Arcus began as Regalii, a YC Summer 2013 company helping immigrants support relatives abroad. It became payment infrastructure for banks, wallets and retailers. Mastercard acquired it in November 2021. Its Mexican SPEI transfer business still operates; Tapi bought its bill-payment and cash network in June 2025.[4] [8] [11]
The useful lesson is how the team changed its buyer. Serving households required connections to billers and financial institutions. Those connections became a product other businesses could embed. The acquisition preserved that work, but later financial disclosures show that continued operations and profitability are separate outcomes.

Edrizio De La Cruz immigrated from the Dominican Republic to New York. He worked as an aircraft mechanic at JFK while studying at Baruch, entered investment banking in 2005, and earned a Wharton MBA. His account ties the original idea to immigrants' responsibility toward family members back home.[3]
The early team nearly ran out of money. De La Cruz recalls one month of runway in April 2013, followed by pitch competitions, rejected accelerator applications and eventual YC acceptance. He also describes one engineer, one designer and four finance-background salespeople with no sales or remittance-product experience. Personal trust had produced overlapping skills rather than complementary roles. His retrospective identifies a staffing weakness without quantifying the effect of later changes.[2]
YC identifies De La Cruz, Iñigo Rumayor and Juan Maldonado as founders. Maldonado describes operational and product responsibilities; Rumayor describes the earlier cross-border bill-pay company. Mastercard later credited Marc Sacal with helping expand beyond cross-border payments.[4] [8]
The first service sent grocery and bill-payment credits from the US to relatives in the Dominican Republic, then expanded to Mexico.[1]
Regalii developed a white-label API that banks and money-transfer companies could offer through their own channels. It exposed bill balances, due dates, reminders and automatic payments. Supported categories included utilities, phone service, tuition, insurance and loans. Its 2016 release named Sigue, IDT and Compartamos among institutional customers. That model let existing financial brands supply distribution while Regalii supplied biller connections.[6]
By 2018, De La Cruz said more than 40 financial institutions and finance apps used Arcus. He explained the domestic pivot: “we created a better technology than our Mexican bank partners had.” Banorte and Walmart were examples of the Mexican institutions the team began serving. The same interview describes repeated product failures and months of street-level testing before the team found the bill-pay product.[3]
The physical network mattered too. In November 2022, 7pay let customers pay through a numeric reference, QR code or barcode at more than 1,850 7-Eleven locations. Uses included online purchases, service bills and cash deposits to participating digital wallets. Arcus connected a digital business's order to an existing cash counter.[9]
Today's Mastercard-owned Arcus advertises direct SPEI access, interbank account identifiers called CLABEs, payment confirmations, reports and a web/API platform. Its public product page includes reconciliation and account-management features.[12] The director's 2025 report describes the regulated entity's activity as SPEI transfers, excluding cards, cash and foreign currency.[15]
Arcus moved from immigrant households to institutions serving many households and businesses. Mastercard's acquisition announcement named BBVA, Santander, Walmart, 7-Eleven and Rappi. It also identified Sky, Bnext and Cuenca relationships, included a Cuenca testimonial, and described Arcus as a Start Path alumnus.[8]
Its institutional customers bought access to established local connections. A bank could offer recurring bill services without integrating separately with each provider; a retailer could connect cash payments to digital accounts.
The strongest scale evidence measures different things. Regalii's 2016 release reported biller coverage across eleven countries. Mastercard's November 2021 announcement reported operations in seven countries, more than 100 clients and more than 100 employees. Those country counts describe different boundaries and do not establish geographic decline.[6] [8]
Forbes's dated June 2021 profile reported 85 clients, $19 million raised and a $75 million valuation. These are profile figures rather than disclosed acquisition consideration.[7] A global remittance-market estimate does not size the later Mexican enterprise product.
The relevant alternatives changed with the customer. Consumer remittances required household acquisition and trust. Enterprise bill pay competed with banks' own integration work, processors and other local payment networks. Today Tapi operates the acquired aggregation services, while Arcus itself sells regulated transfer access and reconciliation.[11] [12]
Stripe already offers Mexican-peso bank transfers to eligible Mexican businesses through Citi’s local Mexican unit, including automatic handling of partial and excess payments. Its documentation distinguishes confirmation, which can take up to one business day, from settlement at up to T+3. Stripe notes that some confirmations take several days. These timings apply to its service; SPEI itself supports real-time transfers.[13] An independent reconciliation tool needs a specific advantage across accounts, entities and invoice systems beyond these native features.
Regalii licensed its API to financial institutions on a white-label basis.[6] The original company's acquisition price, consolidated revenue at sale, take rate and gross margin were not disclosed in the acquisition announcement.
Later accounts provide a narrower financial picture. Arcus F.I., the Mexican electronic-funds institution, reported MXN143.338 million in commissions and fees charged in 2025, versus MXN48.032 million in 2024. Its operating and comprehensive loss narrowed from MXN37.142 million to MXN7.497 million. These annual figures concern that legal entity, not the original startup's consolidated performance or Tapi's acquired network.[14]
The auditor flagged material uncertainty about continuing operations because accumulated losses reached MXN153.948 million. Management's response cited infrastructure improvements, existing client contracts and a forecast of near-term profits. That forecast is management's expectation, not a realized result.[14]
The June 2026 statements reported year-to-date commissions of MXN70.890 million and a comprehensive loss of MXN11.675 million. They also recorded a MXN30 million shareholder contribution. Customer electronic-funds balances are liabilities and cannot be read as unrestricted operating cash.[16] These disclosures document an operating business that still needs to make its economics work.
Regalii's original experience required biller connectivity regardless of how convincing its consumer interface became. Selling that connectivity to banks increased the number of end users one commercial relationship could reach. The founder's account supports a domestic-market pivot after repeated product experiments, rather than a smooth progression from a fully proven consumer business.[3]
This interpretation has limits. The available figures do not isolate consumer acquisition costs from enterprise sales costs or prove that every pivot improved margins. What they do show is a change in product, buyer and distribution channel, followed by institutional adoption.
Mastercard's acquisition announcement emphasized existing relationships and SPEI approval.[8] The later IFPE authorization expanded the regulated institution's permitted activity. CNBV's September 2023 letter still required operational prerequisites before launch. Arcus's director report dates electronic-funds transactions from December 2024.[10] [15] A license announcement cannot substitute for readiness to operate a financial product.
Tapi's June 2025 announcement explicitly separated bill payments, mobile top-ups, gift cards and cash operations from Mastercard's retained SPEI processing, settlement and reconciliation.[11] Regional aggregation may fit Tapi's network strategy, while regulated transfer infrastructure fits Mastercard's stated real-time-payments strategy. Neither statement discloses the seller's transaction economics or establishes that the two businesses had incompatible margins.
The later Mexican entity accounts add a separate caution. Revenue growth can coexist with losses and an auditor's continuity warning.[14] They cannot explain the 2021 acquisition or prove why the 2025 network sale happened.
