Strategy, experimentation and operating systems for building useful ventures that survive contact with customers.

## [Cialdini in the funnel: six levers, one honesty test](https://lenvanderhof.com/en/blog/cialdini-in-the-funnel/)

Reciprocity is a real sample. A fake crowd is still a fake crowd. Name the lever, then keep it.

## [Do you need a literary agent for nonfiction? What agents do, what they cost, and when to publish yourself](https://lenvanderhof.com/en/blog/do-you-need-a-literary-agent/)

An agent is a door to large publishers. If you are not going through that door, you need a production system instead.

## [Downstream effects: why the real cost of a decision lands later, and somewhere else](https://lenvanderhof.com/en/blog/downstream-effects/)

Every choice starts a river. Most teams only watch the first bend. This is the operator definition of downstream effects, and a method you can run this week.

## [Downstream effects or affects? The one-line rule, and the two exceptions](https://lenvanderhof.com/en/blog/downstream-effects-or-affects/)

Affect is what a decision does. Effect is what it leaves behind.

## [Downstream impact, consequence, implication, outcome, effect: five words, five jobs](https://lenvanderhof.com/en/blog/downstream-impact-meaning/)

Pick the word by the question it answers: what came out, how hard it hit, who has to live with it, what it means next.

## [A go-to-market system that survives the first ten customers](https://lenvanderhof.com/en/blog/gtm-that-survives-ten-customers/)

The deck is a prior. The first customers are the reality-test. Write one sourced claim per name.

## [Kahneman for marketing: System 1 is not a permission slip](https://lenvanderhof.com/en/blog/kahneman-for-marketing/)

Losses weigh more than matching gains in prospect theory. That is a description. It is not a brief to frighten the buyer.

## [Len or a fractional CAIO: which work do you need?](https://lenvanderhof.com/en/blog/len-vs-fractional-caio/)

One role owns AI across the company. The other closes one decision or installs one system. Pick by the size of the problem.

## [Marketing nudges are choice architecture, not a growth hack](https://lenvanderhof.com/en/blog/marketing-nudges-are-choice-architecture/)

The fruit at eye height is a decision. So is the pre-ticked box. Name it, or someone else already did.

## [Positioning is a decision, not a tagline](https://lenvanderhof.com/en/blog/positioning-is-a-decision/)

If the homepage still fits the people you refused, it is a tagline.

## [Pricing psychology: a price is never a naked number](https://lenvanderhof.com/en/blog/pricing-psychology/)

If the only lever is 'make it feel cheaper,' you do not have psychology. You have a trick looking for a page.

## [What is a roster? From the Monday rota to a team of AI agents](https://lenvanderhof.com/en/blog/roster-meaning/)

The word started as a Dutch gridiron. The idea still fits your staff, your agencies and your AI agents.

## [Second-order thinking audit: the first-order metric is green](https://lenvanderhof.com/en/blog/second-order-thinking-audit/)

If you cannot name the later bill in the meeting, you do not have second-order thinking. You have optimism with a lag.

## [What are downstream effects?](https://lenvanderhof.com/en/blog/what-are-downstream-effects/)

The first-order metric can be green. The cost still has to land somewhere.

## [What is a deal architect?](https://lenvanderhof.com/en/blog/what-is-a-deal-architect/)

The visible number is rarely the deal. The options after signature are.

## [What is a dominated AI model? Better and cheaper is only half the test](https://lenvanderhof.com/en/blog/what-is-a-dominated-model/)

Another model is better and no dearer. Before you switch, ask the question the label skips: can it still do your job?
