How Altos Ventures builds generational companies through patient investing

Executive overview

Altos Ventures applies three principles from investment legend Jack McDonald to build durable tech companies over decades: the power law (only a small number of companies drive all returns), compounding (most value emerges in years 10–20, not 1–3), and hedgehog founders (maniacally focused on solving one problem). The firm partners with visionary founders who combine strong convictions with intellectual humility, taking a lifecycle approach to capital deployment and reinvestment.

Core insight: Most venture returns come from patient partnership with unflinching founders who stay focused on one problem for years.

The three founding principles

1. Power law: In any asset class, only a small number of companies drive nearly all returns—true even more dramatically in venture than public markets
2. Compounding: A penny doubling daily yields $10M+ by month end; similarly, startup value accrues in years 10–20, not years 1–3
3. Hedgehog vs. fox founders: Hedgehogs stay maniacally focused on one problem for life; foxes scatter across many projects and get distracted—hedgehogs endure the startup journey better

Why the power law reframes venture strategy

In the internet bubble, Altos marked up early companies and flipped them to larger funds. When those companies went public at inflated valuations then crashed to zero, the firm realized markups meant nothing without real value creation. This led to abandoning the flip-and-fund model in favor of decade-long partnerships focused on durable business fundamentals.

The hedgehog founder archetype

The strongest founders possess strong opinions loosely held. They develop conviction about the problem either through lived experience (solving their own pain) or deep industry study, but remain humble enough to change course when data contradicts their views. Mental plasticity—the ability to admit mistakes and course-correct—separates great founders from the rest.

Real-world example: PushPress

Founders were former CrossFit gym owners who built software to solve their own gym management pain. The company now employs ~100 people, many former gym owners and fitness professionals. Because founders live the category they serve, they deliver exceptional customer support and product intuition that outsiders cannot match.

Partnership over speed in deal-making

Founders often request term sheets overnight while claiming to seek a 10-year partner. Altos resists this contradiction; entering a multi-decade relationship without getting to know each other is misaligned. The preschool teacher analogy applies: teachers know children broadly, parents know their child best. VCs see patterns across many companies, but founders know their company most deeply. The best partnerships blend both perspectives.

How investors increase odds of success

Venture success is probabilistic and luck-dependent, but VCs can control inputs. The role is to expand the founder's thinking through pattern recognition, steward the company with humility, and help increase the odds of success by avoiding predictable mistakes and accelerating the path to greatness.

Altos' portfolio strategy

The firm is a global generalist technology investor with a flexible mandate. It leads Series A rounds but thinks of itself as a lifecycle investor, often starting small and deploying hundreds of millions across a company's lifetime—as with Roblox, which received $1.5M in the first round 16 years ago followed by hundreds of millions more before and after the IPO. Even post-IPO, Altos views Roblox as early-stage with vast untapped potential.
