02 / BUSINESS MODEL

How does it charge?

one-time

Bought per item; specific prices not found; members (Sponge Club) get free standard delivery

The above describes historical pricing. Check official website for current prices.

03 / ACQUISITION

Where do users come from?

Paid traffic is 77.1% (mainly bought), organic search 12.6%, with purchase-intent keywords such as "birthday cake", "letterbox cakes uk", "send cake in post" and "red velvet cake gluten free"; brand keywords are only 12.8%. Direct visits 10.3%. New users are classified as Other; returning users come through direct visits and membership repeat purchases.

Channel share, initial acquisition, and growth drivers are distinct; correlation does not imply proven causation.

04 / YOUR NEXT QUESTION

What remains to be verified?

The following are research questions, not established market opportunities.

  • What do target users actually pay for? Is there direct user feedback or paid interview evidence?
  • Are these historical prices still active today? What are the conversion, retention, and fulfillment costs?
  • Is the "Other" channel still viable? What resources do indie devs need to test it?
  • Whose needs are competitors failing to meet? Find specific evidence before deciding on your angle.
