# Product Roadmap: Personal Briefing Feed **Date:** 2026-02-21 **Owner:** Product track (knowledge workers + consumers) **Status:** Draft for execution --- ## Vision Ship a daily briefing product that helps users identify what matters now, adapt the feed instantly with lightweight feedback, and trust the results enough to return habitually. ## Product Thesis People do not need another infinite feed. They need a controllable, high-signal briefing that respects time, explains relevance, and improves immediately from feedback. --- ## Milestone Summary | # | Name | Proves | Depends On | |---|------|--------|------------| | P0 | Beachhead Validation | Users care enough to return for a daily briefing | M0 + partial M1 | | P1 | Concierge Alpha | Briefing usefulness and immediate adaptation in a narrow segment | M1 + partial M2 | | PG1 | Personalization Core Done (Blocking Gate) | Core personalization loop is correct, immediate, and meaningfully better than baseline | P1 + M1/M2/M3 core slices | | P2 | Productized Beta | Self-serve onboarding, trust UX, and repeatability without manual curation | M2 + partial M3 | | P3 | Public Launch | Reliability, quality floor, and trust controls at public volume | M3 + M5 core + M6 partial | | P4 | Scale + Revenue Fit | Sustainable growth and monetization without quality collapse | M6 + M7 | --- ## Current Status | Phase | Status | |-------|--------| | p0: Beachhead Validation | NOT STARTED | | p1: Concierge Alpha | NOT STARTED | | pg1: Personalization Core Done gate | NOT STARTED | | p2: Productized Beta | NOT STARTED | | p3: Public Launch | NOT STARTED | | p4: Scale + Revenue Fit | NOT STARTED | **Current phase:** p0 (Beachhead Validation) --- ## Milestone P0: Beachhead Validation ### Milestone Thesis Validate that a personal briefing feed solves a painful daily job for target users and creates early repeat usage. ### Done When - 20-50 users recruited in target segment. - Daily briefing prototype used for 2+ weeks. - Median user gives at least one feedback action per session. - Interview evidence confirms value over baseline feeds. - D2 and D7 retention meet agreed threshold. ### Phase Plan - Phase 1: Target Segment and Research Ops - Phase 2: Concierge Briefing Loop - Phase 3: Signal and Retention Evaluation --- ## Milestone P1: Concierge Alpha ### Milestone Thesis Deliver a high-value daily `Today Brief` with transparent reasons and immediate feedback reflection for a narrow cohort. ### Done When - Ranked briefing cards with source links and reason labels are live. - `more/less/hide/mute/save` controls are available and used. - Next refresh visibly reflects negative feedback. - Time-budget mode (`5/10/20`) is used by pilot users. - Weekly active usage indicates repeated utility. ### Phase Plan - Phase 1: Briefing UX and Reason Labels - Phase 2: Feedback Controls and Real-Time Adaptation - Phase 3: Quality and Diversity Guardrails --- ## Milestone P2: Productized Beta ### Milestone Thesis Turn concierge alpha into a self-serve product with stable onboarding and trust-preserving defaults. ### Done When - Onboarding can be completed in under 3 minutes. - Cohort layer (`trending for people like you`) is available. - Explanations are clear and consistent per card. - D7 retention and useful-item rate beat baseline. - Manual curation is no longer required for normal operation. ### Blocking Prerequisite P2 cannot start until **PG1 Personalization Core Done** passes. ### Phase Plan - Phase 1: Self-Serve Onboarding and Profile Bootstrapping - Phase 2: Cohort and Context Views - Phase 3: Trust Controls and Preference Persistence --- ## Milestone P3: Public Launch ### Milestone Thesis Launch publicly with reliability and trust controls suitable for broader consumer and knowledge-worker usage. ### Done When - Reliability and latency SLOs for briefing generation are met. - Freshness, duplicate suppression, and source quality floor are enforced. - Notification cadence controls prevent fatigue. - Product support and incident playbook are active. ### Phase Plan - Phase 1: Reliability and SLO Enforcement - Phase 2: Operational Quality Controls - Phase 3: Launch Readiness and Support Ops --- ## Milestone P4: Scale + Revenue Fit ### Milestone Thesis Scale the product and validate monetization while preserving user trust and briefing quality. ### Done When - Monetization model validated. - Revenue and quality metrics monitored together. - Retention remains stable as volume increases. - Next segment expansion is backed by product data. ### Phase Plan - Phase 1: Monetization Experiments - Phase 2: Quality-Protecting Growth - Phase 3: Expansion Strategy --- ## Milestone PG1: Personalization Core Done (Blocking Gate) ### Milestone Thesis Before expanding product breadth, prove the personalization loop is technically correct, immediately responsive, and materially useful to users. ### Must Pass (All Required) - **Hard negatives are exact:** `hide/mute/block` items and creators never leak after write, restart, or replay. - **Immediate adaptation is real:** `more/less/skip/save` actions change next-refresh ranking within target latency budget. - **Replay correctness:** user personalization state (seen-state, preference shifts, relationship weights) rebuilds deterministically from checkpoint + WAL replay. - **Quality uplift vs baseline:** useful-item rate and repeated-unwanted-item rate beat a non-personalized baseline feed. - **Diversity with personalization:** relevance holds while source/topic domination stays within guardrails. ### Why This Gate Exists Without this gate, roadmap execution drifts into breadth (more surfaces, more modes) before the core personalization promise is trustworthy. --- ## Product Metrics ### Activation - First briefing completion rate - Time to first useful item saved - Feedback action rate in first session ### Retention - D1/D7/D30 retention - Sessions per active user per week - Percentage of users with 4+ briefing days per week ### Quality and Trust - Useful-item rate per briefing - Repeated-unwanted-item rate after negative feedback - Diversity score in top 10 items - Explanation usefulness rating --- ## Dependencies on Engine Track | Product Capability | Primary Engine Dependencies | |--------------------|-----------------------------| | Real-time adaptation from feedback | M1 Signal Engine, M3 Feedback Loop | | Cohort briefing layer | M3 User model, M6 cohort surface support | | Search-within-briefing | M5 Hybrid Search | | Public reliability | M7 Production Hardening | --- ## Planning References -
