StockTalk SA: Building a Real-Time JSE Community Platform from Scratch
South Africa's first real-time JSE community platform — live prices, AI digests, and Stripe-billed Premium.
Cloud Forces took StockTalk SA from concept to production as a full-stack, cloud-native web application — live JSE price feeds for 340+ equities, a proprietary Sentiment Index, Stripe-billed Premium tier, AI-generated email digests, and an AWS production stack managed 24/7.
The Challenge
South African retail investors lacked a dedicated platform for discussing JSE-listed stocks. Options were fragmented — scattered across WhatsApp groups and generic social media — with no real-time market data, structured sentiment tracking, or subscription monetisation. The client needed a purpose-built, production-grade platform from the ground up.
What Cloud Forces Built
Cloud Forces delivered stocktalk.co.za end-to-end — product design, full-stack engineering, cloud deployment, analytics, and ongoing production operations.
Real-time JSE Price Engine
Live price feeds for 340+ JSE-listed equities, updated continuously during trading hours.
Community & Sentiment Platform
Per-stock discussion feeds with a proprietary StockTalk Sentiment Index tracking crowdsourced bullish/bearish signals.
Premium Subscription Tier
Stripe-integrated billing unlocking watchlists, portfolio tracking, director dealings alerts, and data exports.
AI Email Digest System
Three automated daily and weekly market digests generated by the Claude API and delivered via SendGrid.
Analytics & SEO
GA4 and PostHog instrumentation, SSR pages with JSON-LD, Open Graph tags, and a POPIA-compliant privacy policy.

VPC-secured hosting on EC2, managed RDS PostgreSQL, S3 asset storage, CloudWatch monitoring, and a CI/CD pipeline.
