Fundnel does not guarantee returns for investment-based deals. All investments come at a risk which we mitigate with our vetting process, but the final decision to invest ultimately lies with the investor. In the case of secured and guaranteed investments (as is the case typically with bond deals), the guarantee is offered directly to you by the business owners of the companies.
It is important to understand that some investments may take years to realise returns. Private investments are risky and in extreme cases, an investor may lose the entire investment amount.
