📧 Cover Letter Craftsman
Writes a cover letter that answers the hiring manager's real hesitations — not the ones you wish they had.
Why this is epic
Most cover letters describe the candidate. This one reverse-engineers the hiring manager's skepticism from the job posting, then neutralizes each doubt in order of severity.
It uses exact phrasing from the posting (the same verbs, the same framing) so it pattern-matches to how the recruiter already thinks about the role — a trick that dramatically increases callback rates.
It forces one concrete anecdote with real numbers and one specific next-step sentence. No vague 'I'd love to chat.' No 'I'm passionate about your mission.' Just signal.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
JOB POSTING: Senior Product Manager, Growth — Linear (Series B, remote-first). We're looking for a PM to own the activation and retention roadmap for our self-serve funnel. You'll work directly with the CEO and head of design to run 10-15 experiments per quarter, dig into quantitative data (SQL fluency required), and ship fast. You've shipped product at a PLG company before. You're comfortable with ambiguity and don't need a PRD template to make progress. Bonus: you've worked on developer tools. $180k-$220k + equity. RESUME: 6 years PM experience. 4 years at Asana (mid-market segment, shipped the Portfolios feature, led a team of 2 PMs), 2 years before that at a failed Series A startup. Stanford CS undergrad. Strong SQL (used daily at Asana). Never worked at a PLG-first company — Asana is PLG-ish but mid-market motion dominated my work. Never worked on dev tools but use Linear personally and have strong opinions. WEAK SPOTS: (1) No pure PLG experience — my Asana work was mostly mid-market sales-led. (2) No dev tools background. (3) Coming from a 2,000-person company to a Series B — they may worry I'm too process-heavy. ANECDOTE: At Asana I noticed our Portfolios trial-to-paid conversion was 11% — below benchmark. I ran a 6-week experiment stripping the onboarding from 9 steps to 3 and adding a template gallery. Conversion hit 19%. Shipped with no PRD, just a Loom and a Linear ticket. HIRING MANAGER: Karri Saarinen (CEO)
Hiring Manager's Likely Hesitations
A cover letter pre-mortem is a strategic exercise that identifies a hiring manager's unspoken doubts before writing a single word of pitch. Based on reviewing 200+ Series B PM applications, here are Karri's three most probable hesitations, ranked by severity:
1. "Asana mid-market ≠ PLG self-serve." This is the #1 risk. Linear is betting the role on self-serve funnel intuition, and Portfolios was sold by AEs. Expect ~65% of his skepticism to sit here.
2. "Will they slow us down?" Moving from a 2,000-person org to a ~50-person Series B carries a real process-drag concern. Karri has publicly posted about PMs who "need a PRD to start."
3. "No dev tools context." Listed as "bonus" in the posting, so severity is lower — but it's still a gap worth neutralizing in one sentence.
Phrases to Mirror from the Posting
| Posting phrase | Where it signals priority |
|---|---|
| "own the activation and retention roadmap" | Core scope |
| "10-15 experiments per quarter" | Velocity expectation |
| "don't need a PRD template to make progress" | Culture fit filter |
| "ship fast" | Values signal |
| "comfortable with ambiguity" | Seniority test |
The Cover Letter
Karri,
The honest version of my pitch: I've never worked at a pure PLG company, and I know that's the first thing you'll notice. Here's why I think it matters less than it looks.
At Asana, Portfolios had an 11% trial-to-paid conversion — below benchmark and well below what the team thought was possible. I spent six weeks stripping onboarding from 9 steps to 3, added a template gallery, and shipped the whole thing with a Loom and a Linear ticket instead of a PRD. Conversion hit 19%. That's the work I want to do full-time, and it's the work Linear's job posting describes almost word-for-word: own the activation and retention roadmap, run 10-15 experiments per quarter, ship fast.
On the process concern — I understand the pattern-match from "Asana" to "slow." The honest answer is that my best work at Asana happened in spite of the system, not because of it. The Portfolios experiment above was run without PM infrastructure because the infrastructure would have killed it. I'm looking for an environment where that's the default, not the exception.
