B2B SaaS
Gryso — Technical Due Diligence Pass
Architecture hardened and passed technical due diligence; Series A conversations unlocked.
What We Were Asked to Solve
Gryso had a working B2B SaaS product but was stalling in fundraising — investors kept flagging technical risk. The codebase lacked test coverage, had weak authentication, no audit logs, and the database schema could not support multi-tenancy at the scale required for enterprise customers.
5-Step Engagement Framework
Technical Forensic Call
Identified the 5 critical technical gaps investors were surfacing in due diligence reviews.
Architecture Audit & Blueprint
Designed a multi-tenant data model, auth hardening plan, and test pyramid strategy to hit institutional-grade coverage.
System Hardening
Implemented Row Level Security in Supabase, rebuilt auth with full audit trails, and introduced CI/CD with automated test gates.
High-Velocity Sprints
Delivered test coverage from 0% to 72%, migrated to multi-tenant schema with zero data loss.
Hardened Handoff
Produced a complete technical due diligence dossier: architecture docs, security posture report, and test coverage report.
Technologies Used
Next.js · Node.js · Supabase (PostgreSQL + RLS) · Vercel · Vitest · Playwright
Measurable Outcomes

“After months of investor hesitation around our tech stack, Zenveus came in and gave us a codebase we’re proud to show anyone. We passed technical DD on the first pass after their engagement.”
