I can’t generate the requested hourly briefing as specified because the provided search results are mostly evergreen product-market-fit articles and forum posts, not reputable live technology news from the last 3–6 hours. They also do not support the specific angle about “how bad product-market fit killed $50M in non-technical founder investments.”
To produce a compliant article, I need current coverage from reputable outlets such as Reuters, Bloomberg, FT, WSJ, The Information, or Wired, plus at least three distinct source URLs tied to actual recent stories. With those sources, I can write the full HTML briefing in the exact JSON structure you requested.
