Startup Traction Strategy by Phase

When to Use

The startup is somewhere on the growth curve and needs a phase-appropriate traction strategy. Use this skill when:

• The founder can't tell if they have product-market fit yet
• Growth has plateaued and the channels that worked before aren't working now
• The founder is spending 90%+ of their time on product
• A pivot is being considered
• The user asks "what should we focus on for growth right now?"

Context & Input Gathering

Required Context (must have — ask if missing)

• Current metrics: users, revenue, growth rate (even rough)

→ Check prompt for: numeric counts, percentages, trends → If missing, ask: "What are your current metrics? Rough numbers are fine — users, paying customers, monthly growth."

• Time allocation: how the founder/team is currently splitting effort

→ Check prompt for: "spending X% on", "we focus on", "most of our time" → If missing, ask: "Roughly how is your week split between product work and getting customers?"

• Current traction activities: what's actively being tried

→ Check prompt for: "we do X for growth", channel names → If missing, ask: "What are you doing right now to get new customers?"

Observable Context

• Product maturity: MVP, v1, v2+
• Team size and composition
• How customers currently describe the product (satisfaction signals)

Default Assumptions

• If user count is under 1,000 and no clear growth rate exists → assume Phase I
• If rough product-market fit signals exist (paying customers, word-of-mouth, retention) → Phase II
• If established business model with consistent growth → Phase III

Sufficiency Threshold

SUFFICIENT: metrics + time allocation + current activities known
PROCEED WITH DEFAULTS: metrics known; assume time is 90/10 product/traction (the common failure mode)
MUST ASK: metrics are completely unknown (can't diagnose phase)

Process

Use TodoWrite:

• [ ] Step 1: Diagnose phase
• [ ] Step 2: Audit time allocation against 50% Rule
• [ ] Step 3: Map phase-appropriate channels
• [ ] Step 4: Apply the moving-the-needle filter
• [ ] Step 5: Produce phase strategy document

Step 1: Diagnose Phase (I / II / III)

ACTION: Classify the startup into one of three phases based on observable signals:

• Phase I — Making something people want. No product-market fit yet. Signals: low user count, high churn, constant product revision, customers don't obviously stick. The core job is building a product worth marketing.
• Phase II — Marketing something people want. Product-market fit established. Signals: customers stick, grow by word of mouth, revenue or engagement climbs. The core job is building a sustainable customer-acquisition engine.
• Phase III — Scaling the business. Business model established, market position significant. Signals: consistent growth rate, unit economics work, the question is how to dominate the market. The core job is scaling proven channels.

Write the diagnosis with one paragraph of evidence to phase-diagnosis.md.

WHY: Every downstream decision depends on phase. A Phase I startup doing Phase III tactics (mass advertising, PR campaigns, full sales teams) wastes money on channels that can't compound without a sticky product. A Phase III startup doing Phase I tactics (personal outreach, hand-holding each customer) underuses scale. Phase mismatch is the most common strategy error.

IF signals are mixed between Phase I and II → default to the earlier phase. The cost of over-investing in traction before fit is higher than the cost of under-investing briefly after fit.

Step 2: Audit Time Allocation Against the 50% Rule

ACTION: Calculate how the founder/team is actually splitting time between product work and traction work. Compare to the 50% Rule: 50% of time on product, 50% on traction — at all times, in parallel, regardless of phase.

If the split is 90/10 product/traction (the common default), name it explicitly. Quote the Product Trap warning: the #1 reason investors pass on otherwise-good founders is focus on product to the exclusion of everything else.

WHY: Most founders wildly over-invest in product. Marc Andreessen: "Almost every failed startup has a product. What failed startups don't have are enough customers." The Product Trap is the belief that "if we build it, they will come." Without explicit time-budget accountability, traction work gets crowded out by product work that always feels more urgent. The 50% Rule is a forcing function, not a guideline.

IF the user resists 50/50 because "the product isn't ready" → that's exactly when you need traction experiments, because channel feedback shapes the product. IF the user is 50/50 already → excellent, skip to Step 3.

Step 3: Map Phase-Appropriate Channels

ACTION: Based on the diagnosed phase, list which channels typically work and which typically don't. Use the mapping in references/phase-channel-fit.md.

Flag any current channel that's mismatched with the phase. Common mismatches:

• Phase I startup running SEM ads without product-market fit → burning budget on churning users
• Phase II startup still relying only on personal outreach → hitting volume ceiling
• Phase III startup ignoring PR → missing biggest growth lever

WHY: Channels have phase fit. "Some traction channels will move the needle early on but fail to work later. Others are hard to get working in Phase I but are major sources of traction in the later phases." Running a Phase I playbook in Phase II means growth stalls. Running a Phase III playbook in Phase I means spending on customers you can't retain. Matching phase to channel is the core of the book's strategy advice.

Step 4: Apply the Moving-the-Needle Filter

ACTION: For each proposed or current traction activity, ask: "Can this plausibly deliver enough new customers to meaningfully advance our traction goal at our current scale?"

Do a back-of-envelope calculation: (target new customers) ÷ (realistic conversion rate, 1-5%) = audience you need to reach. Compare that to the channel's realistic reach. If the math doesn't work, the activity is off the needle.

Phase I needle ≠ Phase III needle:

• In Phase I, a tweet from a respected person or a speech to 300 people *can* move the needle.
• In Phase III, if you have 10,000 visitors/day, a blog post that sends 200 visitors is noise.

WHY: Founders waste time on activities that feel productive but can't meaningfully affect growth. The moving-the-needle filter is a math check: does the channel even have the volume to matter? Running a Facebook ad with $100 budget in Phase III is not a test — it's rounding error.

