In terms of when to stop and pivot: PART IV — ESCAPE VELOCITY
**Ch. 17 — Dropbox.** When networked products work, they *really* work — but Escape Velocity is furiously *sustaining* growth. Dropbox: IPO 2018 (NYSE: DBX) at $10B+; **fastest SaaS to $1B ARR**; 500M+ users in 8 years; launched April 2007 with a **4-minute self-narrated demo video** → beta waitlist 5,000 → 75,000 overnight (Reddit/HN/Digg). Classic "come for the tool, stay for the network" + a referral program giving storage. **[BIZBUILDER] Growth Team:** Dropbox built a cross-functional Growth & Monetization team (controversial in a product-driven culture). **HVA vs. LVA:…

In terms of when to stop and pivot: PART III — THE TIPPING POINT
**Ch. 11 — Tinder (Tipping Point).** The Tipping Point = a **repeatable strategy** to launch network after network. Tinder: 2B+ swipes/day, 1M dates/week, $1B+ revenue. Dating has naturally high churn (happy couples leave). **[SOCIAL][BIZBUILDER] The USC party tactic:** the team threw an incredible birthday party for a hyperconnected friend; to get in you had to download the Tinder app (bouncer checked) — highest one-day download spike, but what mattered was it being "**500 of the right people**" — the most social, hyperconnected people, on Tinder at the same time. **95% of…

In terms of when to stop and pivot: Quick-reference — named tactics and when they work/fail
| Tactic | Works when | Fails when | |---|---|---| | **Atomic network** | Pick the tiniest specific group at a specific time; build density | "Peanut-buttering" across a whole geography/industry | | **Solve a Hard Problem** | Product nails the hard side's unaddressed need (Tinder for women) | Hard side churns → degrades for everyone | | **Come for the Tool, Stay for the Network** | Tool + network tightly integrated (Dropbox folders) | Tool/network divergent → low conversion | | **Invite-Only** | Curated connected users invite connected users | Used purely for hype; or kills…

In terms of when to stop and pivot: Framework-as-Diagnostic Overlay
Greg's 7-tactic framework overlaid on Yuri's current infra: | Tactic | Greg's framework says | We have | Verdict | |---|---|---|---| | 1. MCP server as sales team | Publish to Smithery/MCPT/OpenTools for $0 CAC discovery | Zero — neither BizBuilder/KPDD nor Solacian have an MCP server | **REAL GAP** — but applicability depends on whether the product answers a queryable question; Solacian (Maze-dissolving AI) plausibly does, KPDD (PMF discovery) plausibly does | | 2. Programmatic SEO at 10K-page scale | Next.js + Firecrawl + AI content for "best X for Y" patterns | Zero pro…

In terms of when to stop and pivot: 1.1 Viral Hook Harvesting (Artemy method)
Source: [[knowledge/references/2026-03-20-data-driven-marketing-conf.md]] **When to use**: no creative team, small budget, need 30-50 testable creatives fast **Process**: 1. Search TikTok by niche keyword 2. Filter: 10K+ likes (minimum), prefer 50K+ 3. Download 30-50 videos (Facebook campaign limit = 50 creatives) 4. Test all raw in Meta: $3-5/day per creative, 3-5 days 5. Measure hook rate: ideal 50%, acceptable 22-26% 6. AI-rework top winners via Kling AI: generate 20-30 variations (not 1-3), vary gender, age, ethnicity, background, scenario (wild variations, not subtle…

In terms of when to stop and pivot: 1.2 Creative Kill Threshold (Kirill / Poisson method)
Source: [[knowledge/references/2026-03-20-data-driven-marketing-conf.md]] **When to use**: managing 10+ creatives with significant spend, need statistical kill rules **Process**: 1. Pull data: creative ID, date, spend, CPA (CSV) 2. Feed to Claude: "Apply Poisson distribution to identify optimal kill thresholds. Scatter plot spend vs CPA. Flag creatives I should kill." 3. Red line = 90% confidence kill threshold 4. View each creative as a trajectory (path over time), not a point **Benchmarks**: - Dataset reference: $2.5M spend, 1700 creatives, 8 months - Real waste exampl…
