| De-SPAC, Board Determination, Prospectus Summary [Text Block] | The SSAC Board’s Reasons for the Approval of the Business Combination The SSAC Board, in evaluating the Business Combination, consulted with SSAC’s management and technological, financial and legal advisors. In reaching its unanimous decision that the Business Combination Agreement and the transactions contemplated by the Business Combination Agreement are advisable and in the best interests of SSAC and its shareholders, and to recommend that the SSAC Shareholders adopt the Business Combination Agreement and approve the Business Combination, the SSAC Board considered a range of factors, including, but not limited to, the factors discussed below. In light of the number and wide variety of factors considered in connection with its evaluation of the proposed combination, the SSAC Board did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination and supporting its decision. The SSAC Board contemplated its decision in the context of all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors. This explanation of the SSAC Board’s reasons for approving the combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section titled “ Cautionary Note Regarding Forward-Looking Statements |

| De-SPAC, Report Concerning Approval of De-SPAC Transaction, Received, Prospectus Summary [Text Block] | The Domestication Proposal SSAC is asking the holders of the Class B Ordinary Shares to approve by special resolution the Domestication Proposal. The consummation of the Domestication is a condition to Closing pursuant to the terms of the Business Combination Agreement. The Domestication Proposal, if approved, will authorize that SSAC be transferred by way of continuation to Delaware pursuant to article 49 of the Existing Governing Documents, Part XII of the Companies Act (As Revised) of the Cayman Islands and Section 388 of the General Corporation Law of the State of Delaware and, immediately upon being de-registered in the Cayman Islands, SSAC be continued and domesticated as a corporation under the laws of the State of Delaware. Accordingly, while SSAC is currently incorporated as an exempted company under the Cayman Islands Companies Act, upon the Domestication, SSAC will be governed by the DGCL. For more information about the Domestication Proposal, we encourage shareholders to carefully consider the information set forth below under “ Proposal No. 2-The Domestication Proposal |

| De-SPAC, Actual or Potential Material Conflict of Interest, Prospectus Summary [Text Block] | In particular, when you consider the recommendation regarding these proposals by the board of directors of SSAC, you should keep in mind that the Sponsor and SSAC’s directors and officers have interests in the Business Combination that are different from or in addition to, or may conflict with, your interests as a shareholder. For instance, the Sponsor, SSAC’s officers and directors and/or their affiliates will benefit from the completion of a business combination and may be incentivized to complete an acquisition of a less favorable target company or on terms less favorable to shareholders rather than liquidating SSAC. See “ Proposal No. 1-The Business Combination Proposal-Interests of Certain Persons in the Business Combination” and “ Proposal No. 1-The Business Combination Proposal-Conflicts of Interest and Waiver of Corporate Opportunity Doctrine” for a further discussion of these considerations. |

| De-SPAC, Rights of Security Holders to Redeem Outstanding Securities [Text Block] | Redemption Rights Holders of Class A Ordinary Shares may seek to redeem their shares for cash, regardless of whether they vote for or against, or whether they abstain from voting on, the Business Combination Proposal.

If a holder properly seeks redemption as described in this proxy statement/prospectus and the Business Combination is consummated, SSAC will redeem these shares prior to the Domestication for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own these shares following the Business Combination. Additional terms and conditions apply.
