What is it?

Sales teams spend 5 hours/week researching prospects and writing personalized LinkedIn messages. ProspectFlow watches LinkedIn signals (public API), identifies high-intent moments (new job, company news, post engagement), triggers contextual outreach sequences, and manages follow-ups. It's a BDR in software form.

Why now?

▸LinkedIn activity monitoring (job changes, promotions, engagement)
▸AI-personalized outreach sequence generation
▸Intent signal classification
▸Reply management dashboard
▸A/B testing for messaging
▸CRM integration (HubSpot, Salesforce)

Target Audience

B2B SaaS sales teams and agencies (15k+ teams globally). Early-stage startups (Series A-B) with 5 - 30 person sales teams.

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.

How do you build it?

Tech Stack

Next.js, Supabase, Stripe, Crisp API or LinkedIn API (via proxy), Anthropic Claude API for sequence writing, Resend for email fallback, Vercel - build with Lovable for UI, Cursor for automation logic.

Suggested Frameworks

Time to Ship

3 weeks

Required Skills

LinkedIn API integration, intent signal classification, email sequence automation, Stripe billing.

Resources

LinkedIn API docs, RocketReach for intent signals, HubSpot API for CRM sync, Anthropic Claude for personalization.

MVP Scope

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

Core User Journey

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

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.

Data Model

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

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.

V1 Scope Boundaries

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

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.

Challenges

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

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.
