# Tallgrass > Decision Science as a Service. Intelligence before motion. Economics before commitment. Tallgrass is an enterprise decision science platform that unifies four systems — LPS, SKU Surfer, Revlogix, and Digital Product Passport — across seven lifecycle stages. ## Pages - [Home](https://tallgrass.ai/): Decision Science as a Service for enterprises that move physical assets. Introduces the four-system ecosystem (LPS, SKU Surfer, Revlogix, DPP) across seven lifecycle stages. - [Platform](https://tallgrass.ai/platform): The shared platform under every Tallgrass product: unified data model, agentic decision loops, D-Gate governance, and lifecycle economics scoring. - [Products](https://tallgrass.ai/products): Overview of the four-system ecosystem and how LPS, SKU Surfer, Revlogix, and Digital Product Passport compose across one data spine. - [LPS](https://tallgrass.ai/products/lps): Lifecycle Product System — the operational literacy layer that turns heterogeneous product and asset data into a canonical, decision-ready record. - [SKU Surfer](https://tallgrass.ai/products/sku-surfer): AI-driven SKU rationalization, substitution, and portfolio economics based on lifecycle profitability rather than surface velocity. - [Revlogix](https://tallgrass.ai/products/revlogix): Reverse-logistics decision engine that scores disposition (repair, refurbish, resell, harvest, recycle, dispose) against recovered value and cost-to-serve. - [Cost Avoidance with Revlogix](https://tallgrass.ai/products/revlogix/cost-avoidance): How Revlogix prevents waste in transport, handling, warranty exposure, and write-downs through pre-motion decisioning. - [Digital Product Passport](https://tallgrass.ai/products/digital-passport): Tracks asset identity, composition, ownership, service history, and residual value across the seven-stage lifecycle. Aligned with EU DPP. - [Use Cases](https://tallgrass.ai/use-cases): Enterprise use cases by decision type — repair-vs-replace, disposition routing, warranty economics, claim adjudication, M&A valuation, government surplus. - [Industries](https://tallgrass.ai/industries): Industries where lifecycle economics dominate margin: government, ITAD, manufacturing, insurance, recycling, telecom CPE. - [Government](https://tallgrass.ai/industries/government): Public-sector asset portfolios: surplus, seized, decommissioned, and end-of-life assets with auditability, chain of custody, and taxpayer value recovery. - [ITAD](https://tallgrass.ai/industries/itad): IT Asset Disposition: per-device disposition scoring, data-sanitization workflows, resale channel optimization, ESG and compliance reporting. - [Who We Serve](https://tallgrass.ai/who-we-serve): Buyer-persona hub grouped by role and business model: M&A, OEMs, contract repair, CPE producers, insurance, recycling platforms. - [Mergers & Acquisitions](https://tallgrass.ai/who-we-serve/mergers-and-acquisitions): Physical-asset due diligence and post-close value capture: rapid inventory valuation, latent liability detection, unit-economics synergy modeling. - [OEM Manufacturers](https://tallgrass.ai/who-we-serve/oem-manufacturers): Warranty exposure modeling, service-parts economics, refurbished-channel strategy, and design feedback from field-return data. - [Contract Manufacturers for Repair](https://tallgrass.ai/who-we-serve/contract-manufacturers-for-repair): Unit-level repair decisioning, throughput optimization, and shared visibility with OEM clients on economical repair windows. - [CPE Producers](https://tallgrass.ai/who-we-serve/cpe-producers): Customer Premises Equipment fleet lifecycle management, refurbish-vs-replace at scale, and material recovery. - [Insurance](https://tallgrass.ai/who-we-serve/insurance): Total-loss adjudication, salvage disposition, subrogation recovery, and claim triage informed by real recovered value. - [Recycling Platforms](https://tallgrass.ai/who-we-serve/recycling-platforms): Pre-sort by economic outcome, upstream partner reporting, and passport-grade traceability for regulated materials. - [Insights](https://tallgrass.ai/insights): Editorial hub on decision science, lifecycle economics, applied AI, and the operational thesis behind Tallgrass. - [About](https://tallgrass.ai/about): Tallgrass Solutions LLC background, mission, and the origin of the 'intelligence before motion' thesis. - [Contact](https://tallgrass.ai/contact): Contact form and routes for demo requests, partnerships, press, and legal inquiries. - [AIA Hungry Man](https://tallgrass.ai/hungry-man): Signature thought-experiment on autonomous industrial agents (AIA) applied to enterprise asset flows. - [Attainable AI (Book)](https://tallgrass.ai/attainable-ai): Landing page for the Attainable AI book from Tallgrass Press.
