onefive is the platform for the French startup ecosystem. It is deliberately multi-role: founders, investors, business angels, mentors and programs live in the same environment rather than in two products that talk past each other.
In practice an investor does not get a separate space. You get the same feed, the same directory and the same pages as founders, plus what is specific to your side: the datarooms opened to you, and the profiles you can verify before replying.
What you get today
Verified profiles
Founders, investors and mentors all carry a verified profile. You know who you are talking to before accepting a conversation.
Startup pages
A public page per company, with the founding team and the cap table when the company chooses to publish it.
Dataroom access granted by the founder
When a company opens its dataroom to you, you get a signed link that can expire. Documents are versioned, so you read the current version, not the one from three weeks ago.
The Spotlight directory
Incubators, accelerators, contests, campuses and events across the French ecosystem: useful context on where a company comes from and who backed it.
Le Tour de Table
The weekly digest of French tech funding, M&A, LBO and IPO deals. Every Friday, in five minutes.
Peer discussions
Founders talk to each other at the same stage. It is the best place to understand what is actually happening in a market before investing in it.
What onefive does not do
onefive does not invest and takes no share of the rounds raised on the platform. It is a product, not a fund.
There is no curated deal flow, no scoring, and no recommendation engine deciding which companies deserve your attention. You search, you filter, you decide.
And there is no online subscription flow: rounds are not signed on onefive.

Verify your profile
A verified profile changes how often founders reply. It is also what separates you from an anonymous account in a thread.

Frequently asked questions
Is onefive an investment fund?
No. onefive is a platform. It does not invest, does not co-invest, and takes no share of the rounds raised by the companies using it.
What does it cost an investor?
€0. The full product, no charge. There is no paid plan today.
Do I get a curated deal flow?
No, deliberately. There is no curation and no scoring: you see the ecosystem as it is and do your own filtering. What the platform gives you is identity verification and context, not an investment opinion.
How do I get access to a company's dataroom?
The founder opens it, investor by investor. You receive a signed link, possibly with an expiry; there is no public URL to a dataroom.
Is it France-only?
France is the first market and most of the listed companies and programs are French. The product and the content exist in both French and English.
