Auth, sessions, roles, and row-level security — multi-tenant from day one.
Your life has themes. Your apps have vendors. Technology is organized around who sells it; your week is organized around home, work, community, focus, and the things worth remembering. Rumble Built builds one product per theme — each worth choosing on its own — on one context you own, so you decide how they relate. CapturedIt is where your context enters.
rumble v. to make a continuous deep, resonant sound — we use that as a metaphor for systems that stay steady when work piles on, not just when the demo is quiet.
Every theme works on its own and without AI. Where assist exists it is optional, budgeted, and rollback-able.
Why one product per theme, and not one app. A household calendar should not look like a firm’s revenue recognition. Each theme is a different job with a different shape, so each gets a dedicated product — strong enough to stand alone, and sold that way. What they share is Context Hub: the one context you own, visible in whichever themes you turn on, never in the ones you don’t.
The five themes today — each its own brand: Memory — CapturedIt: capture once, use anywhere; where your context enters. Focus — Premodoro: focus stays, info comes to you. Home — HuniDu: the household, run like an operator would. Work — Bread & Butter: operations for project-based firms. Community — nMyCity: civic intelligence from your block to the nation.
Under every theme is Rumble Rails — the production stack we built once so a new theme takes a quarter, not a year. Teams can run on it too, through Rumble Built Services. Follow what ships on the Shipping log.
For a person: one flyer, one receipt, one notice — captured once, placed in the scope you choose, visible only in the themes you turn on. For a firm: a shared library with seats and roles, running in parallel to each member’s own. Flip the switches; compare it to how your apps work today.
What every Rumble product shares underneath — built once as Rumble Rails so the next theme costs a quarter, not a year. Status is stated honestly on the Rail Map.
01 · IDENTITY
Auth, sessions, roles, and row-level security — multi-tenant from day one.
02 · BILLING
Subscriptions, seats, plan gating, and usage metering — Stripe-native, shared by every product.
03 · SIGNALS
Events, errors, and the dashboards that see problems before support does.
04 · AI
Provider routing with budgets, timeouts, fallbacks, and a rollback plan. Optional in every product; governed in all of them.
05 · CONTEXT
The one context you own, powered by CapturedIt — shared across the themes you turn on; personal, household, firm, and community scopes kept separate.
Three commitments that hold whether we’re building a simple page or a complex system.
Security, tests, and clean deployments are the baseline — not the stretch goal. Anything that touches your customers starts there.
Opt-in first. When a model is in the stack, it ships with budgets, timeouts, and a rollback plan. We build for the day it breaks, not the demo where it doesn’t.
Problems should show up in dashboards before they show up in support tickets. We wire that in early — not after the first incident.
Practical promises — the kind you can hold us to.
