RVE.SOL - Solucoes de Energia Rural — Rural populations forced reliance on biomass and kerosene for their energy needs is causing over 1.6M# deaths per annum. Their lack of access to clean water causes over 5M people to die; 2M of them are children under the age of 5.RVE.SOL's _Changing Rural Life Forever_ initiative is creating alternative, renewable energy choices for therural poor, allowing them to take advantage of natural resources like sunlight, cattle manure and raw water to manage their own way to a better future.Our _KUDURA_ rural village energy hub is community managed; provides communities with potable water, solar electricity, biogas for cooking and organic fertiliser for agriculture.A holistic approach, the solution seeks to target the four areas of rural life that prevalently cause poverty to propagate:1. Access to clean water to obviate transmission of water borne disease2. Access to renewable electricity to obviate the dependance on kerosene for light and improve children's opportunity to study at night3. Access to Biogas to obviate mass destruction of primary forest in a bid to be able to cook food4. Access to fertiliser to reinvigorate over-used soils and so increase quality and quantity of crop harvest for subsistence farmers.Ultimately, this approach seeks to create wealth for rural farmers by offering a choie of more cost effective and efficient services utilising naturally available resources.

At a second stage, it intends to invest also in Spanish and Italian startups. While no particular industry will be ruled out from the investment scope, the pledge fund will tend to focus on the broad technology and energy sectors. As a pre-requisite, it will either invest in startups previously vetted by other Business Angels, or co-invest in them with other seed or venture capital funds as partners. The focus of the pledge fund will be to invest in the gap between seed and series A rounds. Upon the investment at this stage, Betwixt Ventures will seek to attract further institutional investment rounds, internationally.On top of the pledge fund management, Betwixt Ventures will also offer both financial and general advisory services to startups. The former include either the attraction of venture capital funds for placement of further investment rounds, or the attraction of strategic buyers for potential M&A transactions, mainly in the US market.
