The consideration was 3.3 million Enea Data shares plus SEK 1.7 million in cash; EE Times valued the deal at about $4.75 million at the time. Enea’s aim was to bring a proven database partner in-house and pair its technology with the OSE real-time operating system for communications and other embedded systems.
What Enea bought, and what it paid
The March 27, 2001 announcement said Stockholm-based Enea Data acquired all shares in Polyhedra plc, a UK company headquartered in Cranfield. Polyhedra was to operate as an Enea Data subsidiary.
| Deal detail | Reported figure |
|---|---|
| Shares acquired | All Polyhedra shares |
| Share consideration | 3.3 million Enea Data shares |
| Cash consideration | SEK 1.7 million |
| Contemporary estimated value | About $4.75 million, as reported by EE Times on March 29, 2001; this was not an all-cash price |
| Polyhedra 2000 sales | About £1.5 million, or approximately $2.2 million at the time, according to Enea |
| Polyhedra 2000 profit | About £140,000, or approximately $210,000 at the time, according to Enea |
Enea’s figures imply a profit margin of roughly 9.3% for Polyhedra in 2000. That operating result is separate from the acquisition consideration: the transaction also bought database technology, engineering expertise, and an established relationship with customers and projects.
Why an embedded database mattered
Polyhedra was not positioned as a general-purpose enterprise database. It was a SQL-compatible database designed for products such as communications equipment, where developers needed data management in a constrained device and could not treat downtime or delayed updates as routine.

#1 Best Overall
Contemporary coverage described a compact, fault-tolerant system with standby-server recovery: if the primary server failed, a standby could take over. Later Enea descriptions help illustrate the product’s subsequent capabilities, but should not be read as a specification of the 2001 release. In later product materials, Enea described in-memory relational operation, journaling, replication and active queries—updates that notify applications when relevant data changes, rather than requiring constant polling. See Enea’s Polyhedra 8.2 announcement and its account of the Merlin helicopter program.
Those features addressed a specific engineering problem: combine responsive data handling with mechanisms for recovery when a component fails. The value to an equipment maker was not simply database speed, but the possibility of shipping a reliable data layer as part of an embedded product.

The partnership preceded the acquisition
Enea OSE Systems and Polyhedra had worked together since 1998, particularly on Ericsson CDMA infrastructure. Enea’s announcement said ownership would let it use Polyhedra’s technology more effectively and offer a more complete high-availability solution. The deal therefore formalized a relationship already tested in customer work, rather than starting from an unproven supplier arrangement.
Strategically, it was a vertical-integration move. Enea could offer its OSE real-time operating system alongside a database layer, while gaining more direct control over a component that mattered to its communications-platform ambitions. The trade-off was that closer alignment with OSE could create a risk of neglecting Polyhedra customers using other operating systems; preserving cross-platform support would be important to the database’s value beyond Enea’s own stack.

Integration and people: plans, not all confirmed outcomes
Enea said Polyhedra’s technology would be integrated with OSE. The announcement establishes that as an intention, not the exact timing or extent of the integration. Later Enea material documents Polyhedra in other operating-system and hardware contexts, including the Merlin system, which ran on Freescale PowerPC hardware with Green Hills’ INTEGRITY RTOS.
Polyhedra had about 20 employees across Europe and the United States. Enea intended to retain them. Founder and president Dave Stoneham was expected to leave full-time management but remain with the company, while Chris Ball, who had joined the previous year, was expected to lead the database group within Enea. EE Times also reported that the UK sales offices were likely to close; that was a forecast, not confirmation that they did close.
A later example of the product’s market
In 2007, Lockheed Martin UK selected Enea database management systems for a tactical mission-computer system in the Merlin helicopter program. Enea’s announcement described an embedded defense application, illustrating the kind of reliability-sensitive use for which Polyhedra was marketed. This later selection shows the product’s market positioning; it is not evidence that the Merlin work prompted the 2001 acquisition.

The 2001 transaction added a specialized embedded database to Enea’s software portfolio and brought a longstanding partner under its ownership. Its strategic logic was to strengthen Enea’s ability to supply a broader platform for communications equipment, combining real-time operating-system capabilities with data management and fault-recovery features. The available contemporary accounts establish the plan and rationale, but do not by themselves establish every later organizational change or the precise course of technical integration.