IF an activity can't pass the needle filter → cut it. Put the time back into the 50% traction budget.

Step 5: Produce the Phase Strategy Document

ACTION: Write phase-strategy.md containing:

1. Phase diagnosis with evidence
2. Current time allocation vs 50% Rule (and the correction needed)
3. Phase-appropriate channels — which to pursue, which to cut
4. Moving-the-needle audit — activities cut, activities kept
5. Next 4 weeks of traction experiments, sized to the phase

WHY: A written strategy is a forcing function for accountability. "We're Phase I and the 50% Rule says we need more unscalable outreach" is easier to hold the team to than a verbal agreement. The document also makes phase transitions legible — in 3 months, re-read it and ask "what phase are we in now?"

Inputs

• Startup metrics (users, revenue, growth rate)
• Current time allocation (product vs traction)
• Current traction activities
• Traction goal (if user has one)

Outputs

Three markdown files:

1. phase-diagnosis.md — Phase (I/II/III) with evidence
2. phase-strategy.md — Complete strategy with time allocation correction and channel map
3. weekly-traction-plan.md — Next 4 weeks of phase-appropriate experiments

Key Principles

• Phase determines everything. A channel that's a hit in Phase II can be a disaster in Phase I. WHY: The same tactic at the wrong time is a waste. Speed and volume needs change dramatically across phases — Phase I rewards unscalable tactics, Phase III punishes them.

• 50/50 is non-negotiable. Not 80/20 in favor of product "because we're early". Not 20/80 "because we need customers fast". Always 50/50. WHY: Product and traction co-evolve. Traction experiments reveal what customers actually want. Product changes shape what traction channels work. Decoupling them is how startups die with "a great product nobody wanted."

• The Product Trap has a specific detection signal. If the founder says "the product isn't ready for marketing yet", that's the trap. WHY: The product is never "ready." Marc Andreessen: "The number one reason we pass on entrepreneurs is focusing on product to the exclusion of everything else." Ready for marketing means ready for feedback, not ready for perfection.

• Re-diagnose phase quarterly. Phases aren't permanent. What was Phase I six months ago might be Phase II now. WHY: Phase transitions are easy to miss from the inside. The channels that served you in Phase I will saturate as you enter Phase II. If you don't re-diagnose, you'll keep running Phase I tactics and watch growth flatten.

• **Unscalable tactics are a Phase I *strategy*, not a failure mode.** Paul Graham's "do things that don't scale" is phase-specific advice. In Phase I, it's correct. In Phase III, it's a trap. WHY: The same advice applied in the wrong phase produces opposite outcomes. Don't let "unscalable = bad" reflexes push you to premature scaling in Phase I.

Examples

Scenario: "We're 3 months in, 200 users, growth has stalled"

Trigger: "Built a note-taking app for lawyers. 200 users in 3 months, mostly from Twitter. Growth has stalled the last 4 weeks. Only I'm doing marketing; 2 engineers on product."

Process: (1) Diagnose Phase I — low user count, no repeat customer signals, team still iterating product. (2) Time audit: founder estimates 70% product, 30% traction → flag the gap. Apply 50% Rule → founder needs to reclaim 20% of product time for traction. (3) Phase-appropriate channels: unscalable tactics work best here — targeting blogs (legal industry blogs), speaking at small legal conferences, direct outreach to named lawyers. Cut: any paid ads (wrong phase), no SEO (too slow for Phase I). (4) Moving-the-needle filter: founder was about to run $500 Facebook ads — kill that. $500 goes to sponsoring a legal-industry newsletter instead. (5) Produce 4-week plan: 10 cold emails/week to named lawyers, 1 guest post on a legal blog, outreach to 2 legal podcast hosts.

Output: Clear Phase I diagnosis, Product Trap flagged (70/30 instead of 50/50), and a concrete unscalable-first plan.

Scenario: "Great growth for 18 months, now slowing"

Trigger: "B2B SaaS, $200k MRR, 30% YoY growth. Content marketing drove most of our growth. Last 3 months growth has flattened to 5%. What's happening?"

Process: (1) Diagnose: likely Phase II → Phase III transition. Product-market fit clearly there. Content marketing is saturating (the Law of Shitty Click-Throughs). (2) Time audit: 50/50 seems maintained — that's good. (3) Phase-appropriate channels: Phase III should leverage channels with bigger volume ceilings. Consider PR (first big feature), paid ads at scale, BD with integration partners. (4) Moving-the-needle filter: a new blog post that sends 500 visitors no longer moves the needle at this scale. (5) Produce plan: kick off PR push (3 pitches to industry media), add SEM for bottom-funnel keywords, negotiate 2 integration partnerships.

Output: Phase II→III transition identified; next-phase channels selected; content remains but isn't the growth engine anymore.

Scenario: The classic Product Trap

Trigger: "We've been building for 8 months, launching soon, want to plan a big marketing push for launch day."

Process: (1) Diagnose Phase I — not launched, no customers. (2) Time audit: user says "we haven't done marketing yet because the product isn't ready" → Product Trap diagnosis, quote Andreessen. (3) 50% Rule applied retroactively — what traction experiments should have been running for the last 8 months? At minimum: building an email list, talking to 20 prospective customers weekly, finding 10 blogs where the audience lives. (4) Moving-the-needle: a "big launch day push" without a list or audience is a guaranteed flop. (5) Strategy: delay launch by 4 weeks, spend those weeks building traction groundwork (email list, blog relationships, 20 customer conversations), so launch lands on an audience that already cares.

Output: Product Trap named and corrected; launch plan now has traction preamble; founder understands the rule going forward.
