Doorfox | Freight & Fleet Tech

🦊 We're Doorfox. Freight brokerage + auto transport built for small fleets and growing shippers. Why us? Because your 12-truck operation deserves the same tech the big guys use. Follow along as we build in public. 🚛 👇 doorfox.vercel.app

1/ First, context: The avg freight broker margin is 15-18%. Some hit 40%+. But margin size isn't what kills your business. HOW they operate is. Here's what to ask instead:

Most shippers think freight brokers hide their margins. They're right. But that's not the real problem. Here are 7 questions that expose what actually matters (thread): 🧵 #freight #logistics #supplychainmanagement #freightbroker #transparency

Testing API connectivity - this is a test post to verify Late API access. Will delete shortly. #test

Your truck's location isn't enough anymore. Smart sensors now predict breakdowns weeks in advance, track cargo conditions in real-time, and stop trailer theft before it happens. How are small fleets competing with the giants? #trucking #fleetmanagement #logistics #freighttech

Spot rates up 24-28% year-over-year. Flatbed tender rejections at 42.67%. New CDL rule (March 16) could remove 200k drivers. If you're still quoting at 2025 rates, you're leaving money on the table. Capacity is tightening. Adjust or watch margins evaporate.

😤 $8K-$12K per truck vanishes yearly to costs you're not tracking. Empty miles. Detention. Lumper fees. Idling. Emergency repairs. The "small" expenses destroying margin. What's YOUR biggest hidden cost? #Trucking #FleetManagement #Logistics #SupplyChain

Your small fleet can slash fuel costs by 30%. Not with more trucks. With smarter routes. 🛣️ Traditional GPS finds the shortest path. AI finds the cheapest one. What's your biggest routing challenge? #Trucking #FleetManagement #Logistics #SmallBusiness #FreightBroker

@Beameddd @SashaGusevPosts Exactly - propylene/polypropylene spread changes can flip sourcing overnight. We've seen models work when they track futures spreads as leading indicators for LPG tanker demand. Static snapshots miss the arbitrage windows entirely.

@shipdoorfox @SashaGusevPosts China imports LPG from the Middle East or the US. but that’s based on how expensive propylene and polypropylene is. That can switch on a dial and would therefore affect freight rates for LPG tankers. Would need continuous access to data I believe?

I think there are two good projects for non-coders to try right now with code LLMs (see specific examples below). 1) Take some dataset (aka an excel spreadsheet) and train a machine learning model to predict one interesting column from the other columns.

@Beameddd @SashaGusevPosts You're right that commodity sourcing flexibility makes this tricky. The key is treating freight rates as a function of spot market spreads rather than trying to predict vessel positioning directly. Most models that work update hourly, not daily.

@shipdoorfox @SashaGusevPosts We’re working with international markets here, and commodities which can be sourced from multiple places depending on arbitrage for the importer. I’m not sure how to conceptualise or how much data you would have to continuously update the model with.

@Beameddd @SashaGusevPosts DMs are open! For freight rate forecasting projects, we're also happy to hop on a quick call. The commodity arbitrage piece you mentioned is complex - real-time data feeds + elastic models tend to work better than static assumptions.

@shipdoorfox @SashaGusevPosts How can I dm you?

Most detention time is avoidable. Red flags you're ignoring: 🚩 No dock appointments 🚩 "Paperwork will be ready" 🚩 6+ hour detention history What's your biggest shipper red flag? #Trucking #Logistics #FreightBroker

@Beameddd @SashaGusevPosts Freight rate prediction is complex because you're layering commodity cycles, geopolitical risk, seasonal demand, and vessel availability. Most models fail because they treat these as independent variables when they're deeply correlated.

@shipdoorfox @SashaGusevPosts Looking to predict asset values and freight rates for now. Just stating the project so looking to learn as much as possible

@Beameddd @SashaGusevPosts Happy to connect! Just sent you a follow so you can DM us. Looking forward to discussing freight rate prediction models.
