Significant Risks and Uncertainties The Company is subject to those risks common in the technology industry and also those risks common to early stage companies including, but not limited to, the possibility of not being able to successfully develop or market its products, technological obsolescence, competition, dependence on key personnel and key external alliances, the successful protection of its proprietary technologies, compliance with government regulations, and the possibility of not being able to obtain additional financing when needed. Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities, and trade receivables. The Company maintains the majority of its cash and cash equivalents in accounts with large financial institutions. At times, balances in these accounts may exceed federally insured limits; however, to date, the Company has not incurred any losses on its deposits of cash and cash equivalents and believes the exposure to risk of loss is not material. Risks associated with the Company’s marketable securities is mitigated by investing in investment-grade rated securities when purchased. The Company’s accounts receivable are derived from customers located in the United States, APAC, and Europe. The Company mitigates its credit risks by performing ongoing credit evaluations of its customers’ financial conditions and requires customer advance payments in certain circumstances. As of September 30, 2023, three customers accounted for 26%, 25% and 12% of the accounts receivable, respectively. As of December 31, 2022, one customer accounted for 66% of accounts receivable. As of September 30, 2023, two vendors accounted for 21% and 10% of the accounts payable, respectively. As of December 31, 2022, two vendors accounted for 10% each of the accounts payable.
