How to get your first 100 customers for a paper-thin flexible rechargeable battery card
To win your first 100 customers for a paper-thin flexible rechargeable battery card, go where gadget, EDC and eco-tech early adopters already hunt for novel hardware instead of burning cash on ads. The highest-fit communities are EDC and wallet-gear subreddits (r/EDC, r/EverydayCarry, r/Wallets) and gadget-discovery spaces (r/gadgets, r/INEEEEDIT, Product Hunt), plus crowdfunding-backer and eco-tech audiences who reward thin, clever, sustainable tech. This product sells on the 'wait, a battery that's thin as a card?' reaction — a crisp demo plus a Kickstarter and the right niche threads can seed your first 100.

FAQ
Where do gadget, EDC and eco-tech fans gather online?
In EDC and slim-wallet subreddits like r/EDC, r/EverydayCarry and r/Wallets, in gadget-discovery spaces like r/gadgets, r/INEEEEDIT and Product Hunt, on crowdfunding platforms, and in TikTok/Reels 'cool tech finds' niches. Eco communities like r/ZeroWaste add a sustainability-minded audience.
What's the fastest way to get the first 100 customers for a paper battery card?
Lead with the 'thin as a card, bends like paper' demo. Run a Kickstarter or Indiegogo to fund the first batch and capture 100+ backers at once, launch on Product Hunt, post the demo into r/EDC, r/gadgets and gadget TikTok, and seed a few tech reviewers to drive credible early sales.
Do I need an ad budget?
No. Crowdfunding, Product Hunt and organic gadget/EDC communities a founder with zero audience can use for free do the heavy lifting. A surprising demo plus a launch and a few seeded reviews are enough to start.
How do I make a novel battery feel trustworthy to buy?
Show real demos (charging a phone, bending the card), be transparent about capacity, charge cycles and safety, and use crowdfunding updates plus seeded reviewer videos as social proof. For an unfamiliar tech, credible third-party demos and clear specs convert skeptics into backers.
