From 6-Hour Data Delays to Real-Time: How a B2B SaaS Company Got 127 People Using Analytics
A Series B SaaS company's analytics took 4–6 hours to refresh — and only 3 people had access. XCodeSol built a real-time platform that 127 employees now use daily.
Imagine waiting 6 hours for yesterday's sales numbers. That was reality for a Series B SaaS company — until XCodeSol built a streaming analytics platform with Kafka + ClickHouse delivering data in under 3 seconds.
Key Business Results & Performance Metrics
Client Challenges & Problem Scope
Stale Data, 3 Users, 7 Charts
A rapidly growing Series B SaaS company made strategic decisions on data that was 4–6 hours old. Their analytics queried production PostgreSQL — causing latency spikes for paying customers. Only 7 pre-built charts with zero drill-down. Only 3 executives had access. Answering 'which features drive upgrades?' took 6 weeks — a static PDF. A data-driven company that could not be data-driven themselves.
