Customer discovery sprint
Stop guessing who your customer is, get the evidence and agreement
Every week your team debates who you're building for is a week of wasted team time, especially engineering — whether in tokens and/or human hours. The Bullseye Customer Sprint replaces circular debate with five live customer interviews, giving you an evidence-based roadmap that your team actually agrees on.
Product-market fit is hard. This replaces wishful thinking with evidence in about two mos instead of 6+ mos of guessing. You'll move with conviction, not just speed.
- Align your team: everyone hears a human customer say the same thing, at the same time
- Save your protect runway: stop building features for a customer who lives in your head

How it works
The Bullseye Customer Sprint is a 3-phase process.
Phase 1: The hypothesis (wks 1-3)
Extract your team's assumptions about who you're building for, distilling them into a single critical question. Then, draft your Bullseye Customer one-liner: a specific role, at a specific company, with a specific trigger, using a current solution, but needing a different outcome.
Example: "Sales VP at a scale-up who just missed monthly targets, currently relying on spreadsheets but needs real-time pipeline visibility."
Phase 2: The fact-finding (wks 4-6)
Your team watches customer interviews live — five discovery interviews with testing three prototypes. We debrief immediately after each one. (Watching via a digital "two-way mirror" so we don't spook the participant.) When your co-founder, PM, and key team members hear the customer say the same thing at the same time, that ends the debate. The biases are all on the table. No working in hindsight. Just evidence.
Phase 3: The direction (wks 7-8)
You'll walk away with:
- Your Bullseye Customer hypothesis — specific, testable, based on evidence
- Your archive of evidence — all five recorded and transcribed interviews (read: your record of truth)
- Your actionable who/what/when roadmap — so product, sales, and marketing know exactly who they're building for come Mon morning
Can be paired for best application with a Listening Cycle for ongoing customer calibration.

Benefits
What you will get
Know the truth about your customer
In about two mos, your whole team hears the same customers say the same things. You'll know who your customer is — or who they definitely aren't.
Alignment happens as a part of the process
Five customer conversations eliminate the debate. Product decisions shift from "I think" to "they said."
Avoid wasting time on the wrong direction
Every week you're uncertain about your customer, you're potentially burning time and momentum on misaligned work. The sprint stakes clarity before you waste months building for the wrong person.
Your team leaves with a folder of proof
Recorded interviews, your Bullseye Customer hypothesis, and a roadmap.
What we guarantee
Sometimes, the evidence proves your hypothesis wrong. And that's a victory.
Finding out "no" in two mos costs $20K. On the other hand, finding out "no" in 12 months costs way more, maybe your entire runway.
The sprint is designed to get you the truth — not just head-nodding validation. If the evidence points to a different kind of customer, we pivot — and we're honest about what that means for next steps. You're never left hanging.
Case study
How Replay found their customers — five hypotheses, six mos, a clear Builder
The founding team behind Replay built nut.new — an AI vibe coding app that lets non-developers build and test working web apps. Their starting hypothesis: operations managers needed help automating data workflows. Reasonable and specific enough to test.
So, we ran the sprint — five interviews with ops managers. We heard about HubSpot, Salesforce, Google Sheets. And we heard this: "I'd rather deal with the inefficiency I know than risk configuring something wrong." Setup paralysis. Real pain, but not what we were looking for.
We ran a Listening Cycle after the sprint to pressure-test. The ops manager held up — but only just. And this other thread was showing up too: someone building things for themselves, not for a team. Creators. So we shifted the Bullseye hypothesis and tested it.
We found out that creators were interested in vibe coding, but interest isn't accountability. The signal we needed came from a group within the group — independent builders shipping production apps with real economic stakes. When things broke, they lost money. One said: "I can't trust the AI to auto-fix things. I need to understand what broke and why." That wasn't a feature request, that was a customer hypothesis in lights.
So we ran more Listening Cycles — drawing on Replay's existing customer base, developer relations (devrel) conversations, and patterns surfacing in their Discord — to triangulate before committing to each shift. Creator to builder, builder to builder at stakes, each cycle either sharpened the hypothesis or put it off to the side.
By the time Replay repositioned their landing page — moving from "anyone can build apps" to a tool built for builders with real consequences — the team wasn't guessing. We'd heard it across 4-5 cycles. Product decisions got easier, so did fundraising conversations. So did knowing what to build next.
The MCP and Chrome Extension aren't new ideas. They're what happens when you know exactly who you're building for.

When this makes sense
This sprint works if you:
- Have some idea of who you're building for (even if your team disagrees or you're uncertain)
- Have built a real product or have a clear problem you're solving
- Have a team of 3+ people who participate in customer or product decisions
- Have access to users, prospects, or churned customers you can interview
- Can commit two hours per week from your core team for about two mos — about 10 hours the week of the Bullseye Customer interviews
- Have the authority to stake a direction once the evidence is clear
Skip this if you've already validated your customer direction with recent interviews (last quarter) and can clearly explain who adopts first and why.

The alternative: Every week you're uncertain about your customer, you're burning time on misaligned work. For a team of 5, that's ~$40K/mo. For a team of 10, that's ~$80K/mo. Month after month compounds the cost — in payroll, in runway, in momentum.
With the sprint, you'll know who your Bullseye Customer is. Or who it isn't.
Your team is aligned. You can move.
Frequently asked questions (FAQ)
- Teams where leadership has already decided who the customer is and isn't genuinely open to evidence suggesting otherwise
- Teams with zero customer access and no warm network and no budget for recruiting
- Teams that can't commit 2-3 hours per week for two months — not counting interview week
If any of these apply, let's talk during our initial call — sometimes there's a modified path; sometimes this just isn't the right moment, and that's worth knowing early.
