Tech & growth partner · fractional CTO

Your tech & growth partner.

You have a product that sells. What you lack is the digital machine to sell more of it. I build it and I run it, in exchange for a share of the results.

Why a partner rather than a vendor
01

Same interest

A vendor gets paid when they deliver. A partner gets paid when you sell. I have no reason to sell you a website you don't need, and every reason to make the one you have work.

02

Tech, and the marketing that goes with it

Website, online store, automation, data, SEO, email, social, ads. I build the machine and I keep it running. When a project calls for a top-tier marketer, I bring one in and I lead: tech in the service of what sells.

03

An agency behind me

JR Agency produces, I lead. You have one point of contact, and the capacity of a team when things need to move fast.

What I bring, what I look for

I don't have a product. You do.

Tech5 / 5

Twenty-eight years on the web. Websites, stores, platforms, automation, AI. It's what I do best, and JR Agency is behind me.

Marketing & communication4 / 5

SEO, email, social, ads, sales funnels: I've been running them on my own projects for years. Enough to get most small businesses off the ground. If your market demands more, I bring a marketer into the project and I stay at the helm.

Product0 / 5 · that's you

I have nothing to sell. You have a coffee roastery, a school, a craft, customers who come back. That's exactly what I'm missing, and it's why this page exists.

A good product without a digital machine plateaus. A digital machine without a product is useless. We each hold half.

The two real cases

Two businesses where I'm not a vendor.

Café ROGO

Artisan coffee roaster, Beaujolais, France · caferogo.fr

Ludovic roasts, I handle everything that sells online: the new store launched in July 2026, SEO, social media, email, and the ideas that bring customers back.

L'espace du songe

Online art school, with Franck Tonnellier · espacedusonge.com

Franck teaches, I build: the platform, the sales funnel, the content, the analytics. Co-founded several years ago, still running.

Compensation: a share of the school's results.

In both cases, I didn't bill a website. I took a risk with them.

What I build on my own

When I don't have a partner, I build anyway.

What I'm looking for is a product worth that energy.

  • WebAndFreeCourses and a newsletter for web freelancers, with a home-built platform that replaces Mailchimp and the course tool.An audience, a funnel, a tool: the whole machine, solo, for years.
  • SeptaraA feel-good mobile app in three languages, in-app payments, published on Android. Not on iPhone: Apple rejected the listing in August 2026, category deemed saturated, appeal denied.Mobile end to end, down to the stores and monetization. And proof that you don't win every time: I say it, because it's part of the job.
  • Je vends la boutiqueA listings site for French businesses for sale, with online valuation and listing distribution. A niche real-estate market, and a different model: the platform, not the service.I can build a marketplace in a market I didn't know, and keep it alive.
How it works

A month to get to know each other, a written agreement, then we build.

  1. ApplicationTwelve questions, five minutes. You know right away whether your project passes the first filter.
  2. A discovery monthIf the project passes the criteria, we take a month to talk: your numbers, your tools, your market, and above all how each of us works. No commitment, no invoice. At the end, we both know whether we want to continue.
  3. The written agreementI propose a plan and a contract: starting fee, percentage, twelve-month commitment, exit terms. Nothing gets built before signing.
  4. We buildOne check-in a week, a numbers review every quarter. After the first year, the partnership continues in six-month periods, and either side can end it cleanly with three months' notice.
The criteria

I don't take everyone, and that's good for you.

I'm looking forI don't take
A product or service that already sellsAn idea without customers
A margin that leaves room for a percentageA product with a 5% margin
A founder who can keep up if sales doubleSomeone already at the limit of what they can produce
A founder available at least 1 to 2 hours a weekSomeone who wants to "delegate and forget about it"
A market where digital can change the gameHealthcare and regulated sectors
A willingness to share the gainsSomeone looking for a free CTO
The model

A reduced fee, then a percentage of the results.

The fee covers the setup. The percentage is my real compensation. Both are written into an agreement signed before we start, with a duration and an exit door.

The numbers depend on your margin and on what needs to be built: we talk about them during the discovery month, not before.

What I can say right now
  • I never work on percentage alone.
  • I commit for at least twelve months.
  • I never take more than three partnerships at once.
  • The website, the accounts and the content stay yours.

Who I am

Johann Roche

On the web since 1998. Founder of JR Agency, which mostly works white-label for other agencies: WordPress, WooCommerce, custom sites, and since 2025 AI pipelines on every project. French-Brazilian, I live in Brazil, in Ceará, and I work with France every day.

For twenty-five years I sold websites. What I like most is making a business work with someone who has a real product. This page exists to find the next ones.

Application

Does your project qualify?

Twelve questions, five minutes, three screens. Instant answer on the first filter, then I read everything myself.

This is the question I read most carefully.

Frequently asked questions
Why a discovery month before signing?

Because we're going to work together for at least a year. A 30-minute call isn't enough to know whether we get along, whether your numbers hold up and whether I really have something to bring. This month costs you nothing and commits you to nothing. Me neither.

Why a twelve-month commitment?

Because a growth machine takes time to produce: SEO, email, a new store deliver their results over six to twelve months. I take a reduced fee at the start, so I invest at a loss for the first months. Twelve months is the time it takes for the bet to have a chance of paying off, for you as much as for me.

What if it doesn't work?

After the first year, the agreement allows an exit every six months, with three months' notice. Each side keeps what it built: the website, the accounts and the content stay yours.

What if I stop while it's working?

That's planned for, and written into the agreement from day one. What I built keeps earning for you after I leave, so it keeps compensating me for a defined period, on a declining scale. If the stop happens during the first year, the reduced fee is topped up to the normal rate. It's not a penalty, it's what makes a reduced fee possible in the first place.

You live in Brazil, how does that work?

I live in Ceará and I've been working with France for years: my two current partners are in Beaujolais and online, my agency clients are in France. The time difference is three to five hours depending on the season, which leaves me your whole morning and early afternoon. I come back to France regularly. For a partnership, we meet on video every week and in person when I'm around.

Are you a developer or a marketer?

Both, with a tech lean. I build everything technical and I run day-to-day communication. When a project needs a sharp marketing specialist, I bring them into the partnership and I coordinate. You keep a single point of contact.

Do you take equity in the company?

Not by default. A percentage of additional revenue is simpler, clearer and reversible. Equity only if we decide it together later on.

Why a fee if you're a partner?

It covers the initial production costs. Without it, I could only work with people who have nothing, and those are the most fragile projects.

Do you also do regular client work?

Yes, through JR Agency. This page is only the partner entrance.

How many partnerships at once?

Three at most. Available seats are shown at the top of this page.
