Answer

Yes. In the Digambar Jain tradition, the commonly mentioned main Acharyas connected with these reform movements are:

• Terapanth / 13 Panth: Āchārya Bhikṣu is the main founder-acharya of the Terapanth tradition.
• Bisapanth / 20 Panth: There is no single universally accepted “founder-acharya” in the same way. Bisapanth represents the older Digambar temple-worship tradition, especially associated with practices like worship with offerings.

Explanation

In Digambar Jain history:

• Bisapanth means “twenty-sect” and is generally understood as the older ritual-oriented Digambar tradition.
• Terapanth means “thirteen-sect” and arose as a reform movement against certain ritual practices. Its principal founder is traditionally known as Āchārya Bhikṣu.

Takeaway

The main name clearly associated with 13 Panth / Terapanth is Āchārya Bhikṣu. For 20 Panth / Bisapanth, Jain tradition does not usually identify one single main acharya as its founder.
