Client Overview
Paratus Health is a Y Combinator-backed startup building AI-powered voice agents to automate patient onboarding and post-visit documentation. With a lean, technical founding team based in San Francisco, they set out to transform clinical workflows across healthcare systems.
The Challenge
Paratus built an MVP to secure funding, but rapid early development led to a brittle, undocumented codebase. With only two engineers, they faced critical hurdles:
- Unscalable Foundation: Legacy code slowed development velocity and created tech debt.
- Team Bandwidth Limits: Resource-strapped team couldn’t keep up with investor-driven features and demo schedules.
- Time-Critical Iterations: High-pressure deadlines for fundraising and customer traction demanded rapid feature rollout.
Spartan’s Solution
Spartan deployed a senior engineering pod designed to move at startup speed. From day one, we worked in lockstep with Paratus’s CTO, translating product requirements into production-grade software.
- Team Deployment: Began with 2 engineers, scaling to 3 as needs grew.
- Backend Refactor: Rebuilt core infrastructure from Node.js to NestJS for better scalability and maintainability.
- Frontend Portals: Delivered secure, responsive interfaces for patients and brokers, integrated with HIS/EHR systems.
- AI Workflow Engine: Built HIPAA-compliant agents to automate 99% of intake and documentation tasks.
- Developer Process:
- Interpreted PRDs, created RFCs, and handled end-to-end implementation.
- Shipped critical features in 3–14 day cycles aligned to investor and partner demos.
- Ran daily standups, async collaboration, and continuous delivery.
Key Deliverables
- Codebase Rewrite: Clean slate migration of the backend to improve velocity and reduce tech debt.
- Third-Party Integration: Embedded Athena EHR, billing APIs, and more into the core workflow.
- Rapid Feature Delivery: Enabled same-week delivery of complex functionality for time-sensitive demos.
- Demo Enablement: Supported investor presentations with fully working product flows.
Results
- 2.3M Seed Raised: Closed within two weeks post-YC, enabled by stable demos and product progress.
- 2x Engineering Velocity: Spartan doubled the effective team size with minimal onboarding overhead.
- 50% Faster Ship Cycles: Agile execution significantly outpaced industry benchmarks.
- Scalable Codebase: Set foundation for long-term growth and future product lines (e.g., AI fraud detection).
Before vs After Spartan
| Metric | Before Spartan | With Spartan |
|---|---|---|
| Codebase | Messy, unscalable MVP | Clean, modular NestJS architecture |
| Engineering capacity | 2 in-house devs | Doubled capacity with senior support |
| Feature delivery cycle | 2–4 weeks | 3–10 days |
| Time spent on demo prep | Ad hoc, high-stress | Automated, reliable, demo-ready |
| Fundraising impact | Uncertain timelines | $2.3M raised within 2 weeks post-demo |
Why Paratus Chose Spartan
Paratus didn’t need a traditional IT vendor. They needed a startup-native partner who could ship like a founding engineer and think like a product owner.
Spartan’s Edge
- Immediate value from day one with zero onboarding lag
- Engineers who understand trade-offs between velocity and scale
- Engineering craftsmanship that holds up under pressure
- Flexible, async collaboration across time zones
- SF-quality talent at a fraction of the local cost
What’s Next
- Phase 2 Expansion: Adding AI-powered fraud detection modules.
- Team Growth: Continue scaling alongside Spartan to meet growing client and partner demand.
