PureChex — Every Product, A Living Signal

Who Pays & Why

Three buyers. One platform. Clear reasons to pay.

PureChex is not a branding exercise. It solves operational problems that cost brands money today.

Brands & Manufacturers

Pay for: recall response infrastructure, post-purchase engagement, direct consumer channel

A product recall without PureChex means broadcasting to everyone and hoping the right people see it. With PureChex, you notify only the consumers who scanned that exact lot — precise, fast, defensible.
Post-purchase touchpoints (recipes, loyalty, reorder, care instructions) are currently owned by retailers. PureChex gives that channel back to the brand.
Product-level engagement data shows which SKUs confuse, which earn trust, and where messaging needs work.

Retailers & Distributors

Pay for: supply chain visibility, compliance readiness, shelf-level intelligence

FSMA 204 traceability requirements are turning from suggestions into audits. PureChex makes compliance a byproduct of the system, not a separate project.
Shelf-level scan signals reveal what shoppers check before buying — and what questions go unanswered at the point of decision.
Verified provenance at the SKU level reduces dispute resolution time for spoilage and claims.

Operations & Quality Teams

Pay for: traceability speed, lot-level audit trails, automated response workflows

When a safety issue surfaces, teams need to scope it in minutes, not days. PureChex provides a signed, lot-level record of where every product went and who interacted with it.
Automated agent workflows can monitor product event streams and flag anomalies before they become incidents.
Audit-ready records reduce the cost and duration of regulatory review.

How It Works

A signed event on every product.

Each product carries a cryptographically signed event — an immutable, verifiable record of origin, content, and handling. That event travels through an open relay network to reach shoppers, brands, and AI agents instantly.

Label as signed event
Each product label encodes a unique, cryptographically signed event containing provenance, freshness, and brand story — tamper-evident by design.
Distributed via open relay network
Events are broadcast to a relay network — independent servers that store and forward product signals without any single point of control or failure.
Verified by any authorized client
Shoppers, retailers, brands, and AI agents subscribe to the relay network and receive verified product events using open, standards-based protocols.
Living product touchpoint
After a scan, the product stays connected — brands push updates, agents monitor signals, and consumers act on trusted information over time.

Features

Built for everyday use and AI-powered follow-through.

PureChex is easy to understand on the surface and powerful behind the scenes. The value comes from what each product can do after it reaches a person, a team, or an automated workflow.

Connected products

Instead of a dead-end label, PureChex creates a living product touchpoint. Each product becomes a reusable, verifiable source of truth — delivering product details, usage guidance, origin stories, and brand updates over time.

Cryptographic signaturesRelay-distributedAlways-fresh

Agent-ready actions

AI workflows subscribe to product event streams and take the next step automatically — sort, route, flag, summarize, and respond without manual review.

Event-drivenStructured data

Consumer trust

Shoppers scan and instantly understand what a product is, where it came from, and whether it's right for them — backed by verifiable, signed provenance data.

Verified originTamper-evident

Direct engagement

Brands stay connected after purchase through a direct protocol channel — updates, care instructions, loyalty experiences, and feedback linked to the specific product in hand.

Post-purchaseBrand-direct

Targeted response

When something changes — a recall, an update, a campaign — the system routes follow-up precisely to the right people around the right product.

Precision routingRecall-ready

Retail intelligence

Every interaction becomes a signal for smarter merchandising. Reveal what people care about, where confusion shows up, and which products earn the most trust.

Use Cases

AI workflow use cases with clear, visible business value.

The strongest opportunity is what software agents can do with product event streams once PureChex becomes the standard product touchpoint.

Customer care agents

Software agents prepare faster responses when customers ask about freshness, sourcing, ingredients, handling, or availability — by subscribing directly to the product event stream.

Answer common product questions instantly from verified event data
Route sensitive issues to the right team with full product context
Summarize customer patterns by product line for support optimization

Safety and recall assistants

When a product issue appears, agents identify where attention is needed and help teams issue focused, targeted follow-up — not broad broadcasts to everyone.

Watch for problem signals across product event streams in real time
Prepare targeted notifications scoped to affected products only
Organize signed case history for fast, auditable regulatory review

Retail and merchandising assistants

Agents learn which products drive scans, what people want to know, and where promotion improves conversion — from the event stream, not surveys.

Open Protocol

Product data shouldn't live in a silo.

PureChex is built on an open, standards-based protocol. Product events are cryptographically signed by the issuer and distributed through an independent relay network — any authorized client can verify and consume product data without dependence on a single platform.

Cryptographic identity
Every event is signed with the brand's cryptographic key pair. Signatures are publicly verifiable — no central authority required to prove authenticity.
Relay-distributed, not centralized
Product events propagate through a network of independent relays. No single server is a point of failure. Clients subscribe to the relay network directly.
Open standards, interoperable clients
Any client that implements the open protocol can read and respond to product events — consumer apps, retail systems, or AI agents. No vendor lock-in by design.
Tamper-evident by design
Signed events cannot be altered without invalidating the signature. Product data integrity is provable, not assumed.

Why Open Protocols

The infrastructure advantage.

Closed platforms create fragile, single-vendor dependencies. Open, relay-based protocols create durable infrastructure that no single company can revoke, shut down, or hold hostage.

No single point of failure

Product event data lives across a relay network. No single server outage takes down the product experience. Redundancy is architectural, not bolted on.

Interoperable by default

Any client that implements the open protocol can read and respond to product events. Brands don't build integrations for every retail system or AI platform.

Verifiable without trust

Cryptographic signatures mean every event can be verified independently. Consumers and machines trust product data without trusting any intermediary.

Traction

Where we are today.

We are in early stages, building with focused partners in food and agriculture — the highest-stakes category for traceability and recall response.

Platform built & tested

Core product event infrastructure — signing, relay distribution, and client verification — is complete and running in controlled environments.

Active pilot conversations

Engaged with produce brands, importers, and supply chain teams in fresh food — the category where traceability failures carry the highest operational and reputational cost.

Domain-deep founding team

Founders with direct experience in international supply chain, cloud infrastructure, global logistics, IoT sensor networks, and post-harvest food systems.

Regulatory tailwind

FSMA 204 traceability mandates are creating a forcing function for exactly what PureChex provides — lot-level digital records, verifiable provenance, and rapid recall scoping.

We are raising a seed round to accelerate pilots and build the relay network with founding brand partners.
