I was using Airtasker to grow my business, and did exactly that. Do an odd job, and do future work outside of the app. Pretty easy to justify this when you can remove Airtasker fees and they pay less the next time around. But in saying that, there are enough odd jobs for the app to continue growing, and not many people save a tradie's number for future use from what i've seen, they like to shop around (except older generation from my experience). The app will have plenty of new users and repeat users for differing odd jobs. It is an ecosystem of its own. I am not worried about stickiness.
