AI Reasoning: Searches of Frontline’s site, news articles, Crunchbase, LinkedIn and public posts locate Brennan O’Donnell as a Partner at Frontline Ventures and list portfolio companies (Forethought, Airtable, Vibely, Mode Analytics), but I could not find dated investment announcements or transaction dates tied to Brennan that indicate his most recent investment. Without a verifiable date for his latest investment (e.g., press release, Crunchbase or portfolio update with date), I cannot determine recency. Therefore the appropriate classification is not-found.
