The most common case is very early stage technology startups where most of their employees wear many hats. They usually have no legal counsel and maybe 1 or 2 developers including a CTO. They need help on everything from employment agreements, fundraising and NDAs to building the newest API endpoint or Airflow DAG.
It's a little strange at first to have someone doing very different jobs for them simultaneously, but when you're that early stage and having difficulty hiring, it's a blessing once you realize I'm highly experienced and hard-working at both.
Strange intersection, but can you give examples?
