A web app that provisions and manages isolated tenant databases for early-stage SaaS teams without dedicated infrastructure engineers
Early-stage SaaS teams hit a painful inflection point when enterprise prospects demand data isolation: row-level security in a shared DB is cheap but leaky, while per-tenant database instances require DevOps expertise most founding teams do not have. This app sits between those two extremes, letting a two-person team provision isolated Postgres instances per tenant, run schema migrations across all of them, manage connection pools, and enforce access controls, all from a single dashboard without writing infrastructure code. The result is enterprise-grade data isolation without a dedicated platform engineer.

Gap Assessment
3 tools exist (Fortress, Nile, Supabase) but gaps remain: Requires the team to bring their own cloud account and manage underlying infrastructure costs; no managed hosting option for teams that do not yet have cloud accounts or want a fully hosted path; early-stage product with limited ecosystem integrations; Opinionated platform lock-in (Nile-hosted only, not BYOC); limited migration tooling for teams moving from an existing Postgres setup; $11.6M seed from Benchmark suggests early-stage with limited enterprise track record.

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| Fortress | BYOC orchestration platform that provisions isolated per-tenant databases in the customer's own cloud, handles migrations, connection management, and RBAC across instances | Requires the team to bring their own cloud account and manage underlying infrastructure costs; no managed hosting option for teams that do not yet have cloud accounts or want a fully hosted path; early-stage product with limited ecosystem integrations |
| Nile | Serverless Postgres purpose-built for multi-tenant SaaS with virtual tenant isolation, per-tenant backups, and placement on shared or dedicated compute; virtualizes tenant isolation at the DB engine level so teams avoid row-level security complexity | Opinionated platform lock-in (Nile-hosted only, not BYOC); limited migration tooling for teams moving from an existing Postgres setup; $11.6M seed from Benchmark suggests early-stage with limited enterprise track record |
| Supabase | Open-source Firebase alternative built on Postgres; provides Row Level Security policies for tenant isolation in shared databases; has a B2B SaaS solution page | RLS-based isolation is shared-schema only and requires significant custom code to be air-tight; per-tenant dedicated instances require manual Supabase project spinning and no cross-project migration or schema sync tooling; isolation is a side feature, not the core product |
