<p>So basically I'm wondering how you start your own firm in engineering like aerospace, biological, or bioinformatics. I'm pretty sure that as I'm older maybe early 30s after I possibly complete graduate level courses, I would like to run my own business. I've always loved the idea of running something, or having something be my own. I just have a really hard time envisioning how engineers or bioinformaticians (my applied science of choice) run their own company considering that the projects they work/collaborate on are sometimes in a large scale.
For example with aerospace: Projects like airplanes, spacecraft, or creating engines and propulsion systems seem like things only HUGE companies would want-projects that can cost in the 100's of millions of dollars. I know aero engineers do smaller things associated with materials science or acoustics, but who (thinking on a small, non fortune 500 company level) would want these kinds of tests done?
For example my dad runs his own architecture firm, just himself no other employees and he does residential architecture so it's relatively easy to start a business in that way. Maybe I just have trouble seeing the big picture and can only envision small scale things.</p>

<p>Basically, what are the chances that someone starts their own business in this type of field? I really don't want to end up working for a firm my whole life.
It would be awesome if you could give me examples/explanations of this especially for bioinformatics and aerospace/biological engineering.</p>

<p>Many thanks in advance.</p>

<p>I’d really like to know this too - I like the idea of being involved with technology, but I don’t see how any firms but the big ones can undertake any significant projects. On the other hand, I would prefer working for myself. What a dilemma…</p>

<p>Anyone that has input, please chime in. It would be much appreciated.</p>

<p>My best advice (I’m in a similar situation, I would like to have my own business and I won’t have my BS until I’m in my early 30s) is to read up on the histories of successful (and, if possible, unsuccessful) companies started by engineers and scientists, and the histories of successful tech companies in general. Granted, the “rules” in the tech industry change often, but you can still learn from, say, the history of Apple or Nintendo.</p>

<p>Hmmm, thank you for your reply. So it seems like all companies that large now start small then grow big, which makes sense. I mean its not like its really all that possible to have a small, local engineering firm of some kind. I think it’s time I forget about that “image.”
And I wasn’t saying that I’ll have my bs when I’m 30, I’m actually only a junior in high school. I was just saying that I would like to work for a company at first to learn the ropes so to speak, then when it’s time to move on to bigger things in life like a family or starting a business (all around my 30s hopefully)</p>
