Ship faster with a real foundation

There's a moment every SaaS hits a few months in. The demo works, users are showing up, and then someone asks for the boring stuff: usage-based billing, a retry-safe background job, an audit trail. Suddenly you're not building your product — you're rebuilding infrastructure you should never have had to write.

LaunchSoku exists to delete that moment.

The cost of starting from a blank file

A starter kit that gets you to "hello world" is solving the easy 10%. The expensive 90% is the stuff that only shows up under real load and real money:

Concern	Looks easy	Actually needs
Billing	A Stripe checkout	Webhooks, proration, dunning, tiers
Background jobs	setTimeout	Durable retries, idempotency, backoff
Observability	console.log	Traces, error grouping, alerting

Each row is weeks of work and a long tail of edge cases. None of it is your product.

What "a real foundation" means

The foundation is opinionated where it should be and out of your way everywhere else. A new billable feature is a few lines, not a new subsystem:

import { withEntitlement } from "@launchsoku/billing";

// Gate a route behind a paid tier. Webhooks, proration, and the
// "no active subscription" path are already handled upstream.
export const POST = withEntitlement("pro", async (req) => {
  const result = await runExpensiveJob(req);
  return Response.json(result);
});

The goal isn't to write less code. It's to never write the same dangerous code twice.

The math changes

When the foundation is solid, the cost of a feature drops to the cost of the feature — not the feature plus its infrastructure tax. That's the whole pitch, and it compounds with every release.

That's what we're building. The rest of this blog is the receipts.
