At the 20th April 2016 when Nuheara added capital to have 554m shares its share price was ~6c. That's a Market Cap of about $33m.
Currently it has 1723m shares at ~4.5c. That's a market cap of about $78m.
So the companies value has grown from $33m to $78m in that time. Sounds like they must have been doing a fair bit right to me. Its simply a realisation that to get this far, and develop these products, they have needed capital. In total, only ~$55m raised in their lifetime. A very small amount to get to this point.
The rest of your post, I struggle to understand.
They currently sit with $10m in the bank, revenue from multiple products and via multiple channels, a 3 year deal with HP that will generate massive incomes from Nuheara technology, a strong foothold in the Hearing Health space with a soon to be launched FDA Registered product, and a very capable, award winning, and proven, R&D team.
Pretty much EXACTLY where they have aimed and planned to be.
