Patrick Barrett

Founder & CEO ECAL

Last Reviewed: September 19, 2026

Executive Summary

Patrick Barrett is the founder and chief executive of ECAL, a Melbourne-headquartered company that built a marketing channel out of a piece of software nobody thought of as one: the personal calendar. ECAL lets a rights holder — a football league, a race series, a broadcaster — push its fixtures, race times and programme schedules directly into a fan’s phone calendar, where they sit alongside dentist appointments and school pickups rather than competing for attention in an inbox or a social feed. The commercial insight is that a calendar entry is both permissioned and self-updating: when a match is rescheduled, the entry moves. Barrett has spent roughly two decades on the idea, building an early “e-diary” in 2004 and launching the ECAL platform in 2010, and has taken it to clients including the Premier League, Formula 1, the NBA, LaLiga, World Rugby and Disney+, across seven offices. ECAL has since been acquired by the Singapore-based venture group HyperKu, with Barrett continuing as CEO and joining the parent’s board.

Professional Journey

Barrett came to calendar software from sports marketing rather than from engineering, and the sequence explains the product. His early career, as set out by ECAL itself, ran through marketing roles at The British Horseracing Board — the body then governing British racing — and at Carlton Football Club, one of the foundation clubs of the Australian Football League. Both are organisations whose core commercial asset is a fixture list: a calendar of events that fans plan their lives around and that the organisation needs them to turn up to. He then went out on his own, founding Bat Parrot Marketing and athletes1 Racing before the ECAL idea took commercial form.

The first version of the idea arrived in 2004, when he built what the company describes as the first “e-diary”. It did not become a business then. What changed over the following six years was the infrastructure around it: smartphones put a synchronised calendar in every pocket, and calendar standards became something a brand could reliably write into rather than a desktop application quirk. ECAL launched in 2010 into that changed environment, and the pitch was no longer “here is a novel piece of software” but “here is a channel you already have permission to use”. The twelve-year gap between concept and category is the defining feature of his career rather than an aside — he had the idea well before the platform to run it on existed.

Commercial validation came in stages. Winning The Big Pitch in 2014 gave the company an early public profile and access to capital in an Australian market that was then thin on martech exits. Growth then came from the sports vertical, where the product’s logic was most obvious, and the client list Barrett assembled reads as a sequence of reference wins that each unlocked the next: a Premier League or a Formula 1 makes an NBA or a LaLiga a far easier conversation, because the rights-holder world is small and its executives compare notes. By his own account to trade press, the business ran at 30 to 50 per cent year-on-year growth for three consecutive years on the strength of that expansion, and it widened out of pure sport into entertainment and media with Disney+ and Fox Sports.

The most consequential structural decision of his tenure was selling the company. ECAL was acquired by HyperKu, a Singapore-based group, in a deal Barrett has said took twelve months to structure and which brought additional capital alongside the change of ownership. He framed the rationale as access rather than exit: the acquisition connected ECAL to HyperKu’s other portfolio companies, and the first product consequence was an integration with the payments company PayDock that let ECAL embed payment gateways and transact inside a calendar entry — turning a reminder into a point of sale. Barrett stayed on as chief executive and took a seat as a director of HyperKu Holdings, so he is now operating the business he founded while also sitting at the ownership level above it.

Around him he has built a board that is noticeably heavier on international media experience than a company of ECAL’s size usually attracts. Laura Poffenberger, a Big Shift Global partner formerly of Turner Sports, Yahoo! and CNN and the holder of several US patents in digital advertising, chairs it as a non-executive director. Glenn Lovett, chief executive of Dentsu Sports Analytics and previously at Nike and Nielsen, sits alongside her, as does HyperKu co-founder Remon Gazal. The advisory bench includes Walter de Oude, who founded Singlife and sold it to Aviva, and Mark Barnard, formerly chief commercial officer at Diageo. That composition is consistent with a company whose growth path runs through sports rights and global media buyers rather than through product-led self-service.
