Three is enough to give a client a real comparison without asking too many developers to put in unpaid time on the same brief. It keeps the challenge fair to developers while still giving clients a meaningful choice.

Nothing bad — you keep your profile, your stats update to reflect participation, and your submission for that project is deleted per our retention policy unless you’ve agreed otherwise. You’re free to accept the next invitation that comes your way.

No. Show2Build is free to join for both clients and developers. There are no subscriptions, no listing fees, and no charge for taking part in a challenge.

Once a client chooses a winning developer, both sides agree a project scope, price, and a schedule of project phases on-platform. The client pays a deposit to start, then pays per phase as work is delivered. Show2Build takes a transparent platform fee out of the developer’s earnings only when a payment is made — never before.

Either the client or the developer can raise a dispute through the platform if something goes wrong mid-project. It’s reviewed based on the project agreement and evidence provided, and resolved with a clear outcome — a refund, a release of funds, a split, or no action.

Yes. Clients specify the technologies relevant to their brief, and developers who match that stack are the ones invited. You always know the expected stack before you accept a challenge invitation.

No. Unless you explicitly agree otherwise, a losing submission is deleted rather than kept or reused by the client. See our challenge rules for the full policy.

Only a small, representative slice — enough to demonstrate real ability, not the whole thing. Briefs are meant to be scoped so they’re realistically buildable within 24 hours.

All communication happens on-platform once you’re invited, so you can ask clarifying questions about the brief before committing your 24 hours.
