Vaultbox
From Sketch to $500K ARR

We partnered with a solo founder and two compliance experts to design and build an end-to-end encrypted file storage platform that achieved SOC 2 Type I in just 4 months and hit $500K ARR within the first year.

Challenge

A Solo Founder's Compliance Problem

The Situation

David Kim is a compliance expert with deep domain knowledge in healthcare, legal, and financial regulations. He had a clear vision for a product: an encrypted file storage platform that actually understood HIPAA, SOC 2, and regulatory requirements.

But he had no tech team. He had a Figma sketch, a business plan, and zero technical infrastructure. He needed a production-ready platform that could handle HIPAA-regulated data, pass SOC 2 audits, and be simple enough for non-technical users.

Oh, and the budget was tight for a pre-seed startup.

Security First

End-to-end encryption wasn't optional. Client-side key management required proper cryptography implementation.

Regulatory Complexity

HIPAA compliance, SOC 2 readiness, audit logging, and data retention policies had to be built from day one.

Time Constraints

Market window was tight. MVP needed to launch in weeks, not months, to validate with early customers.

Process

From Sketch to Production

We took a structured approach to turn a Figma sketch into a SOC 2-ready platform. Each phase was compressed but intentional.

Discovery & Architecture

Week 1: Compliance requirements audit, security model design, infrastructure planning

Design System

Week 2: Visual language, component library, flow design, accessibility review

Core Build

Weeks 3-4: Backend API, encryption service, database schema, AWS infrastructure

Frontend & Launch

Weeks 5-6: UI implementation, onboarding, integrations (Stripe), QA, deployment

Core Pillars

Security & Compliance by Design

Vaultbox wasn't engineered to pass audits after the fact. Compliance was built into the product architecture from day one.

End-to-End Encryption

AES-256 encryption with client-side key management. Users control their encryption keys—not even Vaultbox has access to plaintext files. Keys are derived from user credentials and never leave the client.

AES-256

HIPAA Compliance

Business Associate Agreement (BAA) ready. All infrastructure on HIPAA-eligible AWS services. Audit logging captures all access, modifications, and deletions. Encryption at rest and in transit.

HIPAA Ready

SOC 2 Type I

Achieved 4 months post-launch. Granular access controls, role-based permissions, comprehensive audit trails, and documented security procedures. Type II certification in progress.

Solution

Product Features & Architecture

  • Team Workspaces Collaborate securely with granular permission controls. Share files with specific team members or entire workspaces.
  • Audit Logging Every action logged. Who accessed what, when, and from where. HIPAA-compliant audit trail for compliance teams.
  • Data Retention Policies Automatic deletion schedules. Set retention policies at file or folder level. Compliance-mandated data lifecycle management.
  • Version History Encrypted version control. Restore previous versions of files. Protect against ransomware and accidental deletions.
  • Single Sign-On SAML 2.0 and OAuth 2.0 support. Integrate with Okta, Azure AD, or your identity provider.

Security architecture
  • Automated Compliance System generates SOC 2, HIPAA, and GDPR reports. Dashboards for compliance officers. Built-in evidence collection.
  • Transparent Encryption Users never think about encryption. It happens automatically on upload. Simple UX, uncompromised security.
  • Granular Permissions Role-based access control (RBAC). Can/cannot view, edit, delete, or share. Perfect for regulated industries.
  • Two-Factor Authentication TOTP and hardware security key support. Optional for users, mandatory for admins.
  • Mobile Apps Native iOS and Android apps. Files encrypted on-device. Full-featured mobile experience.