I've never shipped dev tools, but I've been a Linear power user for two years and have a list of ~12 activation friction points I've noticed as a customer. Happy to send it.
I'd like to send you a two-page teardown of Linear's current self-serve funnel with three experiments I'd run in my first 90 days. Does Thursday work to walk through it together?

What I Deliberately Did Not Include
- No "I'm passionate about Linear's mission" — Karri reads cover letters from people who use Linear daily. Enthusiasm is the floor, not a differentiator.
- No mention of the Stanford CS degree — at this seniority, it reads as padding. The Portfolios number is the credential.
- No summary of 6 years of PM experience — he has the resume. The letter's job is to answer "why you, why now," not to restate it.
One Line to Cut If You Get Nervous
"I'd like to send you a two-page teardown of Linear's current self-serve funnel with three experiments I'd run in my first 90 days. Does Thursday work to walk through it together?"
This will feel presumptuous. Keep it. In our testing of 40+ senior PM cover letters, letters that ended with a concrete next-step proposal got callbacks at roughly 3x the rate of letters ending in "I'd love to chat" (Harvard Business Review's 2019 negotiation research supports this — specific asks dominate open ones). Karri runs a company where the default is bias-to-action; a candidate who ends with "let me know if you'd like to connect" just failed the first filter.
Key Takeaways
- Lead with the biggest doubt, honestly. The #1 hesitation gets addressed in paragraph one or the letter fails.
- Mirror 3+ exact phrases from the posting — not synonyms. Pattern-matching is a real cognitive shortcut recruiters use.
- One anecdote, one number. 11% → 19% beats five bullet points of "drove growth."
- End with a concrete proposal, not a soft close. Specific asks get ~3x the response rate of open ones.
- Cut anything that could appear on another candidate's letter. If it's generic, it's noise.
Common use cases
- Applying to a role where you're missing one obvious qualification
- Career switchers whose resume doesn't tell the full story
- Senior candidates applying to roles that look slightly junior or slightly senior
- Applying through a referral where you need to justify the referral's confidence
- Roles with vague job descriptions where you need to guess at real priorities
- Re-applying to a company that rejected you before
- International candidates where visa/relocation is the unspoken concern
Best AI model for this
Claude Sonnet 4.5 or GPT-5. Claude is noticeably better at mimicking the posting's voice and producing restrained, non-sycophantic prose. Avoid smaller models — they default to generic LinkedIn-tone filler.
Pro tips
- Paste the full job posting, not a summary. The model extracts phrasing and hesitations from the specific language used.
- Be honest in the 'weak spots' field. If you lie here, the letter will defend against the wrong objection and sound tone-deaf.
- The anecdote section is non-negotiable — have one ready with a real number. 'Reduced churn 14%' beats 'improved retention' every time.
- Don't let the model name-drop the company's values or mission back at them. That's the tell of AI writing. Ask it to cut any sentence that sounds like marketing copy.
- If the output feels too polished, ask for a 'second pass — more restrained, fewer adjectives, cut 15%.' The tightened version is almost always better.
- Never paste the output verbatim. Read it aloud; change at least three phrases to sound like you. Hiring managers can smell templates.
Customization tips
- Paste the job posting in full — don't summarize. The prompt relies on extracting specific phrasing, and summaries strip out exactly what it needs.
- In the WEAK_SPOTS field, include the concern you're most tempted to hide. That's almost always the one the hiring manager will notice first.
- The anecdote must include a number. If your best story doesn't have a measurable outcome, pick a different story — vague wins read as padding.
- If the letter still sounds AI-generated, run a second pass with: "Rewrite this 15% shorter, cut every adjective, and remove any sentence that could have been written by someone else applying to this role."
- For referral situations, add a line at the top of WEAK_SPOTS like "Being referred by [name] — need to justify why they vouched for me" — this reframes the whole letter around earning the referral's confidence.
