What Xpace does

Xpace LLC is a privately held US software company headquartered in Brookhaven that develops and licenses Aeolus, a proprietary high-performance database engine purpose-built for very large, largely immutable archival data stores. The technology automatically indexes all data without requiring upfront index-type design decisions, applies a custom compression framework that materially shrinks storage versus conventional RDBMS engines, and performs searches and sorts in seconds on commodity hardware. The roots of the engine lie in the InPress database originally built by founder Paul Sepe for Archi-Tech Systems' pharmaceutical marketing data product DART, and Aeolus emerged as a standalone commercial vehicle for the technology in or around 2015.

The product addresses data-intensive enterprises whose existing data warehouses have become 'data tombs' — slow to query, expensive to store, and difficult to redistribute. Documented use cases span brokerage and financial services firms needing regulatory-grade retrieval from tape-scale archives, market research firms handling billions of records, navigation and GIS vendors embedding compressed geographic datasets on constrained devices, and large aircraft operators processing telemetry at tens of billions of rows. Publicly cited benchmarks compare the engine head-to-head with Oracle on an NYSE TAQ dataset, claiming order-of-magnitude gains in speed and storage efficiency on commodity hardware.

Xpace monetizes through direct enterprise sales, relying on demonstration databases and benchmark comparisons rather than disclosed pricing, and offers a Java API for application integration. The operating team is small — comprising President Paul Sepe, SVP Sales Wolfgang Ruth, VP Marketing Diane Lore, consultant Yoshitaka Baba, and co-founder Paul Gray (who also leads Archi-Tech Systems). The company has not raised external capital, has no disclosed revenue, and operates as a tightly held, founder-controlled business.

Core offering

Xpace develops and licenses the Aeolus database engine, a high-performance, fully indexed and compressed data store designed for very large archival datasets. The product automatically builds tens to hundreds of thousands of indexes without manual design decisions, delivers extreme storage compression versus conventional DBMS, and supports fast search, sort, and custom ETL workloads on commodity hardware. It is sold primarily to enterprises and institutions managing terabyte-scale historical data such as brokerage firms, market research companies, navigation software vendors, and large aircraft fleet operators.

Product overview

Xpace offers an integrated set of tools optimized to manage large, archival data stores quickly, with greater flexibility and less expense using industry standards on commodity hardware. The core product is Aeolus, a compressed data store that replaces conventional database management systems and OLAP solutions. Aeolus provides dramatically faster build and retrieval times compared to traditional systems like Oracle, with automatic indexing that eliminates the need for manual index type selection (Bitmap vs. B-tree decisions). The technology traces its roots to InPress, the database engine developed by Paul Sepe for Archi-Tech's pharmaceutical data management products. Xpace is designed for databases that don't change much but can handle additions efficiently.

Partnerships

One partnership is on record.

• Archi-Tech SystemscoreStrategic or Co-development PartnerArchi-Tech Systems is a provider of software to manage pharmaceutical marketing research data. They contracted Paul Sepe to write a database back-end (InPress engine) for larger datasets. Archi-Tech's products including DART (now in fourth generation) use this technology. Paul Gray, President/CEO and founder of Archi-Tech, is a co-founder of Xpace. The partnership has resulted in deep collaboration spanning almost two decades.

Recent moves5 records

Expansion highlights4 records

Direct peers

• Kx Systems (kdb+): Kdb+ is a high-performance columnar database used heavily for financial market data archival and tick analytics — the same primary use case Xpace targets (brokerage TAQ archives). Both compete on speed, compression, and time-series query performance for read-heavy financial workloads.
• InterSystems (IRIS): InterSystems IRIS is a high-performance multi-model database emphasizing fast access to large operational and analytical datasets, with a comparable 'faster, leaner than incumbents' positioning. It targets enterprise data-intensive verticals similar to Xpace's financial, pharma, and healthcare segments.
• Actian (Ingres/Vector): Actian's Ingres and Vector databases are long-standing high-performance OLTP/analytical engines that compete in similar archival and high-throughput niches. Like Xpace, they position against Oracle on cost and performance for read-heavy enterprise workloads.
• McObject (eXtremeDB): eXtremeDB is an embedded, high-performance database designed for edge/embedded systems with extreme speed and small footprint — the same niche Xpace serves in its navigation/PDA/embedded cases. Both target developers needing fast indexed access on constrained devices.
• FairCom (c-treeACE): c-treeACE is an embedded and server database with multi-model support, used in industries needing fast indexed access to large operational datasets. Its embedded footprint and performance emphasis overlap directly with Xpace's Aeolus positioning.

Emerging players

• ClickHouse (Yandex): ClickHouse is an open-source columnar OLAP database known for sub-second queries on billions of rows — directly comparable to Xpace's TAQ benchmark claims. It has rapidly captured the analytical/archival workloads that Xpace targets, with stronger cloud and ecosystem support.
• Aerospike: Aerospike is a high-performance real-time NoSQL database with strong indexing and sub-millisecond reads on large datasets. It overlaps with Xpace on indexed, fast, large-dataset workloads, especially in financial services, ad-tech, and telemetry use cases.

Broad incumbents

• Vertica (OpenText): Vertica is a mature columnar analytical database used for large-scale data warehousing and archival analytics, with overlapping use cases in financial services and market research — the same verticals Xpace serves. Both emphasize compression and fast queries on large fact tables.
• Snowflake: Snowflake is the dominant cloud data platform for analytical/archival workloads, offering elastic compute, managed services, and broad SQL compatibility. It competes indirectly with Xpace for large analytical data-store budgets, especially where buyers want cloud-native managed services over on-prem engines.
• Databricks: Databricks provides a lakehouse platform combining data warehousing, ETL, and AI/ML on large datasets. It competes for the same enterprise analytical/archival budgets Xpace targets and has become a default for large-volume, query-intensive workloads in finance and life sciences.
