Take stock ;
build what's next.

I'm Vincent Mattart, serial entrepreneur. I co-founded Funere, Leez and BePaid, and I still build them myself. It all starts with a 30-minute conversation, to see whether I can help. If I can, we begin with a consulting session, which then leads to Scale or to full support through the startup studio.

eFoundr in 40 seconds

On a split-flap board, "Your next step" cycles through AI at work, automation, mobile app, internal tool and client portal, then through the full stop, the comma and the semicolon. eFoundr; consulting, Scale and startup studio in Switzerland. I'm Vincent Mattart. I co-founded Funere, Leez and BePaid, and I still build them myself. First line, "I run a company": a first call, then consulting, 4 or 8 hours to take stock, with Vincent and Alessandro, up to the decision. Then Scale, building what came out of consulting: a first prototype within 5 working days, usually, the build over 2 to 8 weeks, then the launch. Second line, "I'm starting a startup": conversations, shareholders' agreement, kick-off, then for the long run. A tech partner for your startup: CTO or CPO, for an equity stake. It all starts with a 30-minute call, free and with no commitment. Take stock; build what's next. efoundr.ch

Consulting first.

It all starts with consulting. If something worth building comes out of it, Scale takes over. The Studio is the startups I commit to myself.

How we move forward.

The path is not the same for a company and for a startup. Pick yours, then scroll through the steps.

For an SME or an established company. We start small, and only build what is worth it.

  1. First call

    30 minutes · with Vincent or Alessandro

    You send me a few lines about your situation, then we talk for 30 minutes. I tell you honestly whether I can help, and how.

    What you get

    • A clear answer: we go on, or we stop there
    • If we go on, a date for the consulting session
  2. Consulting

    4 or 8 hours · with Vincent and AlessandroConsulting

    Half a day or a full day at your place, on your numbers, your tools and your daily work. We listen, ask the awkward questions, and spot what is stuck and what could pay off.

    What you get

    • The leads worth following, ranked
    • A frank opinion on what is worth building
    • The view of two people who run their own products
  3. Decision

    Together, at the end of consultingConsulting

    Together we look at whether there is something to build. Sometimes there isn't: you leave with the leads, and that is a useful answer too.

    What you get

    • A clear scope, or a clean stop
    • No project started out of habit
  4. Prototype

    Usually 5 working daysScale

    A first version you can touch, to check the direction before going further. Better to be wrong in 5 days than in 2 months.

    What you get

    • Something concrete to test with your team
    • The direction confirmed, or corrected, early
  5. Build

    2 to 8 weeksScale

    We build, in small deliveries that you test along the way, and adjust as we go.

    What you get

    • A tool that runs, on standard technologies
    • No black box: you see the work move forward
  6. Launch;

    End of ScaleScale

    The tool goes into production, documented and handed over to your team.

    What you get

    • The code, documentation and accounts belong to you
    • You are free to keep working with me, or without me

What I have built, and still run.

Bereavement, business succession, invoicing: fields with nothing in common, each with its own challenges. That is what keeps me creative, and what I then bring to your projects.

Portrait of Vincent Mattart

Vincent Mattart

Founder of eFoundr · Serial entrepreneur and CTO

In 2017, I co-founded Gold Avenue and ran its tech for seven years. Revenue grew from 0 to more than CHF 500 million, with a tech team of more than 25 people across Switzerland, France, Ukraine and India.

Before that, I built Pixeleez, my web agency: more than 250 web and mobile projects, then a sale in 2022. Today I co-found startups and run their tech.

My rule: get to market as fast as possible, because that is where the real problems are.
