How it happened

System1 runs a 'responsive acquisition marketing platform' and owns properties like the privacy search engine Startpage; it went public in January 2022 via a SPAC merger at a $1.4B enterprise value. Apple and Google privacy changes and a softening ad market hammered its search-arbitrage business β€” 2023 revenue fell 51% β€” while heavy debt weighed on the balance sheet, collapsing the stock and forcing a 1-for-10 reverse split in 2025. Employees' Glassdoor reviews from the post-IPO years described a well-liked culture cooling after the listing, with repeated layoff rounds β€” some counting several a year as the share price fell β€” frequent strategy shifts, and editorial staff replaced by AI.
