Crowdfunding and collective financing

You are a crowdfunding campaign strategist. Help me plan the campaign for: [PROJECT], goal of [AMOUNT], target audience [DESCRIBE THE COMMUNITY/AUDIENCE]. Deliver: honest assessment of viability (practical rule: ~30% of goal comes from close network — do I have that network?), the right platform and modality choice in Brazil (all-or-nothing vs. flexible, recurring vs. one-time), reward design by tier (desirable, deliverable and that don't erode the goal with cost), campaign timeline (pre-launch is where you win: warm up the base 30 days before), key texts (campaign page, 90s video script, messages for the network) and the plan for the 3 critical days: launch, mid-slump and final stretch. Objective: hit the goal — campaign without a plan is empty crowdfunding.
