<p>I should add something about this, but if a market looks like a drunken bar fight, I'd probably not want to go there.<p>That said: A good market will become crowded quickly in either way.</p>

<p>Yeah.<p>Also - I use the term "coach" broadly here. Many people react very poorly to the term "therapist", and "coach" is a much broader term encompassing both therapy or just people that have significant experience in a field. Or just an older relative or acquaintance that is willing to provide regular advice/feedback.<p>There's definitely charlatanism, particularly when people advertise themselves as "business coach" or "startup coach".</p>

<p>Yes. Usually, the VCs will want you to not take an extravagant salary, but a solid family with which you can keep your family comfortable. And that's normally the right bar.<p>And if there are liquidity pressures a few years into the process, and you have traction at Series B or C - don't hesitate to think about a small secondary.</p>

<p>You don't have a product until there's ~3 customers, with perspective to more. Before that you're essentially a consultant. I'll add that to the next version of the doc, too.<p>The point is: For anything you build, you can find <i>1</i> customer. It's only when there's multiple customers that like the product and want to improve it where you move from "consulting" or "custom development" to "product".</p>

<p>I will add a section. Pay yourself a salary at the very latest the moment you've raised funding. If a VC objects to you doing that, get a different VC. You're in for the long run, and support from your family etc. is important, <i>and</i> you're already taking on a huge risk by pooling all your risk in one company, vs. the VC who is happily diversified.<p>Investors who imply you shouldn't take a salary are no bueno.</p>

<p>That's a clever and intriguing idea. I have to think through the security implications a bit though - I don't actually know much about how git operates with regards to hooks etc.<p>I'd imagine you lose the ability to have the coding agent do the commits for you? E.g. if you just mount the code directory, then an agent running on the remote side can't commit anything, right?<p>So you'd have to mount the .git directory from the remote side to then push?</p>

<p>The old warez cracking scene had an outsize impact on computer security. GRSecurity, Heartbleed vulnerability, most reverse engineering tools for security, etc. etc. etc.<p>There's so much history here, touching on all sorts of insanity including selling 0-day to the US government that was then used to apprehend high-level Al-Qaida personnel, random warez busts leading to people taking oversea jobs, etc. etc. etc.<p>If anyone still has old .NFO archives from 1990-2000, I'd be very interested in getting as many as possible.</p>

<p>The privatization of the train system in Germany was a particularly insane disaster that is only now, 30 years later, being undone/repaired.<p>If you look at an org chart of the DB these days, the most fascinating part is that DB consists of almost 600 separate corporate entities that are all supposed to invoice each other.<p>Speaking with insiders, it appears that when the privatization happened, the new corporate structure took what was essentially every mid-size branch of the org chart and created a separate corporate entity, with cross-invoicing for what would normally normal intra-company cooperation. I think the (misguided) goal was to obtain some form of accountability inside a large organisation that had been state-funded and not good at internal accounting.<p>This fragmentation lead to insane inflexibility, as each of the 600 entities has a separate PnL and is loathe to do anything that doesn’t look good on their books.<p>Add to this a history of incompetent leadership (Mehdorn, who also ran AirBerlin into the ground, and who was also responsible for the disastrous BER airport build-out), repeated rounds of cost-cutting that prioritized “efficiency” over “resiliency of the network” etc. etc.<p>DB is currently undergoing a massive corporate restructuring to simplify the 600+ entity structure, but there has been a massive loss of expertise, underinvestment in infrastructure, poor IT (if you see a job ad for a Windows NT4 admin, it’s likely DB), etc. etc. — it’ll take a decade or more to dig the org out of the hole it is in.</p>
