Quick Answers

The Four Things You're Wondering Right Now

Every EA who lands on this page has the same four questions in mind. Here are the answers — before you have to ask.

Flight rebooked at 5 AM into MIA?

Already adjusted. Real-time flight tracking on every booking. The chauffeur repositions automatically. No call needed. You don't need to know.

Need to know where the car is right now?

Live GPS in your dashboard. Pickup and drop-off notifications pushed to you automatically. Share live tracking with your principal or security team in two taps.

Last-minute itinerary change at 11 PM?

You text Nate. He answers. Direct line to the operator who runs the company — not a dispatch queue, not a call center. 24/7, every day of the year.

New city, unknown chauffeur?

Vetted by Nate personally. Partner operators in NYC, LA, London, Paris, Geneva, Dubai run on the same platform. Same standards. Same invoice. Your principal is never with a stranger.
The Job No One Sees

Until Something Goes Wrong

You're the person who makes sure the CEO lands, the board gets to their meetings on time, and your principal never thinks twice about how it happened. When it works, no one notices. When it doesn't, everyone does — and it reflects on you. The four pains below are the ones we hear from every EA we talk to before they switch. If any of them feel familiar, this page is built for you.

Invoices that don't add up.

Wrong pickup times. Wrong amounts. Receipts that arrive a week after month-end. We've heard one story where an EA was charged for another client's rides entirely. By the time you sort it out with finance, you've spent two hours of your day on a $340 transfer.

“Companies stop sending proper invoices. The receipts have wrong amounts. I have to email every company to get them.” — EA, family office

Chauffeurs who hide what they shouldn't.

Premium price. Cigarette smoke in the cabin masked with cheap perfume. A driver who can't find Brickell at 3 AM. A car that arrives 12 minutes late with no apology. Your principal notices. You hear about it.

“Chauffeurs smoke in the car and try to hide it with perfume. Premium price, low service.” — EA, investment banking

Information you have to chase for.

You don't get the chauffeur's name unless you ask. You don't know your principal's been picked up unless you call. You don't see the drop-off until the receipt shows up next week. You're a dispatcher for a service you're paying premium prices for.

“I have 500 things on my plate. I don't have time to ask every time — can you send me the chauffeur info, can you send me this.” — EA, single-family office

No transparency. No accountability.

What's the rate? “We'll send the receipt later.” Who's the chauffeur? “He'll be there.” What if the flight changes? “Just call dispatch.” Every answer points downstream. No one owns the ride.

“The differentiating factor isn't visible. It looks like every other site, every other vendor.” — EA, on the previous version of Osmos Black's site
What Changes With Osmos Black

The Platform That Removes the Chase

Osmos Black was built around the workflow of the person who books. Not the principal. You. Every system, every protocol, every piece of communication is designed to take work off your plate — not add to it.

01

One platform. Every invoice. Always there.

Every receipt is automatically logged in your corporate account, organized by date and passenger. Consolidated monthly invoicing for finance teams. Export-ready for SAP Concur, Expensify, Ramp, and Brex. You stop emailing for receipts. They're already there.

02

One stored card per principal.

Your principal's banking information lives in one secure system — not scattered across a dozen vendor accounts. Black-card holders especially appreciate this. You add the card once. Every ride bills to the right principal. Every invoice is consolidated.

03

Chauffeur details before pickup. Always.

Before every ride: name, photo, vehicle, plate, languages spoken. Pushed to you — you don't ask. Forward to your principal in two taps, or keep it for your records. Real-time pickup and drop-off notifications follow automatically. You know where the car is. You know when your principal is moving.

04

One owner. One standard. Direct line.

Your point of contact is Nate — the operator who runs the company. Not a rotating dispatcher. Not a call center agent. He briefs every chauffeur in our fleet personally and vets every partner operator for out-of-state rides. Reachable by phone, text, or email, 24/7. The buck stops on his line.

A Tuesday Morning

What This Actually Looks Like On the Calendar

A real scenario. Your principal — let's call her your CEO — is flying back from Newark at 8:42 AM Tuesday into MIA. She has a 10:30 AM at the office in Brickell, then a lunch in Coral Gables, then back to MIA for a 5 PM departure. Here's what your morning looks like.

Monday evening, you booked the day. One reservation: airport pickup at MIA, hourly chauffeur from 10:30 AM to 3 PM (three stops), drop-off at MIA Terminal D. You added flight number, terminal, and a note about her preferred water temperature. Confirmation came back in under an hour with the chauffeur profile — Carlos, 8 years in luxury chauffeur service, English and Spanish.

At 6:14 AM Tuesday, the flight changed. Newark held her for 22 minutes due to weather. Osmos Black already knew — flight tracking is automatic. The chauffeur repositioned. Nothing on your phone, nothing on your calendar, nothing in your inbox. The system just adjusted.

At 8:38 AM, your principal lands. You receive an automatic notification: “Pickup confirmed at MIA Terminal D — Carlos onboarding now.” She walks out, her chauffeur is at the curb with a name board, the door is open before she reaches it.

At 10:24 AM, you receive a drop-off notification at the office. 1:08 PM, the lunch stop. 3:02 PM, departure for the airport. 4:41 PM, arrival at MIA Terminal D. You haven't called Osmos Black once. Carlos has the next pickup of his day already in his calendar.

