## Questions

### Is Fidessa Asset Management an asset manager or a technology vendor?

Fidessa Asset Management is a product line within ION Group's equity trading technology division, not a traditional asset manager. The 'Asset Management' label on the ION website refers to the LatentZero suite of buy-side order management and compliance tools, distinct from the Fidessa sell-side equities platform. The firm licenses and hosts trading infrastructure; it does not manage investor capital or operate funds. No AUM is disclosed because the model is SaaS and software licensing, not balance-sheet investing.

### Who runs Fidessa's operations and product direction?

Fidessa operates as a division of ION Group, which is controlled by founder and CEO Andrea Pignataro. Day-to-day product management and engineering report into ION Markets leadership. The firm does not publish separate management bios for Fidessa. Client relationship references on its website point to individual buy-side and sell-side contacts at named institutions like Peel Hunt and Marex, rather than in-house portfolio managers.

### How does Fidessa connect to the private markets?

Fidessa connects to the London Stock Exchange's Private Securities Market. Through that integration, Registered Auction Agents on the Fidessa network can access private company auctions. Tom Simmons, Director of Private Markets Development at LSEG, has stated that Fidessa customers can broaden participation in private company share auctions via the platform. This is an extension of Fidessa's listed equities workflow, not a standalone private-markets trading desk.

### What investment stages or asset classes does Fidessa Asset Management target?

The LatentZero 'Asset Management' product suite targets buy-side institutions managing public-market portfolios: equities, fixed income, cleared derivatives, foreign exchange, and secured funding. Fidessa's sell-side equities platform covers listed equities, equity swaps, and ETFs. Neither product suite targets venture capital, private equity, or direct balance-sheet investing in companies. The firm does not deploy capital; it provides the execution and order management technology that other asset managers use.

### Does Fidessa participate in fund commitments or direct deals?

No. Fidessa does not commit capital to funds or make direct investments in companies. Its business model is entirely fee-based — charging sell-side and buy-side clients for access to trading and order management software. The firm's reference to 'Asset Management' on its website describes the LatentZero OMS and compliance tools sold to traditional asset managers, not a capital-allocating entity.
