Ask HN: Are There Any Tech-Based Family Businesses?

The art of software engineering is becoming an old practice, spanning generations back into the 60's. Many people also consider software engineering as a craft, similar to wood-working in many ways, where it takes years to master and should involve apprenticeships from experienced engineers.

Something very common in other craft industries is the father-son/family business. I curious if anyone has heard or seen any tech-based family-business?
