What is the connection between BitSE and Qtum?

Scianna, Dai, and Niel all worked at BitSE. BitSE was collaborating with PwC, as Qtum was for development of DGP. BitSE not listed in Qtum Whitepaper, though (seems strange to me).  

Qtum and VeChain seem to be projects of BitSE, but VeChain (VEN) is building on the Ethereum blockchain, although roadmap says 2018Q4, "Integration with IoT, and more specific industrial blockchain cloud," which I suspect could mean building on Qtum. Additionally, integration with IoT may be foreshadowing Trusted IoT Alliance membership with CISCO among many others... https://tokensale.vechain.com/en/#timeline    http://www.trustnodes.com/2017/07/26/cisco-leads-blockchain-based-trusted-iot-alliance  

Both Qtum and BitSE listed as partners of Trusted IoT Alliance https://www.trustediot.org/membership     


Can someone clarify this? Information past what I have gathered doesn't seem to exist online...
