A customer wants to buy. A merchant wants to sell. Between those two agreeable parties sits a surprisingly crowded room: advertising platforms, checkout software, card providers, account reviews. Matthew Sabia has made a career around the doors in that room. He has taught people how to attract customers, worked in the business of getting advertisements delivered, and now, through Railbed, is concentrating on getting a completed sale to the merchant's wallet.
There is a neat progression here, though the businesses wear different clothes. An online marketing tutorial offers a route to attention. An advertising service offers access to the machinery that distributes it. Checkout software deals with the next transaction. Follow Sabia through DeepWork, MediaGlobe and Railbed, and the recurring subject is the working space between a business owner and a platform with the power to say no.
Sabia is an American entrepreneur, digital marketing executive and creator based in Connecticut. He founded DeepWork and is co-owner and chief marketing officer of MediaGlobe. His current focus is Railbed, where he is founder and CEO. The latest venture takes a familiar online-business frustration and gives it a specific destination: card payments that become USDC in a wallet controlled by the merchant.
It is a less glamorous subject than the lifestyle often attached to internet entrepreneurship. A checkout rarely gets invited onto a yacht. But for someone whose public work has revolved around selling online, it is a consequential place to spend time. Attention can bring a customer to the counter. The counter still has to work.
Before the checkout, a camera
Sabia's earlier public work had a more conversational setting: YouTube. His channel contains tutorials about Shopify, affiliate marketing, email marketing and finding customers through social platforms. These are practical topics with an impatient audience. People searching for help with an online store generally want to know what to click, what to change and what they will have to pay.
A June 2018 video carried the title “How I Got Instagram Influencers To Promote My Products For FREE.” Its opening addressed a small merchant's arithmetic: paying hundreds of dollars for an influencer post can feel like a considerable commitment when a business is just starting. The subject was an approach to promotion, but the appeal rested on a recognizable constraint. A beginner has ambitions; the advertising budget may have other plans.
That year, he also published a tutorial on accepting Bitcoin through Shopify. Seen alongside Railbed, the topic provides an early point of contact between his teaching work and alternative payment methods. The two projects belong to different moments and use different arrangements. Still, payments were already part of the set of problems he was explaining to online merchants.
His creator identity has continued alongside his business roles. The channel describes itself through DeepWork and MediaGlobe and directs viewers to a separate Spanish-language channel. A tutorial library has a different rhythm from a social feed: an old explanation can remain available while the person who recorded it moves on to the next company. For Sabia, those videos leave a visible record of the questions that occupied him before Railbed.
A company named for concentration
DeepWork's company profile dates its founding to 2018 and places it in Monroe, Connecticut. It describes an investment business focused on online assets and real estate, with an emphasis on the operators who run its companies. The name is consistent with a theme Sabia has returned to publicly: the value of concentrating effort rather than scattering it across an ever longer list of opportunities.
In a 2022 account of his career, Sabia recalled beginning with more than $50,000 in credit-card debt. He described focus and discipline as central to the way he moved forward. The anecdote is his account of that period, rather than a balance sheet, but it gives his insistence on concentration a personal frame. In that telling, the problem preceded the polished company names.
His advice in the same account was to back entrepreneurial effort with “keen focus, simplicity, and discipline.” These are modest-sounding words for a field fond of extravagant thumbnails. They also describe a demanding routine. Choosing one line of work means leaving other plausible lines alone, even when the internet supplies fresh invitations by the minute.
The combination of education and ownership matters in his career. Teaching a merchant how to run a store and backing a business operator put him on different sides of the same conversation. One requires an explanation someone can follow. The other requires a business someone can keep operating. DeepWork gave those interests a company around which to gather.

The advertising account becomes the product
At MediaGlobe, Sabia's work moved closer to the infrastructure of paid advertising. The company offers agency advertising accounts and consulting for businesses buying traffic on platforms such as Meta and TikTok. Its pitch centers on the account itself: the practical ability to run campaigns, manage spending and get help when platform rules complicate an advertiser's plans.
This is a recognizable shift from teaching a technique to providing a service. A useful video can explain a campaign. A merchant spending money every day may also want an account manager who answers questions about policy or media buying. MediaGlobe's offering places those operational needs alongside access to advertising accounts.
Sabia's role combines ownership with marketing leadership. It sits naturally beside his creator work, where the job is to explain an opportunity in language an owner can understand. But the business also makes the limits of persuasion plain. A convincing advertisement does little for a merchant whose account cannot run it. The delivery mechanism has become part of the offer.
His public professional identity has consequently accumulated several nouns: founder, marketer, investor, creator. Each catches a different piece of the work. The common thread is easier to see through the customer's tasks. Find a product, get it in front of people, keep the campaign running, collect the sale. Railbed takes up the last of those jobs.
A card comes in. A wallet gets paid.
Railbed describes itself as checkout software operated by MediaGlobe. The relationship gives Sabia's latest focus an organizational connection to his advertising business. Its proposition is aimed at online merchants whose categories can make mainstream payment services difficult to use, including digital goods, online courses, dating services and adult creator businesses operating within its rules.
The company lays out a sequence. A merchant publishes a payment link or checkout, or connects an application through the API. A customer pays through an independent on-ramp provider, which handles the card payment and conversion. USDC then moves over the Polygon network to the merchant's wallet through a payment infrastructure partner. Railbed says it does not take custody of the funds.
The distinction matters to the story Sabia is now telling. Railbed presents the removal of a held merchant balance as its answer to frozen payouts. The buyer begins with a familiar card purchase; the merchant receives a different form of settlement. The product puts that handoff at the center of its pitch, rather than asking the merchant to begin by teaching every customer about cryptocurrency.
There is also a routing layer. Railbed describes software that recommends an on-ramp provider using factors including the payment amount and the buyer's location. Providers make their own acceptance and identity-check decisions. Its terms explicitly leave room for a payment to be declined or identification to be requested. Those details are part of the actual arrangement behind the brisk promise of an easier checkout.
For Sabia, the move is a change of emphasis within familiar territory. He has spent years addressing people who sell through software they do not fully control. Railbed's chosen response is a product design in which the merchant controls the destination wallet. The aspiration is built into that architecture: reduce the part of a completed sale that remains out of the seller's hands.

The work behind a short promise
Railbed's developer documentation shows what must sit beneath a short sales pitch. There are checkout sessions, payment statuses, signed webhooks and separate test and live modes. A store needs to know when an order has actually been paid before it delivers the goods. In the documentation, that decision rests on a verified payment event or an authenticated status check.
The range of integrations also tells something about the intended audience. A merchant can use links and buy buttons without building a custom checkout. A developer can connect an existing app. Those paths meet at the same business event: a payment that the seller's system can recognize and act on. This is where the creator's knack for explaining steps meets the less theatrical work of documenting them.
The boundaries are equally concrete. Railbed's acceptable-use policy requires legal sales in the merchant's and buyer's locations and compliance with the providers' rules. It prohibits deceptive selling and unsupported income claims, among other activities. Independence, in this product, still comes with terms. A page promising a simpler route to payment has a substantial amount of detail behind its front door.
Sabia's career is now easiest to read from the merchant's end of the transaction. His early videos asked how a small business might get attention without exhausting its budget. His advertising work addressed the tools needed to reach customers. Railbed asks where the proceeds go once the customer pays. The subjects have grown more operational, while the person he is addressing remains much the same.
That gives the next chapter a practical measure. An entrepreneur can collect titles, accounts and audiences; a merchant still needs the purchase to finish. Sabia's current work puts him at that final handoff, after the persuasive words have done their job. The customer has said yes. There is a sale to complete.
