Overview
Flywire is not really a cross-border payments company in the generic sense — it is vertical payments software. The Boston company, founded in 2009 as peerTransfer by MIT graduate Iker Marcaide after his own frustrating experience paying tuition from a European bank, builds its business by embedding a global payments network and industry-specific software directly into clients’ accounts-receivable workflows (FinTech Magazine; Built In Boston). Its hunting ground is the high-stakes transaction: once a payment exceeds $10,000, different regulations apply and funds must move through purpose-built networks — which is where Flywire positions itself, serving universities, hospitals, travel operators and B2B firms (Finovate).
From tuition payments to four verticals
peerTransfer began with a narrow job: helping international students pay tuition without the 3–5% foreign-exchange markups banks charged (FinTech Magazine). The company rebranded to Flywire — Finovate dates the rebrand to 2011, FinTech Magazine to 2015 — and expanded from education into healthcare, travel and select B2B payments (Finovate; FinTech Magazine). By its May 2021 Nasdaq debut it counted 2,250 customers, including more than 1,900 educational institutions and over 80 healthcare systems, and had facilitated about $2.9 billion in payment volume in the first quarter of 2021 alone (Finovate; FinTech Magazine). The IPO sold 10.44 million shares at $24 — upsized from an 8.7-million-share plan in the $22–24 range — raising about $300 million at a roughly $3 billion market capitalization, after $323 million raised privately and unicorn status reached in February 2020 on a $120 million round (Finovate; FinTech Magazine). CEO Mike Massaro framed the opportunity as a “$12 trillion” market across the four industries, with clients already in 30 countries (Finovate). The healthcare push was reinforced by the acquisition of the healthcare payments technology platform Simplee (FinTech Magazine).
Hospitality becomes the growth engine
Flywire’s biggest strategic bet to date came in February 2025: the $330 million acquisition of Sertifi, a Chicago-based SaaS provider whose platform lets hospitality businesses sign contracts, exchange payment details and complete customer payments, integrated with catering and property-management systems (Built In Boston; Skift). Sertifi brought a client base spanning 20,000 unique hotel locations — including Marriott, Hilton and Hyatt brands plus luxury independents — and, in Massaro’s words, “a software solution in the early stages of its payments monetization journey,” which Flywire planned to scale internationally with its go-to-market teams (Built In Boston). The deal, funded with cash and debt, added a new category to Flywire’s travel business, whose clients had mostly been tour operators, destination management companies and hotels (Skift). Sertifi had also digitized hotels’ events workflows — simplifying event contracting and group bookings — and Flywire planned to scale that capability internationally with its go-to-market and partnership expertise (Built In Boston). At the time Flywire served about 4,500 clients globally across all its industries (Skift).
Open banking comes to North America
In August 2026 Flywire extended its partnership with Trustly to bring open-banking payments to the U.S. and Canada, letting payers authorize large domestic and cross-border payments directly from their bank accounts in their local currency — no re-entering account details, just existing online-banking credentials at checkout (PYMNTS). The expansion builds on what the companies describe as a nearly two-decade collaboration in Europe, applying open-banking infrastructure already scaled there to North America’s distinct regulatory landscape (PYMNTS). “Our clients tell us their payers want modern, digital payment experiences that eliminate friction,” said Kate Moran, Flywire’s vice president of global payments, framing the move as accuracy, fewer payment failures and real-time visibility for high-value bank transfers (PYMNTS).
What this profile does not claim
- It does not resolve the rebrand-year discrepancy: Finovate says peerTransfer became Flywire in 2011; FinTech Magazine says 2015. Both are reported above rather than silently reconciled.
- It does not pin the Simplee acquisition to a month; the fetched source’s “February this year” (2021) conflicts with an unfetched source’s February 2020.
- It does not state Q4 2024 results or the reported 10% workforce restructuring, which appeared only in snippet-level coverage that was not fetched in full.
- It does not claim the TenPay/Weixin Pay corridor for Chinese students or the 2026 luxury-traveler survey findings; those appeared only in snippets.
- No internal links were added: no fetched source established a direct, sourced relationship between Flywire and any existing FactsLedger profile (Sertifi and Trustly have no profiles).

What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- The peerTransfer-to-Flywire rebrand year is inconsistent across fetched sources — Finovate says 2011, FinTech Magazine says 2015. Both are stated with the discrepancy flagged rather than silently resolved.
- The Simplee acquisition month is stated without a month — FinTech Magazine (pre-IPO, 2021) says 'February this year' (i.e., Feb 2021) while an unfetched Forbes mirror said Feb 2020.
- Q4 2024 results and a reported 10% workforce restructuring appeared only in snippet-level coverage and were not fetched in full; they are not stated.
- The TenPay/Weixin Pay corridor for Chinese students and Flywire's 2026 luxury-traveler survey appeared only in snippet-level coverage; not stated.
