Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Zeta Acquisition Corp. I (the "Company") was incorporated under the laws of the State of Delaware on November 16, 2007. The Company was organized as a vehicle to investigate and, if such investigation warrants, acquire a target company or business seeking the perceived advantages of being a publicly held corporation. The Company's principal business objective for the next twelve (12) months and beyond will be to achieve long-term growth potential through a combination with a business. The Company will not restrict its potential candidate target companies to any specific business, industry or geographical location and, thus, may acquire any type of business.
Liquidity and Going Concern	Liquidity and Going Concern At September 30, 2019, our cash position and history of losses required management to asses our ability to continue operating as a going concern, according to FASB Accounting Standards Update No. 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern ("ASU 2014-15"). Management evaluated the history and operational losses to have a material effect on our ability to continue as a going concern, unless we take actions to alleviate those conditions. Our primary sources of liquidity have been funds generated from our debt financings. Management believes that its existing cash, along with certain related parties' commitments to provide continued funding and capital resources, will be sufficient to fund the Company's operations for at least the next twelve (12) months.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.
Cash	Cash Cash consists of a bank checking account.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC Topic 740, Income Taxes, which requires the recognition of deferred tax liabilities and assets at currently enacted tax rates for the expected future tax consequences of events that have been included in the financial statements or tax returns. A valuation allowance is recognized to reduce the net deferred tax asset to an amount that is more likely than not to be realized.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company considers the carrying value of cash, accounts payable, accrued expenses, accrued interest, and notes payable to stockholders to approximate fair value due to their short maturities
Net Loss Per Share	Net Loss Per Share Basic loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. The Company currently has no dilutive securities and as such, basic and diluted loss per share are the same for all periods presented.
Interim Financial Statements	Interim Financial Statements The unaudited interim financial information included in this report reflects normal recurring adjustments that management believes are necessary for a fair statement of the results of operations, financial position, and cash flows for the periods presented. This interim information should be read in conjunction with the financial statements and accompanying notes contained in the Company′s Form 10-K filed March 28, 2019. The results of operations for the nine months ended September 30, 2019 are not necessarily indicative of the results to be expected for other interim periods or the full year.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect.
