Our product is designed a pseudonymous p2p insurance solution where all transactions/holdings/members can be audited 24/7/365 on a public blockchain.
The Pseudonymity is crucial because members should not be able to identify other members in their tontine.
Publicly disclosed immutable ledgers is the only way to generate the level of trust (or trustlessness) that is required in order for members to entrust their life savings to a new (albeit regulated) company that is not a 150 year established life insurance company.
Tokenising the Tontine Member Contributions (TMT) means that we are effectively creating a new (regulated) asset class which does not need to comply with legacy insurance rules which would add overheads and decrease returns for members. (These are likely to be regulated under money transmitter and/or SEC rules in the US) 
The (seperate) utility token (TON$) are designed to solve ceratin problems within the Tontine Platform:
1)The tontines are going to have underlying assets in multiple currencies approximately 0.9%+ of which will be liquidated every month and then paid to members whih could be spending their payouts in any global currency. The TON$ allow us to have a single currency to convert to and distribute where we can avoid FX fees for members.
2) RIAs and any oher investment advisors globally will really only ush the platform if they get paid commission. We wanted to find a simple way to keep them honest. We also wanted to pay them without touching the clients capital.  
2.1) To qualify to receive commissions, the investment advisor must buy and lock down TON$ in their wallets as a stake that we can draw against in case of any customer complaints (mis-selling) which require compensation. This simplifies our onboarding process for distributors and is likely to keep out undesirables.
2.2) The Token Sale creates a liquid tradeable asset in the TON$ which can be used to pay commissions to the advisors/distributors. 33% of TON$ created will be reserved for this purpose. This could be sufficient to pay commissions for the first $2-$3bn+ of AUM.
