The operating layer

Spend day one on what matters.

Not on wiring up software. Day0 stands up your books, money, and back office from day zero — and runs the whole operating layer underneath, so you can do the work only you can do.

Built by the team that's automated work across 10 industries — aerospace to finance.

Most founders think about the back office in year two.

By then it's a mess to clean up. You're deep in the work you love — building, selling, shipping — and bookkeeping, expenses, payroll, and the right tools all wait until they become a fire.

The pieces all exist. Every one of them has an API. But stitching them into something that actually runs is a second job you never signed up for.

Why trust us

We've done this in the hardest places first.

  • 01

    We've automated real operations across 10 industries — manufacturing, aerospace, finance, and more.

  • 02

    That experience taught us what actually holds up in production — and what quietly breaks.

  • 03

    Day0 packages that systems knowledge into a proven path, so you start on rails instead of guesses.

How it works

You don't assemble anything. It assembles itself.

Day0 sits between you and every tool you'll ever connect. You bring the idea; it brings the proven path.

  1. 1

    Tell it what you're building

    A sentence is enough. No spreadsheets, no setup calls.

  2. 2

    It picks the proven stack

    The right tools for your kind of business — chosen from what we know works.

  3. 3

    It wires everything together

    Money, books, comms, growth, ops — standing up as one system from day zero.

  4. 4

    It runs, and gets better

    The agent handles each function and asks you only on the exceptions.

Beyond the stack

Not just a stack. A running operation.

Day0 doesn't stop at choosing your tools. It hands you a clear plan and the workflows that make a business run — built on golden-standard SOPs for your industry — then executes them across your connected stack. Once it's wired in, every function is operational, and the agent acts on it for you.

Each workflow is a live action the agent runs across your tools — not a doc that sits in a drawer.

Money & books, from day 1

The boring stuff that quietly sinks companies.

Bookkeeping, expenses, and cash aren't a cleanup job for later — Day0 wires them in before your first transaction. You always know what came in, what went out, and how long the runway is.

It gets better

It doesn't just run. It learns.

Every function starts with a benchmark on day one. Day0 watches each against its target and tunes it — so the same work runs better next month than this one.

Day one is the baseline. The loop only pushes it forward.

Start at zero

Tell us what you're building. We'll stand it up.

One sentence is enough. Day0 will show you the stack, wire it together, and run the business underneath — so you can get back to the part only you can do.
