## Questions

### Who makes investment decisions at Reaction Fund?

Reaction Fund has not publicly named any investment principals, managing directors, or decision-makers. Its leadership structure is entirely opaque as of mid-2026, with no team members listed on any public platform or regulatory filing. The firm's website and social media presence do not identify individuals.

### Does Reaction Fund disclose its assets under management or deployment track record?

No. AUM, deployment figures, portfolio companies, and historical returns are all undisclosed. The firm's lack of public transparency makes it impossible to verify its scale or track record through independent sources. This level of opacity is unusual for an institutionally marketed fund.

### What regulatory or compliance disclosures has Reaction Fund made?

No SEC Form ADV, UK FCA registration, or equivalent regulatory filings are publicly associated with Reaction Fund. The firm does not appear on major allocator databases and has not sought publicity via industry conferences or media coverage, contributing to its low institutional profile.

### Are there any verifiable portfolio companies or exit track records for Reaction Fund?

Not from public sources. No named portfolio companies, exits, or co-investment partners are attributable to Reaction Fund through press releases, news articles, or company announcements. The firm's investment activities remain entirely outside public visibility.
