Launch, 0 to 1

From the written concept to the first euro taken.

I have opened four restaurants, run a 1 500 m² venue in Lisbon and built two e-commerce businesses. Today I work with the people who have reached the moment where everything gets decided.

Opening a shop or a restaurant means handling six workstreams in the right order: concept validation, the business model, the premises or the platform, suppliers, hiring and the commercial launch. The most common mistake is signing the lease before the model has been checked.

Launch support exists so that those calls are made with someone who has made them before, and so that the decisions which will be expensive to undo after opening are spotted beforehand.

01 / Method

The six workstreams of an opening.

An opening is not won on the quality of any single one of these workstreams, but on the order in which they are handled. Every row in the table reads as a decision to make, not as a task to tick off.

Workstream What gets decided The classic trap When to handle it
Concept and positioning Who you sell to, what you sell, and the reason someone would come to you rather than to the place two streets away. Opening without having tested the offer on real customers who pay, taking the enthusiasm of friends and family for market validation. Before any financial commitment, and before even looking at premises.
Business model and margins Prices, cost of goods, payroll, the rent you can carry, the break-even point and the cash needed in the first months. Underestimating the working capital needed in the first months, by building a plan that holds at cruising speed but not during the ramp-up. Right after the concept, before the search for a site, because it is the model that says what rent you can carry.
Premises or platform Location, footfall, floor area, technical feasibility, the length and the clauses of the lease, the fit-out budget. Online, the equivalent: the platform, logistics and the cost of acquisition. Signing a lease before the model exists, because the site was appealing and another applicant was circling. Once the model is written and costed, never before.
Suppliers and purchasing Sourcing, purchase terms, lead times, minimum order quantities, stock levels and fallback options. Depending on a single supplier for a core product, and discovering the problem in the first week it runs out. During the fit-out, with samples tested and terms in writing.
Team and training The real day one org chart, the key roles, job descriptions, rotas, hiring and training before opening. Hiring too late, then opening with a team discovering the menu and the processes in front of the first customers. As soon as the opening date is set, keeping time to train before the first service.
Commercial launch Local and online visibility, the business listing, reviews, neighbourhood relationships, the list of first customers and the rhythm of the first weeks. Overlooking the cost of acquiring the first customer, counting on passing trade and word of mouth to fill the place from day one. Alongside the fit-out, so that you open with an audience already built.

02 / Reality

What a mistake costs at each stage.

Not all mistakes weigh the same. Some are fixed in a week, others are carried all the way to closing down. Here are the three that cost the most, and the signal that lets you see them coming.

Concept mistake

The offer does not meet its market

This is the most expensive mistake, because it cannot be corrected without redoing most of what has already been paid for.

  • What it costs: the fit-out and the equipment committed to a format that does not hold, the opening stock, and the months of trading spent looking for customers who never come.
  • How to spot it beforehand: have real customers pay before the opening, in a light format. A market stall, a corner, a few private events, an online pre-order.
  • What does not spot it: feedback from friends and family, stated-intention surveys, and the number of people who find the idea likeable.
Warning signal Nobody outside your close circle has yet paid for what you are about to sell.

Premises mistake

The site does not match the model

A lease is signed in a day and carried for years, rent included, even when the business stops trading.

  • What it costs: a rent sized for revenue the location cannot deliver, unplanned works on a badly assessed building, and a margin eaten before you even open.
  • How to spot it beforehand: start from the model, not from the site you fell for. Count footfall at several moments of the week, check that the use is authorised and have the works costed before you sign.
  • What does not spot it: the beauty of the place, the promise of a neighbourhood about to change, and the urgency created by another applicant.
Warning signal You are viewing premises before you have written down what you need to take each day to carry them.

Hiring mistake

The team arrives too late or in the wrong role

It does not show in the funding plan, but it shows from the first service, and customers remember it.

  • What it costs: opening weeks below the expected standard, negative reviews at the moment they weigh the most, quick departures and hiring to do all over again while trading.
  • How to spot it beforehand: set the key roles at the same time as the opening date, and plan a real training period, menus and processes in hand, before the first customers.
  • What does not spot it: the idea that hiring will be easy when the time comes, and the bet on training on the job during the first weeks.
Warning signal The opening date has been announced and no hiring has started.

I have opened, and I have closed.

With GreenPizz, an organic pizzeria, I opened three restaurants in Paris and one in Canada under a knowhow licence between 2010 and 2016. I have lived through successful openings and shutdowns, leases that carry a business and leases that smother it, teams that hold an opening and teams that arrive too late. That experience from both sides is what makes the advice useful: I do not only tell you what works, I also know what it looks like when it does not.

03 / Engagement

How I work on a launch.

Four phases, in order. Each one ends with a decision taken and a document you can defend on your own, not with a recommendation to think over.

01

Validate or correct the concept

We go back over the offer, the target and the promise, then we look for proof that someone will pay. Depending on the project, that means studying the catchment area and the direct competition, and running a full-scale test in a reduced format. At the end of this phase, either the concept is confirmed, or it is adjusted while adjusting it is still free.

02

Build the model and the business plan

Prices, cost of goods, payroll, the rent you can carry, upfront investment, break-even point and cash month by month. We build the assumptions together and you keep control of the file, because it will have to be defended to a bank or a partner. The model also works as a filter for what follows: it says what you can sign.

