Nauta vs. RELEX Solutions: Planning Recommendations or Autonomous Execution?
Nauta and RELEX Solutions solve different problems. RELEX is a retail and supply chain planning suite: it forecasts demand, plans replenishment, and recommends what to order across stores and distribution centers. Nauta is an operational brain: it unifies live data from ERP, TMS, WMS, emails, and PDFs, then deploys AI agents that execute on exceptions across supply chains. If your gap is planning accuracy in retail, RELEX is a strong fit. If your gap is what happens after the plan, when containers slip, suppliers miss, and margin leaks, Nauta closes it.
What is RELEX Solutions?
Founded in Helsinki in 2005, RELEX Solutions serves 600+ retailers, wholesalers, and manufacturers with a unified planning suite covering demand forecasting, replenishment, inventory, merchandising, pricing, promotions, and workforce planning. It has been named a Leader in the Nucleus Research Enterprise Supply Chain Planning Value Matrix and has expanded into manufacturing planning, supporting nearly 140 manufacturers. In 2026 RELEX added agentic AI capabilities and its Rebot assistant on top of the planning core.
RELEX's center of gravity is the plan. Its strongest results come from forecast accuracy, waste reduction, and automated replenishment in grocery and retail environments with dense point-of-sale data.
What is Nauta?
Nauta is the operational brain powering your supply chain agents. It connects fragmented operational data into a single AI-native data layer, then puts purpose-built agents to work on it: predicting stockouts 5 to 14 days out, chasing suppliers, resolving document exceptions, and catching freight anomalies before they hit the P&L. Agents act. Humans decide. A food and beverage distributor lifted fill rate from 74% to 90% and held it there.
The core difference: a plan is not an operation
RELEX answers the question every planner asks: what should we buy, where, and when. Nauta answers the question every operator lives with: the plan just broke, now what. A forecast does not call the supplier when the PO slips. A replenishment recommendation does not clear the container stuck at port or dispute the demurrage invoice. Planning tools stop at the recommendation. Nauta's agents carry the chain to execution: order placed, container cleared, margin protected.
There is also a data difference. RELEX runs on structured transactional data. Nauta was built for the reality of import-heavy operations, where the truth lives in emails, PDFs, supplier portals, and spreadsheets. The brain ingests unstructured data automatically and learns from every action the agents take, so the core gets harder to copy over time.
Nauta vs. RELEX: side by side
| Nauta | RELEX Solutions | |
|---|---|---|
| Category | System of Action: autonomous execution | Planning suite: forecasting and recommendations |
| Core buyer | Import-heavy distributors, manufacturers, CPG operators | Retailers, grocers, wholesalers with dense POS data |
| Data handled | Structured + unstructured (emails, PDFs, portals) | Primarily structured transactional data |
| AI role | Purpose-built agents that execute on exceptions | Forecasting models plus assistive agentic features |
| End of chain | Execution: order placed, container cleared | Recommendation: plan handed to humans |
| Time to value | Integrations in under 20 IT hours | Enterprise planning implementations, typically months |
Who should choose which
Choose RELEX if you are a retailer or grocer whose main lever is forecast-driven replenishment across hundreds of stores. Choose Nauta if you run inbound supply chains where the daily fight is suppliers, containers, documents, and landed cost, and where you need action taken, not another recommendation queue. Many operations run both: RELEX plans, Nauta executes.
The bottom line
RELEX tells you what to plan. Nauta runs what happens next. If your losses come from execution, missed POs, stuck containers, invoice leakage, the operational brain is the layer you are missing.

Frequently Asked Questions
Is Nauta a replacement for RELEX?
Not directly. RELEX is a planning suite; Nauta is an execution layer. Nauta replaces the manual coordination that happens after the plan: chasing suppliers, resolving exceptions, protecting margin.
Does RELEX execute actions autonomously?
RELEX automates planning outputs like replenishment orders and has added agentic AI features, but its core deliverable is a recommendation for humans to act on. Nauta's agents act on live exceptions end to end, with humans deciding what matters.
Which deploys faster?
Nauta connects to existing ERP, TMS, and WMS systems in under 20 IT hours without rip-and-replace. RELEX deployments are enterprise planning projects that typically run on longer timelines.
