    Frequently Asked Questions

    What did Michael Schumacher learn from his first agency failing?

    Real lessons and strategies that directly shaped how he approached building his second agency, HMDG, discussed in the episode as formative to the specialized approach that followed.

    How did HMDG grow from 10 clients to 800+ in just over three years?

    Through a specialist approach to healthcare marketing, built with co-founder Hannah, scaling rapidly within a specific vertical rather than spreading across unrelated industries.

    Why does speaking clients' language matter so much in healthcare marketing specifically?

    Because genuinely knowing a client's business, industry, and niche builds the kind of trust and relevance that generic marketing language can't replicate, especially in a specialized field like healthcare.

    What made this level of growth possible in such a short timeframe?

    A combination of lessons carried over from an earlier failed agency and a deliberate focus on speaking directly to healthcare clients' specific world, discussed in depth throughout the episode.

    Does rapid growth like this feel more like a blessing or a burden, according to the episode?

    That tension is explored directly in the conversation, the real challenges and opportunities that come with scaling from 10 to 800+ clients in just over three years.
