description: "Diagnose and improve marketplace liquidity (match rate/fill rate, time-to-match, reliability) by segment. Produces a Marketplace Liquidity Management Pack: liquidity definition + metric tree, fragmentation map, segment scorecard, supply/demand bottleneck diagnosis, experiment backlog, measurement plan, and operating cadence. Use for Growth teams running two-sided marketplaces."

Marketplace Liquidity Management

Scope

Covers
- Defining liquidity as reliability: how often a user can complete the marketplace’s core action (find → match → transact) within an acceptable time and quality threshold
- Measuring liquidity where it actually happens (by “local markets” like geo × category × time window), not just in global averages
- Diagnosing liquidity failure modes: fragmentation, supply–demand imbalance (“flip-flop”), matching/mechanics issues, and quality/trust breakdowns
- Designing a practical liquidity operating system: scorecards, weekly review cadence, and a “whac-a-mole” rebalancing plan (move attention/inventory/incentives)
- Producing an actionable experiment backlog to improve liquidity (supply, demand, matching, pricing/incentives, trust & safety)

When to use
- “We need to improve marketplace liquidity / match rate / fill rate”
- “Time-to-match is too slow” / “buyers can’t find availability”
- “Supply and demand are imbalanced across cities/categories”
- “Our marketplace feels unreliable” / “conversion drops due to no availability”
- “We need a liquidity dashboard + operating cadence + experiments”

When NOT to use
- You don’t operate a two-sided marketplace (no matching between supply and demand).
- The primary problem is value proposition / ICP (use problem-definition or measuring-product-market-fit).
- You only need pricing changes (use a pricing strategy skill) without a liquidity diagnosis.
- You need a general growth plan unrelated to matching reliability (use designing-growth-loops / retention-engagement).

Inputs

Minimum required
- Marketplace type + sides (who are “buyers” and “sellers”)
- The core action you consider a successful outcome (e.g., request → booked; search → purchase; message → hire)
- Top 1–3 priority segments (geo/category/user cohort) and the time window you care about
- Best-available baseline metrics (even if rough): demand volume, supply availability, match/fill rate, time-to-match, cancellations/quality
- Constraints: budget, incentives you can/can’t use, policy/brand/trust, engineering capacity, timebox

Missing-info strategy
- Ask up to 5 questions from references/INTAKE.md, then proceed.
- If data is missing, proceed with explicit assumptions and label confidence.
- Do not request secrets or PII; prefer aggregated metrics or redacted examples.

Outputs (deliverables)

Produce a Marketplace Liquidity Management Pack (Markdown in-chat; or as files if requested) containing:

1) Context snapshot (goal, timebox, segments, constraints, decision this informs)
2) Liquidity definition + thresholds (reliability definition and “good enough” targets)
3) Liquidity metric tree (north-star + driver metrics, with event definitions)
4) Fragmentation map + segment scorecard (where liquidity is weak/strong; the “local markets” that matter)
5) Bottleneck diagnosis (supply vs demand vs matching/mechanics vs quality; include “flip-flop” state)
6) Intervention plan + prioritized experiment backlog (including reallocation/“whac-a-mole” plan)
7) Measurement + instrumentation plan (dashboards, alerts, tracking gaps)
8) Operating cadence (weekly liquidity review agenda + owners)
9) Risks / Open questions / Next steps (always included)

Workflow (7 steps)

1) Intake + define the decision and local market(s)

• Inputs: User context; references/INTAKE.md.
• Actions: Clarify the goal (metric + target + by when), define the core action, pick the “local market” unit (e.g., city × category × week), and decide the decision this work will inform (what you’ll do differently).
• Outputs: Context snapshot + local market definition.
• Checks: A stakeholder can answer: “Which segment(s) improve by how much, by when, and what will we change based on the result?”

2) Define liquidity as reliability + set thresholds

• Inputs: Core action, time sensitivity, quality constraints (cancellations, refunds, etc.).
• Actions: Define liquidity as the probability of success within thresholds (time-to-match, quality). Choose 1 north-star liquidity metric and 3–6 drivers (fill rate/match rate, time-to-match, availability, acceptance, cancellation).
• Outputs: Liquidity definition + “good enough” targets + metric tree outline.
• Checks: The definition is measurable, segmentable, and aligned to the user’s experience (“reliability”).

