CoSt

CoSt — The Growth Decision Engine

Most audits end with a list. CoSt ends with a decision.

CoSt (costdecision.com) is an AI-powered Growth Decision Engine built for founders, growth teams, and agencies who already have 40 findings on their desk and still have zero idea what to ship first. Instead of another 50-point recommendation list, CoSt delivers a single highest-leverage bet for the next 30 days — backed by live competitor data and paired with a Kill List proving why everything else lost.

What CoSt Does

Enter any website URL, pay via Stripe, and in about six minutes you receive:

A Primary Bet with a named hypothesis, three actions to ship this week, and an urgency score.

A Kill List — every alternative bet scored and rejected with a specific reason (speed, feasibility, impact, audience fit). No other audit tool on the market does this.

Evidence Strength breakdown across diagnosis alignment, competitive whitespace, ICP fit, and implementation speed.

"If Wrong" Downside Quantification — time, budget, and reversibility risk, so the decision to act takes seconds, not a committee.

Execution Assets (on the $499 tier): rewritten hero copy, ad variants, email subject + body, landing page copy, and a 3-tier budget allocation from $0 to $50k+.

What a Real Run Looks Like (Sample: GLP-1 Health App- https://myglp1.app)

To understand the depth of the engine, here is what CoSt delivered in a recent run for a health-tech startup:

Diagnosis: Found 20 conversion leaks and messaging failures, assigning a site health score of 5/10.

Opportunity Scoring: Evaluated 12 distinct growth bets. The winner scored 9.45/10: rewriting the hero section around a specific clinical stat ("40% of weight lost on GLP-1 is lean muscle"), with a projected +15–30% CTR lift.

The Kill List: Killed 3 tempting alternatives with hard evidence. A Content Hub was rejected (Speed score 2/10 — takes 3-6 months to rank);

Comparison SEO pages were killed (Speed score 4/10); a Doctor-shareable PDF was rejected (Feasibility score 4/10 — requires heavy engineering).

Execution & Testing: Delivered 6 ready-to-paste assets (ads, landing copy, outreach scripts) and designed a strict 7-day A/B test with a clear kill signal (≤3% lift = stop and pivot to the secondary bet).

Budget Allocation: Recommended the "Bootstrap" tier ($0–2k) to validate the messaging before scaling spend.

The 11-Stage Pipeline

Behind every run is an 11-stage pipeline: ICP + brand modeling, market analysis, competitive whitespace research (with live scraping of actual competitor sites, not LLM guesses), conversion diagnosis, opportunity scoring, bet selection, kill list generation, execution asset drafting, and a 90-day roadmap. If a bet carries medical, legal, or brand risks, the engine's validate_bet stage flags it for human REVIEW rather than auto-shipping.

What Sets CoSt Apart

Time: ~6 minutes vs. 4 weeks for a strategy consultant.

Price: $299 (Diagnosis) or $499 (Diagnosis + Execution) vs. $5,000–$15,000 for an agency engagement.

Output: One decision, not a 40-page deck you'll never re-read.

Honesty: Real sample reports are available at costdecision.com/sample — no email gate, no friction. Guarantee: "No Clarity, No Charge" — full refund within 48 hours if the Primary Bet doesn't give you clarity, or within 30 days if it doesn't move the agreed metric.

Who It's For

Founders post-audit: you just finished a CRO engagement, a consultant teardown, or a heatmap review and still don't know what to ship Monday.

Growth teams drowning in backlogs of "growth ideas" with no scoring framework.

Agencies via the $1,490 Agency Pack (5 runs, $298/client, 90-day validity) — delivering a $5k-level strategic verdict per client in minutes.

The Bottom Line

Consultants sell decks. Audit tools sell lists. CoSt sells the one thing most growth teams actually need: a decision. With the Kill List as its most defensible feature, CoSt doesn't just recommend what to do — it forces you to confront what to stop doing. That's the difference between a report you read once and a decision system you run every 30 days.
