An indie builder made over $12k in 8 months by building a simple affordable lead connection tool that LinkedIn and HubSpot were too expensive or complex to replace.
What is it?
Local service businesses and solo freelancers generate leads from Google, Yelp, and referrals but have zero affordable system to follow up via the channels prospects actually answer — WhatsApp and SMS. LeadPing lets users import a lead list, set a 3-step outreach sequence (day 0, day 2, day 5), and auto-sends via Twilio SMS or WhatsApp Business API. Replies land in a unified inbox, and a simple Kanban board tracks lead stage. The entire product is one pricing tier at $39/month with no per-seat nonsense. This is fully buildable with Twilio's stable WhatsApp API, Supabase for data, and Next.js — the hardest part is getting WhatsApp Business API approval which takes 48 hours via a registered Meta partner.
Why now?
WhatsApp Business API became self-serve via Meta's cloud API in late 2023 and Twilio's WhatsApp tier dropped to near-zero cost — the infrastructure cost barrier that kept this a $500/month enterprise feature is now gone.
- ▸CSV lead import with field mapping (Implementation: Papa Parse on client, store in Supabase leads table)
- ▸3-step SMS and WhatsApp sequence builder with day-delay scheduling
- ▸Unified reply inbox showing all inbound SMS and WhatsApp in one feed
- ▸Simple Kanban board with stages: New, Contacted, Replied, Closed
Target Audience
Independent service businesses (plumbers, coaches, agencies, recruiters) — 5M+ in the US alone, most paying nothing or using manual WhatsApp.
Example Use Case
Carlos runs a roofing company and gets 40 web leads a month. He imports the CSV into LeadPing, sets a 3-message SMS sequence, and converts 8 more leads per month who previously ghosted his voicemails — adding $6,400/month in revenue.
User Stories
- ▸As a roofing contractor, I want to auto-send a 3-message SMS sequence to every new web lead, so that I stop losing jobs to competitors who respond faster.
- ▸As a freelance recruiter, I want to see all WhatsApp replies from candidates in one inbox instead of my personal phone, so that I can manage 50 active leads without missing a response.
- ▸As a local fitness coach, I want to import my monthly inquiry CSV and have follow-ups sent automatically, so that I convert more trial signups without spending 2 hours a day on manual messages.
Done When
- ✓CSV import: done when user uploads a 10-row CSV, maps Name and Phone fields, and sees leads appear in the Kanban New column within 5 seconds.
- ✓Sequence send: done when user activates a sequence and Twilio delivers message 1 to a real phone number within 60 seconds.
- ✓Inbound inbox: done when a reply SMS arrives and appears in the unified inbox feed with the lead name and timestamp without page refresh.
- ✓Stripe billing: done when user enters card details, trial starts, and a confirmation email from Resend arrives within 2 minutes.
Is it worth building?
$39/month x 100 customers = $3,900 MRR at month 3. $39/month x 400 customers = $15,600 MRR at month 8. Assumes 5% conversion on cold outreach to local service Facebook groups.
Unit Economics
CAC: $15 via Facebook ads at $10/day with 2% conversion. LTV: $390 (10-month avg retention at $39/month). Payback: 1 month. Gross margin: 82%.
Business Model
Flat $39/month SaaS, includes 500 SMS/month. Overage at $0.05/SMS.
Monetization Path
14-day free trial with 50 SMS included. Stripe subscription at trial end. Overage auto-billed monthly.
Revenue Timeline
First dollar: week 3 via trial-to-paid conversion. $1k MRR: month 2. $5k MRR: month 5. $15k MRR: month 10.
Estimated Monthly Cost
Twilio: $30 (500 SMS), Supabase: $25, Vercel: $20, Stripe fees: ~$40 at 100 customers. Total: ~$115/month.
Profit Potential
Full-time viable at $5k–$15k MRR.
Scalability
High — add vertical-specific templates, CRM integrations, and team seats.
Success Metrics
20 paying customers by end of month 1. Less than 15% churn at month 2. 60% of users send at least one sequence per week.
Launch & Validation Plan
Post in 3 local business Facebook groups asking if they lose leads because nobody answers calls — collect 20 replies as validation before writing code.
Customer Acquisition Strategy
First customer: DM 30 roofing and HVAC companies via Google Maps with a free 2-week trial offer and a screenshot of a sample sequence — target 5 activations from 30 DMs. Ongoing: Facebook ads targeting local business owners at $10/day, r/smallbusiness posts, cold email to Google My Business leads scraped via Outscraper.
What's the competition?
Competition Level
Medium
Similar Products
HubSpot Sales Hub ($800/month, overkill), Pipedrive ($25/user, email-only), SimpleTexting ($29/month, no CRM) — none combine WhatsApp sequences with a lead Kanban at this price.
Competitive Advantage
10x cheaper than HubSpot, WhatsApp-native (competitors use email), single flat price with no per-seat fees.
