What Peltier does

Peltier Technology Inc. is a San Francisco-based deeptech company that builds a Modular Cold Chain (MC²) ecosystem — a hardware-plus-software platform for active, refrigerant-free, IoT-connected temperature control. The platform combines the Peltier Tote™, a portable tri-temperature unit (frozen, chilled, ambient) using solid-state thermoelectric cooling licensed exclusively from Phononic, with the Peltier Framework™ (racks and carts that adapt totes to manual or automated fulfillment centers) and the Peltier Cloud™ SaaS layer, which streams 50+ telemetry points per tote for temperature, location, and compliance and integrates via API with ERP and fulfillment systems.

The company's go-to-market is enterprise-focused, with named deployments or pilots at Walmart, Meijer, ShopRite, and Quest Diagnostics spanning grocery, pharmaceutical, biotech/life sciences, e-commerce/logistics, and disaster relief verticals. A flagship January 2026 partnership with OPEX Corporation embeds Peltier Totes inside OPEX's Perfect Pick, Infinity, and iBOT automated storage and retrieval systems, positioning Peltier as the cold-chain layer for automated fulfillment. Revenue is generated through hardware sales (Totes and Framework) plus recurring SaaS subscriptions (Peltier Cloud), with custom enterprise pricing and a stated ROI of roughly 14 months when replacing traditional reach-in and walk-in refrigeration.

Founded in 2024 by CEO Hanson Li (formerly Chairman of Humphry Slocombe), Peltier is a privately held company incorporated in Delaware. As of early 2026 it had filed an SEC Form D reporting $5,604,998 sold to 30 investors against a $7,855,000 target and announced an oversubscribed funding round in April 2026, and it has 11-50 employees operating from 123 Valencia St, San Francisco, with claims of a strong international supply chain and a self-reported base of 500+ clients.

Core offering

Peltier sells the Modular Cold Chain (MC²), an integrated hardware-plus-software ecosystem for the cold chain. The physical units — Peltier Tote™ portable tri-temperature solid-state cooling containers and Peltier Framework™ power racks and carts — are sold to enterprise customers and are paired with Peltier Cloud™, a subscription software platform that streams real-time telemetry, compliance data, and API integrations to ERP and fulfillment systems.

Product overview

Peltier offers a platform-plus-modules architecture called the Modular Cold Chain (MC²), the world's first scalable, solid-state cooling ecosystem. The core product is the Peltier Tote — a portable, tri-temperature unit (frozen, chilled, ambient) that eliminates refrigerants and delivers precise temperature control within one degree. Two supporting modules extend its functionality: Peltier Framework (racks and carts that add power infrastructure and modularity to the Tote network) and Peltier Cloud (software connecting every Tote for real-time telemetry, compliance reporting, and ERP/fulfillment system integration). Together they enable organizations to replace expensive, rigid refrigerated warehouses with modular, precise, and sustainable cold chain solutions.

Direct peers

• HELMER Scientific: Designs and manufactures medical-grade refrigerators, freezers, and temperature-controlled storage for hospitals and pharmacies. Overlaps with Peltier's pharma/healthcare vertical on precision, compliance, and audit-ready cold storage.
• va-Q-tec: Specializes in high-performance thermal insulation and phase-change material solutions for pharma cold chain. Comparable to Peltier on serving the same regulated temperature-sensitive parcel market with a hardware-plus-service model.
• Cold Chain Technologies: Provides thermal packaging and temperature-controlled shipping solutions for pharma and life sciences. Directly comparable to Peltier's refrigerated totes/parcels use case, especially for vaccine and biologic transport where passive and active solutions compete.
• Sonoco ThermoSafe: Global provider of temperature-assured packaging for pharma, food, and e-commerce cold chain. Competes with Peltier in parcel-level cold chain, particularly for last-mile temperature-controlled DTC and clinical trial shipments.
• B Medical Systems: Manufactures medical-grade cold chain equipment including vaccine cold boxes and blood bank refrigerators. Comparable to Peltier's pharma/healthcare cold chain offering, particularly for vaccine storage and last-mile transport in regulated settings.

Broad incumbents

• Thermo Fisher Scientific (Cold Storage): Large incumbent serving life sciences and pharma with cold storage, ULT freezers, and sample management solutions. Serves the same Quest Diagnostics-type enterprise accounts with established channels and broader portfolios.
• Thermo King (Ingersoll Rand): Dominant supplier of transport refrigeration units for trucks, trailers, and containers. A broad incumbent in temperature-controlled logistics whose installed base and dealer network represent a long-term competitive threat to Peltier's transport-adjacent offerings.
• Carrier Commercial Refrigeration: One of the largest commercial refrigeration equipment manufacturers, supplying grocery, food service, and cold chain operators. A direct incumbent Peltier aims to displace with its solid-state, refrigerant-free platform.

Regional players

• Americold: Largest publicly traded temperature-controlled warehouse operator in North America, operating the kind of fixed refrigerated warehouses Peltier aims to replace or complement with modular totes. Operates at the storage layer of the same grocery/pharma cold chain.

Others

• OPEX Corporation: Peltier's strategic technology partner, but also an adjacent warehouse automation peer whose Perfect Pick / Infinity / iBOT systems integrate Peltier Totes. Comparable as a peer in automated fulfillment where the cold chain layer is now an attachment point.
