B2B Sales Intelligence Chrome Extension
Budget: $750 – $1,500 USD
Hello,
I’m looking to hire an experienced developer to build a **B2B sales intelligence Chrome extension**, similar in category to tools like Hunter or Apollo, but with a **leaner MVP scope** focused on validation and fast launch.
This will be a **freemium + subscription-based product** aimed at marketers, agencies, recruiters, and sales professionals.
---
## Project Overview
The product is a **Chrome extension** that helps users:
* discover and enrich business contact information (e.g. emails, company data)
* save and organise leads
* export data for outreach
* upgrade to paid plans for higher limits and advanced features
The extension is the **primary product**. A large standalone SaaS dashboard is *not* required for the MVP.
---
## Core Features (MVP Scope)
### 1. Chrome Extension (Manifest V3)
* Works on supported pages (e.g. LinkedIn, company websites, public business pages).
* Injects a clean UI panel or button.
* User-triggered actions only (no background scraping).
---2. Lead / Contact Lookup
* Extract basic public data from the current page (company name, domain, role, etc.).
* Enrich data via third-party APIs (email discovery / verification / enrichment).
* Display results clearly inside the extension.
---3. Save & Manage Leads
* Users can save leads to a simple list.
* Tag or label leads.
* Basic lead history (no complex CRM required for MVP).
---4. Usage Limits (Freemium Model)
* Free plan:
* Limited number of lookups per month.
* No bulk actions.
* No exports.
* Paid plans:
* Higher lookup limits.
* CSV export.
* Bulk actions (optional for MVP, depending on effort).
--- 5. Payments & Subscriptions
* Subscription-based monetisation.
* Prefer **Stripe Checkout** or **ExtensionPay** (open to recommendation).
* Monthly pricing tiers (e.g. Pro / Team).
* Extension must:
* detect paid users
* unlock paid features
* enforce usage limits for free users
--- Technical Requirements
**Required**
* Chrome extension development (Manifest V3)
* JavaScript or TypeScript
* API integrations (enrichment / email discovery services)
* Backend or serverless setup for API calls and usage tracking
* Stripe or ExtensionPay integration
**Nice to Have**
* Experience with B2B SaaS or lead-gen tools
* Prior Chrome Web Store submissions
* Clean, scalable codebase
-- Privacy & Compliance
* Use only public, user-visible data.
* No scraping behind login walls.
* No automation without user action.
* Chrome Web Store–compliant permissions.
* Clear separation of client-side and server-side logic (API keys kept server-side).
---Deliverables
* Fully working Chrome extension (MVP)
* Source code
* Setup and deployment instructions
* Support during Chrome Web Store submission
* Basic documentation for future development
