Free tier: manual outreach only. Pro: $199/month per user, auto-triggers + intent signals. Enterprise: custom pricing with admin controls.

Competition Level

High

Estimated Monthly Cost

Crisp/LinkedIn proxy API: $40, Supabase: $25, Vercel: $20, Claude API: $50, Resend: $20, Stripe fees: 2.9% of revenue. Total: ~$155/month fixed + payment processing.

Revenue Potential

Build It Right

Core User Journey

Sign up → import prospect list → set outreach intent trigger → first message sent automatically → reply received → upgrade to Pro to scale.

Success Definition

A sales team activates the product, runs auto-sequences to 50 prospects, receives 8+ replies within 14 days, and upgrades to paid before trial ends.

Architecture Pattern

LinkedIn API monitors target profiles → intent signals stored in Postgres → Claude generates personalized message → message queued in Redis → delivered via LinkedIn or email → replies captured and stored → dashboard shows performance metrics.

Integration Points

LinkedIn API (via proxy), Crisp for activity monitoring, Claude API for personalization, HubSpot/Salesforce APIs for CRM sync, Stripe for billing, Resend for email fallback.

Data Model

SalesTeam has many Prospects. Prospect has many OutreachSequences. Sequence has many Messages. Message may have one Reply. Team has many CRMIntegrations.

Avoid These Pitfalls

Overusing LinkedIn API will trigger rate limits and account bans — implement exponential backoff. Do not generate generic messages or reply rates will tank and damage product reputation. Do not ignore GDPR consent — verify prospect opt-in status.

V1 Scope Boundaries

V1 excludes: multi-channel (email, SMS, Twitter), sales playbook templates, admin controls for enterprises, white-label.

Example Use Case

David runs a 5-person sales team at a B2B SaaS company. He sets up ProspectFlow to monitor 500 target prospects. When Marcus, a VP of Sales, changes jobs and joins Acme Corp (detected via LinkedIn), ProspectFlow auto-sends a personalized message: 'Hey Marcus, saw you joined Acme as VP of Sales. We just helped 3 similar orgs reduce their sales cycle by 40%. Worth a 15-min call?' Marcus replies within 24h. $50k deal follows.

Challenges

LinkedIn terms of service heavily restrict automation. Account bans are a real risk. Building enough intent signals without being labeled spam.

Success Metrics

Month 1: 40 teams sign up. Month 2: 25 paying teams, $5k MRR. Month 4: 80 paying teams, $15k MRR.

MVP Scope

Manual prospect upload, AI sequence generation, reply inbox, basic intent signals (job changes via public search), Stripe billing.

Launch & Validation Plan

Interview 20 sales leaders on cold outreach challenges. Build landing page with reply rate benchmarks. Recruit 10 beta teams for 3-week pilot.

Customer Acquisition Strategy

First customer: Cold email 30 B2B SaaS companies (Series A-B) with: 'We help sales teams get 40% more replies on LinkedIn cold outreach. 2-week free trial, no card required.' Ongoing: ProductHunt, Sales Hacker community, LinkedIn Sales Navigator groups, sponsorship of sales blogs (RevGenius, SalesHQ).

Competitive Advantage

Outreach.io and Apollo exist but lack real-time intent signals. ProspectFlow combines intent + personalization + LinkedIn native experience.
