The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Reflects the 197,250 private units owned by Blueport Acquisition Corporation, the Issuer's sponsor (the "sponsor"). Each private unit consists of one Class A ordinary share, and one right to receive one-sixth (1/6th) of one Class A ordinary share upon the consummation of the Issuer's initial business combination. The private units were purchased at $10.00 per unit for an aggregate purchase price of $ 1,972,500. The sponsor is managed by its two principals, William Rosenstadt and Roy Jiang, and is legally and beneficially owned (i) 50% by William Rosenstadt and (ii) 50% by Roy Jiang. By virtue of their shared control of our sponsor, William Rosenstadt and Roy Jiang may be deemed to have beneficial ownership of the shares held directly by our sponsor. The address for the sponsor is 366 Madison Avenue, 3rd Floor New York, NY 10017. Mr. Rosenstadt disclaims any beneficial ownership of the shares held by the sponsor, except to the extent of his pecuniary interest therein. The rights convert automatically into Class A ordinary shares concurrently with or immediately following the consummation of the Issuer's initial business combination. If the business combination has not been consummated within the applicable time period specified in the Issuer's Amended and Restated Memorandum and Articles of Association, the rights shall expire and shall be worthless.
