Least active person buys the coffee*
Buy us a coffee £2.50
Keep our caffeine levels topped up for a few hours. Enough coffees and we'll have a new product for you.
Buy us dinner: £10.00
Sustain us with dinner and we'll make beautiful code into the night.
Pay us to stop: £100
We accept you might not like us. This makes us sad, although our office cat, Ripley, doesn't seem that bothered. If you pay us enough we might just stop.
