What It Is

jtgreene.com is Jeffrey Greene’s Growth Analytics Portfolio. It is positioned not as a standard marketing or SEO SaaS product, but as a personal portfolio for growth analytics work. The site’s core message is that the author uses SQL, Python, Tableau, Power BI, and some R to turn customer and performance data into actionable growth decisions, covering experimentation, segmentation, lifecycle/CRM, ROI, profitability, and KPI governance.

Core Features and Use Cases

Based on the main content, the portfolio emphasizes “defining the business decision and primary KPI first, then building the data foundation.” Featured cases include Channel Truth Dashboard and Churn Early Warning System. The former aims to standardize channel taxonomy, connect spend with revenue, and support budget decisions using 7-day last non-direct attribution, MER/ROAS, CAC, and 60–90 day customer quality; however, the project is still marked as in development for Q3 2026. The latter focuses on churn early warning, using features such as recency, frequency, monetary value, and discount behavior to produce risk scores and weekly retention action lists, while measuring retention lift, save rate, cost per save, and incremental profit through a holdout group.

Data, Platforms, and Integrations

The site does not disclose specific data scale, real customer counts, or data source volume. Supported platforms are presented more as the author’s skill stack and delivery formats: SQL for datasets, Python/R for analysis, Power BI/Tableau for dashboards, plus notebooks, SQL snippets, PDF executive summaries, playbooks, and decision briefs. The text does not list formal integrations with Google Ads, Meta, GA4, CRM systems, or data warehouses.

Pricing and Support

The main content does not mention pricing, plans, payment methods, or free trials, nor does it define any support SLA. Since this is a personal portfolio, its commercial purpose is more likely recruitment, project collaboration, or consulting leads rather than a self-serve software product.

Pros, Cons, and Who It’s For

Its strengths are a mature methodology and a clear emphasis on KPIs, guardrails, QA, operating cadence, and deliverable outputs, making it useful for growth, marketing analytics, CRM, and retention teams. The drawbacks are that some cases are still under development, several links appear to be pending, and there is a lack of real data scale or external validation. It is suitable for recruiters evaluating growth/marketing/data analytics candidates, and also for teams looking for references on how to design channel attribution and churn early warning projects.

Access from China and Alternatives

Access from mainland China cannot be determined from the text alone and should be treated as unknown; payment methods are also not disclosed. For productized alternatives, consider Power BI, Tableau, Looker Studio, GA4, Mixpanel, Amplitude, or local growth analytics consultants and dashboard-building services.
