The angel investment ladder treats startup investing like planting successive crops. Rather than selecting a handful of companies during one period, the investor deploys capital across multiple vintages, funds, and evolving technology themes. This matters because a whole cohort can be damaged by poor timing, mistaken assumptions, or a technology wave that fails to mature. Continued participation also preserves access to exceptional outliers that cannot be identified reliably in advance. Lindzen extends the principle to fund investors: committing to only one fund effectively cherry-picks a single vintage, while backing several funds creates broader exposure to the manager's process. The model's output is a paced, diversified program with realistic expectations, reserved capital, and tolerance for both misses and complete wipeouts.
Origin
Howard Lindzen described startup portfolios as crops and ladders while explaining how private investing differs from buying liquid stocks on Masters in Business.
Core principles
- 01Startup outcomes require repeated exposure rather than one vintage
- 02Entire groups of investments can fail together
- 03Technology waves change faster than private investments mature
- 04Misses are acceptable when the investor consistently sees quality deals
- 05Portfolio expectations must reflect the size of each niche
How to run it
- 1
Define a multi-vintage budget
Set the total capital available for startup investing and divide it across several years or fund vintages.
Pro tip Keep this allocation separate from money needed for living expenses or near-term goals.
Watch out Startup investments can remain illiquid for a decade or become worthless.
- 2
Place an initial cohort of bets
Build a diversified first vintage without assuming it will represent every future technology cycle.
Pro tip Use consistent underwriting rules so results can be compared across cohorts.
Watch out Do not mistake the success of one early investment for proof of repeatable skill.
- 3
Reserve follow-on capacity
Hold back capital for later rounds, new funds, and companies demonstrating stronger evidence.
Pro tip Establish follow-on criteria before founders request additional money.
Watch out Unplanned follow-ons can consume the capital intended for future vintages.
- 4
Repeat across cycles
Continue deploying as markets, platforms, and investment themes evolve.
Pro tip Review whether a former broad wave has become a smaller niche before setting return expectations.
Watch out Do not chase every new theme merely to appear diversified.
- 5
Evaluate cohorts, not anecdotes
Measure results by vintage, thesis, and process rather than celebrating one winner or fixating on one miss.
Pro tip Track whether the investor had access to major opportunities even when some were declined.
Watch out Outcome bias can make luck look like skill and disciplined misses look like incompetence.
- 6
Rebalance future exposure
Use evidence from prior crops to refine sector focus, check sizes, and reserve policies without abandoning diversification.
Pro tip Change the process only when several observations support the adjustment.
Watch out Private-market feedback arrives slowly and can encourage premature conclusions.
In the wild
Lindzen described evolving his focus from the broad social wave toward fintech while continuing to recognize smaller social niches. The ladder allows an investor to participate in successive waves rather than anchoring the entire portfolio to the theme that produced earlier wins.
→ Exposure evolves with technology while remaining diversified across investment years.
An investor allocates a venture budget across three sequential funds rather than placing everything in one vintage. One cohort suffers from poor timing, another produces modest returns, and a later fund captures a major outlier.
→ No single technology cycle determines the complete result.
Common mistakes
Betting on one crop
A single vintage can be overwhelmed by timing, correlated mistakes, or an unfavorable technology cycle.
Confusing one win with mastery
An early outlier may provide capital without teaching a repeatable investment process.
Failing to pace capital
Deploying everything immediately removes the ability to invest in later opportunities or support the strongest existing companies.
Is it for you?
Best for
It is best for qualified investors making repeated angel or venture allocations over many years.
Not ideal for
It is not ideal for anyone who needs near-term liquidity or cannot tolerate losing the full amount invested.
From the transcript
“you have to continually place bets.”
“building an angel investing ladder, I call it a ladder, or I call it crops.”
“it should be for three or four funds. It shouldn't be for one fund because then they're cherry picking.”
