  We study previously unexplored possibility of triggering the first order
electroweak phase transition (EWPT) by interactions of the Standard Model (SM)
particles with the sector responsible for low scale supersymmetry breaking. The
low-energy theory apart from the SM particles contains additional scalar
degrees of freedom -- sgoldstinos -- which contribute to the effective scalar
potential and thus can trigger the first order EWPT. Remarkably, the latter
requires only moderate couplings in the scalar sector. The perturbative
description in terms of the effective theory seems formally to be applicable
upto the scale of supersymmetry breaking: the Landau pole in the scalar sector
is above $10^8$-$10^9$ GeV. We calculate the gravitational wave signal
generated at this transition (it can be tested, e.g. by LISA, BBO and DECIGO)
and briefly discuss the collider phenomenology of this scenario.
