Must I have a co-founder at the EARLY STAGE of my startup/business especially if I can comfortably handly the Technical aspects, Business development/execution, and early funding needed for the initial launch of the Project?
Kindly give your opinion preferebly with proven references. Thanks.
Yes and here are the advantages
1 - The main advantage is that a good co-founder will challenge your personal assumptions and drive a better business and product development process. For this reason, pick someone whose independent judgement you trust and who really groks the overall vision. It is not easy to find that combination.
2 - The second main advantage is that having someone else on-board makes you more accountable to the milestones and goals you have set for yourself and makes failure less acceptable.
3 - A co-founder who complements your technical skillset can make a difference in the formative stages of the company. Some examples - Jobs / Wozniak, Gates / Ballmer, Lazaridis / Balsillie.
There are plenty of counterexamples too though - Sergey / Larry share the same technical skillset. The Twitter co-founders all have similar technical skillsets etc.
My problem with this advantage is that it often turns into disadvantage #2 above.
4 - Despite all the supporting resources and networks around you, at the very early stages, a startup is truly just about you looking at your vision shining in the distance on a mountain of risks, work and people telling you it can’t be done.
TL;DR Having a co-founder in your business makes it a lot less daunting.
Not Compulsory…but any investor will like to know your Team and then at that Early Stage you cant juggle all the balls so to speak…you might find one of the areas you have to focus on will suffer because youre stretched too thin best you give someone else who believes in your vision and complements you the chance to work together, you can give him or her equity for work as you see fit.
you don’t need a co-founder if you have fans, email list of potential customers or subscribers already. If you don’t have any of those make sure you have enough capital to fund your business or a VC funding your business or try and start building a potential customers list.
For example:
one of my reskinned apps
Linda Ikeji’s app

My brother, this journey of building a business is very hard. If u have a dedicated and passionate person that could become a cofounder, take him/her.
Down the line, it gets really difficult to navigate. Your cofounder will become your fucking rock! So hear this! If u can, don’t go it alone.
Thank you!
I can’t get my head around your submission. Kindly rephrase.
i just tire…
For me personally having a co-founder has been critical for okadabooks.com.
We are polar opposites in every regard. I like things done fast, I am a scatter brain with my ideas, I want things done NOW NOW … but my partner is mega organized, needs things detailed and packed neatly in files, takes his time, analyzes solutions in a pattern.
He drives me crazy, I drive him crazy at the end of the day our craziness drives the company forward. Because we take the good from each of our traits. He pushes me to be organized and I push him to be flexible in execution.
WARNING: We are able to survive each other because we both listen to each other and speak out without holding too much in. Plus we have a past history, we both went to the same University. So yeah, that’s my N145, without my partner I would have given up years ago.
It’s like you just described my relationship with my cofounder, plus the history and everything. Oh, guess who’s the scatterbrained one. 
If you can’t convince someone to join you on the journey, it’s probably a bad idea. There is a lot of materials out there on why a partner is needed. Beyond complementing, it’s exhausting to run this thing by yourself. I’m sure many persons here, have tried it.
If you have fans & email list
you’re very predictable…
Engage people with what they expect; it is what they are able to discern and confirms their projections.
It settles them into predictable patterns of response, occupying their minds while you wait for the extraordinary moment — that which they cannot anticipate
No wonder you are the Chief Mechanic Officer. That was just hilarious but cool
You no de over look something? Anyway I’m glad I got another GIF to boost my arsenal for my anticipated GIF war
Him Right? 
Lol…
You know nothing jon snow…
Except you are “Rambo or Jet Li” you need a co-founder…
Or Fadeyi Oloro or Abija.
On a more serious note, having a co-founder goes beyond what you see on the surface. Iron sharpens iron. Its most unlikely both of you will be discouraged at the same time equally. One pulls the other up. Its not compulsory if success in your start up is your priority (I discovered lately that people push startups or several hilarious reasons)
Not compulsory but I guess @wyko and a couple of others have made good arguement as to why its great to have one.
I will add that a cofounder helps you speed up development and launch. So if you intend to go to market fast, then it may be of advantage to have a cofounfer.
However, there are great companies that have been built by a one-man founder team. This is mostly the case when you are bootstrapping or have a ready to market prototype.
