01CPSC certificate completion assistantLaw and GovernmentBuild a compliance workspace for FBA and import sellers. Users import a product list, get category-based prompts for missing certificate fields, upload test reports and supplier documents, generate a submission checklist, and mark gaps for each product. The workspace brings together information scattered across spreadsheets, email, and supplier files. It focuses on organizing documents and flagging gaps rather than replacing existing submission, legal, or customs processes.View detailsHide details
Helps cross-border sellers organize the certificate data required for CPSC eFiling.

- Who it is for
- Cross-border sellers of children’s products, home goods, or consumer products on Amazon FBA who lack dedicated compliance staff.
- Smallest useful version
- Start with a web form and CSV import for products, importers, lab reports, and certificate fields. Let users check each item off. Exclude automated customs declarations, lawyer review, and a full-category rules library. Cover only document organization and gap prompts for common products.
- Why now
- CPSC reminded sellers in June that eFiling would become mandatory on July 8, and FBA and cross-border sellers began filling in certificate data. As the enforcement date approaches, small sellers need a low-barrier checklist tool more.
- Strongest counterargument
- The strongest case against this is that compliance carries significant responsibility. Sellers may prefer the backing of a customs broker, testing organization, or lawyer rather than trusting a new tool’s gap prompts.

02EU landed-cost calculatorBusiness and FinanceBuild a landed-cost and responsibility guidance tool for small cross-border sellers: they enter the product category, shipping origin, destination country, sale price, and shipping cost, then get a buyer-facing landed-price explanation, store announcement copy, and order-processing notes. The focus is not to replace customs systems. It is to help sellers quickly update product pages and customer-service messaging.View detailsHide details
Helps Etsy and Shopify sellers recalculate the landed price of EU orders.
Build a landed-cost and responsibility guidance tool for small cross-border sellers: they enter the product category, shipping origin, destination country, sale price, and shipping cost, then get a buyer-facing landed-price explanation, store announcement copy, and order-processing notes. The focus is not to replace customs systems. It is to help sellers quickly update product pages and customer-service messaging.
- Who it is for
- Small businesses shipping to the EU through Etsy, Shopify, or their own websites that usually calculate shipping and taxes in manual spreadsheets.
- Smallest useful version
- Start with a web calculator: select the destination country and product category to get a landed-price breakdown, product-page prompts, and customer-service replies. Leave out platform-based automatic repricing, fully automated customs declarations, and complex enterprise workflows.
- Why now
- Online sources indicate that the EU will remove the €150 duty-free threshold on July 1, requiring platform sellers to recalculate landed prices and customs responsibilities. This will directly affect product-page pricing and after-sales explanations.
- Strongest counterargument
- The strongest case against this is that logistics providers and platform checkout products may absorb the tariff rules. If an independent tool cannot connect to order flows, sellers may use it only briefly during the policy change.

03Steam e-ink template libraryGamesBuild a desktop companion app and template library that lets users display their Steam online status, current game, wishlist, controller battery level, weather, and calendar on an e-ink screen. The first version would not sell hardware. It would provide a setup wizard for existing screens, theme previews, a sync program, and community submissions.View detailsHide details
Helps players and desk-setup enthusiasts create and sync e-ink themes.
Build a desktop companion app and template library that lets users display their Steam online status, current game, wishlist, controller battery level, weather, and calendar on an e-ink screen. The first version would not sell hardware. It would provide a setup wizard for existing screens, theme previews, a sync program, and community submissions.
- Who it is for
- Players who already own a Steam Deck, mini PC, or desk-setup equipment and enjoy tinkering with peripherals but do not want to write code.
- Smallest useful version
- Start with a single-page app and a local sync utility: users sign in to Steam, choose a template, and generate a screen layout image. Drop the hardware compatibility matrix, community store, and complex animations. Support only manual refreshes and a small set of common sizes.
- Why now
- Valve open-sourced Steam Machine e-ink screen-related content, and the story reached No. 1 on the HN homepage that day, with high discussion activity. This may indicate that players are willing to experiment with more personalized, low-power desktop displays.
- Strongest counterargument
- The strongest case against this is that the installed base of hardware and the size of the tinkering-user segment are both unvalidated. HN activity may reflect discussion of open-source news rather than willingness to pay for templates and sync software.
