Temasek-Backed Vertex Japan Buys Into Digital Trading Cards Startup Heartbeats

Vertex Japan, an investment arm backed by Singapore's Temasek Holdings, has invested in Heartbeats, a startup that builds digital trading cards, according to a report from The Wall Street Journal.

The Journal described the deal as an exclusive, identifying Heartbeats as the recipient of the capital and Vertex Japan as the investing entity. The report did not disclose the size of the stake, the amount invested, or the valuation at which the transaction was struck.

The deal connects one of Asia's most established state-linked investment families to a young company operating in the digital collectibles market. Temasek, Singapore's state investment company, is the ultimate backer of the Vertex platform. Vertex Japan sits within that structure and deploys capital into Japanese and Japan-focused opportunities.

Heartbeats operates in digital trading cards, a segment that has drawn sustained investor attention as trading card culture has moved from physical cardboard to smartphone screens. The Journal's report did not detail Heartbeats' revenue, user base, or product roadmap.

The involvement of a Temasek-backed investor marks a notable signal for the category. Digital collectibles have seen waves of enthusiasm and retrenchment, and backing from a long-horizon institutional investor such as the Vertex network typically indicates diligence standards that early-stage consumer startups in the segment have not always attracted. The Journal did not say whether other investors participated in the round.

Neither Vertex Japan nor Heartbeats has publicly commented beyond the Journal's reporting, and no party named in the report has disputed its contents.

For Vertex, the investment extends a footprint in Japan's startup ecosystem, where the firm has backed companies across enterprise software, consumer technology, and financial services. The Journal's report positions Heartbeats as the latest addition to that portfolio.

For Heartbeats, the capital and the association with a Temasek-linked investor arrive at a moment when digital trading cards are competing for consumer attention against gaming, streaming, and social platforms. The startup now has an institutional shareholder with the balance-sheet patience to support multi-year growth, according to the deal as reported.

The transaction, as reported by The Wall Street Journal, suggests institutional capital continues to find room in the digital collectibles trade despite the sector's volatility. Whether Heartbeats converts that backing into durable consumer engagement will define the next chapter for both the startup and its newest investor.
