In the context of top-quark condensation models, the top-quark alone is too light to saturate the correct value of the electroweak scale by its condensate. Within the seesaw scenario the neutrinos can have their Dirac mass large enough so that their condensate can provide significant contribution to the value of electroweak scale. We analyse the feasibility of the top-quark and neutrino condensation conspiracy against the electroweak symmetry. The resulting effective model is the Type I 2HDM. We demonstrate a significant improvement in achieving simultaneously the saturation of the electroweak scale and the lower mass of the lightest scalar despite of rather limited manoeuvring space for the participating parameters.
