  • Why Most Technical Products Fail at GTM - and It's Rarely the Product's Fault

    This story was originally published on HackerNoon at: https://hackernoon.com/why-most-technical-products-fail-at-gtm-and-its-rarely-the-products-fault.


    Most technical products don't fail because of bad engineering. Discover the 7 GTM mistakes engineering-led teams make and how better distribution drives growth.

    Most technical products don't fail because the product isn't good enough—they fail because no one sees, understands, or trusts them. Engineering-led teams often treat go-to-market as an afterthought, relying on documentation, word of mouth, or last-click attribution instead of building audience, credibility, and distribution early. In an era of AI search and fragmented attention, successful GTM means publishing where technical audiences already are and treating visibility as a core part of the product strategy.

  • Retired Not Rehired: How AI Is Changing That

    This story was originally published on HackerNoon at: https://hackernoon.com/retired-not-rehired-how-ai-is-changing-that.

    The Silver Tsunami is sending millions of retirees back to work - thin savings, delayed pensions, and a stalled job market leave little choice. They land in a hiring system where AI-powered ATS filters, an AI fluency gap, and ageism screen them out before a human sees their 30+ years of experience. But the same technology can flip the script: AI tools can reformat resumes to clear ATS filters, match deep experience to the right roles, and close the fluency gap. The move is to compete on accumulated expertise AI can't replicate - and use AI as the equalizer to get back in.
