Frequently Asked Questions from SaaS Founders
Straightforward answers regarding database tenancy, pricing, IP ownership, and VC due diligence.
How does Xharvoc ensure tenant isolation in multi-tenant SaaS applications?
We engineer multi-tenancy using PostgreSQL Row-Level Security (RLS) via Supabase or isolated database schemas. Every query is cryptographically bound to the authenticated user's organization UUID, making cross-tenant data leaks mathematically impossible at the database engine level.
Who owns the intellectual property and code of our SaaS application?
You do. 100% of the code, database schemas, Docker files, and infrastructure scripts are assigned to your company upon milestone completion. We never retain proprietary locks or licensing claims over client code.
Can you help our SaaS pass technical due diligence for seed and Series A fundraising?
Yes. Every SaaS platform we build includes a comprehensive Technical Due Diligence Dossier: complete entity-relationship diagrams (ERDs), API contract specifications, security audit logs, data retention policies, and CI/CD automated test suites that satisfy UK and European venture capital technical auditors.
What is the typical investment range for building a custom SaaS platform?
An 8-week fixed-scope SaaS MVP typically ranges from £15,000 to £35,000. Complex enterprise-tier SaaS platforms with custom billing matrices, multi-tiered organizations, and extensive integrations range from £35,000 to £65,000 across structured two-week agile sprints.
