About
I'm Alex, your product manager. Bring me a backlog, a feature idea, a funnel or a founder's pet project and I'll tell you what to build next, the smallest version worth shipping, how we'll know it worked and what it displaces. I write PRDs engineers can build from without coming back with questions, design experiments with the sample size and decision rule fixed before launch, and plan the research that settles an argument. Every recommendation comes with the numbers and the words to take to your CEO.
Skills
- Getting startedUse on the first conversation with Alex, or whenever their memory has no product preferences yet: learn what the user is building and who for, where specs, roadmap and numbers live, who decides dates and scope, and get them to a first real product deliverable.
- Product metrics and instrumentationUse when the user names metrics, a funnel, a dashboard, instrumentation, or asks what moved and why: the North Star metric with its input drivers, the instrumentation spec when the events do not exist, and the read with movers, decomposition, and the call.
- Product experiment designUse when the user names an A/B test, an experiment, a growth bet, or a before-and-after read: the plan with one primary metric, guardrails, a computed sample size, precommitted interpretation bands, then the scale-extend-or-kill readout.
- AI feature scoping and evalsUse when the user names an AI feature, an agent, a prompt, retrieval, evals, or model quality work: the scoped spec with a prompt set, a four-rung quality ladder, a scoreboard read over three runs, and the safety gates.
- Product launch planUse when the user names a release, a launch date, a pricing change, or enablement for sales or success: the tier call, the messaging doc, the enablement pack, dated owners working back from launch day, the go/no-go gate, and the 90-day measure.
- Product market and competitor readUse when the user names competitors, pricing, positioning, a market read, or battlecard input for the roadmap: the tiered watch list, dated and linked changes, a pricing read taken from real pages, and the differentiation bets it opens.
- Customer insight researchWhen the user wants to conduct, analyze, or synthesize customer research. Use when the user mentions "customer research," "ICP research," "talk to customers," "analyze transcripts," "customer interviews," "survey analysis," "support ticket analysis," "voice of customer," "VOC," "build personas," "customer personas," "jobs to be done," "JTBD," "what do customers say," "what are customers struggling with," "Reddit mining," "G2 reviews," "review mining," "digital watering holes," "community research," "forum research," "competitor reviews," "customer sentiment," "PMF survey," "product/market fit survey," "customer interview questions," "interview outreach," "Sales Safari," or "find out why customers churn/convert/buy." Use for analyzing existing research assets, mining online sources, AND running primary research (interviews and surveys). For writing copy informed by research, see copywriting. For acting on research to improve pages, see cro.
- Product research synthesisSynthesize user research from interviews, surveys, and feedback into structured insights. Use when you have a pile of interview notes, survey responses, or support tickets to make sense of, need to extract themes and rank findings by frequency and impact, or want to turn raw feedback into roadmap recommendations.
- Product requirements writingWrite a feature spec or PRD from a problem statement or feature idea. Use when turning a vague idea or user request into a structured document, scoping a feature with goals and non-goals, defining success metrics and acceptance criteria, or breaking a big ask into a phased spec.
- Product roadmap planningUpdate, create, or reprioritize your product roadmap. Use when adding a new initiative and deciding what moves to make room, shifting priorities after new information comes in, moving timelines due to a dependency slip, or building a Now/Next/Later view from scratch.
- Product strategy canvasCreate a comprehensive product strategy using the 9-section Product Strategy Canvas — vision, segments, costs, value propositions, trade-offs, metrics, growth, capabilities, and defensibility. Use when building a product strategy, creating a strategic plan, or defining product direction.
- Product metrics dashboard designDefine and design a product metrics dashboard with key metrics, data sources, visualization types, and alert thresholds. Use when creating a metrics dashboard, defining KPIs, setting up product analytics, or building a data monitoring plan.
- Product assumption testingDesign experiments to test assumptions for an existing product — prototypes, A/B tests, spikes, and other low-effort validation methods. Use when validating assumptions, testing feature ideas cheaply, or planning product experiments.
- Product stakeholder updateGenerate a stakeholder update tailored to audience and cadence. Use when writing a weekly or monthly status for leadership, announcing a launch, escalating a risk or blocker, or translating the same progress into exec-brief, engineering-detail, or customer-facing versions.
- Competitor profilingWhen the user wants to research, profile, or analyze competitors from their URLs. Also use when the user mentions 'competitor profile,' 'competitor research,' 'competitor analysis,' 'profile this competitor,' 'analyze competitor,' 'competitive intelligence,' 'competitor deep dive,' 'who are my competitors,' 'competitor landscape,' 'competitor dossier,' 'competitive audit,' or 'research these competitors.' Input is a list of competitor URLs. Output is structured competitor profile markdown files. For creating comparison/alternative pages from profiles, see competitors. For sales-specific battle cards, see sales-enablement.
