+Added: Going Concern:
+Added: As of March 31, 2025, our cash and cash equivalents were approximately $ 961 compared to $ 1,417 as of December 31, 2024.
+Added: Our working capital was $ 13,537 as of March 31, 2025.

+Added: The decrease in cash is mainly due to a decrease in cash collected from receivables.
+Added: These and other conditions raise substantial doubt about continuing as a going concern.
+Added: We will need to complete one or more strategic transactions or raise additional working capital to continue our normal and planned operations.
+Added: We will need to generate and sustain significant revenue levels in future periods to become profitable, and, even if we do, we may not be able to maintain or increase our level of profitability.
+Added: In addition, as a public company, we will incur accounting, legal and other expenses.
+Added: These expenditures will make it necessary for us to continue to raise additional working capital.
+Added: Our efforts to grow our business may be costlier than we expect, and we may not be able to generate sufficient revenue to offset our increased operating expenses.
+Added: We may incur significant losses in the future for a number of reasons, including unforeseen expenses, difficulties, complications and delays and other unknown events.
+Added: Accordingly, substantial doubt exists about our ability to continue as a going concern and we cannot assure you that we will achieve sustainable operating profits as we continue to expand our business and otherwise implement our growth initiatives.
+Added: In February 2025, the Company raised $ 1,000 in a private placement transaction.
+Added: We may be unable to complete a strategic transaction within a reasonable timeframe, on attractive terms or at all, and market conditions, including the historical volatility in our common stock will likely limit our ability to raise capital on favorable terms, or at all, and the terms of any public or private offerings of debt or equity securities likely would be significantly dilutive to existing stockholders.
+Added: There is no set timetable for the overall process given the anticipated timelines for different strategic alternatives may vary, and there can be no assurance that this process will result in us pursuing a transaction or that any transaction, if pursued, will be completed on attractive terms or at all.
+Added: The Company’s ability to continue as a going concern is dependent on the outcome of these uncertainties.
+Added: As a result, management has concluded that substantial doubt exists about the Company’s ability to continue as a going concern for 12 months from the date these consolidated financial statements are issued.
+Added: The consolidated financial statements as of March 31, 2025 have been prepared under the assumption that the Company will continue as a going concern for the next 12 months after these financial statements are issued, and that contemplates the realization of assets and satisfaction of liabilities and commitments in the normal course of business.
+Added: These Consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

+Added: ASU 2024 - 03 does not alter the expense captions presented on the face of the income statement but enhances footnote disclosures to improve transparency.

+Added: The Company is in the process of evaluating the impact of ASU 2024 - 03 on its consolidated financial statements.
+Added: We expect adoption to necessitate modifications to our financial reporting processes and systems to capture and disclose the required disaggregated expense information in the footnotes.

+Added: We are reviewing our current expense classification practices and data collection capabilities to ensure compliance with the new requirements upon adoption.
