Executive Overview
Over one long weekend I turned loose ideas into four production-ready AI workflows that:

Cut 20+ hours/week of research, inbox triage, and data collection.

Spawned two paid micro-products (credit-research reports & Whop data packs).

Serve as flagship demos that attract consulting clients and affiliate revenue.

Below is a professional, soup-to-nuts breakdown—architecture, security, deployment, AND an internet-first go-to-market plan to ensure these automations don’t just run… they sell.

Technical Architecture at a Glance
Layer Service Purpose
Agent Builder Langflow (self-host) Drag-and-drop LLM pipelines.
Orchestration / Triggers n8n (Docker, ARM64) Cron, webhooks, error handling.
Vector Store ConsumerAI (http://consumerai.info) Hosted Astra-powered embeddings.
External APIs OpenAI, Tavily, Gmail, Whop, YFinance Domain-specific data.
Infrastructure 1 × $6 / mo Hetzner VPS + Cloudflare tunnel HTTPS & basic auth gate.

Key Principle: Stateless Langflow containers + stateful vector DB = horizontal scaling in <5 min (just spin more Langflow pods behind Traefik).

Deep-Dive: Each Workflow
3.1 Credit Research Agent
Problem: Clients pay $49/report for credit-market snapshots but research is manual.
Flow:

Prompt Decomposer – LLM creates sub-topics from the query.

Tavily Search Node – 3 concurrent searches → cleaned JSON.

YFinance Node – Pulls FICO & bond-rate data.

Math / Calc Node – APR deltas & risk ratios.

Analyst LLM – Generates 500-word synthesis w/ citations.

n8n converts Markdown → PDF and emails it to user.

Avg runtime: 42 s | Cost: ≈ $0.002/headline

3.2 Gmail Assistant Agent
Problem: 150+ daily emails; SLA <24 h.
Flow: Gmail Loader → LLM classify + summarize → Priority queue → Draft replies via Gmail Draft API.
Add-on: n8n cron job at 06:00 ET pushes top 5 items to Slack.

3.3 Whop Scraper & Data Product
Demo: https://whop.com/futuristicwealth/whop-data-scarper-3O3pcSGuHyZjNM/app/

Step Node Function
1 HTTP Loader GET vendor leaderboard HTML
2 BeautifulSoup Custom Parse seller names, sales, GMV
3 LLM “Trends Analyst” Enrich: growth %, niche tags
4 n8n Sheets Append to Google Sheet (public API)
5 Stripe Checkout Link $29/mo API access for creators

3.4 Retrieval-Augmented Q&A
Docs → ConsumerAI vector DB → Retriever → Answer LLM.
Latency: 1.2 s for <10K docs; scales linearly.
Security: Embeddings strip PII; raw docs stored S3 private bucket.

Deployment, Security & Compliance
Docker-Compose for Langflow + n8n + Traefik.

Cloudflare Auth (TOTP) on /langflow and /n8n.

Environment vault (Doppler) injects all API keys at runtime.

GDPR: Data-subject deletes propagate to ConsumerAI via webhook.

Logging & APM: Loki + Grafana; 7-day retention, no PII.

Monetization Stack
Revenue Stream CAC Pricing Stack
Credit Reports (PDF) $11 (Reddit Ads) $49 one-off Gumroad + n8n webhook
Whop Data API Organic (Whop directory) $29/mo Stripe billing portal
Affiliate Toolkit $0 (content) 10-40 % Links below
Full Funnel: Getting Users & Clients Online
6.1 Top-of-Funnel Visibility
Channel Weekly Cadence Content
YouTube Shorts 3× 30-sec loom showing Langflow canvas → CTA “link below”
LinkedIn 2× Case-study carousels w/ KPI screenshots
Reddit (r/NoCode, r/LowCode) 3 comments/day Non-spammy teardown of someone’s automation problem, link to demo
Indie Hackers & Hacker News “Show HN” 1 post/2 weeks Publish open-source Langflow template (.json) + README

6.2 Middle-of-Funnel
Lead Magnet: Free “7-Prompt AI Research Kit” (n8n sends on email capture).

Email Sequence (Beehiiv):

Day 0 – Welcome & tool stack infographic

Day 2 – Behind-the-scenes video build

Day 5 – 50 % off first credit report

Day 10 – Invite to Live Q&A (Twitch)

6.3 Bottom-of-Funnel
Calendly + Paid Discovery Call ($97): Integrated into n8n when lead score ≥ 60.

Proposal Engine (GPT-4o via Langflow): Auto-generates SOW & timeline in Google Docs.

Client Portal: Self-serve dashboard built on Retool => live scraping stats + report history.

Key Metrics to Track
KPI Target Tool
Lead → Email Opt-In > 30 % Beehiiv analytics
Email → Purchase > 8 % Stripe conversion
Automation Cost / Revenue < 5 % n8n + Grafana
Average Report Turnaround < 60 s Loki logs
MRR Churn (Whop API) < 5 % / mo ChartMogul
Roadmap
Voice Interface: ElevenLabs + Twilio → voice mail triage.

One-click Whitelabel: Terraform script to deploy entire stack per client.

SOC 2 Lite controls for enterprise prospects.
