Bottom line
Pick Gust if the groups and accelerators you want already take applications on gust.com, or if you need Delaware C-Corp formation through Gust Launch. Pick Onefive if the next job is a permissioned dataroom, a startup profile, and intros inside a European network.
These are complementary products. Gust is an application network plus company-as-a-service. Onefive is a diligence workspace. Gust does not replace a GDPR dataroom in French. Onefive does not replace an application into a US angel federation that already lives on Gust.

Where each one wins
Onefive
- A permissioned dataroom on day one, with watermarks and view tracking.
- French and English in the same product, built for a European raise.
- A network you join, not an application queue into someone else's list.
Gust
- The application layer many US angel groups and accelerators already use.
- Gust Launch: Delaware C-Corp from $450 per year, then SAFEs, notes, and a 409A.
- Generally available today, with a weekly activity summary on applications.
Who should pick which
If the angel groups on your shortlist already run on Gust, open Gust first. Build the company profile. Apply. Do not expect a personal Kanban of 200 names you sourced yourself.
If the next meeting is diligence in Paris, Berlin, or London, and the files still live in Drive, start with Onefive. Keep Gust if a specific group still requires a Gust application.
A French SAS raising a European pre-seed rarely needs Gust Launch as the first buy. A US founder applying to 12 angel federations on Gust rarely needs Onefive as the first login. Some teams will use both: Gust for the application, Onefive for the room.
Frequently asked questions
Is Onefive a Gust alternative?+
For a European dataroom, bilingual product, and founder-investor network, yes. For applying to angel groups that already sit on Gust, or for Delaware incorporation, no.
Is Gust an AngelList alternative for pre-seed outreach?+
Partly. Gust is closer to an application network than to AngelList's SPV and syndicate stack. If the job is investor outreach you control, Foundersuite or OpenVC is the closer CRM. If the groups you want already live on Gust, stay on Gust.
Does Gust include a data room?+
Gust gives investors a company profile and document downloads on applications. That is not a founder-controlled virtual data room with per-group permissions and watermarked view-only PDFs. Onefive treats the room as the default surface.
Which is free?+
Onefive is free on the waitlist during pre-launch. Gust lets you start a profile and apply; Gust Launch incorporation starts at $450 per year on their public pricing page.
Raising in Europe, not applying to a US angel group?
Join the Onefive waitlist for a dataroom and a European network. Keep Gust if the groups you want already sit there.
