We study integrable non-diagonal open boundary conditions for spin chainsarising from holographic gauge theories. Their dual description is in terms ofopen strings stretching between giant gravitons intersecting at arbitraryangles inside spheres or projective spaces. By studying properties of theirground and low-lying states we reproduce the expected spectrum near theintersections. Unlike the case of intersecting D-branes in flat space,intersecting giant gravitons related by $SU(N)$ rotations do not alwayspreserve an additional supersymmetry. We quantify this lack of enhancement bywhether or not there exists a simple ferromagnetic ground state for the openspin chain.
