Enough intro, let’s map!

Org map

It is hard to define an anchor

Our organisation works as a (partial) multi-sided marketplace

We have different segmentation of attendee users:

  • Beginner (student)
  • Advanced (professional)
  • Job seeker (networker)

�We have other types of users:

  • Speaker (expert)
  • Company (sponsor)

Events are the lifeblood of the organisation

If we broke down per user type…

  • 👍 We’d have a terribly complex map
  • 👎 We’d see what each type of user gets of value

20 of 45

We’d also get a conflict:

Is Speaker a user or a component?

Being volunteer-driven means we may sometimes lack enough hands

What is preventing us from having more events?

27 of 45

28 of 45

High value flow for events:

  • Speaker
  • Venue

High inertia for events:

  • Speaker
  • Companies

How does organising just a meetup map?

Seen from the point of view of a meetup…

You need for sure a speaker and a venue

34 of 45

35 of 45

You need a stream of proposals and a company to provide a venue

36 of 45

Of course having attendees is great

  • We can assume that if we provide an event, attendees will come (big assumption!)

​

  • Our limiting factors are then
    • Companies (because of venues)
    • Proposals (because of speakers)

38 of 45

We knew…

Speakers and sponsors were important

We didn’t know they were so fundamental to drive events

39 of 45

What other actions�do you see?

How can we map the multi-sided market?

How do we determine the value of each type of user?
