For B2B SaaS founders
Engineering for
B2B SaaS Founders
B2B SaaS MVPs that skip multi-tenant, SSO-ready architecture, and audit logging at v1 always pay the cost later — usually right when the first enterprise customer asks for them. We ship that infrastructure from commit one because it's cheap then and expensive later.
B2B sales cycles are months. The product that closes the first enterprise has to exist before the procurement conversation starts. Every week of slippage on the build pushes the cash event by a month.
Stack we use
Compliance
SOC 2-friendly defaults. We won't manage the audit itself but we'll ship the technical controls (audit logs, access reviews, change management) that the auditor will check.

Why b2b saas builds are different
Same engagement model.
Industry-specific defaults.
We don't pretend a generic SaaS stack ships b2b saas at v1. The pain points below are what most builds in your industry get wrong on the first try — we wire them correctly from commit one.
The pain points
What breaks at v1 in b2b saas
Each of these is something we've watched founders get wrong on the first build. We ship the correct version on day one.
01
Multi-tenant from day one
Single-tenant code with a tenant_id bolted on later is a rewrite, not a refactor. We default to row-level isolation in Postgres RLS from the first table.
02
Stripe billing with real edge cases
Webhooks, dunning, proration, mid-cycle plan changes, usage metering. The 20% of billing logic that 80% of MVPs skip and customer support gets to debug forever.
03
SSO-ready before the first enterprise asks
WorkOS or Clerk hooked up from the start. Adding SAML / OIDC after you've shipped 6 months of code with assumed-email-login takes weeks.
04
Admin tooling for actual operations
Customer admin (workspace settings, members, billing portal). Internal admin (you, looking at customer health, debugging issues). Most MVPs ship the first and skip the second; you debug in psql for a year.
What we ship
Concretely,
by handoff.
