Nice analysis; now assuming NEA could also trade at a 150 PE level as WTC (as it has a similar growth profile and with a higher net profit margin once capture and marketing costs stabilise) :

1.WTC is also a software company; mkt cap $6B revenue YE 2018 $220m (2017 153M, 2016 102M ,2015 70M) , PE 150 (6B mkt cap/40m net profit) (profitable, small div yield of 0.17%), 20% net profit margin ($40m net profit/200m revenue)  so similar growth profile to NEA.  
2.so NEA is at almost $1B mkt cap now at revenue 70M per your figures; (lets say 50% net profit margin, I think mgmt says 50%)
3.so at your 2022 revenue of 232m , profit is 116m x WTCs PE of 150 gives a mkt cap of 17.4B i.e future price of: 17 x current $2.1 price gives us about $35....not bad.
