Arun Sharma, founder of LadybugDB and Ladybug Memory, interviewed by Alexy Khrabrov at the Rows & Columns Summit. LadybugDB continues Kuzu, the embedded graph database developed at the University of Waterloo whose team was acquired by Apple: a well-regarded codebase with published research behind it and no community, which Sharma has spent eleven months building one around, with Ladybug Memory supporting the work and aimed at agentic memory. Before that, five years at Google and then Facebook, where he built a graph indexing system sitting beside the world's largest MySQL cluster, listening to its write-ahead log and built on RocksDB as its very first user, and in 2018 prototyped what today looks like Amazon DSQL.
