How It Works

Define your audience segments, choose fundraising channels (telephone, giving day, email, direct mail), and describe your case for support.
Run simulations
We run 500 Monte Carlo iterations using sector benchmarks, network effects, and capacity models to forecast realistic outcomes.

Fundraising Channels We Model
The simulator is built on real-world data from Hubbub's fundraising campaigns. Learn more about each channel.
Telephone Appeals
The most personal fundraising channel. Telephone campaigns engage and inspire donors through the power of conversation — driving single gifts, regular giving sign-ups, legacies, and more.
Typically the strongest channel for converting regular givers, with ~35% of activated donors signing up for recurring gifts.
Giving Days
A 24–48 hour online giving campaign that engages your entire community. Social ambassadors, challenges, and match funding create urgency and peer-to-peer momentum.
Network effects are strongest here — giving days tap into social proof and community connections to drive participation.
Causes
More than an online donation form. Hubbub Causes puts the donor at the centre of their giving experience, growing community and fostering a lasting culture of giving.
Ideal for email and direct mail campaigns. Personalised giving pages and segmented outreach maximise engagement and response rates.
