MapThread[#1 @@ #2 &, {{f, g}, {{a, b}, {c, d}}}]

{f(a,b),g(c,d)}

=============
This seems to work fine, but there must be a less clumsy way to do it:

Clear[innerApply, functionList, argumentList, f, g, a, b, c, d]

innerApply[functionList_, argumentList_] :=
 Table[functionList[[j]] @@ argumentList[[j]], {j, 1,
   Length[functionList]}]

In[770]:= innerApply[{f, g}, {{a, b}, {c, d}}]
Out[770]= {f[a, b], g[c, d]}

TIA,
