Optimal Dynamics is not a fuel stop planner. Its public site describes a Transportation Decision System for truckload carriers and private fleets that automates dispatch, load acceptance, freight procurement and bid analysis; fuel appears there as a cost that fewer empty miles reduce, not as a product. ValveRide Flow, The Fuel Decision Layer, decides where each truck fuels and how many gallons to buy, so a fleet can run both.
We make Flow. Every Optimal Dynamics claim below comes from their own public website and is dated in the sources note.
Optimal Dynamics describes itself as the first comprehensive Transportation Decision System, built to boost utilization, productivity, and profitability for enterprise trucking companies. Its public site lists dispatch management, network management (freight procurement), bid analysis, network simulation, and business strategy, all running on one decision engine across strategic, tactical, and real-time planning horizons.
Its dispatch recommendations factor in HOS, home time, and driver location to assign loads and tours, and its site describes TMS and ELD integrations plus an API. For a carrier whose hard problem is which driver takes which load and which lanes to bid, that is a serious, purpose-built platform.
Flow starts after the load is assigned. For each dispatch it decides where the truck should fuel and how many gallons to buy at each stop, using the fleet's own contract discounts, live prices at 7,500+ US truck stops, IFTA state fuel tax across 48 states with data, ELD fuel level, and hours of service timing. It keeps re-planning for the whole trip and offers alternate stops when the plan changes.
It also watches the fuel itself: card transactions are screened for anomalies, and a tank that drops while the truck is parked with no matching fill is surfaced for dispatch to review. The published result is about $0.90 per gallon saved, blended across live fleets over the trailing 12 months, and 100% of claimed savings reconciled against actual fuel card transactions.
Running both is straightforward. Optimal Dynamics assigns the load, the dispatch lands in the TMS, and Flow builds the fuel plan for that trip and sends it to the driver. Dispatch keeps its decision engine, fuel gets its own, and neither has to be replaced to add the other.
| Optimal Dynamics | ValveRide Flow | |
|---|---|---|
| The decision it makes | Which driver takes which load, which loads to accept, which freight to procure, and which lanes and RFPs to bid, per their site | Where each truck fuels, how many gallons to buy at each stop, and on which contract |
| Main inputs | TMS and ELD data, HOS, home time, driver location and preferences, forecasted freight demand, per their site | Negotiated fuel contracts, live truck stop prices, IFTA state fuel tax, ELD fuel level, HOS timing, and the dispatched route |
| Planning horizon | Strategic, tactical, and real-time dispatch decisions on one engine, per their Decision Automation page | Each dispatched trip, re-planned for the whole trip as the route, prices, position, or HOS clock change |
| Fuel | Their materials describe lower fuel expenses as a result of fewer empty miles; no fuel stop or fuel purchasing product is listed on their public site as of October 2026 | Fuel purchasing is the product: contract discounts, IFTA, alternate stops, out-of-route alerts, and fuel theft watch on card transactions and parked trucks |
| Connections | TMS and ELD integrations plus an API, per their Partner Integrations page | Any TMS by webhook or API. Flow can receive dispatch information from Samsara, Motive, and Isaac instead of from your TMS. Plans reach drivers by SMS, email link, or in-cab message on Samsara and Isaac |
| Proof published | Customer case studies on planner productivity and revenue per truck | about $0.90 per gallon saved, blended across live fleets over the trailing 12 months, reconciled against actual fuel card transactions |

Not in the fuel stop sense. Optimal Dynamics' public site describes a Transportation Decision System that automates dispatch, load acceptance, freight procurement, bid analysis, and network simulation for truckload carriers. Fuel appears as a cost that fewer empty miles reduce. It does not list a product that picks fuel stops or gallons. ValveRide Flow does that job.
Its materials say better network planning means fewer empty miles and lower fuel expenses, which is a real, indirect effect. They do not describe choosing where a truck buys diesel. ValveRide Flow handles that purchase decision: which stop, how many gallons, on which contract, with IFTA state fuel tax and hours of service in the math.
For fuel, it is the piece Optimal Dynamics does not list, not a replacement. Optimal Dynamics decides which driver takes which load. ValveRide Flow, The Fuel Decision Layer, decides where that truck fuels and how many gallons it buys, using the fleet's contract discounts, live truck stop prices, IFTA, and HOS timing.
Yes. They make different decisions about the same dispatch. Once a load is assigned and lands in the TMS, Flow builds the fuel plan from that dispatch by webhook or API. Flow can receive dispatch information from Samsara, Motive, and Isaac instead of from your TMS. Flow does not change how loads get assigned.
The published figure is about $0.90 per gallon saved, blended across live fleets over the trailing 12 months. It is not a per-fleet guarantee: results depend on each fleet's lanes, contracts, and fueling habits, and every claimed dollar is reconciled against the actual fuel card transaction. Pricing is per truck, never per driver.
