B2B SaaS MVP Launch — Case Study
The Challenge
An early-stage European B2B team had validated problem-solution fit through interviews but had no shippable product. They needed to go from zero to a paying-customer-ready MVP in a single funding window — with user onboarding, subscription billing, core workflow features, and analytics instrumentation so they could measure activation and retention from day one.
Previous agency quotes assumed six-month timelines and oversized teams. The founders wanted a partner who could make pragmatic scope cuts without compromising the architecture needed to grow into a full SaaS platform. Stripe billing, team invites, and a clean onboarding funnel were must-haves; nice-to-haves like advanced reporting and integrations were explicitly deferred to post-launch.
They had ten weeks before a committed beta cohort of twelve companies expected access.
The Solution
Xeverse ran a product-led MVP sprint: week one for scope and architecture, weeks two through eight for iterative builds with weekly demos, and weeks nine and ten for hardening, billing QA, and beta onboarding support.
We built on Next.js with a Node.js API and PostgreSQL, using a modular monolith structure that separates auth, billing, and core domain logic for future service extraction. Stripe Checkout handles subscription creation; webhooks sync plan status to the database and gate feature access automatically.
The onboarding funnel guides new organizations through workspace setup, team invites, and a guided first-action tutorial that drives activation. We instrumented key events — signup, invite sent, first workflow completed — with analytics hooks ready for Mixpanel or Amplitude integration.
Core workflow features were scoped to the minimum viable path their beta users confirmed in discovery calls. Admin settings cover profile, billing portal links, and team role management. Error boundaries, loading states, and email notifications polish the experience for paying customers.
We deployed to production with environment separation, database migrations, and a runbook for the founding team. All twelve beta companies onboarded in the first week after launch. The codebase and architecture documentation positioned them to hire their first engineer and extend features without a rewrite.
“From architecture to release, Xeverse operated like an embedded product team. We shipped a production-ready SaaS MVP in weeks, not months.”
