Bottom line
Pick Foundersuite if you want a Kanban pipeline against a very large investor database and you are ready to run outreach volume. Pick Onefive if the next bottleneck is the dataroom, GDPR, or finding a warm path in Europe.
Foundersuite's virtual data room is a paid add-on. Onefive treats the room as the default surface. That single difference decides most pre-seed buys.

Where each one wins
Onefive
- Dataroom included, with permissions and view tracking.
- Built for a European raise: Paris, GDPR, French UI.
- Profiles and matching instead of a purchased-looking list.
Foundersuite
- A pipeline CRM you can sit in all day.
- A very large investor directory if you believe the vendor count.
- Generally available, with a free Basic tier to start.
Who should pick which
If your raise plan is “build a 300-name list and work it,” Foundersuite is the familiar tool. Watch the data-room add-on the first time a partner asks for a structured folder.
If your raise plan is twenty named funds, three warm intros, and a room that does not leak the cap table, Onefive is the closer match.
You can export a Foundersuite list and still run diligence in Onefive. Do not pay for two full CRMs unless both jobs are real.
Frequently asked questions
Is Foundersuite or Onefive better for pre-seed?+
Foundersuite if outreach volume is the constraint. Onefive if diligence, language, or European intros are the constraint.
Does Foundersuite include a data room?+
Yes, as a paid add-on on every plan, per Foundersuite's public pricing. It is not the default free surface.
Does Onefive have an investor database like Foundersuite?+
No. Onefive is a curated European network with matching, not a 200,000-row directory. If the directory is the product you want, stay on Foundersuite or OpenVC.
Need the room more than the mail merge?
Join the Onefive waitlist. Keep Foundersuite if the list is still the job.
