symmetric monoidal (∞,1)-category of spectra
categorification
A linear magmoid is a magmoids whose hom-sets are all vector spaces (or modules) and whose composition operation is bilinear. This concept is an oidification of the concept of nonassociative nonunital algebra.
Fix a commutative ring $K$. (Often we want $K$ to be a field, such as the field $\mathbb{C}$ of complex numbers.)
A $K$-linear magmoid is a magmoid enriched over $K\,$Mod, the monoidal category of $K$-modules with the usual tensor product. (Note that we usually speak of $K\,$Vect instead of $K\,Mod$ when $K$ is a field.)
Any linear category is a linear magmoid.
A Lie algebroid is a linear magmoid that is not a linear category.
