Renormalizable QFT has two types of non-perturbative contributions: instantons and renormalons. However, little is known about the latter. In this talk, I will discuss what we can learn about semi-classical expansions by extracting trans-series from the Bethe Ansatz in integrable QFTs. We find finite N results for instantons and renormalons, including previously unknown families of renormalons.
