Also use fewer words. This message is needlessly complicated with flowery language. Get to the point: do X by this deadline.
Also you have a few sentences that sound like nonsense. Maybe you are missing some words there.
As a new manager in a small team of startup, I am still learning how to handle a low performer in the team. We don't have too many resources to handle the HR and things like that, so some of us have to wear many hats.
Please help with comments and critics, thanks.

Re: Letter of Performance Improvement Plan
This is a formal Performance Improvement Plan to notify you that your performance is not meeting expected levels of contribution. In your job as a Business Development person, the job expectations were developed by our early founding team, which I offer you to submit a job proposal, and me. This means that they will be the accepted standard for each Business Development’s performance for future peers and xxxx in general.
You are showing improvement indication to perform xxxx's operations in the following ways.
• Planning: the number of planning that you have done is quantitatively as well as qualitatively way below what it needs for a startup to grow, or in other words you seem not having challenging and competitive goal.
• Problem solving: you seem to be passive with assuming ownership/ responsibility, decision making and informed risk taking.
• Result orientation: you seem struggling to increase the effectivity of the teamwork and throughput.
From my conjecture, you will not be showing successful result if you do not embrace change for those three important performance measurements for your job. I am open to discuss with you about any concerns and difficulty that you might have related to the job. I sincerely hope that we can help you to have more elevation on those areas. Please understand that I will not tolerate mediocre mentality in a startup environment from anyone in the team.
We need to see an immediate improvement in all three areas of performance follow up with more detail work assessment and measurement by the next three months or we will decide what is necessary to help you finding the best place/ function to grow. We have faith that you have the capability to improve. We need to see immediate improvement.
