Navigator is a quantitative liquidity risk projection tool that is one of the key components of Addepar's multi-product ecosystem. Brought into the Addepar family as part of an acquisition in 2021, Addepar has continued to double down on investing in this critical product, as we've scaled well beyond the multi-million ARR goal first set for this product line.
