DemandOS — Don't Discount and Hope. Know Who's Ready to Buy.

Inspiration

We've all experienced it: finding something we love, adding it to our cart, and leaving because it's just a little too expensive.

For shoppers, there's no easy way to say, "I'd buy this right now for $140 instead of $180."

For brands, the problem is even bigger. They have no clear way of knowing how many lost customers would actually purchase at a different price. Their traditional option is to launch a public sale, discounting products for everyone — including customers who might have paid full price.

What if brands could know who was ready to buy before deciding to discount?

What It Does

DemandOS introduces a new way for consumers and merchants to agree on a price.

For shoppers: Name your price directly on an online store. Set the maximum you're willing to pay, authorize a conditional purchase, and let DemandOS complete the order automatically if the brand accepts.

For merchants: See how many eligible shoppers are ready to purchase at different price points. Instead of launching a storewide sale, release a limited number of private offers and match those shoppers to available inventory.

One price from the buyer. One decision from the merchant. One completed transaction.

How It Works

Imagine a premium leather bag priced at $180.

A customer loves it, but would only buy it for $140.

Instead of abandoning the purchase, they click Set My Price and authorize a conditional purchase at $140.

On the merchant side, DemandOS reveals 24 eligible purchase requests at that price.

The brand can release 12 units privately without changing its public $180 price.

DemandOS then checks the purchase conditions, matches eligible shoppers, and processes supported sandbox transactions.

The result is a new opportunity to convert previously unfulfilled purchase intent into completed orders.

How We Built It

DemandOS combines three core systems:

1. Consumer Price Lock

A lightweight purchasing experience embedded into an existing storefront. Customers select their maximum price and define the conditions under which they authorize a purchase.

2. Merchant Decision Engine

Merchants see aggregated buyer demand and evaluate whether a limited private offer makes economic sense.

The decision model considers inventory, selling costs, price limits, expected full-price sales, and potential cannibalization.

3. Matching and Transaction Engine

When a merchant releases an offer, DemandOS checks customer eligibility, inventory availability, and payment authorization before executing the supported checkout flow.

The goal is to turn real purchase intent into transactions, rather than simply generating price alerts.

Market Intelligence and AI

DemandOS also incorporates market intelligence to support merchant pricing decisions.

Apify can collect public market signals, including competitor pricing and seasonal product trends.

A pricing agent can analyze these signals alongside actual buyer requests and inventory to propose a price and release quantity.

Merchant-defined rules and deterministic checks validate recommendations before any offer is executed.

The core insight: Instead of using AI only to predict demand, we use buyer-provided purchasing conditions to make demand actionable.

Challenges We Faced

The biggest challenge was finding the balance between simplicity for consumers and profitability for merchants.

Simply letting consumers bid on products wasn't enough. Brands need a compelling reason to accept a lower price rather than continue selling at full retail.

We therefore focused on three challenges:

  • Protecting full-price sales: Private offers should target incremental opportunities rather than automatically discount all demand.
  • Making intent actionable: A wishlist or abandoned cart isn't a confirmed purchase. We distinguish interest, conditional authorization, and completed transactions.
  • Removing friction: The consumer should only need to name a price, while the merchant should only need to approve an economically justified release.

What We're Proud Of

We transformed a traditionally one-sided pricing model into a two-sided buying experience.

Instead of brands announcing prices and hoping shoppers purchase, consumers can express their purchasing conditions first.

Merchants gain visibility into that demand and can decide when fulfilling it creates value.

We designed DemandOS to work inside existing online storefronts rather than requiring shoppers to join another marketplace.

What's Next

We want to make DemandOS an embeddable commerce product for online retailers.

Next steps include:

  • Integrating with production e-commerce platforms.
  • Expanding supported payment authorization and automated checkout.
  • Testing real conversion lift and full-price cannibalization with merchants.
  • Improving merchant pricing recommendations with real transaction data.
  • Developing a transaction-based business model aligned with completed sales.

Our vision: A world where customers don't have to wait for sales, and merchants don't have to discount blindly.

Don't discount and hope. Know who's ready to buy — and make the sale.

Update: Visa Integration Is Now Working!

Our Visa integration wasn't working properly during judging this morning, but it's now up and running! We wanted to share a bit more about how it fits into our vision for reimagining shopping.

We integrated Visa's Merchant Offers Resource Center (VMORC) sandbox to explore how existing merchant offers can connect with DemandOS's buyer-driven pricing model.

What makes this exciting for Visa's Reimagining Shopping challenge is that we're not trying to create another standalone shopping marketplace. We're building a layer that could work within Visa's existing cardholder, banking rewards, and merchant ecosystem.

Instead of merchants deciding on discounts and hoping customers buy, DemandOS flips that process: shoppers tell merchants what they're willing to pay, and merchants decide which offers make business sense.

This creates value across the ecosystem:

  1. For shoppers: More personalized shopping experiences and greater control over prices.
  2. For merchants: More opportunities to convert missed demand into profitable sales without offering blanket discounts.
  3. For Visa: A new way to engage existing cardholders and merchants, potentially increasing purchase conversion and payment volume without needing to acquire an entirely new customer base.

We're reimagining shopping from retailer-driven discounts to consumer-driven demand, powered by the reach of Visa's existing ecosystem.

Engineering Update — What Makes DemandOS Work

1. Real Purchase Intent, Not Predictions

Instead of guessing demand from browsing behavior, we capture buyer-defined price limits and conditional purchase commitments. Merchants can see exactly how many customers are eligible at each price.

2. Profit-Aware Matching Engine

Our engine evaluates inventory by color, payment fees, minimum margins, and potential full-price cannibalization. A $180 bag with 24 eligible buyers at $140 can become a 12-unit private release worth $1,680 in potential revenue.

3. AI Recommendations With Deterministic Guardrails

AI agents propose pricing and release quantities, but every recommendation is independently validated against actual inventory, buyer authorization, and profitability constraints. No black-box pricing decisions.

4. Human-in-the-Loop Commerce

The merchant makes the final decision. Only approved offers move into matching and the supported transaction flow, without changing public retail prices.

The key idea: we're not building another AI shopping assistant. We're building a new way for buyers and merchants to agree on a price and actually make the sale.

Figures reflect our seeded demo scenario.
