Interested in starting your own entrepreneurial journey in marketing services but unsure what to expect? Then read up on our interview with Antoine Heftler, Founder of Leadnostic, located in Paris, France.

What's your business, and who are your customers?

We work with Private Equity & VC firms to accelerate the marketing-powered growth of their portfolio companies. We usually spend 6 to 9 months (re)structuring marketing & lead generation in a very operational angle. Once we're done, the new team can scale, optimise, and deliver increasing ARR to the company!

Tell us about yourself

I built Leadnostic on 20 years of expertise in using marketing as a scaling accelerator & revenue generation for SaaS scale-up & global IT companies:

  • From founding an early-stage startup to running worldwide IT leaders' transformation.
  • As Head of Operations & CMO.
  • As a digital transformation consultant via VCs & PEs in Sweden and the UK.
  • Across Europe (France, UK, Sweden, Finland, Romania) & Asia (India for five years).

I am also certified as a marketing Blockchain specialist by INSEAD.

What's your biggest accomplishment as a business owner?

Each good review and recommendation from one investor to another is a fantastic accomplishment for me!

What's one of the hardest things that comes with being a business owner?

Finding a business partner! Contact me if you're interested!

What are the top tips you'd give to anyone looking to start, run and grow a business today?

  1. Specialise yourself in a topic and start digging around it.
  2. If you don't have too many strings attached, go work in the farther country possible from yours!
  3. If Mondays don't usually feel good, it's time to change :-)

Where can people find you and your business?
