I'm trying to find the next level of wealth status, i.e., millionaire,
trillionaire, what comes next?

Hello bdp-ga

Based on the U.S. classification used in mathematics and science as
documented at
Jimloy.com
http://www.jimloy.com/math/billion.htm

The wealth line up is as follows:

Millionaire (6 zeros)

Billionaire (9 zeros)

Trillianaire (12 zeros)

Quadrillionaire (15 zeros)

Quintillionaire (18 zeros)

Sextillionaire (21 zeros)

Septillionaire (24 zeros)

Octillionaire (27 zeros)

Nonillionaire (30 zeros)

Decillionaire (33 zeros)

Undecillionaire (36 zeros)

Duodecillionaire (39 zeros)

Tredecillionaire (42 zeros)

Quattuordecillionaire (45 zeros)

Quindecillionaire (48 zeros)

Sexdecillionaire (51 zeros)

Septendecillionaire (54 zeros)

Octodecillionaire (57 zeros)

Novemdecillionaire (60 zeros)

Vigintillionaire (63 zeros)

Undecillionaire - Vigintillionaire (60-120 zeros)

[classifications seem to get a bit vague up here!]

Centillionaire (303 zeros)

However...  above this is Googolaire!
Which is based on Googol, which Google itself is based on:
://www.google.com/corporate/history.html

But the ultimate is a Googolplexaire!

Excerpt detailing Googol and Googolplex
"A googol is 10^100. A googolplex is 10^googol (10^10^10^2). This
number is too large to write here without exponents. Skewes' number
(gesundheit) is 10^10^10^34 was used as an upper bound in a
mathematical proof. Recently 10^10^10^10^10^7 was used in a proof.

The googolplex has given rise to the n-plex notation: n-plex is 10^n.
n-minex is 10^-n. Donald Knuth invented arrow notation, where m^n (^
is an up arrow) is the regular m^n. m^^n is m^m^m^m...^m, with n up
arrows. m^^^n is m^^m^^m...^^m, with n ^^s. According to The Book of
Numbers by J.H.Conway and R.K.Guy, chained arrow notation is the
following enhancement: a^^^^^b is written as a>b>5, where > is a right
arrow."

I hope that helps, if you need any clarification of the answer just
ask.
