1 Age bias in tech starts early. What is investors' strongest bias? Your age. 37% of founders believe startup investors bias against founders based on age (compared to 28% on gender and 26% on race). A whopping 89% of respondents agree that older people face age discrimination in the tech industry generally. And "older" doesn't mean octogenarians: On average, founders think tech industry ageism starts at 46 years old.
