Forward Looking Statements

The press release referred to herein includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements also include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, projections of market opportunity and expectations, the estimated implied enterprise value of the combined entity (the “Combined Company”) pursuant to the transactions contemplated by the Business Combination Agreement (the “Proposed Transaction”), the Company’s ability to scale and grow its business, the advantages and expected growth of the Combined Company, the Combined Company’s ability to source and retain talent, the cash position of the Combined Company following closing of the Proposed Transaction, the SPAC’s and the Company’s ability to consummate the Proposed Transaction, and expectations related to the terms and timing of the Proposed Transaction, as applicable. These statements are based on various assumptions, whether or not identified in the press release referred to herein, and on the current expectations of the SPAC’s and the Company’s management and are not predictions of actual performance.

These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. Although each of the SPAC and the Company believes that it has a reasonable basis for each forward-looking statement contained in the press release referred to herein, each of the SPAC and the Company cautions you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, there will be risks and uncertainties described in the proxy statement/prospectus included in the registration statement relating to the Proposed Transaction, which is expected to be filed by the Combined Company with the Securities and Exchange Commission (the “SEC”) and other documents filed by the Combined Company or the SPAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Neither the SPAC nor the Company can assure you that the forward-looking statements in the press release referred to herein will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the ability to complete the Proposed Transaction due to the failure to obtain approval from the SPAC’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to

the termination of the Business Combination Agreement, the ability to recognize the anticipated benefits of the Proposed Transaction, the amount of redemption requests made by the SPAC’s public shareholders, costs related to the Proposed Transaction, the impact of the global COVID-19 pandemic, the risk that the Proposed Transaction disrupts current plans and operations as a result of the announcement and consummation of the Proposed Transaction, the outcome of any potential litigation, government or regulatory proceedings, and other risks and uncertainties, including those to be included under the heading “Risk Factors” in the registration statement to be filed by the Combined Company with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2022 of the SPAC and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. There may be additional risks that neither the SPAC nor the Company presently know or that the SPAC and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In light of the significant uncertainties in these forward-looking statements, nothing in the press release referred to herein should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. The forward-looking statements in the press release referred to herein represent the views of the SPAC and the Company as of the date of the press releases. Subsequent events and developments may cause those views to change. However, while the SPAC and the Company may update these forward-looking statements in the future, there is no current intention to do so, except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing the views of the SPAC or the Company as of any date subsequent to the date of the press release referred to herein. Except as may be required by law, neither the SPAC nor the Company undertakes any duty to update these forward-looking statements.

Exhibit 99.1

Cheche Technology Releases its Auto Insurance 2.0 EV Upgrade Solution Featuring the AI-enabled Sky Dome Risk Management Platform

Beijing, China – June 1, 2023 – Cheche Technology Inc. (“Cheche Technology” or the “Company”), China’s leading auto insurance technology platform, announced the release of its EV 2.0 Upgrade Solution featuring the Sky Dome Risk Management Platform. This comprehensive business intelligence platform synthesizes various categories and levels of data, augmented by machine learning, to drive superior capabilities in underwriting, pricing, claims management, and group fraud detections.

After more than two years of research and development, Cheche’s 2.0 Upgrade Solution is connected to more than ten leading insurance companies, including the People’s Insurance Company of China, Ping An Insurance Group, and China Pacific Insurance. It currently serves more than ten of the top NEV companies, including NIO, Li Auto, Xpeng, and JIDU. The platform spans software-as-a-service (SaaS) systems, insurance company application programming interface (“API”) integrated management, digital operations, and value-added services.

Five advantages set this technology apart from any competing offering:

Sky Dome Risk Management Platform Leveraging AI and Machine Learning

The Upgrade’s biggest highlight is the company’s enhanced ability to identify and manage risk. The Sky Dome insurance anti-fraud model combines static factors and dynamic variables such as a risk-rule engine and a personal injury database to identify anti-fraud behavior during claims settlements. Variables are screened through different algorithms and regression analyses. The product is easy to operate, easy to deploy, and scalable.

“The Sky Dome integrated solution is revolutionizing the underwriting process, providing a streamlined approach to risk mitigation and crafting policies more appropriately tailored to consumer needs, maximizing the value and satisfaction when purchasing a new vehicle,” said Lei Zhang, CEO of Cheche Technology. “Optimized pricing and superior fraud detection not only drives efficiencies that boost the carriers’ bottom line, but ultimately reduces the total cost of vehicle ownership.”

While often difficult to detect initially, the Chinese auto industry continues to be plagued by claims fraud. Accounting for local risk characteristics in different regions, the risk control model accurately identifies risks, helping insurance companies optimize pricing and loss ratios. The accuracy of a risk management model is highly dependent on the data quality it synthesizes, such as loss history and the driver’s personal information.

“While the Comprehensive Reform of Auto Insurance has led to greater pricing flexibility, companies don’t always have effective guidelines to enforce real-time precision pricing strategies. Sky Dome can derive price recommendations by region, enabling insurance carriers to manage pricing strategies better and launch promotions more effectively,” continued Lei Zhang. “We are very encouraged by the initial reception to this innovative solution by many of China’s largest insurers. We plan to continue ramping up investments in artificial intelligence and big data technology to drive the digitalization of insurance products, making them more efficient and accessible to consumers.”

An insurance company relying strictly on its own resources is unlikely to deliver the most effective claims risk detection, but with the Auto Insurance Risk Management Platform, a company can accurately determine a risk score after predicting the exposure of the personal passenger vehicle and its potential economic loss. Once driver, vehicle, and accident location data are processed, the platform can detect fraudulent group events in real-time, helping to correctly calibrate the accuracy of policy pricing, underwriting management, and claims management.

Cheche Technology announced on January 30, 2023, that it had entered into a definitive business combination agreement with Prime Impact Acquisition I (“Prime Impact”) (NYSE: PIAI), a publicly traded special purpose acquisition company, that will result in Cheche Technology becoming a publicly listed company. Upon closing, the combined company will be listed on Nasdaq under the new ticker symbol CCG.
