Teams often have mis-aligned mental models of customer, problem, and differentiation.

Three co-founders can give three different answers to 'who exactly is your target customer?' The sprint forces explicit alignment.

Why: Mis-alignment at the start compounds into wasted months of building the wrong thing.

"We would have a conversation with founders... three co-founders have three different answers."

Going fast without clarity can actually slow you down.

AI-assisted builds feel productive but tend to be generic; you get data on what early users did, but zero data on the majority who bounced.

Why: Generic products fail to break through customer apathy and noise.

"Going fast can actually slow you down in the long run."

Differentiation must be defined from the customer’s perspective, not investor or tech-centric angles.

Classic consultant 2×2 grids feel like BS because they’re usually investor-facing and un-tested; the sprint forces customer-validated axes.

Why: Only customer-relevant differentiation drives adoption.

"These describe technology or they describe the market opportunity. They don't talk about the customer's perspective."

Use structured silence and a single decider to avoid endless debate.

Everyone writes answers alone, votes silently, then the designated decider picks; this conserves energy for the decisions that matter.

Why: Group brainstorms default to the loudest voice; silence surfaces all perspectives quickly.

"Using silence and using structure and then having a designated decision-making process, we can move through a lot of conversations very quickly."

Condense the entire strategy into one mad-libs sentence.

"If we solve [problem] for [customer] with [approach], they’ll choose us over [competitors] because of [Differentiator 1] and [Differentiator 2]."

Why: A single sentence keeps the team focused and testable.

"It's almost silly how simple this thing is, but really powerful for founders to have that clarity."

Map every way the customer already solves the problem, not just direct startups.

Include work-arounds, in-person options, spreadsheets, or ‘doing nothing’ as competitors.

Why: True competitive set reveals real switching barriers and positioning gaps.

"If this is an important problem, your customer is probably already solving it somehow."

Explicitly list unique insights, motivations, and capabilities before choosing differentiators.

Founders list personal unfair advantages (e.g., ex-Substack team knows network growth).

Why: Differentiators must be anchored in something the team can actually deliver better than incumbents.

"Startups can't compete with big companies on scale... they really have to dig deep and figure out, what can we do that nobody else is capable of doing?"

Plot every possible implementation path against multiple weighted lenses.

Lenses include customer delight, speed-to-market, growth potential, revenue, differentiation, and founder conviction.

Why: Visual trade-offs prevent emotional attachment to a single path and expose the best first bet.

"You either pick a lens or you just pick the consensus winner."
