DataStax snaps up Aurelius and its Titan team to build new graph database
Summary:The prize in DataStax's acquisition of open-source firm Aurelius is not the Titan database but rather engineering expertise, which will be used in developing a new graph database.
Context & Ripple Effects
In 2015 DataStax was a Cassandra-centric NoSQL vendor valued around $830M, and the Aurelius deal is an expertise acquisition: the prize is the Titan engineering team, not the database code itself, aimed at building a new graph product alongside Cassandra.
The move aged well enough that DataStax later raised $115M at double that price in its $1.6B round, and the company eventually drew an acquisition plan from IBM for its cloud database platform — making this early graph bet part of the asset base IBM is buying.
First-order effects
- Aurelius' Titan engineers join DataStax, shifting the open-source project's stewardship to a commercial vendor whose roadmap now includes a proprietary successor graph database.
Second-order effects
- Dedicated graph vendors such as TigerGraph — which later pulled in $105M from Tiger Global — gain a competitor that can bundle graph analytics with an installed Cassandra operational-data customer base.
Third-order effects
- The deal follows the playbook Microsoft used when it bought Citus Data's PostgreSQL team: infrastructure vendors absorbing small open-source teams to extend platform reach instead of building in-house, a pattern that culminated here with IBM moving to acquire DataStax outright.
The trend: Database platforms are assembling their portfolios through acqui-hires of open-source teams, with graph emerging as the next capability layer bolted onto operational data stores.
