Retailers & API Partners
LastList connects with retailers through safe, compliant, product-only integrations, helping shoppers plan smarter trips across stores and marketplaces.
LastList is built by Boston304 LLC doing business as Braatz Innovations. It helps users organize shopping lists, task lists, wishlists, packing lists, and more, with intelligent product matching and real-time availability for shopping plans.
Privacy-focused, your personal information is never sold or shared. Lists stay on the user's device by default.

- No scraping: only official APIs and authorized data sources
- No automated checkout: users complete purchases on retailer sites

Partner With Us
We're actively seeking partnerships with retailers who want to reach engaged shoppers planning their purchases. LastList users are high-intent, they're actively organizing lists and comparing options before they buy.
What We Offer Partners
- Clean integration: We use official APIs only, no scraping
- Proper attribution: Affiliate tracking and conversion measurement
- Quality traffic: Users with clear purchase intent
- Fair representation: Your products shown accurately with real pricing
- Privacy compliance: User personal information is never sold or shared with partners
What We Need From Partners
- Product search API access (search by keyword, UPC, or category)
- Pricing and availability data
- Store location/inventory data (where available)
- Affiliate program enrollment, entirely optional. We integrate retailers that have no affiliate program and ask for no revenue share.
How We Make Money
Worth stating plainly, since we are asking retailers for data access rather than offering payment. LastList earns affiliate commission on some retailer handoff links, and delivery attribution through Instacart. A small number of specialty merchants are integrated through CJ Affiliate.
We do not sell user data. Retailer visibility is not for sale, and no retailer pays to rank higher in a shopping plan. We are not asking new retail partners for revenue share, and a retailer with no affiliate program is integrated on exactly the same terms as one that has it.