End of month, your account shows one invoice. Carlos's seven hours, one airport transfer in, one airport transfer out. Tagged to the principal, exportable to Concur, billed to the card on file. No reconciliation, no follow-up emails, no phone calls. You ran your day.

How It Works

From Booking to Invoice — Four Steps

No portal to learn. No vendor onboarding paperwork. You book the way you already work — phone, text, email, a 60-second web form, or our Passenger App (PWA) that installs in 10 seconds without the App Store. Same reservation, whichever channel you pick.

01

Request

Phone, text, email, or web form. Add flight number, principal name, and any preferences. Same-day bookings handled within 1–2 hours. Confirmation back to you, not to your principal.

02

Confirm

You receive the chauffeur profile — name, photo, vehicle, plate, languages — before pickup. Forward to your principal in two taps, or keep for your records. No further action needed.

03

Track

Pickup and drop-off notifications pushed to you automatically. Real-time vehicle location on dashboard. Flight delays handled by the system without a phone call.

04

Invoice

Receipt automatically logged in your corporate account, tagged to the right principal, billed to the right stored card. End-of-month consolidated invoice exports to Concur, Expensify, Ramp, or Brex.

From the People Who Book

Trusted by the Assistants Who Coordinate

Real reviews from real EAs. We've protected names where requested. Industry signals are accurate.

I coordinate ground transportation for multiple high-net-worth principals. With other car services I had to email for invoices, ask for chauffeur details, call to confirm pickup. With Osmos Black it's all in the platform before I even ask. One stored card per principal — that mattered most. My clients have black cards and they don't want their banking info scattered across vendors.

The fixed pricing — that's what changed my workflow. I see what we're paying from the start. No surprises at month-end, no calls to finance to explain a surge charge. And when our CEO's flight rebooked at 5 AM into MIA, the chauffeur was already there. I didn't even know there was a delay until afterward.

Common Questions

What EAs Ask Before They Book

Available 24/7 across South Florida. Direct line: 786-530-4770. The owner answers.

Same-day bookings are standard. Two hours' notice is ideal. Airport transfers can often be confirmed within one hour. For the fastest response, call or text 786-530-4770 directly — you reach the operator, not a call center.

Yes. The chauffeur's name, photo, vehicle make and model, and license plate are sent to you before every pickup. You can forward this directly to your principal or keep it for your records. You never have to ask. This is the platform standard for every corporate-account ride.

Every receipt is automatically stored in your corporate account, organized by date and passenger. One stored card per principal — banking information stays in one secure system rather than scattered across vendors. Consolidated monthly invoicing is available for finance teams and is export-ready for SAP Concur, Expensify, Ramp, and Brex. Open a corporate account →

Every commercial flight is monitored in real time. The chauffeur adjusts automatically for delays, early arrivals, and gate changes. You don't need to call us — we already know. For private aviation arrivals at OPF, FXE, BCT, or PBI, share the tail number at booking and we coordinate directly with your FBO.

Yes. A single Osmos Black corporate account supports unlimited principals with individual preferences, separate trip histories, and consolidated billing under one corporate account. You book on behalf of any principal from one device.

Yes. Standing reservations cover recurring schedules — weekly airport runs, daily commutes, Monday morning pickups, Friday departures. Set them once. They run automatically. Modifications by text or call same-day at 786-530-4770.

Osmos Black coordinates a vetted partner-operator network across major business cities — New York, Los Angeles, London, Paris, Geneva, Dubai. Partners are personally vetted by Nate, run on the same platform with real-time tracking, and follow the same communication protocol. You book once, we coordinate locally, you receive one invoice and one confirmation flow.

Discretion is baseline, not an upgrade. NDAs are available on request. Vehicles are unmarked black — no logos, no decals, no plate frames. Banking information stays in one secure system. Chauffeurs are briefed on principal-specific protocols and work with personal security details and advance teams when required.

Fixed rates confirmed at booking. No surge pricing. Event weeks (F1 Miami, Art Basel, FIFA 2026, Miami Open) carry premium rates that are locked at booking, not added later. You see what you'll pay from the start. Corporate accounts receive negotiated rate sheets for high-volume bookers.

Yes. Fully licensed and insured in the State of Florida. Commercial insurance on every vehicle. Owner-operated by Nate Medoit. Available 24/7, 365 days a year. Trilingual support (English, French, Spanish). Direct line: 786-530-4770. Email: nate@osmosblack.com.

No. You (the EA or travel manager) are the primary contact with the chauffeur — by default. The chauffeur profile is sent to you before every pickup. Real-time pickup, en-route, and drop-off updates are pushed to you via your channel of choice: our Passenger App (PWA), SMS text, WhatsApp, or all three at once. Privacy is the default, not the upgrade.

Risk-Free Trial

Try the Discovery Drive. One Ride. Zero Risk.

Book one ride. If we don't make your day easier, you don't book again.

Most EAs we work with discover the platform on their first ride. The chauffeur details arrive before the airport. The drop-off notification lands while they're still on a call. The receipt logs to the account before they have to ask. By the time they get to month-end, they've stopped looking for another car service. We invite you to test that on one ride. No corporate-account commitment. No vendor onboarding paperwork. Just a phone call.
