As per HN guidelines (see link at the bottom of the page), &quot;Please submit the original source&quot;.<p>The original source for this graph is a report from cbinsights.com. The graph was first reproduced here:<p><a href="http:&#x2F;&#x2F;thenextweb.com&#x2F;insider&#x2F;2014&#x2F;09&#x2F;25&#x2F;top-20-reasons-startups-fail-report&#x2F;" rel="nofollow">http:&#x2F;&#x2F;thenextweb.com&#x2F;insider&#x2F;2014&#x2F;09&#x2F;25&#x2F;top-20-reasons-star...</a><p>But unlike the Twitter posting, that article also links to the original detailed startup post-mortems, of which the graph is only a summary:<p><a href="https:&#x2F;&#x2F;www.cbinsights.com&#x2F;blog&#x2F;startup-failure-post-mortem&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cbinsights.com&#x2F;blog&#x2F;startup-failure-post-mortem&#x2F;</a><p>Discussion on HN from when the post-mortems were originally posted: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=7093147" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=7093147</a><p>But note that the collection of post-mortems was updated a few times, most recently on 12&#x2F;3&#x2F;15.<p>The submitted tweet doesn&#x27;t have any information about its source (even the reference to cbinsights.com is mostly cropped from the image).
