The problem: marketing agencies share live Data Bloo dashboards with clients, but when a client wants to flag something ('this conversion number looks off,' 'can we add last month?'), the feedback loop collapses into emailed screenshots, Slack threads, and Loom recordings. The agency has to reverse-engineer which chart the client meant, and context gets lost across report versions. The product, Data Bloo HTML Annotation Layer, is a plugin that renders an interactive markup overlay on top of live Data Bloo report elements. A non-technical stakeholder clicks any chart, table, or metric tile and pins a comment directly to that DOM element. The agency sees threaded, element-anchored feedback in context, with no screenshots. The solution works because comments are bound to the underlying report element rather than a pixel location, so they survive layout and data refreshes. MVP: an embeddable overlay script that attaches comment pins to Data Bloo report elements, a comment thread panel, email notifications to the agency, and simple resolve/reopen status. Revenue: per-seat or per-workspace SaaS billed to the agency, since the agency owns the client relationship and pays for white-labeled sharing. GTM: distribute through the Data Bloo ecosystem and plugin listing, then direct outreach to agencies already sharing live Data Bloo dashboards. Growth loops: every client invited to annotate a report is exposed to the product and becomes a candidate buyer when they switch agencies or start their own; each resolved thread demonstrates faster turnaround that agencies cite to win retainers.
