The tension between concentrated bets with heavy follow-on versus diversified early bets with minimal reserves is one of VC's most persistent strategic debates.

LinkedIn: Should VCs Be More Open to Spray and Pray Investing

Should VCs be more open to the spray & pray approach?

One of my favorite debates resurfaced again this week at the RAISE conference here in SF.

In one corner: LPs and GPs who believe in concentrated bets in few companies with significant follow-on capital.

In the other: GPs (and fewer LPs) who believe in more diversified bets into very early companies with more ownership upfront and less follow-on capital.

Look, I get it. Many LPs believe that the core value of the VC is the picking - so if your portfolio is 2-3x bigger than most seed-stage VCs, it signals you don't know what you're looking for.

Of course a counter point may be that if you take more swings, each individual bet can be less consensus. Easier to back the wildest ideas if the fund has 50 portcos vs 25.

Let's look at some (๐˜€๐—ถ๐—บ๐˜‚๐—น๐—ฎ๐˜๐—ฒ๐—ฑ) data. Chart below is from Dan Gray at Equidam who everyone should go follow.

It looks at two portfolio strategies available to a VC manager with a $50 million fund (so $40M of investable capital).

  • Conviction = 20 portfolio companies at $2M each

  • Diversified / "Spray and Pray" = 100 portfolio companies at $0.4M each

After many assumptions, the diversified portfolio beats the concentrated one for MOIC (Multiple on Invested Capital) at every point along the curve except for the stellar funds.

Said differently - if you are a top 5% fund, concentration wins. If youโ€™re not, diversification wins.

Now look, there are tons of other factors to consider. Things like ability to follow-on into your winners, time available to support each portfolio founder, etc.

Come hang out (virtually) on 10/29 at 10am PT and chat about fund construction and performance with me: https://lnkd.in/geibU_Bn
