Overview
Sproute is an AI-powered prospecting tool built for freelancers who rely on WhatsApp to find and close clients. Instead of manually searching for leads and drafting messages one by one, users get AI-assisted outreach: draft messages, reply handling across multiple tones, and automated follow-up sequences that still sound like a real person. The product is designed to remove the busywork from cold outreach while keeping every message human.
The Problem
Freelancers spend hours finding leads and writing outreach messages, and most of that effort gets lost to silence or generic-sounding follow-ups.
- Manually searching for prospects is slow and inconsistent
- Writing outreach messages from scratch takes time and often reads as generic
- Follow-ups get forgotten or feel robotic when automated
- Handling replies across many conversations at once is hard to manage
The Solution
Sproute combines AI-assisted messaging with a structured outreach flow so users can prospect and follow up without losing the human touch.
- AI-assisted lead discovery and message drafting
- Reply handling across nine common scenarios, each with tone-specific templates
- Automated no-reply follow-up sequences
- A WhatsApp-style chat helper for managing conversations
- Subscription billing handled through Paystack

UX Strategy
"Tone-specific reply templates"
A single generic tone does not fit every lead, so users can match the conversation style that fits the client.
"Open location search instead of hardcoded cities"
Removing hardcoded Nigerian cities and geocoding suffixes lets any user worldwide prospect in their own area.
"Server-side API keys"
Moving Gemini and search API keys server-side closed a security gap found during development.
"WhatsApp-style chat interface"
A familiar chat layout reduces friction for users already used to WhatsApp.
