## Scenario

Brainshelf is exploring a growth channel through newsletter creators who use read-later tools to curate content for their audiences. Analytics show that users who share three or more items per week from Brainshelf have a 3.4x higher 90-day retention rate [fictional] and generate an average of 2.1 referral signups per quarter [fictional]. The growth PM wants a brief marketing persona to shape acquisition messaging, partnership outreach, and a potential "Curator" tier positioning that targets newsletter creators who need a curation workflow, not just a reading inbox.

**Source Notes:**

- Substack creator-economy research documents that newsletter writers spend 30-40% of their creation time on content discovery and curation, establishing curation tools as workflow infrastructure.
- Readwise reader positioning case study shows that pivoting from "read later" to "read and curate" expanded their addressable market to include content creators, not just content consumers.
- ConvertKit creator survey data highlights that creators evaluate tools by workflow integration and export flexibility, not by feature count.

## Output

# Persona Dossier: Amara Osei, The Creator Who Curates Before She Writes (Marketing, Brief)

## Layer 1: Narrative Persona Dossier

## Executive summary
- Amara does not see Brainshelf as a reading app; she sees it as the first step in her content production pipeline.
- She evaluates curation tools by how well they export into her writing workflow, not by how well they display saved articles.
- Her purchase trigger is hitting a workflow ceiling: when her current tool cannot organize, annotate, and export fast enough for her publishing cadence.
- She distrusts tools that position themselves as "for everyone" because her needs are specific and she has outgrown general-purpose tools before.
- Creator-to-creator word of mouth is her primary discovery channel, not app store browsing or ads.
- She will pay for a tool that saves her two hours per week of curation labor, but she needs to see that savings in her own workflow before committing.
- Her sharing and referral behavior is organic: she shares tools that make her workflow visible to her audience.

### 1) Opening scene
Amara publishes a weekly newsletter on design leadership to 6,200 subscribers [fictional]. Every Sunday evening she opens her curation stack: Pocket for saves, a spreadsheet for tracking themes, and Apple Notes for draft annotations. She copies links between three tools, reformats annotations, and loses track of which articles she already covered. The curation step takes nearly as long as the writing.

She has heard about Brainshelf from two other creators and wonders if it could replace the spreadsheet and Pocket in one tool.

### 2) Who this person is under the surface
Amara is a design director who started her newsletter as a side project and grew it into a meaningful professional asset. She is not a full-time creator; she is a professional who creates. Her audience trusts her curation taste, which means every shared article reflects her judgment. She cannot afford to resurface irrelevant or dated content because it dilutes her editorial credibility.

### 3) How the buying story actually moves
Her evaluation is informal and self-directed. She hears about a tool from a peer, tries the free version for two to three publishing cycles, and converts only if the tool measurably reduces her curation-to-publish time. She does not compare feature lists; she compares the time from "save an interesting article" to "include it in this week's newsletter with context."

### 4) Trigger events that create urgency
- Trigger A: her curation process breaks during a high-output week and she misses a publishing deadline.
- Trigger B: a peer creator publicly credits a tool for improving their workflow, creating social proof with editorial credibility.
- Trigger C: her subscriber count crosses a threshold where curation quality directly affects growth metrics.

### 5) What they say vs what they mean
| What they say | What they mean | Messaging implication |
|---|---|---|
| "I need to see it in my workflow." | Feature demos are not enough; she needs to run a real publishing cycle. | Offer a trial tied to her publishing cadence, not a 14-day clock. |
| "Can I export with my notes?" | Data portability and annotation integrity are table stakes. | Lead with export quality and format flexibility. |
| "Pocket is fine for reading." | She already has a reading tool; she needs a curation tool. | Position as curation infrastructure, not a Pocket replacement. |

### 6) Operating modes
- Discovery mode: saving articles throughout the week from RSS, social, and peer recommendations.
- Curation mode: reviewing, annotating, and selecting articles for the next newsletter edition.
- Publishing mode: exporting curated items with annotations into her writing tool.

### 7) GTM strategy implications
Prioritize:
- "curation workflow" positioning over "read later" positioning
- creator-specific trial (measured by publishing cycles, not calendar days)
- export quality and annotation portability as headline differentiators
- creator partnership and guest-feature outreach as acquisition channels

Avoid:
- positioning as a general-purpose reading app (she already has one)
- feature comparison tables against Pocket or Instapaper (wrong competitive frame)
- aggressive trial-expiration messaging that clashes with her publishing cadence

### 8) Sales principles this persona forces
- Compete with the curation spreadsheet, not with Pocket.
- Let creators discover the tool through other creators, not through ads.
- Measure trial success by publishing-cycle integration, not by daily opens.

### 9) If this persona wins, what changes?
Brainshelf acquires a high-retention, high-referral user segment by positioning as curation infrastructure for newsletter creators. Growth experiments shift from broad acquisition to targeted creator partnerships, and the "Curator" tier finds a natural audience with measurable workflow value.

### E) Scenario tailoring

- For `release-notes`: frame curation improvements as workflow-time savings for creators, not feature inventory.
- For acquisition messaging: position Brainshelf as the tool that replaces the curation spreadsheet, not the tool that replaces Pocket.

### F) When not to use this persona
- Product UX decisions for casual consumer readers
- Enterprise procurement and team-level evaluation
- Freemium-to-paid conversion for non-creator users

### G) Assumptions and Confidence
- **Key assumptions:**
  - Newsletter creators are a high-retention, high-referral segment worth acquiring separately from general users.
  - Curation workflow positioning resonates more than read-later positioning for this audience.
  - Creator-to-creator word of mouth is the dominant discovery channel, not paid acquisition.
- **Confidence:** Medium
- **Confidence rationale:** Retention and referral data support segment value, but creator-specific acquisition funnel has not been instrumented and partnership channel ROI is untested.
