RedditLense - Automated Reddit Prospect Radar with CRM Sync
Your SDRs are spending three hours per day manually scrolling Reddit looking for buying signals like 'anyone recommend a tool for X' — that is a $90/hour problem dressed up as a $15/hour task. RedditLense monitors keyword-triggered Reddit posts in real-time, scores each post for buyer intent using NLP, and pushes warm leads directly into HubSpot or a Pipedrive webhook. First five SDRs pay $99/month each before you write a single line of marketing copy.

— seeded from real developer complaints
Sales reps at software companies report spending several hours per day manually browsing Reddit to find posts where potential customers are expressing buying intent or asking for tool recommendations, with no systematic way to capture or prioritize these opportunities or sync them to a CRM.
What is it?
Sales teams selling to SMBs and startups have discovered that Reddit is a goldmine of organic buying intent — posts like 'we outgrew Notion, what do teams your size use' or 'looking for a cheaper Salesforce alternative' are literal sales opportunities. The problem is that no one has time to monitor 40 subreddits simultaneously, and manual workflows fall apart the moment the SDR takes a vacation. RedditLense uses Reddit's official pushshift-compatible API to stream new posts and comments matching configurable keyword sets, runs each match through a lightweight intent-scoring prompt on Claude Haiku (cheap), filters out noise, and pushes qualified leads as CRM contacts with full context — subreddit, post link, estimated company size if mentioned, and suggested opener — via Zapier webhook or native HubSpot integration. The SDR dashboard shows a live feed of scored opportunities ranked by urgency. Why 100% buildable right now: Reddit's official Data API is stable, Claude Haiku costs under $0.01 per 1,000 tokens making intent scoring economically viable at scale, and HubSpot's free CRM tier accepts webhook contacts — this exact stack was proven by similar tools in the Twitter monitoring space.
Why now?
Reddit's official Data API became stable and affordable in late 2024 after the third-party app controversy forced Reddit to productize their API properly, and Claude Haiku dropping to sub-cent token costs in 2025 makes per-post intent scoring economically trivial — this combination makes real-time Reddit prospecting viable for the first time.
- ▸Real-time Reddit keyword monitoring across up to 50 configurable subreddits with streaming post ingestion via Reddit Data API.
- ▸Claude Haiku intent scoring that classifies each post as hot, warm, or cold lead with a one-line suggested outreach opener.
- ▸One-click CRM push that creates a HubSpot contact or fires a Zapier webhook with post URL, subreddit, keyword match, and intent score.
- ▸SDR dashboard with a live ranked lead feed, keyword performance stats, and daily digest email of top 10 opportunities.
Target Audience
SDRs and sales-led SaaS founders at companies with 5–50 person sales teams, roughly 80,000 such roles in North America actively prospecting SMBs.
Example Use Case
A five-person SDR team at a project management SaaS sets up 12 keywords across r/startups, r/entrepreneur, and r/smallbusiness, gets 8 qualified leads on day one with suggested openers, closes one deal in week two, and the manager cancels their manual prospecting ritual forever.
User Stories
- ▸As an SDR at a SaaS company, I want to receive ranked Reddit leads matching my product category daily, so that I can reach out to warm prospects before competitors do.
- ▸As a sales manager, I want to see which keyword sets generate the most qualified leads each week, so that I can optimize our Reddit prospecting strategy. As an SDR, I want to push a Reddit lead to HubSpot with one click including the full post context, so that I never have to manually copy-paste prospect information again.
Acceptance Criteria
Keyword Monitoring: done when a test post containing a configured keyword appears in the lead feed within 5 minutes of posting. Intent Scoring: done when Claude Haiku correctly classifies 8 out of 10 test posts as hot, warm, or cold with a non-empty suggested opener. HubSpot Push: done when clicking push creates a new HubSpot contact with post URL and intent score in the notes field. Stripe Billing: done when trial expiry blocks keyword config saving and upgrade restores access immediately.
