An operations room at night: one figure before a wall of glowing monitors
Marga Haus · Tanuj Ruhal · Operator by the month · Melbourne, working globally

The operator founders and heavy industry call in.

Engineer, ex-Accenture and Aurecon, founder of three ventures. I make the decision, build the case, ship it, then hand it to your team.

Two rooms. Pick yours.

One operator, two very different rooms. Each has its own page and proof.

Worked with

Through consulting engagements and direct work.

What happens in the first thirty minutes.

A stuck decision costs you every month it slips. The call is free, needs no prep, and ends with a next step.

  • You name the stuck thing

    The decision that keeps slipping, the case the board won’t sign, the product that won’t ship. In your words and numbers.

  • I say how I would attack it

    Where I’d look first, what I’d measure, and what two weeks would produce. Out loud, on the call.

  • You leave with a next step

    Sometimes the call is enough. If it needs the diagnostic sprint, we book two weeks.

How it works

Diagnose the decision. Stay for the work. Leave it with the team.

One four-stage engagement for both worlds. Senior operating capacity, only while it builds yours.

Stage 01

Frame the decision

Free. Bring the stuck decision. We name the owner, the constraint and the missing evidence. Often you leave with the next move.

30 minfree, no prep

Stage 02

Prove what is true

Two weeks inside the numbers, people and operations. Ends with a decision brief: evidence, options, a recommendation and the first 90 days.

2 weeksfixed evidence sprint

Stage 03

Build it into the work

I stay by the month with the accountable owner: build the model, run the decision rhythm, move the product. Scope follows the sprint.

Stage 04

Transfer it and leave

It ends when a named owner can run the model, decisions and rhythm without me. Usually three to nine months.

Meet Tanuj.

I’m Tanuj Ruhal. Mechanical engineer, former Tier-1 consultant, founder of Ramp Up, MedClear and MVP Guru. Melbourne-based, working globally.

I’ve led product for a global energy major: eight products shipped with a team of up to 16. I’ve led the modelling of $100M+ in savings for an iron ore miner, and $65M+ in fleet cases.

Marga Haus is that experience by the month: diagnose, model the case, ship, run the rhythm, then hand it over.

Questions people ask first.

The short answers. The call covers the rest.

What does an operator by the month actually do?

Joins your leadership for a few days a month and owns the outcome: the decision, the case, the product, the cadence. Then hands it to your team.

How is that different from hiring a consultant?

An operator carries the recommendation through inside your own cadence: the meeting, the model, the release. The engagement is measured by what changed in the business.

What does it cost?

The call is free. The two-week diagnostic sprint is priced before it starts. The retainer is scoped after it. With founders, part is usually equity.

How long does an engagement last?

Typically three to nine months. The retainer ends when your team can run the rhythm without me, whatever the calendar says.

Do you work outside Melbourne?

Yes. I am based in Melbourne and work globally, on site where the problem needs it.
