The systems that cannot fail.

RhinoSource is a Silicon Valley consultancy and long-time Oracle and DataStax partner. We design, build and optimize the high-performance data platforms behind IoT, mobile and web-scale systems — for Fortune 500 enterprises, government agencies, and the startups that intend to become them.

How we got here

The through-line is Oracle. Dave Herrington was one of Oracle Corporation's original 12 Oracle Applications consultants — among the people who launched its applications business — and went on to found and lead DARC Corporation for nearly two decades, North America's go-to Oracle E-Business Suite implementation partner.

Then the data got bigger than one machine. RhinoSource was founded in 2012 as an Oracle and DataStax partner, and the DataStax years became the firm's signature: the consultancy DataStax brings in when a Cassandra cluster has to perform under real pressure — peak holiday load at eBay, statewide reporting at the California DOJ, mail tracking for the U.S. Postal Service.

Today the frontier has moved again, to Snowflake data lakes and the generative and agentic AI built on top of them. The work is the same work it always was: make the data trustworthy, make the platform hold, and make it keep holding when the load arrives.

Four practices

  • Cassandra & DataStax

    Your cluster has to perform under real pressure — latency, migrations, go-live, or an SLA you cannot miss.

  • Snowflake & AI

    Your data is scattered across SQL and SaaS, and you want it governed, unified, and actually ready for AI.

  • AWS for Startups

    You're pre- or early-revenue and need founding cloud architecture that won't have to be ripped out at Series B.

  • Oracle

    You run mission-critical Oracle at IoT scale and it cannot go down — through upgrades, failovers or growth.

Service first

RhinoSource leads with service. In addition to keeping our customers' mission-critical systems running, we build our own products — gr8ful.ai, Tank Patrol, WorkCenter — and they keep us honest at the frontier. What you get first is an architect who has already shipped the thing you are about to build.
