The concept of the company, which initially specialized in software as a service (SaaS), is to start startups by partnering with founders and providing them, at project launch, with the idea, seed money and strategic advice.

Hexa's business model is based on identifying and solving specific problems encountered by the studio's founders or startups, from which it launches each new project with an average investment of 800,000 euros.

In 2018, eFounders reaches a significant milestone with six of its startups raising a total of 100 million euros and proceeds with the sale of its first company, TextMaster.

By the end of 2022, Hexa manages a portfolio of forty startups with a collective valuation of five billion dollars, having created around 2,800 for jobs and raised 700 million euros.

[9] In 2022, eFounders ratified its reorganization into several studios, renamed "verticals", and changed its name to Hexa, in reference to the hexadecimal system, which is understandable by both humans and machines.

[14] The aim is then to trigger a new phase of growth, with support over twelve to eighteen months, during which the startup's founders can sell part of their shares and a new CEO be appointed.

[16] The organization of this vertical differs from the previous ones: a physician is recruited to become its full-time medical director, while each startup is launched equally by an experienced doctor and a future CEO.

[17] This investment is particularly used to recruit two founders, a CEO and a CTO, and to set up a team of ten to fifteen employees to build the first version of the product, generally a software as a service.

[17] Hexa records around one exit per year, as was the case with the buyout of Briq by the unicorn Swile or that of Mailjet by its American competitor Mailgun, for sums reaching several tens of millions of euros.

[1] The startup studio has a 6% failure rate, with projects such as Bonjour, a platform to boost sales performance, and Station, a web browser for businesses, having ceased.

[1] Most of these are affiliated with the historic eFounders vertical, as is the case, for example, with Folk, a contact management application,[19] or Tengo, which aims to democratize access to invitations to tender from government procurements.

[20] The first startups in the other verticals were recently launched, like Numeral, which facilitates the automation of bank transfers and direct debits for companies[21] or Cohort, focused on user account management, linked to Web3.
