When this applies
when an incumbent stakeholder has the option to use inside information/relationship to price a future transaction in their own favor
The takeaway
Removing your own ability to benefit from a future transaction removes the temptation to bias your advice about that transaction — trustworthy advice requires removing self-interest, not just intending to be unbiased.
Why it works
An investor with capital to deploy into later rounds has an incentive to preempt at a lower valuation; without that capital pool, the investor has no such incentive, so they can act purely as an advocate helping the founder raise the best possible external round.
One level up
Structural separation of interests is more reliable than personal integrity alone for sustaining trust over time.
Where it stops holding
This stops working when the founder actually values speed/certainty of insider capital over optimizing price, or when no outside capital is available at better terms.
Detail
situation: Companies funded by growth-fund-equipped firms risk the firm preempting their own next round at an advantaged valuation (lower basis).
decision: Benchmark deliberately has no growth fund, removing this conflict entirely.
outcome: Portfolio founders reportedly raise better Series Bs at higher valuations with more certainty, taking less aggregate dilution and owning more of their company at exit.
lesson: An investor's absence of a competing financial interest in a later round can itself be a source of value to the founder.
In their words
I believe that the founders own more of their companies at exit, at S1 time, whatever it is, in this case, for those reasons.
