Our investment vehicles
The Only Planet Venture One
One of the startup investment vehicles we manage is The Only Planet Venture One. The technologies required for a more resilient economy already exist, but too many struggle to move from research and early validation to industrial adoption. Venture One was created to close that gap: investing early, working alongside founders and connecting innovation with the organisations able to test, adopt and scale it. Geography: Europe.

Rome Advanced District
Where technology meets industry.
Programme activities take place at the Rome Advanced District, the industrial innovation campus at the Gazometro in Rome.
Who can apply
- Hardware and software startups can apply.
- MVP and prototype-stage companies can apply.
- Startups do not necessarily need to be incorporated before applying; the startup must incorporate during the programme in order to receive the investment.
- Startups with an existing product and customers can still be relevant.
- The programme is intended for startups that have not already received VC funding.
What to submit
You do not need a full business plan. A general startup presentation covering the company, technology, market, team and key business metrics is sufficient.
Next steps
Applications are reviewed, shortlisted teams are assessed, and selected founders move into the investment and support process.
Commitment
The founders and team members necessary for the development of the startup are expected to work full-time on the company during the programme and attend in-person sessions at the ENI Joule headquarters at the Gazometro in Rome. Other founders, employees or supporting collaborators may work part-time and/or remotely.
