It heavily, heavily depends on what the startup is, who the person running it is, what the terms and everything for payment would be, and what the outlook for the startup in the local area would be.

I would be interested in investing in a startup if enough information was being provided, and I would invest partially to make money in repayment and partially to get some people doing more things with their lives that are more meaningful, such as running their own business.

How much of my time and money? Again, it depends. I likely wouldn't be investing much time into it, partially due to location restraints.

Will Bitcoin have much of an impact? Maybe, however I would personally doubt it to be honest. I do not believe there are enough people connected to the internet with enough interest existing for people to want to enter into the Bitcoin economy and have it benefit the African economy at large.

Sorry but I will not invest in any African bitcoin startup.  Not being a racist but I have joined many new altcoins that gives like a hundred thousand coins at first that you can buy for a little amount of bitcoin.  And after the launching date, you will see how low its price and you have to again spend some of your bitcoin to vote for it to have a good value.  Then, you will just found out that its developer is nowhere to be found.  Just came from my experience. 

I do not invest into remote projects with random partners.
But definitely this community will stand up to help and guide you if you have enough reasons like spreading out bitcoins across African continent countries.
Recent devaluation of Zimbabwe currency is an example where bitcoin could be a permanent solutions. Find opportunities. Innovate solutions.

An investment in Africa would only be possible in countries with a stable political environment.
So, no country from middle Africa, because there bribery and and selfenrichment of the officilas are just too high.
Southafrica would be a possible solution for making the first steps.
In general I think there is a lot of potential for cryptocurrencies in Africa.

the community would support LEGIT projects where investors can do due diligence to ensure its not a shell company using a POBox, that does not even have any legit assets to freeze should the business "get hacked"(go bankrupt)

as for the OP managing it. i think that wont ever happen, for reasons he knows

but one tip for him..
"mining contracts".... in africa.. sorry that just wont work

What countries of Africa? Are you helping them or just making money? Well, the kind of projects are so superficial ideas, maybe you can put some info.
I think the blockchain can help a lot more than bitcoin, think about that.

This!

On my part a decision to invest in a startup is not primarily dependent on where the startup is located but whether the startup has a credible business model for the location it operates in and whether it is likely to be a scam or not. I general, the more remote the location and the less verifiable business claims are the less likely it will be an investment case.

The vast majority of "investment" projects circulated around this forum are either scam or lead by naive amateurs with zero chance of success. In fact, I have yet to see a project that qualifies as a suitable investment with a positive risk/reward-ratio. Most project leaders don't even provide a qualified business plan with a calculation of costs that is able to justify that investment is needed at all.

The thread opener's project seems to be no different.

ya.ya.yo!

Steve jobs is dead you will not to invest it right now but you can invest it for apple siblings if they are accepting bitcoin for invest.. and  i think it is hard to invest using bitocoin because they dont want it.

there are many legit businesses that can make returns.
but for the OP after reading his previous posts and attempts to gather funding,
i think that this is not the topic to give him idea's to scheme(i said scheme not the other similar sounding word) the community. the OP doesnt seem interested in actually running a business legit business that gives returns.
but more so running a funding round .. and then... just running

so lets not help him out by telling him anything legit, or he will just use it later to 'scheme' people by pretending his 'scheme' is just as legit
