CareConnect Health, a US-based HealthTech startup, had validated their concept — a care coordination platform connecting primary care physicians, specialists, and patients — with a MVP built on a no-code tool (Bubble.io). The Bubble MVP had served for validation but was hitting serious performance walls at 500 concurrent users, couldn't be made HIPAA-compliant (required by their hospital system clients), and had no viable path to the AI-powered care pathway recommendations that were central to their Series A pitch. The founder needed a complete rebuild on a production-grade, HIPAA-compliant stack within 5 months — before their Series A raise — and the rebuild had to be done without disrupting the 1,200 existing platform users.
We built a new HIPAA-compliant platform from scratch on a modern stack with zero downtime migration from the Bubble MVP. The platform included a care coordination dashboard for physicians, a patient-facing mobile app, secure messaging between care team members, AI-powered care pathway recommendations using GPT-4o with clinical decision support guardrails, and a real-time care event notification system. All data handling was built to HIPAA technical safeguards, with Business Associate Agreements in place for all sub-processors.
Next.js 15 frontend with server-side rendering for SEO and performance
React Native mobile app (iOS + Android) for patient-facing features
Node.js/Express API with PostgreSQL on AWS RDS (encrypted at rest with AES-256)
HIPAA-compliant AWS infrastructure: VPC isolation, CloudTrail logging, WAF, GuardDuty
AWS HealthLake for FHIR-standard clinical data storage and exchange
OpenAI GPT-4o with custom clinical guardrails for care pathway AI (no ePHI sent to OpenAI)
Twilio for secure messaging with end-to-end encryption
Audit logging service with tamper-evident logs for all PHI access events
“Canny Technologies delivered the impossible: a complete platform rebuild in 5 months, HIPAA-compliant, with zero downtime for our existing users. The new platform was the centrepiece of our Series A deck. We closed the round at $12M, and the lead investor specifically called out the technical infrastructure as a differentiator. We're now at 8,000 active users and the platform has never had a performance issue.”
— Dr. Sarah Chen, CEO and Co-Founder, CareConnect Health
The rebuild enabled CareConnect to close a $12M Series A — impossible with a Bubble MVP. The platform now serves 8,000 active users across 14 hospital systems with 99.99% uptime. The AI care pathway recommendations have been validated in a pilot study showing 23% reduction in unnecessary specialist referrals. Full HIPAA compliance enabled the first enterprise hospital system contract worth $1.8M ARR.
