## Profile
43Twenty is the consultancy-plus-publication hybrid that founder Kirby Grines built around a single editorial thesis: that engagement, frequency, and session length — not raw subscriber counts — are the actual drivers of streaming-platform value. The agency works with streaming, media, entertainment, and technology companies on positioning, growth, and content marketing; the publication side, The Streaming Wars, expanded from newsletter to a full content site in 2024 and now functions as the editorial credibility layer behind the consulting business.

The pre-history matters editorially. Grines co-founded Float Left in 2009, building some of the first Roku apps when Roku had no category — that operator-side CTV-OS background gives 43Twenty's analysis standing on the home-screen and platform-architecture layer that pure marketing-strategy consultancies don't bring. The Streaming Wars site applies that lens across the recurring beats Grines tracks publicly: Roku's CTV-OS share (28% of U.S. connected-TV platforms per Parks Associates data Grines cited April 30, 2026), Samsung's parallel position (23%), Netflix's "attention per user" framing at 325M subscribers, and the broader Meta + YouTube engagement-products thesis on session length and habit formation.

The agency name is a deliberate signal — 4,320 is the vertical pixel resolution of 8K video — and the positioning consistently aligns the consulting practice with the highest-resolution version of streaming-industry analysis. 43Twenty remains privately held; client lists, revenue, and headcount are not publicly disclosed.
