Scale up! With customer help!
Pitchup is a great idea, it needs to be bigger though! It needs to be the Booking.com or airbnb of camping.
Suggest you mobilise Pitchup customers to help you scale.
Provide a money off voucher to customers for every campsite they recruit onto Pitchup.
Put together a new section that has a campsite recruitment form in a range of languages that campers can give/send to campsites.
By giving cash back you can encourage people to do a campsite recruitment drive to make their next holiday cheaper.
Replicate the airbnb/uber ratings model, so no-showers are marked down. Giving PitchUp a real benefit for site owners by providing confidence that your customers show up.
