Convertible promissory note, description		Extended the maturity date of our term loan and revolver loan to August 16, 2020 through the Fifth Amendment to the Loan and Security Agreement. In conjunction with the extension of the maturity date of our term loan, we agreed that the interest rate would increase from 8.0% per annum to 10.0% per annum effective July 1, 2019.			We used proceeds from our common stock offering to repay Slipstream $1,283, inclusive of $125 of accrued interest, to reduce borrowings under the Loan and Security Agreement to an aggregate of $4,264, comprised of $3,000 term loan, $1,000 revolving loan and $264 secured disbursed escrow promissory note. The consolidated balance sheet includes $27 of accrued interest as of December 31, 2018 representing one month's interest at 8.0% on the $4,000 outstanding balance.	The conversion was contingent upon (i) the conversion of the Company's Series A Preferred Stock, and (ii) the successful completion of a Public Offering of at least $10,000, each of which were successfully completed on November 19, 2018. In exchange for participation in the Public Offering, subject to a minimum participation requirement as agreed between the underwriters and the Company, and Slipstream's execution of a lock-up agreement, Slipstream received, as a one-time incentive, additional common stock and warrants in such number that decreased the effective conversion price of the convertible notes to 70% of the lowest of those scenarios outlined above.

Allure Global Solutions, Inc. [Member] | Stock Purchase Agreement [Member]
Short-term Debt [Line Items]
Accounts payable to seller for outsourced services									$ 2,204
Long term seller note payable									$ 2,303

[1] Represents a note payable due from Allure to Seller, under a pre-existing Seller Note which was amended and restated for this amount through the Stock Purchase Agreement. At the closing date, the estimated net working capital deficit of Allure was $801 in excess of the target net working capital as defined in the stock purchase agreement. As of the acquisition date, Allure also had accounts payable to Seller for outsourced services of $2,204. We agreed with the Seller to settle the estimated net working capital deficit through a reduction in the accounts payable to Seller as of the acquisition date and to further amend the Seller Note to include the remaining $1,403 accounts payable due from Allure to Seller. The Seller Note thereby increased from $900 per the Stock Purchase Agreement to $2,303 at the opening balance sheet. That debt is represented by our issuance to the Seller of a promissory note accruing interest at 3.5% per annum. The promissory note required us to make quarterly payments of interest through February 19, 2020, on which date the promissory note matured and all remaining amounts owing thereunder were due. See Note 10 Commitments and Contingencies in the consolidated financial statements for further discussion of this note, which is now past due.
