So, there are plenty of words available to accomplish this aim, however you should use them in the proper situation. I mention some of them here (please note that some of these words have other meanings too, but I just focus on the related meaning here):

All the meaning and examples borrowed from the Longman dictionary.
I would say facilitator or guide.
The first word to my mind is mentor:
-- an experienced and trusted adviser.
Enabler, one who enables. Not commonly used in British English.
It can also have negative connotations, meaning someone who allows an addict to keep up his addictive habit. (ref psychcentral.com, wikipedia.com )
How about guide?
Especially if "your goal" is a literal mountain peak.
I live in Granada, Nicaragua. When we got our residency, we got help from a professional local who knows the ropes. He is referred to as an 'expeditor'.
muse: Typically a female person or female ethereal presence that inspires creativity and a desire to create and achieve.
Derived from the term used to in Greek mythology to describe Zeuss's nine daughters who presided over the arts.
Used most commonly when inspiration and creativity are primary considerations.
Tough crowd...noting the "sponsor" and "calls for help" referring back to the original question, helping people achieve their goals, these would be strong indicators to me, that the term is appropriate as offered? From Wikipedia:
The Muses were both the embodiments and sponsors of performed metrical speech: mousike (hence the English term "music") was just "one of the arts of the Muses". Others included Science, Geography, Mathematics, Philosophy, and especially Art, Drama, and inspiration. Some authors invoke Muses when writing poetry, hymns or epic history. The invocation typically occurs at or near the beginning, and calls for help or inspiration, or simply invites the Muse to sing through the author.