Is it worth building?
$99/month × 30 SDR seats = $2,970 MRR at month 2. $99/month × 150 seats = $14,850 MRR at month 6. Math assumes 5% conversion from cold email to SDR managers and sales ops leads found on LinkedIn.
Unit Economics
CAC: $30 via LinkedIn cold email at 5% conversion on 20 outreach messages per customer. LTV: $1,188 (12 months at $99/month). Payback: under 1 month. Gross margin: 88%.
Business Model
Per-seat SaaS subscription
Monetization Path
Free 7-day trial with 50 monitored keywords converts to paid at 20% when lead volume proves value in the first week.
Revenue Timeline
First dollar: week 2 via first paid SDR seat. $1k MRR: month 2 with 10 seats. $5k MRR: month 5 with 50 seats. $10k MRR: month 9 with 100 seats.
Estimated Monthly Cost
Reddit Data API: $0 (free tier sufficient at launch), Claude Haiku: $15 for 1.5M tokens at typical volume, Vercel: $20, Supabase: $25, Stripe fees on $3k MRR: ~$105. Total: ~$165/month at launch.
Profit Potential
Full-time viable at $5k–$15k MRR with 50–150 seats.
Scalability
High — expand to LinkedIn posts, Twitter/X, and G2 review monitoring. Add team plans with shared keyword libraries.
Success Metrics
Week 1: 20 SDR signups on free trial. Week 2: 5 paid conversions. Month 2: 30 paying seats, 75% month-2 retention.
Launch & Validation Plan
Post in r/sales and r/learnprogramming asking how SDRs currently monitor Reddit, DM 15 sales ops leads on LinkedIn offering a free two-week trial for one keyword set, measure if they use the lead feed daily.
Customer Acquisition Strategy
First customer: find 20 SDR managers at Series-A SaaS companies on LinkedIn Sales Navigator, send a cold email with a screenshot of three actual Reddit posts that match their product category and ask if they would pay $99/month to get these automatically. Broader channels: r/sales, r/entrepreneur, Sales Hacker community Slack, LinkedIn content on social selling, and a free Reddit prospecting playbook as SEO bait.
What's the competition?
Competition Level
Medium
Similar Products
F5Bot monitors Reddit keywords but has no intent scoring or CRM integration. Mention.com is broad social listening with no sales workflow. Keyworddit is keyword research only — none combine real-time monitoring plus NLP intent scoring plus CRM push.
Competitive Advantage
Intent scoring with suggested openers cuts SDR time-to-reply from hours to seconds — generic Reddit monitoring tools like F5Bot deliver raw posts with zero qualification or CRM integration.
Regulatory Risks
Reddit ToS compliance required — must use official Data API, not scraping. GDPR: Reddit usernames are public but storing them requires a privacy policy. Low regulatory risk overall.
What's the roadmap?
Feature Roadmap
V1 (launch): Reddit streaming, Haiku intent scoring, HubSpot push, lead feed dashboard. V2 (month 2-3): team shared keyword libraries, Pipedrive integration, Slack lead alerts. V3 (month 4+): Twitter/X monitoring, lead reply assistant, conversion rate tracking.
Milestone Plan
Phase 1 (Week 1-2): Reddit stream worker, intent scorer, Supabase storage, basic lead feed — done when 10 real leads appear from test keywords. Phase 2 (Week 3-4): HubSpot integration, Stripe billing, keyword config UI live — done when first beta SDR pays. Phase 3 (Month 2): daily digest email, team plan, Slack alerts — done when 5 teams active.

Resources
Reddit Data API docs, Claude Haiku pricing page, HubSpot API docs, Zapier webhook docs.
MVP Scope
Reddit stream worker (workers/reddit_stream.py), intent scoring service (services/intent_scorer.ts), Supabase leads table (supabase/migrations/), Next.js lead feed dashboard (app/dashboard/), keyword config UI (app/settings/keywords/), HubSpot webhook handler (app/api/crm/), daily digest email (jobs/digest.ts), Stripe billing (app/api/stripe/), landing page (app/page.tsx).
