Best way to describe "turning ideas into reality"

Solution 1:

To materialize can convey the idea:

• To cause to become real or actual: By building the house, we materialized a dream.

Solution 2:

"He realized his grand idea in the form of..."

[Or, the more anachronistic but electrifying "reified"]

Solution 3:

Consider the verb execute

Carry out or put into effect (a plan, order, or course of action): the corporation executed a series of financial deals [Oxford Dictionary Online]

The term is often used in business to indicate decisive implementation. The term executive is directly related, as one who is charged with bringing something to fruition. You might say

Some companies play with ideas. We execute.

Similarly implement

Put (a decision, plan, agreement, etc.) into effect [ also ODO]

Solution 4:

We manifest reality where there were only dreams.

Solution 5:

Flesh out [1. [MWV] (tr) to give substance to (an argument, description, etc): Collins] is often used:

the theorists have fleshed out a variety of scenarios [ODO]

'Realise' is a synonym of 'materialize', but both have more common senses and are thus perhaps a poorer choice.
