Notable findings and disputes

strong corroboration Boost Oxygen is operating; Kevin O’Leary’s investment is directly corroborated, but contemporaneous sources conflict over the final equity terms. [ BO2, BO3, BO6, BO7 ]
verified fact O’Leary’s own 2020 interview is direct post-show evidence that an investment occurred. [ BO6 ]
unresolved The 6.25% televised figure versus the founder-reported 5% may reflect renegotiated closing terms, but that explanation remains inference without executed documents. [ BO4, BO5 ]
verified fact Current company copy reduces the transaction to a 'million-dollar deal' and omits dated loan/equity detail; without an archived version of that same page, this shows narrative simplification but not a proven edit. [ BO2, BO4, BO5 ]

What we could not verify

Executed financing documents and exact final interest/equity terms.
Connecticut entity number and current home-state standing.
Same-page archived versions proving whether current deal wording was edited.
