The framework has two halves: a behavioural signal and a pre-positioning playbook. The signal Wenger trusts is not price but the appearance of large-scale incubation efforts, where investors conclude they do not need an entrepreneur and can simply start the company themselves. He recognised the pattern because he had raised money into an incubator at the end of the dot-com bubble. When that tell appeared in 2021, the response was mechanical: take liquidity in anything sellable, and instruct every portfolio company to raise while raising was still easy. Once the correction arrived, the second instruction followed: make the money last far longer than the plan assumed, because the era of funding one-to-four million dollars a month of burn against forty percent growth was over. He also frames the correction as trickling down from public markets, through structured late-stage rounds, to early-stage valuations last, which is why early-stage founders often feel it late.
Origin
Built from Wenger's experience raising money into an incubator at the end of the dot-com bubble, then applied at Union Square Ventures across the 2021 peak.
Core principles
- 01Bubbles are not predicted by valuation alone; they are signalled by behaviour.
- 02When capital believes it can replace the entrepreneur, the cycle is near its tail.
- 03Everything useful must be done before the correction, not during it.
- 04Corrections trickle down: public markets first, late stage next, early stage last.
- 05There will always be another bubble, so build the response into your operating rhythm.
How to run it
- 1
Track behavioural tells of the cycle's tail
Look for signs that capital has become too easy: waves of incubators, investors starting companies themselves, and money moving without a thesis.
Pro tip Ask people who lived through the previous bust which tells they remember; the tells rhyme.
Watch out Valuation alone is a weak signal because the headline number often hides structure.
- 2
Take liquidity while the window is open
Sell what can be sold before the correction rather than waiting for a better print. Doing things early is the whole advantage.
Pro tip Decide sale thresholds in advance so the decision is not made under emotional pressure.
Watch out Liquidity disappears far faster than valuations fall.
- 3
Push the portfolio to raise before it needs to
Instruct every company that can raise to raise, regardless of whether their model says they need the money yet.
Pro tip Frame it to founders as buying option value, not as a prediction.
Watch out Companies that wait until they need capital raise into the worst possible conditions.
- 4
Reset the runway assumption after the raise
Tell companies that already raised to make the money last much longer than the plan assumed at the time of the round. Treat it as a long-term adjustment, not a one or two month blip.
Pro tip Rebuild the plan from a burn multiple rather than from a growth target.
Watch out Trimming as if this were a short blip forces a second, harder round of cuts later.
- 5
Segment the portfolio by growth and efficiency
Companies growing very fast or with something very compelling can still raise. Companies growing moderately must grow very efficiently. Moderate growth plus heavy inefficiency is the dangerous quadrant.
Pro tip There is very little one-size-fits-all advice, so make the diagnosis per company.
Watch out Blanket cost-cutting advice damages the companies that should be pressing their advantage.
- 6
Bring in people who survived the last bust
Convene the portfolio and let CEOs who managed through the dot-com implosion describe how hard funding can get. Lived testimony moves founders that a partner memo does not.
Pro tip Do this as a single all-portfolio call so the message is consistent.
In the wild
Seeing the incubation wave as the tail-end tell, USV took a lot of liquidity in 2021, sold what it could, and told every portfolio company to raise money. At the beginning of the following year it held a call for all portfolio companies, with CEOs who had lived through the dot-com implosion describing how difficult funding environments become, and told everyone who had raised successfully to stretch the money far beyond the original plan.
→ By the time the correction hit, very few companies in the portfolio needed to raise.
Common mistakes
Waiting for a valuation signal
Headline prices lag and often conceal warrant coverage and structure. Behavioural tells move earlier than the numbers.
Treating the correction as a blip
Planning for one or two difficult months rather than a long-term adjustment produces repeated, morale-destroying rounds of cuts.
Applying one playbook to every company
A fast-growing company and a moderately growing inefficient one need opposite responses; uniform burn-cutting advice harms one of them.
Is it for you?
Best for
Fund managers and founders who need to act ahead of a funding-market correction rather than during it.
Not ideal for
Anyone seeking precise market timing; the signal is directional and behavioural, not a dated call.
From the transcript
“I think when investors think, oh, I don't even need the entrepreneur, I can just start the company myself. That's kind of when you know…”
“So in twenty one, we took a lot of liquidity, we sold a lot of things that we were able to sell, and we told…”
“you've got to make this money last much longer than you thought when you raised it”
