Kleinigkeiten:

- your url-structure is confusing (www.timeup.io vs start and landing)

- write "use timeup.io now" instead of "try"; add try once money is involved

- add small titles to the 4 bullets-list on event entry; right now they are very confusing; there is also too much white-space on desktop browsers; perhaps left-align the event-entry form on larger screens

- Slot Length should have an effect on Timeframe so one can start at 8:30 for example

- Text liest sich oftmals zu Deutsch (zBsp: "timeup.io focuses on the finding of the best fitting...") oder ist Englisch inkorrekt (zBsp: "Shoot a message!" müsste "Shoot us a message!" sein)