03

Prepare the opening

Searching for and choosing the site, reading the lease before signature, the works schedule, selecting suppliers and purchase terms, the day one org chart, hiring the key roles and training before opening. This is the longest and the most concrete phase, the one where decisions come one after another and where a fast outside opinion saves weeks.

04

Launch commercially and hold the first weeks

Local and online visibility built before the opening, the business listing, reviews, first customers identified. Then the tuning: real average spend, real cost of goods, flow by time slot, team rotas. The first weeks say what the plan had not anticipated, and that is when you correct while it is still easy.

04 / Who for

The cases I take on.

Three situations, one thing in common: the project has moved from idea to execution, and the decisions commit money.

New business

Founders before the opening

You are opening your first shop or your first restaurant, and you are alone in making the calls.

  • A concept to confirm or to tighten
  • A model and a business plan to build and to defend
  • Premises, suppliers and team to secure in the right order
When to contact me Before signing anything: the lease, a franchise agreement, an equipment order or a loan.

Diversification

Groups launching a new business line

The company already runs, but the new activity cannot be managed like the old one.

  • A new format, a new area or a new channel to frame
  • A model to isolate from the rest of the business in order to judge it honestly
  • A project team to build without unbalancing current operations
When to contact me At the moment the decision to launch is taken but nobody inside has the time to carry it.

Replication

Concepts to replicate

A first outlet works and you want to reproduce it, owned, franchised or under a knowhow licence.

  • What makes the first site succeed, to be identified and then written down
  • Processes, training and quality control to formalise so they can be transferred
  • The economics of the copy and of the network to check before recruiting partners
When to contact me Before signing the second site or the first franchise agreement, while the model can still be changed.

05 / Experience

What I have opened.

Openings done, not observed. Restaurants, leisure and e-commerce, in France and in Portugal.

  • 15 yearsbuilding, launching and running companies
  • 6companies founded or co-founded
  • 4restaurants opened: 3 in Paris, 1 in Canada under licence
  • 1 500 m²of venue operated in Lisbon

GreenPizz, an organic pizzeria, from 2010 to 2016: three restaurants opened in Paris, in the 9th, 13th and 15th arrondissements, and one in Canada under a knowhow licence. The Wave Factory, from 2017 to 2020: an indoor urban surf venue in Lisbon, with a 100 seat bar and restaurant and a 40 seat coworking space. VeryGourmand, from 2021 to 2024: an e-commerce business selling French regional produce delivered across Europe.

Three different models, the same workstreams every time: a concept to prove, a margin to hold, a site or a platform to make work, a team to train and first customers to go and find. That is what I bring to the projects I support today.

06 / Questions

Questions.

The six questions that come up when a founder calls for the first time.

When should I get in touch?

As early as possible, and ideally before the lease is signed and before the first heavy financial commitment.

The earlier the work starts, the less the corrections cost. A concept can be reworked in a week while it is still on paper. Once the site is signed, the works have started and the equipment is ordered, the same correction is paid for in months and in cash. If you have already signed, nothing is lost, but the room for choices narrows and the work bears more on running the business than on the project.

How long does launch support last?

As long as the project, from concept validation to the first weeks of trading, with an intensity that varies a great deal from one phase to the next.

Framing the project and preparing the opening demand a sustained pace, the works period far less, and the opening itself close presence again. The format follows that rhythm rather than a single package: consulting days spread over the period, with fixed checkpoints at the moments when decisions are made.

Do you write the business plan or help me write it?

I build the model with you and you keep control of the numbers, because you are the one who will have to defend them to a bank, a landlord or a partner.

A restaurant business plan written by someone else is spotted in three questions, and the funder always asks them. So I work on the structure of the model, the price and margin assumptions, the break-even point and the cash of the first months, then I have you hold your own numbers until you can explain them line by line without the file in front of you.

Do you work with founders who have no capital of their own?

Yes for the thinking and the framing, but with no capital and no identified funding, a physical retail project does not get past the premises stage.

In that case, the useful work usually consists of shrinking the starting format, testing the concept in a lighter form such as a corner, an event, a market stall or an online shop, and building proof of market before going back to a funder. The path is longer, but it exists and it produces a far stronger case.

Do you stay involved after the opening?

Yes, and that is often where the work counts most, because the first weeks reveal what the plan had not anticipated.

The gaps show up quickly on average spend, real cost of goods, customer flow by time slot and team rotas. This tuning phase sometimes continues as fractional operations leadership, when the need goes beyond the launch and bears on how the company is organised.

Can you support an opening in Portugal?

Yes: I founded and ran a company in Lisbon and I still work there, so the Portuguese market is not theoretical ground for me.

The differences that matter are concrete: how leases and works are handled, administrative lead times, pressure on hiring, tourist seasonality and the weight of local word of mouth. On Portuguese legal, tax and accounting matters, I work with local specialists rather than standing in for them.

07 / Recommendation

What the people who worked with me say.

Armel is a great professional, and I have had the pleasure of working with him many times. Excellent at challenging ideas and highly effective when it comes to implementation, he has always been a valuable asset when launching new products and services.
