Good morning. This quarter's revenue and the business you'll run in three years are competing for the same hours — and this quarter always wins.

The Three Horizons

5 min read·Apply by lunch

The question

Sort everything your business will spend real effort on this quarter into three piles — earning today, building the next earner, seeding the one after — and look at the second and third piles: if the honest answer is that the core has quietly eaten them, what exactly will you be selling in three years, and why haven't you booked the hour that starts the rebalance?

The idea

In 1999 three McKinsey partners — Mehrdad Baghai, Steve Coley and David White — published The Alchemy of Growth, built on a study of companies that had sustained growth over decades rather than riding one product to maturity. Their finding became the three horizons. Horizon one is the core: the businesses producing today's cash, to be defended and extended. Horizon two is the emerging engines: real ventures with real customers that need investment to scale into the next core. Horizon three is the options: seeds, experiments and stakes in possible futures, most of which will die. The claim that matters is the one most people miss — the horizons are not phases you move through in sequence; healthy companies hold all three at once, as a portfolio, permanently. The trap is that horizon one devours everything. The core is urgent, measurable and politically strong, so when the quarter tightens, horizons two and three fund the shortfall — and the growth gap this creates arrives two or three years later, exactly on schedule, when the core matures and nothing is standing behind it. Most people discover the gap at the moment it can no longer be closed.

The framework

01
Put everything on one page, in three columns.
List everything the business spends meaningful effort on and sort it: horizon one pays today's bills; horizon two has genuine external validation — paying customers, real usage — but needs investment to scale; horizon three is an idea, an experiment, an option. Do the sort honestly and two findings are common: the second and third columns are nearly empty, or they are full of impostors — incremental improvements to the core dressed up as innovation because 'innovation' wins budget. A faster checkout is horizon one. A new product for a new customer is horizon two. The sorting is the diagnosis, and it takes one page and one honest hour.
02
Judge each horizon on its own scoreboard.
Horizon one is judged on margin, share and efficiency — the metrics of a machine being run well. Horizon two is judged on revenue growth and customer adoption — is the engine catching, is the path to scale real. Horizon three is judged on learning per dollar — is the option alive, and what did we find out. The predictable killing move is applying horizon-one metrics down the ladder: put a horizon-three seed in front of an ROI review and the numbers are always terrible, so it gets cut, and the cut feels like rigour. It isn't rigour; it is measuring a seed with a harvest scale. A venture judged on the wrong horizon's scoreboard doesn't fail — it gets executed.
03
Protect the far horizons structurally, not intentionally.
Good intentions lose to the quarter every single time, because the core can always show exactly what one more person or dollar would earn, and the far horizons can't. So the protection has to be structural: a ring-fenced budget the core cannot raid, named people whose job is the second horizon — not 'twenty per cent of someone's time when the core is quiet', which rounds to zero — and a separate review where far-horizon work is examined on its own scoreboard. In a small company this might be one protected afternoon a week and a few thousand dollars of experiment budget; the size matters far less than the wall. If the boundary is enforced by willpower, it has already fallen.
04
Rebalance on a rhythm — the horizons move.
Today's core was once somebody's horizon-three bet, and the portfolio only works if things flow: seeds graduate to ventures or get killed cleanly, ventures scale into the core or get sold or shut, and the freed resources fund new seeds. Review the page quarterly and force the honest calls both ways — including the kill decisions, because a horizon three full of zombie experiments nobody will end is just a slower way of having no options. And note the inverse failure, common in founders: living entirely in horizon three, chasing the next thing while the core that funds it all quietly starves. The discipline cuts both ways — the portfolio needs a tended core exactly as much as it needs seeds.
