    Who is FACCTs?

    FACCTs brings innovative computational chemistry solutions to industry.
    We are a deep-tech start-up with first-class contacts to industry and academia. We are a spin-off from
    the Max Planck Society, where ORCA – our flagship program – is being developed. ORCA is combining
    speed & accuracy in quantum chemical calculations. With more than 60.000 academic users it is,
    although the youngest, already the second most popular program amongst its competitors.
    FACCTs offers computational chemistry solutions to the chemical and pharmaceutical industry – with
    currently more than 40 industry partners. We aim at democratizing quantum chemical workflows, i.e.
    enabling scientists and engineers to tap the full potential of quantum chemistry, without the usual
    need for expert knowledge and experience. That is why we also develop new software solutions that
    automate and simplify ORCA usage (using python, React).


    Where is FACCTs located?

    The FACCTs office is located in Cologne, Brüsseler Strasse, near Rudolfplatz. Currently we work parttime remote, part-time in the office.
