AI automation agency owners are actively hiring freelance sales closers and paying per meeting hour because they lack structured onboarding materials to hand off to closers.
What is it?
AI automation agencies are scaling fast in May 2026 but their sales process is still a Google Doc and a prayer. Every new closer they hire needs to understand complex technical offers, handle objections around AI hype, and qualify leads who barely know what a workflow is. CloserKit takes your agency offer, target ICP, and price point, then generates a full closer kit: call script, objection handler, qualification checklist, discovery question bank, and a one-pager the closer can read before the first call. The founder pastes in their offer, answers 5 questions, and downloads a ZIP of ready-to-use docs in under 2 minutes. Built 100% with Next.js, Claude API, and Stripe — no moving parts, no custom backend, ships in a weekend.
Why now?
The May 2026 AI agency boom has created a massive wave of non-technical founders hiring their first closers with zero enablement materials — Upwork is flooded with closer job posts right now.
- ▸Offer-to-kit generator: Claude produces call script, objection handler, and qualification checklist from a 5-question form.
- ▸Instant ZIP download: all docs packaged as DOCX and PDF, ready to email to any closer.
- ▸Objection bank builder: generates 15 AI-specific objections with scripted responses tailored to your price point.
- ▸Regeneration with version history: tweak one answer, regenerate only the changed section.
Target Audience
AI automation agency owners running 1-5 person teams, ~50k active on Reddit and X right now, hiring closers every 60-90 days.
Example Use Case
Marcus runs a 3-person AI automation agency and just hired his first closer. He pastes his offer into CloserKit, gets a 12-page closer pack in 90 seconds, and his closer books a paid call on day one without a single training session.
User Stories
- ▸As an AI agency owner, I want to generate a full closer onboarding kit from my offer description, so that my new closer can run calls on day one without training sessions.
- ▸As a sales closer, I want a pre-built objection handler for AI automation offers, so that I can respond confidently when prospects ask technical questions.
- ▸As an agency coach, I want to white-label closer kits for my students, so that I can add a tangible deliverable to my program without manual work.
Done When
- ✓Kit generation: done when submitting the 5-question form returns a ZIP containing all 6 sections within 30 seconds.
- ✓Payment gate: done when unpaid users see only a blurred preview and are redirected to Stripe before downloading.
- ✓Download: done when clicking the success page button immediately triggers a ZIP file download with correctly named files.
- ✓Objection bank: done when the downloaded objection handler contains at least 12 AI-specific objections with scripted responses matching the entered price point.
Is it worth building?
$29/month x 60 subscribers = $1,740 MRR at month 3. $9 per-kit x 100 one-time buyers adds $900/month in parallel. Realistic $2,500 MRR by month 4.
Unit Economics
CAC: $5 via Reddit DMs (time only). LTV: $87 (3 months at $29/month). Payback: immediate on per-kit plan. Gross margin: 85%.
Business Model
Pay-per-generation ($9 per kit) or unlimited subscription at $29/month.
Monetization Path
Free preview of 1 section unlocks after email capture. Full kit download requires payment. Subscription unlocks unlimited regenerations and version history.
Revenue Timeline
First dollar: day 4 via beta DM offer. $1k MRR: month 3. $5k MRR: month 10 with add-ons.

Profit Potential
Side income at $1k-$3k MRR. Full-time only with add-on products.
Scalability
Medium — can expand to closer performance tracking, CRM template exports, and white-label kits for agency coaches.
Success Metrics
Week 1: 50 landing page signups. Week 2: 10 paid kits generated. Month 2: 30 active subscribers at $29/month.
Launch & Validation Plan
Post in r/agency and r/AIAutomation offering 5 free kits in exchange for feedback DMs. Validate before building.
Customer Acquisition Strategy

