Voice
Third-person positioning voice. Modeled on the credential-forward "Why?"
blurbs Sequoia / curated job platforms generate for founders and engineers.
Compresses real proof points into sentence fragments that earn the reader's
attention without sounding like a cover letter.
Scope: self-positioning only. Bios, blurbs, headlines, openers, About sections.
- For social posts in the subject's voice ->
social-draft
- For generic marketing copy ->
copywriting
Source of Truth (read every time)
Before writing anything, load the subject's source-of-truth files (their wiki,
profile doc, resume, and any past public bios). Never invent a fact, company,
metric, or title. If the proof isn't there, ask or use a different angle.
| File |
What it has |
USER.md (or equivalent) |
Identity, current work, strengths, key people |
career-profile.md (if any) |
Positioning, target roles, differentiators |
resume.md (if any) |
Companies, dates, bullets, metrics, publications |
If any of these are stale or missing, surface the gap before writing.
The Core Pattern (Why? blurb)
[CREDENTIAL NOUN] [optional CONTEXT TAG] with [PROOF NOUNS]
Examples (real Sequoia recruiting feed shapes, swap the proof nouns to fit
the subject):
- "Founding engineer with full-stack and AI infrastructure proven"
- "Founding engineer at ideal YC company with agentic expertise"
- "Princeton CS founding engineer with infrastructure and systems experience"
- "Bloomberg + AWS engineer with 0-to-1 shipping and full-stack capabilities"
Anatomy:
- Credential noun (lead):
Founding engineer, Princeton CS founding engineer, YC founding engineer, Bloomberg + AWS engineer, Agent infrastructure engineer. Strongest single noun phrase first.
- Context tag (optional):
at YC AI company, at agent infrastructure startup. Only add when it sharpens the fit for the audience.
- Proof nouns (the differentiation): comma- or
and-joined nouns derived from real shipped work. agentic expertise, 0-to-1 shipping, multi-tenant auth, MCP-powered SDK, customer delivery experience.
- Length: 10-22 words.
- Person: third-person fragment. No "I", no verb-led sentence.

Voice Rules
Lead with the strongest single credential. "Founding engineer at $COMPANY
(YC S25)" beats "20-year-old undergrad". Audience-relevant noun first.
Specificity > superlative. multi-tenant auth + microVM sandboxes beats
world-class infrastructure work. Numbers from the resume are fair game
(85% doc analysis reduction, 4.6x relevance gain, $32k raised).
Proof must trace to a real shipped thing. If you can't cite the resume
bullet or wiki page that produced the claim, rewrite the claim.
One angle per blurb. Don't try to land founding engineer + research +
design + nonprofit in one sentence. Pick the one the audience cares about.
Stack-rank credentials by audience:
| Audience |
Lead with |
| YC / agent startups |
Founding engineer at $COMPANY (YC S25) -> agent / infra / auth proof |
| Big tech intern recruiting |
$SCHOOL CS '$YEAR -> internship proof, then current role |
| Research labs |
$SCHOOL CS researcher with $ADVISOR -> publications |
| Design-engineering roles |
Frontend-tasted full-stack engineer -> motion / 3D / design system proof |
| Founders / partners |
YC founding engineer at $AGE -> 0-to-1, distribution proof |
Anti-Patterns (cut on sight)
Generic AI-application voice:
- "passionate about", "driven by", "thrilled to", "humbled to"
- "results-oriented", "self-starter", "team player", "fast learner"
- "leveraging", "synergy", "ecosystem", "unlock", "game-changer"
- "I am a Computer Science student at $SCHOOL interested in..." (every CS undergrad on the planet)
- Vague proof: "experience with AI", "worked on infrastructure", "built systems"
- Fluffy openings: "As a founding engineer..." (just say founding engineer)
- Three-adjective stacks: "fast, scalable, reliable"
- Hedges: "some experience with", "exposure to", "familiar with"
If a sentence could describe any $SCHOOL CS junior, rewrite it until it can
only describe the subject.
AI writing tells (hard cut)
Two patterns are signature AI writing tells. They make a blurb read as
machine-generated even when the proof is real. Cut both on sight.
- No em dashes (
- long-form, --). Use periods, commas, colons, or
parentheses. The em dash creates the AI rhythm "X, and here's why, Y."
Bios in this voice are fragment-style; periods do the work.
- No negative parallelism. Cut: "Not just X, but Y." / "It's not X, it's
Y." / "X isn't the goal. Y is." Make the positive claim directly. The
Why? blurb pattern is
[CREDENTIAL NOUN] with [PROOF NOUNS], not a
rhetorical contrast.
Bad: "Not just a CS student, but a founding engineer at $COMPANY (YC S25)."
Good: "CS founding engineer at $COMPANY (YC S25)."
Bad: "Founding engineer at $COMPANY (YC S25) -- shipping MCP-powered SDK and microVM auth."
Good: "Founding engineer at $COMPANY (YC S25) shipping MCP-powered SDK and microVM auth."
Workflow
- Identify the surface. What is being written, who reads it, what action do they take after.
- Pick the audience-stack-rank credential. From the table above.
- Pull 1-3 proof nouns from the source-of-truth files. Open
resume.md if specific metrics are needed.
- Pick a length variant matched to the surface.
- Draft 2-3 angles, not just one. Different lead credentials, different proof.
- Cut anti-pattern words. Run the cut list above as a final pass.
- Show variants to the subject. Let them pick or remix; never assume the first one wins.
Default Deliverable
When asked to write a bio, return:
- The requested-length variant (3 alternatives, different leading credential)
- A micro version (8 words, X-bio-friendly) as a bonus
- A note on which source facts each draft is grounded in
Format:
### Variant A: [angle, e.g., "founding engineer angle"]
[draft]
Grounded in: career-profile.md "Differentiators #1", resume.md "$COMPANY bullet 1"
### Variant B: [angle]
...
### Micro
[8-word X bio]
Maintenance
When the subject ships a notable new project, lands a new role, or publishes
new work: update the proof inventory. The skill is only as sharp as the
proof inventory.

Use whenever the agent needs to describe a real person to a reader (recruiter "Why this candidate" blurbs, LinkedIn headlines + About sections, conference bios, intro requests, cold outreach openers, "tell me about yourself" answers, X/site bios, panel descriptions, app submission profiles, founder intros). Triggers on "write a bio", "intro me", "one-liner", "pitch me", "About section", "candidate blurb", "outreach opener", "describe me", or whenever copy is being authored that represents a person in their own voice.4---56# Voice78Third-person positioning voice.
