Secrets of Sand Hill Road

Scott Kupor · 2019

How a venture firm actually operates — where its money comes from, what its own investors demand of it, and why that shapes every decision it makes about your company.

Why it is here

Written by the first employee at Andreessen Horowitz, this explains the layer above the deal: how funds raise from limited partners, how fund economics and fund life work, and why a firm behaves as it does at particular moments.

For an angel that is the missing context. When a lead pushes for a term, insists on a timeline, or declines to follow on, the explanation is usually structural — fund size, fund age, reserve policy, the pressure to show returns to their own investors. None of that is visible from outside and all of it affects your position.

It also demystifies the parts of a term sheet that Venture Deals covers, from the other side of the table, which makes the two genuinely complementary rather than redundant.

Read it if

You co-invest alongside institutional funds and want to understand what is driving their behaviour.

Skip it if

You invest only at pre-seed with other individuals and expect never to sit alongside a fund.

Secrets of Sand Hill Road: common questions

Why should an angel care how venture funds are structured?
Because fund structure explains lead behaviour. Reserve policy determines whether they can support the next round, fund age determines their appetite for a long hold, and pressure from their own investors determines how they behave in a difficult moment — all of which lands on your position.
How does this differ from Venture Deals?
Venture Deals explains the documents; this explains the institution behind them. Read together they cover both what a clause does and why the person across the table wants it.
