Key takeaways from Lenny's podcast: "
Identify your bullseye customer in one day | Michael Margolis"
Imagine saving months of work on a product idea—by getting it right in one day.
That’s the promise of the Bullseye Customer Sprint, a framework shared by Michael Margolis (UX Research Partner at GV). It’s all about focusing on the right customer at the start of your journey—avoiding wasted effort and accelerating clarity for your team.
Instead of chasing broad customer profiles, Margolis advises narrowing down to a small, specific group with shared needs and behaviors. Teams identify these customers through key questions, selecting five for interviews in a structured sprint. Over one day, they observe reactions to three distinct product prototypes, gathering insights from customer feedback and past experiences. This process reveals what resonates, avoids reliance on hypotheticals, and pinpoints what to prioritise or skip.
Clarity is the reward. Margolis’s framework ensures teams refine their product-market fit and move forward with confidence, a blueprint detailed in his book Learn More Faster.
Here’s how it works:
1. Define your Bullseye Customer.- It’s the most likely group to adopt your product—not your entire target market.
- Narrowing down feels comically specific but is key (think "users who buy refrigerated specialty meds").
- Use seven-ish criteria: demographics, past behaviours, trigger events, etc.
2. Talk to the right people.- Run short, focused interviews with five bullseye customers.
- Spend the first half uncovering their past experiences—because what they’ve done matters more than what they say they’ll do.
- Share 3 simple prototypes to learn what resonates (or doesn’t).
3. Make it a team sport.- Host “watch parties” for the whole team to observe live interviews.
- Assign roles for note-taking and debriefing.
- Align quickly—so everyone’s clear on what’s next by the end of the day.
4. Compare Prototypes to Uncover What Works.- Create 3 distinct versions of your concept—each with clear, contrasting value propositions.
- Avoid perfecting the design; focus on the messaging and what each version promises.
- Watch for patterns in what customers love, ignore, or critique to identify the most valuable features.
5. Prioritise Past Behaviour Over Predictions.- People often overestimate what they’ll do in the future.
- Anchor your insights on their past actions and experiences—how they’ve solved similar problems before.
- This approach reduces guesswork and gives you confidence in building solutions that match real-world needs.
