    With Stephen Miller's positive test, this debate prep is looking like a very scary room to have been inside. 6 of 10 participants now confirmed positives. whcovidtracker.com/events

    Getting from seed to Series A is difficult AF at the moment. Glut of startups at every stage, lots of bridging and extensions, lots of anxiety beneath the 1 or 2 massive AI round headlines. Hoping many are trying to avoid raising after their seeds but I'm skeptical

    Here's a new view - % of tests coming back positive (x-axis) and tests per million pop (y-axis). 9 states are back over 10% positive tests. But the gap between AZ and everyone else is rather startling. @_stah @SaskiaPopescu

    Not sure we're grasping the situation fully in the Midwest re: #COVID right now. 10 of 12 states are at record high hospitalizations. The other two will be there in a matter of days. No Midwest state has falling cases right now. These figures will contintue to climb. 1/2

    Replying to @COVID19Tracking
    Hospitalized population in the 3 largest states continues to head in the right direction - progress has been especially rapid in Texas.

    Hey NYT, fixed your graphs for you. Theirs in red, mine in blue and orange. @NateSilver538 @nytimes. Don't show case growth and not test growth - the wrong conclusions are easy to draw! @justin_hart @aginnt @Noahpinion @CarlBialik covidcharts.tech/overlay

    Getting from Series A to B is actually harder (in percentage terms) than from Seed to A. Used to be about 25% did so in under 2 years, latest cohort with data is at 9%.

    How much do VC-backed founders ACTUALLY OWN of their companies over time? Might be less than you expect. The median ownership for the founding team after a Series A sits at 36.1%, according to our study of over 14,000 US startups. The full report has much more data broken out

    Pre-seed at $11M and seed at $20M? That’s today’s market. Worth noting that median time between seed and A sits at just over 2 years. But the cohort doing it in less than 18 months has grown a bit of late.

    In AZ, 7-day avg deaths have doubled since May 27, from 12 to 24. And if you find yourself thinking, "Well, that's still not many"... On May 27 AZ saw 479 new cases. Today it was 3,593. Over 7.5x as many. Tests only up 2x. What do you think happens now?

    We should be surging vaccines into Michigan (even if we keep them for a week or two from other states). Everyone in Michigan over 16 should be bombarded with vaccine appointment availability - now is the moment.

    Early stage VCs should (probably, on average) make more investments. Lots of objections, some of them very valid. But the general disdain for "spray and pray" is pretty anti-math. Link to the full argument as laid out by @credistick in following post
