Scenario
In this scenario, the firm is very pleased with your first report
and the owners of the firm, Rick Horton and Dave LaPoint, are
looking to you for assistance again. The firm has recently been
formed and has several interested investors, but they are
deciding where and how to invest their firm’s capital. You have
just completed a recommendation that focused on the various
industries they should invest; the board was impressed, but they
want more tangible information. You will write a two- to three-
page report on recent venture capital deals that the firm may
have invested.
Your Role
You are a new investment analyst at Horton and LaPoint
Ventures, and you have been asked to evaluate potential
investments that were recently made. The board enjoyed your
report, but they want to see what types of real investments that
may have been made. In Doc Sharing, you will find a file called
Top Deals of 2013. Please review this list of 10 companies that
were recently funded and report back to the board about which
of these you would have recommended to invest. Please note,
this does not need to tie into your previous report, so you do not
have to pick an investment that fits your earlier
recommendation.
Activity
For this assignment, you will draft a two- to three-page report
that will be given to the company’s Board of Directors at their

next board meeting. You need to look at the list of 10
companies that were recently funded as reported by MoneyTree,
and then write a recommendation on which three of these
companies you would have picked to invest and why you would
invest. Please be sure to research each of the companies and be
sure to support your recommendation with data and facts about
each business. This analysis should draw upon the material
given in this course, as well as any outside research that you
need to conduct in order to complete the report.
Be sure to listen closely to Mr. Horton and Mr. LaPoint,
because they will give you clues on the type of information they
want in this report.
Good luck!

Mr. R. Horton, Cofounder of Horton and LaPoint Ventures
Hi,
Great job on your first report to the board! It was very well
received.
Although the board found the information interesting, they felt
like they needed more information and tangible data.
With that in mind, we would like you to write another
recommendation based on real deals that have recently
transpired. We want you to research the big deals in the first

quarter of 2013, and tell us which of these three you would have
recommended to invest.
Although we liked your recommendation on what to invest in
last week, you do not need to use those criteria for this report.
Davy will give you more information on how to structure this
report and specifics of the task.
Again, great work on the first report. I expect the same level of
detail in your follow-up report.
Have a great day!
Mr. D. LaPoint, Cofounder of Horton and LaPoint Ventures
Thank you Ricky, have a good day.
I would agree with Mr. Horton on your first report; it was well
done.
In this report, please view the document that you can find in
Doc Sharing called Top Deals of 2013. In this report, you will
find 10 companies listed that have recently received some
funding. We recognized that it is too late to invest in these
ideas. We want to get a postmortem report on the companies we
might have invested in if we were in a position to finance these
deals.
Please review these companies and look at their websites and
their product or service offerings, the financials (if available),
their industries, and any other important and pertinent
information, and let us know what you think.
Like last time, we want you to pick three of these companies
and rank them in order. Tell us a little bit about each company,
and then tell us why you would recommend each of these for
our firm.

Be sure to do solid research and cite your sources. I look
forward to reading your analysis. Have a great day!

demonstrate understanding of how the course concepts apply to
the problem. Be sure to have a comprehensive description of
each company and supporting data. Be sure to rank each of
these items and justify each ranking with data. Show creativity
with the assignment and outline interesting recommendation.
Understanding

Be sure that you show mastery of the course content. A
demonstration of research outside of the course work will be
evaluated. Did you find criteria that are not explained in the
details? What data did you collect that are relevant to this firm
and industry? Did you present the information in an organized
and concise manner?
Execution
10
Write your recommendation clearly and succinctly using strong
organization and proper grammar. Use citations correctly. Is it
two or three pages? The founders want a short report that is
concise. Going over the allotted three pages will be penalized.
