How I secured $3M seed round by fixing critical HIPAA gaps

The client

• Industry: Healthcare SaaS Platform
• Stage: Pre-seed (4 months in development), closed $3M seed round 8 weeks after engagement
• Team: 5 people (2 backend, 1 frontend, 1 DevOps, 1 PM)
• Challenge: Critical HIPAA compliance gaps + unfocused roadmap burning runway
• Engagement: Fractional CTO for technical assessment and roadmap prioritization

The situation

What was broken:

• Critical security vulnerabilities - Authentication tokens stored in localStorage (accessible to XSS attacks), refresh tokens never rotated, session tokens never expired properly. Any script injection could exfiltrate credentials. In a HIPAA-regulated environment, this was a ticking time bomb.

• Unencrypted data at rest - Patient health information stored in databases without encryption. A single database breach would expose PHI for 100-150 users with no technical controls to limit the damage.

• No audit trail - Zero logging of who accessed what patient data when. HIPAA requires audit logs for all PHI access. They had no way to demonstrate compliance or investigate potential breaches.

• Feature creep was consuming resources - The team was building everything anyone requested. Current focus: implementing a custom HIPAA-compliant chat system with image moderation and translation features for clinician-to-clinician communication. Timeline: 3+ months of development effort, plus $500+/month in third-party service costs.

• Misaligned priorities - A 5-person team spending months on a chat feature while sitting on authentication vulnerabilities that could kill the company in due diligence.

Why they couldn’t solve it internally:

The team knew they needed “HIPAA compliance” but didn’t understand the difference between existential risks (insecure auth, unencrypted PHI) and nice-to-haves (built-in chat vs. external tools).

They were in “build mode” - executing on a feature list without a risk framework. No one was asking: “What could prevent us from raising our seed round?”

The stakes:

Seed fundraising was approaching. Any technical due diligence would immediately flag the authentication issues and unencrypted data. These weren’t “fix later” problems - they were “no term sheet” problems.

Beyond fundraising, they were burning limited pre-seed runway building features that didn’t address core platform value or regulatory requirements.

The approach

Week 1: Technical audit & risk assessment

I conducted a comprehensive security and compliance review:

• Reviewed authentication flow, data storage, and access patterns
• Mapped what constituted PHI in their system and where it lived
• Assessed current feature roadmap against business priorities
• Identified regulatory gaps vs. architectural debt

Critical findings:

• Existential risks: Insecure authentication, unencrypted PHI, no audit logs
• Expensive distractions: 3-month chat feature build when clinicians already communicate via standard tools
• The reality check: Doctors and nurses were already texting/calling on personal phones in real clinical settings

Week 2-3: Security remediation

Focused entirely on issues that would block fundraising or create regulatory exposure:

1. Fixed authentication (Week 2)

   • Moved all tokens from localStorage to httpOnly cookies (XSS protection)
   • Implemented proper token expiration and refresh rotation
   • Added secure session management with server-side validation
   • Protected against CSRF with token binding

2. Encrypted data at rest (Week 2)

   • Enabled database encryption for all tables containing PHI
   • Implemented field-level encryption for sensitive data
   • Documented encryption key management procedures

3. Implemented audit logging (Week 3)

   • Built comprehensive access logs for all PHI interactions
   • Created audit trail showing who accessed what patient data when
   • Set up log retention meeting HIPAA requirements (6 years)

Week 2-4: Roadmap reframing

Simultaneously worked with founders to reprioritize the feature roadmap:

The chat feature conversation:

• Their plan: Build custom HIPAA-compliant messaging system with third-party chat infrastructure ($500+/month), add image moderation, implement Spanish translation. Timeline: 3+ months.
• My question: “What are clinicians doing TODAY to coordinate care?”
• Their answer: “Personal phones, text messages, WhatsApp…”
• My recommendation: Acknowledge that inter-clinician communication happens on standard tools. Document the limitation. Focus dev resources on the features that MUST be compliant (patient data, clinical documentation). Plan proper secure messaging for post-funding when you have real usage data.

The prioritization framework I introduced:

1. Existential risks - Issues that block funding or create regulatory liability (FIX NOW)
2. Core value proposition - Features that prove the platform works (BUILD NOW)
3. Infrastructure features - Nice-to-haves that can wait for real user feedback (DEFER)

Results by week 4:

• All critical security issues resolved
• Team refocused on core platform features that demonstrated value
• Chat feature deprioritized, saved 3 months of development time
• Platform ready for both user validation and investor technical diligence

The results

Security & compliance transformation:

Development efficiency:

Business outcomes:

The decision framework: When to defer vs. when to build

Critical : Fix immediately (existential risks):

• Security vulnerabilities that could block fundraising
• Compliance gaps that create regulatory liability
• Data protection issues involving PHI/PII
• Authentication/authorization flaws

Essential : Build now (core validation):

• Features that prove your core value proposition
• Functionality users need to complete primary workflows
• Capabilities that differentiate you from alternatives

Optional : Defer until validated (infrastructure features):

• “Nice-to-have” features users aren’t requesting yet
• Complex integrations you can approximate with manual processes
• Built-in versions of things that work fine externally
• Features where you don’t yet have usage data to inform design

The chat feature was category Optional : Complex to build, expensive to operate, low signal about core platform value, and clinicians already had working alternatives.

The authentication issues were category Critical : Would kill the seed round and created real liability.

Sitting on critical security issues while building “nice-to-have” features?

Every week you spend building the wrong things is a week closer to failing technical due diligence or running out of runway.
