GuestPulse — Podcast Hosts Spend 3 Hours Researching Every Guest. This Does It in 90 Seconds Flat.
Independent podcast hosts manually stalk every guest across LinkedIn, Twitter, their newsletter, and old podcast appearances before every recording. GuestPulse takes a guest's name and website, scrapes their public footprint, and delivers a structured 1-page brief with talking points, audience crossover signals, and three controversy-safe conversation angles. Research is done before your coffee cools.

What is it?
Podcast hosts on r/podcasting and the Podcast Movement community consistently report that guest research is the most time-consuming pre-production task — 2 to 4 hours per guest for shows that publish weekly. Existing tools like PodMatch and Rephonic focus on guest matching not pre-interview research. GuestPulse accepts a guest URL or LinkedIn handle, uses Firecrawl to extract public content from their site, recent social posts, and past podcast appearances via Listen Notes API, then passes everything to Claude to generate a structured brief: five talking points ranked by audience fit, three non-obvious questions the guest has never been asked, and one hook sentence for episode marketing. The brief is downloadable as a PDF or shareable link. This is a clean two-weekend build with Firecrawl, Listen Notes API, Claude, and Next.js — no scraping bans, all legitimate APIs, ships fast.
Why now?
Firecrawl's stable v1 API launched in early 2026 makes public web extraction reliable enough to build a production product on without scraping brittle HTML directly — this pipeline was not safely buildable 18 months ago.
- ▸Enter a guest URL or LinkedIn handle, get a structured 1-page brief in under 90 seconds
- ▸Listen Notes integration surfaces all past podcast appearances so you know what topics are over-covered
- ▸Three non-obvious questions generated by Claude based on topics the guest has rarely discussed publicly
- ▸Downloadable PDF brief with your show logo on the $49 tier
Target Audience
Independent podcast hosts publishing at least twice per month — estimated 400k active English-language podcasts with at least one guest episode per month
Example Use Case
A host with a twice-weekly business podcast enters a guest's LinkedIn URL 20 minutes before a pre-call, gets a structured brief with five audience-matched talking points and three questions the guest has never been asked on other shows, and records the best episode of the season.
User Stories
- ▸As a podcast host, I want to paste a guest URL and receive a structured research brief in under 2 minutes, so that I can prepare for an interview without spending 3 hours on manual research.
- ▸As a host, I want to see every podcast the guest has appeared on with their discussed topics, so that I can ask questions they have never been asked on other shows.
- ▸As a show producer, I want to download a branded PDF brief, so that I can share guest research with co-hosts and editors without reformatting it myself.
Done When
- ✓Brief generation: done when pasting a guest website URL produces a complete brief with talking points, questions, and hook sentence visible on screen within 2 minutes.
- ✓Past appearances: done when the brief includes at least one section listing podcast shows the guest has appeared on, sourced from Listen Notes data.
- ✓PDF export: done when clicking Download PDF produces a formatted file that opens correctly in a PDF viewer with all brief sections present.
- ✓Billing: done when a free user who has used 3 credits sees an upgrade prompt, completes Stripe checkout at $19/month, and immediately generates a new brief.
Is it worth building?
$19/month x 150 hosts = $2,850 MRR at month 3. $49/month x 50 high-frequency shows = $2,450 MRR. Math assumes 5% conversion of 5k monthly visitors driven by podcast community SEO and ProductHunt.
Unit Economics
CAC: $15 via podcast community organic posts. LTV: $342 (18 months at $19/month). Payback: 1 month. Gross margin: 82%.
Business Model
Freemium with per-brief credits
Monetization Path
Free: 3 briefs/month. $19/month: 20 briefs. $49/month: unlimited briefs, team seats, white-label PDF with your show logo.
Revenue Timeline
First dollar: week 2 via r/podcasting beta offer. $1k MRR: month 2. $5k MRR: month 7.
Estimated Monthly Cost
Firecrawl API: $20, Listen Notes API: $15, Claude API: $30, Supabase: $25, Vercel: $20. Total: ~$110/month at launch.
Profit Potential
Side-income viable at $2k–$5k MRR. Not a unicorn but a clean lifestyle business with low churn.
Scalability
High — add CRM for guest pipeline management, past episode tracking, sponsor talking point suggestions, and agency white-label.
Success Metrics
Week 2: 200 free briefs generated. Month 2: 80 paid hosts. Month 3: 75% of paid users generate at least 4 briefs/month.
Launch & Validation Plan
Post in r/podcasting offering to generate free briefs for any host who replies with their next guest URL — collect 50 briefs, measure how many ask how to get more.
Customer Acquisition Strategy
First customer: post in Podcast Movement Facebook Group and r/podcasting offering to generate the first 3 guest briefs free and personally deliver them via DM — convert the ones who ask for more into $19/month. Ongoing: SEO on 'podcast guest research tool', ProductHunt launch, partnerships with podcast editing services.
What's the competition?
Competition Level
Low
Similar Products
PodMatch (guest matching not research), Rephonic (show analytics not guest briefs), ChatGPT manual prompting (no Listen Notes data, no PDF, no structure) — none combine past appearance data with structured brief generation.
Competitive Advantage
Listen Notes integration means the brief shows what the guest has already said on 50 other shows — a differentiation no generic research tool offers. Cheaper and faster than hiring a show researcher at $15/hour.
Regulatory Risks
Public web scraping via Firecrawl is ToS-compliant when targeting public pages. Brief content is factual summary of public information — low defamation risk. GDPR: brief data tied to public figures, minimal personal data. Low regulatory risk.
What's the roadmap?
Feature Roadmap
V1 (launch): URL input, 90-second brief generation, PDF export, Stripe billing, Listen Notes past appearances. V2 (month 2-3): guest pipeline CRM, show logo branding on PDF, team seats. V3 (month 4+): episode SEO hook suggestions, sponsor talking point layer, agency white-label.
Milestone Plan
Phase 1 (Week 1): Firecrawl and Listen Notes pipeline, Claude brief generation, Supabase storage. Phase 2 (Week 2): UI, PDF export, Stripe billing, 10 beta hosts. Phase 3 (Month 2): ProductHunt launch, 60 paid hosts.