Regulatory Risks
TCPA compliance required in US for SMS marketing — users must confirm opt-in consent for each lead. Must display consent disclaimer in sequence builder. GDPR data deletion endpoint required for EU users.
What's the roadmap?
Feature Roadmap
V1 (launch): CSV import, 3-step SMS and WhatsApp sequences, unified inbox, Kanban. V2 (month 2-3): AI message suggestions, sequence templates by vertical. V3 (month 4+): CRM integrations, team seats, voice call logging.
Milestone Plan
Phase 1 (Week 1-2): schema, CSV import, sequence builder, Twilio send ships. Phase 2 (Week 3-4): inbound webhook, inbox UI, Stripe billing ships. Phase 3 (Month 2): 20 paying customers via cold outreach.
How do you build it?
Tech Stack
Next.js, Twilio SMS and WhatsApp API, Supabase, Resend for email alerts, Stripe — build backend in Cursor, UI components with v0, deploy on Vercel.
Suggested Frameworks
Twilio Node SDK, Supabase JS, Stripe SDK
Time to Ship
3 weeks
Required Skills
Twilio API, Next.js, Supabase, basic Stripe billing.
Resources
Twilio WhatsApp quickstart, Supabase auth docs, Stripe subscription docs.
MVP Scope
app/page.tsx (landing), app/dashboard/page.tsx (main Kanban), app/api/send/route.ts (Twilio trigger), app/api/webhook/twilio/route.ts (inbound handler), lib/db/schema.ts (leads, sequences, messages tables), lib/twilio.ts (send helpers), components/KanbanBoard.tsx, components/SequenceBuilder.tsx, seed.ts (demo leads), .env.example.
Core User Journey
Sign up -> import CSV -> build 3-step sequence -> activate -> receive first reply in inbox -> move lead to Closed.
Architecture Pattern
User builds sequence in UI -> stored in Supabase sequences table -> cron job checks scheduled_at timestamps -> fires Twilio API -> delivery status webhook updates message row -> inbound reply webhook appends to inbox feed -> Kanban reads lead stage from Supabase.
Data Model
User has many Leads. Lead has many Messages. User has many Sequences. Sequence has many SequenceSteps. SequenceEnrollment links Lead to Sequence with current step index.
Integration Points
Twilio for SMS and WhatsApp sending and receiving, Supabase for database and auth, Stripe for subscriptions, Resend for trial expiry email alerts, Vercel Cron for sequence scheduling.
V1 Scope Boundaries
V1 excludes: team seats, CRM integrations, voice calls, AI-generated message suggestions, email sequences, mobile app.
Success Definition
A local business owner with no technical background imports a lead list, sends their first sequence, and converts a paying customer — all without contacting the founder.
Challenges
WhatsApp Business API approval and Meta template pre-approval are the real blockers — not code. Getting the first 10 customers via cold outreach to local business Facebook groups requires 3x more time than building the product.
Avoid These Pitfalls
Do not build two-way WhatsApp without pre-approved message templates or Meta will ban the number within 24 hours. Do not skip TCPA opt-in UI or your first enterprise customer will create a legal liability. Finding the first 10 paying customers takes 3x longer than building — start cold outreach before the product is finished.
Security Requirements
Supabase Auth with email magic link. RLS on all tables scoped to user_id. Twilio webhook signature validation on inbound handler. Rate limit sequence sends to 100/hour per user. GDPR deletion endpoint required.
Infrastructure Plan
Vercel for Next.js and API routes and cron. Supabase for Postgres and auth. Twilio for messaging. Sentry for errors. GitHub Actions for deploy on push to main.
Performance Targets
CSV import of 500 rows under 3 seconds. Inbox feed loads under 1 second. Cron latency for sequence sends under 5 minutes from scheduled time.

First Run Experience
On first run: dashboard shows 5 pre-seeded demo leads in Kanban and a sample 3-step sequence already built. User can immediately: click Activate on the demo sequence and see a simulated send log populate. No manual config required: Twilio runs in sandbox mode for demo sends with no API key needed from user.
How to build it, step by step
1. Define Supabase schema for leads, sequences, sequence_steps, enrollments, and messages tables with RLS policies. 2. Run npx create-next-app and install Twilio SDK, Supabase JS, Stripe SDK. 3. Build CSV import page with Papa Parse client-side and batch upsert to Supabase. 4. Build sequence builder UI with v0 — drag steps, set delay in days, compose message body. 5. Implement app/api/send/route.ts that reads next pending enrollment step and fires Twilio.messages.create(). 6. Set up Vercel Cron at /api/cron/sequences to run every hour and trigger due steps. 7. Implement Twilio webhook handler at /api/webhook/twilio to capture inbound replies and append to messages table. 8. Build Kanban board component reading lead stage from Supabase with drag-to-update. 9. Add Stripe checkout for $39/month plan with trial period and usage metering for SMS overage. 10. Verify: import a 5-row CSV, activate a sequence, confirm Twilio sends message 1 immediately and schedules message 2 for 2 days later without any manual trigger.
