Item 3.	Source or Amount of Funds or Other Consideration.	
 
On September 30, 2014, the Insight Funds acquired 1,775,271 shares of the Issuer’s Series B Preferred Stock (the “Series B Preferred Stock”) and 5,788,898 shares of the Issuer’s  Common Stock (the “Common Stock”).  The Series B Preferred Stock was acquired for $8.3287 per share and the Common Stock was acquired for $6.6630 per share.
 
On September 23, 2015, the Issuer effected a 1-to-2.5 stock split of its outstanding capital stock, which resulted in the Reporting Persons owning 4,438,177 shares of Series B Preferred Stock and 14,472,245 shares of Common Stock.
 
On September 24, 2015, the Insight Funds acquired 3,659,465 shares of the Issuer’s Series C Preferred Stock (the “Series C Preferred Stock”) and 1,682,511 shares of Common Stock. The Series C Preferred Stock was acquired for $6.8316 per share and the Common Stock was acquired for $5.9435 per share.

On January 3, 2017, the Insight Funds acquired 488,722 shares of Common Stock.  The Common Stock was acquired for $7.00 per share.
 
On February 27, 2017, the Issuer effected a 2-to-1 reverse stock split of its outstanding capital stock. Also on February 27, 2017, the Issuer amended and restated its certificate of incorporation, in part implementing a dual class common stock structure where all existing shares of Common Stock converted to Class B Common Stock and the Issuer authorized a new class of Class A Common Stock. The Class A Common Stock is entitled to one vote per share and the Class B Common Stock is entitled to ten votes per share.
 
Immediately prior to the completion of the Issuer’s initial public offering on March 29, 2017 (the “IPO”), all outstanding shares of Series B Preferred Stock and Series C Preferred Stock were automatically converted into shares of the Issuer’s Class B Common Stock, resulting in the Insight Funds holding 12,870,545 shares of Class B Common Stock.  In addition, concurrently with the completion of the IPO, the Insight Funds purchased 675,000 shares of the Issuer’s Class A Common Stock for a price of $14.00 per share.
 
The Series B Preferred Stock, the Series C Preferred Stock, the Class A Common Stock, and the Class B Common Stock were acquired with available capital of the applicable Insight Fund.
 
The Reporting Persons may be deemed to be the beneficial owner of, in the aggregate, 13,545,545 Shares.
 
Item 4.	Purpose of Transaction.	
                                                                                
The Insight Funds acquired the Shares for investment purposes.  The Reporting Persons expect to evaluate the Issuer’s financial condition, business operations and prospects, the market price of the Shares, conditions in the securities markets generally, general economic and industry conditions and other factors on an ongoing basis.  Accordingly, the Reporting Persons may, subject to the restrictions contained in the securities laws, dispose of some or all of the Shares or other securities in public or private transactions.  Any such transactions may be effected at any time and from time to time.

Item 5.	Interest in Securities of the Issuer.	
 
Each share of Class B Common Stock is convertible at any time by the holder thereof into one share of Class A Common Stock. Percentages in this Schedule 13D are calculated in accordance with the rules of the SEC based on the quotient obtained by dividing (i) the aggregate number of shares of Class A Common Stock and Class B Common Stock beneficially owned by the applicable Reporting Person by (ii) the sum of (A) 9,000,000 shares of Class A Common Stock outstanding as of March 29, 2017, and (B) the number of shares of Class B Common Stock beneficially owned by the applicable Reporting Person. Any conversion of Class B Common Stock into Class A Common Stock will be made pro rata among the Reporting Persons.  The aggregate number of shares of Class B Common Stock beneficially owned by the applicable Reporting Person as set forth in clauses “(i)” and “(ii)” of this sub-clause (a) are treated as converted into Class A Common Stock only for the purpose of computing the percentage ownership of the applicable Reporting Person for purposes of this Schedule 13D. To the Reporting Persons’ knowledge, no Shares are beneficially owned by any Scheduled Person.