Architecture Pattern
User submits guest URL -> Firecrawl extracts public content -> Listen Notes API returns past appearances -> Claude generates structured brief JSON -> stored in Supabase -> React PDF renders downloadable output.
Data Model
User has many Briefs. Brief has guest_url, guest_name, talking_points array, questions array, past_appearances array, hook_sentence, and created_at.
Integration Points
Firecrawl API for public web content extraction, Listen Notes API for podcast appearance history, Claude API for brief generation, Supabase for brief storage and auth, Stripe for billing, React PDF for export, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: guest CRM pipeline, episode scheduling, sponsor talking point generation, team collaboration, Calendly integration.
Success Definition
A podcast host who found GuestPulse via Google uses it for every guest for two consecutive months and upgrades to $19/month without any founder contact.
Challenges
The hardest non-technical problem is convincing hosts that AI-generated questions are better than their own gut instinct — positioning matters more than features here, and the product must prove value on the first free brief or it dies.
Avoid These Pitfalls
Do not launch without at least 20 real briefs tested against actual hosts — if the questions sound generic the product dies on first use and you will not get a second chance in tight podcast communities. Do not rely on LinkedIn scraping as a primary source — LinkedIn blocks automated access aggressively and breaks the pipeline. Finding your first 10 paying customers will take longer than building — budget 3x more time for podcast community engagement than development.
Security Requirements
Supabase Auth with Google OAuth, RLS on briefs scoped by user_id, rate limit 10 generate calls/hour per user, input URL validation to prevent SSRF, GDPR: brief content is public data summary with no sensitive personal data stored.
Infrastructure Plan
Vercel for Next.js and API routes, Supabase for Postgres and auth, no file storage (PDFs generated client-side with React PDF), GitHub Actions for CI, Sentry for errors, ~$110/month.
Performance Targets
200 DAU at launch, 500 briefs/day, generation pipeline under 20 seconds end-to-end, dashboard brief list loads under 500ms with Supabase indexed query on user_id.

First Run Experience
On first run: a demo brief for a well-known business podcast guest is pre-loaded showing all sections including talking points, questions, past appearances, and hook sentence. User can immediately read the demo brief and download the PDF. No manual config required: demo brief loads without login or API key entry.
How to build it, step by step
1. Define Supabase schema: users(id, email, plan, credits), briefs(id, user_id, guest_url, guest_name, content_json, created_at). 2. Write lib/research.ts that calls Firecrawl on the guest URL and Listen Notes search API with guest name to return text content and appearance list. 3. Write lib/generate.ts that sends research text to Claude with a structured prompt returning talking_points, questions, past_topics, and hook_sentence as JSON. 4. Build /api/generate POST route that orchestrates research and generation, stores result in Supabase, and returns brief id. 5. Build app/brief/[id]/page.tsx that fetches and renders the brief with BriefCard component. 6. Create PDFExport.tsx using React PDF that renders the brief as a formatted PDF with show logo slot. 7. Add Supabase Auth with Google OAuth and credit decrement on each brief generation. 8. Add Stripe billing for $19 and $49 tiers with credit top-up on subscription. 9. Add a loading state on the generate page with a step-by-step progress indicator (Researching, Analyzing, Writing). 10. Deploy to Vercel and walk full journey: paste a real guest URL, wait 90 seconds, read brief, download PDF, confirm all sections populated correctly.
