Bullseye Framework
Almost every failed startup has a product. What failed startups don't have are enough customers.
The Bullseye Framework is a systematic, three-phase process for discovering which marketing channel will actually drive growth for your startup. Created by Gabriel Weinberg and Justin Mares in 'Traction', it forces founders to brainstorm all 19 possible traction channels without bias, rank the most promising candidates, run cheap time-boxed experiments, and concentrate every resource on the single channel that wins. It replaces channel guessing — the default for most early-stage teams — with a repeatable, evidence-based prioritization system.
“We built a B2B SaaS tool that helps operations teams at mid-size companies automate their internal approval workflows. We're pre-launch, have about…”
Stop guessing which channel works — test all 19, own the one that scales
The Bullseye Framework begins with an exhaustive brainstorm across all 19 traction channels — from viral marketing and PR to engineering as marketing, community building, and offline events — ensuring no promising channel is dismissed by intuition alone. In the ranking phase, founders score each channel on three dimensions (cost to acquire customers, total reachable audience, realistic accessibility given current stage) and select the top 3–6 candidates for the middle ring. The focus phase runs cheap, time-boxed experiments on those candidates, collects real acquisition data, and identifies the single dominant channel — the inner ring — where all effort then concentrates. Two reinforcing principles govern the process: the 50% Rule (spend half your time on traction, not just product, even pre-launch) and the Critical Mass Principle (spreading across many channels at once dilutes impact; focus is what creates breakthroughs). When the dominant channel shows signs of saturation, the entire bullseye process restarts.
Most early-stage founders default to the channels they already know — or the ones that worked for a company they admire — without systematically evaluating whether those channels fit their product, audience, or stage. This produces the 'product in search of distribution' trap: a working product that never reaches critical mass because traction effort is scattered across too many channels or concentrated in the wrong one. The Bullseye Framework addresses this by making channel selection an empirical process, not a gut-feel decision.
You'll leave with a concrete, evidence-backed channel strategy: a bullseye diagram showing where every one of the 19 traction channels sits for your specific startup, and a testable experiment plan that tells you exactly what to run next — so you stop guessing and start acquiring.
- A description of your startup, product, and target customer
- A honest read on your current budget and team size
- Any channels you've already tried and what the results were
- Your current stage (pre-launch, early traction, scaling)
- A populated three-ring bullseye diagram with every channel assigned to outer, middle, or inner ring
- A scored, ranked shortlist of 3–6 candidate channels with rationale for each placement
- A concrete experiment plan for each middle-ring channel — specific test, success metric, timeline, and budget estimate
- A single recommended inner-ring channel to own, with a scaling path and saturation warning signs
Watch the methodology work.
Three specimens from a single real session: the same situation, unaided and calibrated, the full transcript, and the skill answering live in the channel where the work happens.
“You're six weeks from launch with a $3k/month budget, 15 design partners, and a mental list of seven channels you're vaguely planning to try simultaneously — LinkedIn ads, a blog, a Product Hunt launch, cold email, a partnership with a complementary tool, SEO, and maybe a podcast appearance. None have been tested; all feel reasonable. Every week you add one more channel to the list and make progress on none of them.”
“You've run the full bullseye. Thirteen channels are in the outer ring with explicit rationale for why they don't fit your stage. Three are in the middle ring with a two-week cheap experiment designed for each — specific tactic, success metric, and budget cap. One channel — direct outbound, which validated itself when you closed your design partners — is already in the inner ring, getting 80% of your traction effort. The bullseye diagram is on the wall. You know exactly what you're testing, why, and when to call it.”
The same skill, where the work happens.
No new app to learn. The methodology runs over the WhatsApp Business API, so the answer lands as a reply in the thread you’re already in — same rigour, zero context-switch.
What it does, specifically.
Each capability is a distinct move drawn straight from the source methodology — not a generic assistant guessing.
19-Channel Brainstorm
The skill walks you through all 19 traction channels in Weinberg and Mares's exhaustive taxonomy — from viral marketing and PR to engineering as marketing, existing platforms, and community building. For each channel, you answer four diagnostic questions: What would a campaign here look like? What would customer acquisition cost? How many customers are reachable? Is this channel accessible given your current stage and budget?
Bullseye Ring Assignment
After the brainstorm, the skill helps you sort every channel into one of three rings: outer (low potential right now), middle (worth a cheap test), or inner (the current dominant channel). Placement decisions are made explicit — you articulate why each channel lands where it does, which surfaces hidden assumptions and prevents premature elimination of promising options.
Channel Scoring Matrix
For each middle-ring candidate, the skill helps you score the channel on cost-to-acquire, audience size, and current feasibility — producing a ranked scoring matrix that makes trade-offs explicit and defensible. This step prevents the common failure mode where founders pick channels based on excitement rather than fit.
Cheap Experiment Design
For each ranked candidate, the skill designs a minimal, time-boxed test: a specific tactic, a binary or numeric success metric, a two-to-four-week timeline, and a budget ceiling. The goal is to gather real acquisition data — not build a full channel — so that the focus decision is grounded in evidence rather than projection.
Post-Test Focus Decision
Once experiment results are in, the skill analyzes outcomes against the pre-defined success criteria, identifies which channel has the highest scaling potential, and produces a focused inner-ring recommendation. It also flags signs of channel saturation — declining efficiency, rising CPAs, audience exhaustion — that signal when to restart the full bullseye process.

Bullseye Channel Diagram
A three-ring diagram with all 19 traction channels sorted into outer (deprioritized), middle (test candidates), and inner (current focus) rings — with a one-line rationale for each placement. This is your traction strategy on one page.
Channel Experiment Plan
A structured plan for each middle-ring channel: the specific test to run, the success metric, the timeline (typically 2–4 weeks), and the budget ceiling. Gives you a concrete action list you can hand to a co-founder or contractor.
Traction Channel Scorecard
A ranked scoring matrix of your top 3–6 candidate channels, scored on cost-to-acquire, reachable audience size, and current feasibility — with a composite score and the rationale behind each rating.
