How to tell them apart
始める describes a clear, deliberate starting point for an action or state, like 集め始めた marking when stamp collecting began. 出す focuses on something hidden or hard to reach suddenly appearing or being brought out, such as 考え出した for an idea that was latent. Swapping them feels off: you would not say 探し始めた when the nuance is finally uncovering something that was concealed.
- 始める・はじめる Use 始める when someone or something simply starts an action or state at a recognizable point in time.
- 出す・だす Use 出す when something latent or hidden is finally realized, found, or brought out.

始める・はじめる meru hajimeru
Start doing; take up
始める means to begin doing something. When written with a verb in the masu-stem form, as in 動き始める, it means that action starts; it can also stand alone as a verb taking an object, as in スポーツを始める. It works in both casual and polite speech.
-
春になったら、私は新しいスポーツを始めるつもりだ。
When spring arrives, I am going to take up a new sport.
-
私たちはすぐに魚をとりはじめることができました。
We were able to start catching fish soon.
出す・だす su dasu
To start doing something suddenly or without warning
出す adds the nuance of something starting abruptly or suddenly. As a suffix it attaches to the masu-stem of a verb, as in 長くなりだす. It also works as a standalone verb meaning to put out or submit, seen in set phrases like 口を出す and 手を出す, which often appear in negative commands.
-
春には日が長くなりだす。
In spring the days get longer.
-
人のことに口を出すな。