Core User Journey
Sign up -> configure 5 keywords and 3 subreddits -> receive first scored lead within 60 minutes -> push to HubSpot with one click -> upgrade to paid before trial ends.
Architecture Pattern
Reddit Data API stream -> Supabase queue -> Claude Haiku intent scorer -> lead record stored in Postgres -> real-time dashboard update via Supabase subscriptions -> HubSpot webhook push on hot leads -> Resend daily digest email.
Data Model
User has many KeywordSets. KeywordSet has many Leads. Lead has one IntentScore, one SubredditSource, and one CRMPushEvent. User has one BillingSubscription.
Integration Points
Reddit Data API for post streaming, Claude Haiku for intent scoring, Supabase for lead storage and real-time updates, HubSpot API for CRM contact creation, Zapier webhook for custom CRM integrations, Stripe for billing, Resend for daily digest emails.
V1 Scope Boundaries
V1 excludes: LinkedIn monitoring, Twitter monitoring, team shared keyword libraries, Salesforce integration, mobile app, white-label.
Success Definition
An SDR at a company the founder has never spoken to signs up, configures their own keywords, gets a qualified lead on day one, pushes it to HubSpot, and renews after month one.
Challenges
The hardest non-technical problem is convincing sales managers that Reddit leads convert — you need to show closed deals in the first 30 days or churn will spike at month two. Distribution requires reaching sales ops and SDR managers directly, not developers, which means LinkedIn outreach and sales community Slack groups rather than ProductHunt.
Avoid These Pitfalls
Do not build Salesforce integration before HubSpot is proven — start with the most common free CRM first. Do not flood SDRs with cold leads — a single false positive on day one destroys trust faster than 10 true positives rebuild it. Finding your first 10 paying SDR seats will take longer than building the product — budget 3x more time for LinkedIn outreach than development.
Security Requirements
Auth: Supabase Auth with Google OAuth. RLS on leads and keyword_sets tables scoped to user_id. Rate limiting: 60 req/min per user via Vercel middleware. Input validation on keyword strings to prevent injection. GDPR: Reddit usernames stored as-is (public data) with deletion endpoint at DELETE /api/user/data.
Infrastructure Plan
Hosting: Vercel for Next.js and API routes. Database: Supabase Postgres. Reddit stream worker: Vercel Cron every 5 minutes calling a serverless function. CI/CD: GitHub Actions with Vercel preview deploys. Environments: local, Vercel preview, Vercel prod. Monitoring: Sentry for errors, Vercel Analytics. Infrastructure cost: ~$45/month.
Performance Targets
Expected load at launch: 50 DAU, 500 keyword checks/day. Lead feed API response: under 400ms. Page load: under 2s LCP. Caching: CDN for static assets, Supabase query caching for keyword_sets reads.

How to build it, step by step
1. Scaffold Next.js app with npx create-next-app and set up Supabase project with leads and keyword_sets tables. 2. Build Reddit stream worker in Python using PRAW library to poll configured subreddits every 60 seconds for keyword matches. 3. For each match, call Claude Haiku with a five-line intent scoring prompt returning hot/warm/cold plus a suggested opener. 4. Store lead record in Supabase with all metadata and trigger a Supabase real-time event. 5. Build Next.js lead feed dashboard with Supabase real-time subscription showing live ranked cards. 6. Add keyword configuration UI where users add subreddits and keywords. 7. Build HubSpot webhook push button on each lead card using HubSpot Contacts API. 8. Set up Stripe subscription with Stripe Checkout and webhook updating user.plan in Supabase. 9. Build Resend daily digest job that emails the top 10 leads ranked by intent score. 10. Deploy to Vercel, set Reddit stream worker as a Vercel Cron job every 5 minutes.