What's the competition?
Competition Level
Low
Similar Products
Copy.ai for sales copy (not structured closer kits), Gong Engage (enterprise, $10k+), ChatGPT custom prompts (no structure, no download, no ICP tuning).
Competitive Advantage
Purpose-built for AI automation offer complexity — generic sales tools produce generic scripts that confuse closers when prospects ask what an n8n workflow actually is.
Regulatory Risks
Low regulatory risk. GDPR: do not store offer content longer than 30 days without consent.
What's the roadmap?
Feature Roadmap
V1 (launch): form, Claude generation, ZIP download, Stripe pay-per-kit. V2 (month 2-3): subscription plan, regeneration, version history. V3 (month 4+): white-label export, CRM template sync.
Milestone Plan
Phase 1 (Week 1-2): form + Claude API + ZIP download working end-to-end. Phase 2 (Week 3-4): Stripe gate + Supabase logging + deployed to Vercel. Phase 3 (Month 2): 10 paying customers + subscription plan live.
How do you build it?
Tech Stack
Next.js, Claude API, Stripe, Supabase, Resend — build with Cursor for API routes, v0 for form UI, Lovable for dashboard.
Suggested Frameworks
Next.js App Router, Vercel AI SDK, Stripe Checkout
Time to Ship
5 days
Required Skills
Claude API prompt engineering, Stripe Checkout, Next.js file download via API route.
Resources
Anthropic docs, Stripe Checkout docs, Next.js App Router docs, JSZip for ZIP generation.
MVP Scope
app/page.tsx (landing + offer form), app/api/generate/route.ts (Claude prompt + JSZip response), app/api/checkout/route.ts (Stripe payment link), app/download/page.tsx (post-payment download), lib/prompts.ts (Claude prompt templates), lib/stripe.ts (Stripe client), components/OfferForm.tsx (5-question form UI), .env.example (required env vars).
Core User Journey
Paste offer -> answer 5 questions -> pay $9 -> download ZIP -> hand to closer.
Architecture Pattern
Form submit -> Claude API with structured prompt -> JSZip assembles DOCX files -> Stripe payment link gate -> ZIP streamed to browser on success.
Data Model
User has many Kits. Kit has one OfferInput (5 fields), one GeneratedContent (JSON of sections), one DownloadEvent.
Integration Points
Claude API for kit generation, Stripe for payments, Resend for receipt email, Supabase for generation history, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: CRM integration, closer performance tracking, team accounts, white-label, mobile app.
Success Definition
A stranger finds CloserKit via Reddit, pays without contacting the founder, downloads the kit, and hands it to a closer who books a call the same week.
Challenges
Distribution is the hard problem — agency owners are drowning in tools and this needs to reach them at the exact moment they post a closer job. Timing the outreach to Upwork job postings is the real unlock.
Avoid These Pitfalls
Do not spend time on a dashboard before validating that people actually pay for the kit. Do not let Claude output unstructured text — enforce section-by-section JSON output or the ZIP assembly breaks. Finding the first 10 paying customers will take longer than building — budget 3x more time on Reddit DMs than coding.
Security Requirements
Supabase Auth with magic link. RLS on all kit rows. Stripe webhook signature verification required. Input sanitized before Claude prompt injection.
Infrastructure Plan
Vercel for Next.js hosting, Supabase for Postgres + auth, no file storage needed (ZIP generated on demand), Sentry for error tracking.
Performance Targets
100 DAU at launch, 500 req/day. Claude generation under 15s. Page load under 2s. No caching needed at this scale.

First Run Experience
On first run: a pre-filled example offer is loaded in the form for an AI chatbot agency at $3,000/month retainer. User can immediately click Generate to see a blurred preview of all 6 kit sections. No manual config required: Claude API key is server-side, Stripe is in test mode with a demo $9 payment.
How to build it, step by step
1. Define Claude prompt schema: 5 input fields mapped to 6 output sections as JSON. 2. Run npx create-next-app closerkit --typescript. 3. Build OfferForm.tsx with react-hook-form for the 5-question input. 4. Build app/api/generate/route.ts calling Claude with structured JSON output mode. 5. Add JSZip to assemble DOCX-formatted text files into a downloadable ZIP. 6. Set up Stripe Checkout session in app/api/checkout/route.ts with a $9 price. 7. Build post-payment success page that triggers the ZIP download via a signed URL. 8. Add Supabase table to log generation events for version history. 9. Deploy to Vercel and set all env vars. 10. Verify: submit the form, complete Stripe checkout, confirm ZIP downloads with all 6 sections populated.
