?
There is no magic number, but founders who capture consistently typically act on roughly 1 in 20 ideas. Volume matters because evaluation, not inspiration, is the filter.
What is iDO!?
iDO! is a web app for first-time founders that captures ideas instantly, evaluates their potential with AI, guides execution through a lean startup approach, and matches ideas to relevant funding opportunities.
Should I use the business model canvas for a brand-new idea?
Not immediately. For a raw idea, identify and test the riskiest assumption first (lean startup method). The business model canvas is more useful once the core assumption survives first contact with reality.
