Do a week of market research in one hour” · you could be next

Pick a market you know nothing about (pet insurance, industrial sensors, padel courts) and produce a research memo in one hour, using AI for the heavy lifting.

What your memo must include

  • Market size with 2 sources you actually checked
  • The 3 players that matter and how they differ
  • One surprising insight a casual observer would miss

How to do it

Use AI search tools (Perplexity, Gemini, ChatGPT with browsing) to gather, then Claude to structure and pressure-test. Verify every number: AI invents statistics with total confidence.

Turn in

A public link to the memo, your time spent honestly stated, and which tools did what.