3) Build a segment scorecard + diagnose fragmentation

• Inputs: Baseline data by geo/category/time window (best available).
• Actions: Create a segment scorecard for each local market: demand, supply, matching, and quality metrics. Identify fragmentation (thin markets, long tail categories, uneven geo distribution) and “uniform needs” vs heterogeneous needs.
• Outputs: Fragmentation map + ranked list of worst segments (where liquidity blocks growth).
• Checks: The scorecard avoids global averages and includes enough volume to be meaningful (or flags low-confidence segments).

4) Diagnose bottlenecks (flip-flop + mechanics + quality)

• Inputs: Segment scorecard; any qualitative evidence (support tickets, user feedback, ops notes).
• Actions: For each priority segment, label the primary failure mode:
• Supply-limited (not enough availability/inventory)
• Demand-limited (not enough intent/requests)
• Matching/mechanics-limited (ranking, discovery, response time, pricing friction)
• Quality/trust-limited (cancellations, no-shows, fraud, low ratings)
  Also check for the “flip-flop” dynamic (which side is currently the constraint) and the graduation problem (top suppliers leaving).
• Outputs: Bottleneck diagnosis per segment + evidence notes.
• Checks: Each diagnosis includes at least 1 metric signal and 1 plausible causal story you can test.

5) Generate interventions + experiment backlog (including reallocation)

• Inputs: Bottleneck diagnosis; constraints; available levers.
• Actions: Create intervention options for each bottleneck type (supply, demand, mechanics, quality). Include a “whac-a-mole” plan: how you will reallocate attention/inventory/incentives across segments weekly. Convert interventions into experiments with clear hypotheses and success metrics.
• Outputs: Prioritized experiment backlog + reallocation playbook.
• Checks: Every experiment has (a) a segment, (b) a primary metric, (c) a target effect size or directional expectation, and (d) a plausible cycle time.

6) Design measurement + liquidity operating cadence

• Inputs: Chosen metrics and experiments.
• Actions: Specify dashboards/alerts, event definitions, and instrumentation gaps. Create a weekly liquidity review agenda and decision log (what gets rebalanced, what gets shut down, what gets scaled).
• Outputs: Measurement plan + operating cadence (owners if known).
• Checks: Each key metric is tied to a data source and update frequency; the cadence produces concrete decisions, not status updates.

7) Quality gate + finalize the pack

• Inputs: Draft pack; references/CHECKLISTS.md and references/RUBRIC.md.
• Actions: Run the checklist and score with the rubric. Tighten the pack until it is specific, segment-aware, and testable. Always include Risks / Open questions / Next steps.
• Outputs: Final Marketplace Liquidity Management Pack.
• Checks: The next 2 weeks of work are unblocked (data pulls, 1–3 experiments, cadence).

Quality gate (required)

• Use references/CHECKLISTS.md and references/RUBRIC.md.
• Always include: Risks, Open questions, Next steps.

Examples

Example 1 (services marketplace, geo fragmentation):
“Use marketplace-liquidity. We run a home cleaning marketplace across 12 cities. Goal: increase booking fill rate from 62% → 80% in 8 weeks in our bottom 4 cities. We suspect supply is thin and response times are slow. Output a Marketplace Liquidity Management Pack with a segment scorecard, bottleneck diagnosis, and a prioritized experiment backlog.”

Example 2 (B2B marketplace, category imbalance):
“Use marketplace-liquidity. We match startups with freelance designers. Liquidity is strong in ‘logo design’ but weak in ‘product design’ and ‘brand refresh.’ Goal: cut median time-to-first-qualified-match from 5 days to 2 days for product design in 60 days. Provide a liquidity metric tree, fragmentation map, and operating cadence.”

Boundary example (not a liquidity problem):
“Write Google Ads copy to get more buyers.”
Response: this is primarily acquisition/copy. If marketplace reliability is already strong, use copywriting / channel-specific growth work. If reliability is unknown, start with an intake to confirm a liquidity bottleneck first.
