> https://github.com/holman/extended-exercise-windows This is a nice list, thanks! No idea how complete that is, but it lists roughly ~160 companies. Which is nice, but according to [1] there are about 71K startups in the US. (Of course both of these counts might be wrong but let's go with these numbers.) So about 0.2% of startups have extended exercise windows. Not a lot ;-( [1] https://github.com/holman/extended-exercise-windows
In Silicon Valley's best kept secret: Founder liquidity
Anecdotally, i've received more offers in the last ~5 years with extended window. I think it's just natural evolution due to increased competition for talent with high-paying public companies. Here's an incomplete list btw[0]. There are usually some strings attached - e.g additional cliff to qualify (like 2-3 years with the company) and you need to sign a separation agreement when leaving, etc > That's a huge number though, I'd never gamble that much either. I've been offered early exercise of 25k options with a $2 strike price. Series B startup. So yeah... [0] - https://github.com/holman/extended-exercise-windows
In Silicon Valley's best kept secret: Founder liquidity
Google pays for on call but it is absolutely the exception in the US. Most Silicon Valley tech companies do not - it’s considered part of the job. Paying for a call is an elegant solution when you have a massively profitable business. Comp days like you are describing are more common, but often informal arrangements. It would be informative if someone made a list like the extended exercise window list [1] for on call practices and comp if it exists However one piece of conventional wisdom - on call rotations should be no less than eight people, and not much more. Going on call any more than one week in two months leads to burn out. Any less frequently than that you risk losing familiarity with on call procedures, the observability systems, etc. [1] https://github.com/holman/extended-exercise-windows

Ask HN: How can employees protect themselves against expiring equity?

It seems like there's a trend for companies to stay private longer and longer. Double trigger RSUs can't be granted with an expiration longer than 7 years, and options can't be granted with an exercise time longer than 10 years after leaving the company (Zach Holman keeps a handy list of companies granting 10 year exercise windows here [1]). So where does that leave employees? It feels like the calculus on joining early stage startups doesn't seem worthwhile anymore - before you were lucky if you had a liquidity event at all, now you have that plus if it happens at all it's very likely after your shares have expired and the company has no obligation to renew them or make you whole. Is there anything prospective employees can do to protect themselves? Just join later stage / public companies? [1]: https://github.com/holman/extended-exercis

> If you leave the company, your options will expire if you don’t exercise them. Let me repeat that: if you leave the company, your options will expire if you don’t exercise them. The exact timeline of how quickly they expire depends on option type and company policy, but the termination window is commonly as short as 90 days. So, exercising your options enables you to actually own what you helped build. This is why I choose to not work for companies that do not have extended exercise windows -- and IMO neither should you.

In What should you do with stock options during a recession?
If I am not mistaken, Amplitude was the very first SV startup coming up with the idea of the 10-year post-termination exercise window, talked to lawyers who said it cannot be done, persisted and did it anyway late 2015, then open-sourced the approach for others to follow [1]. Triplebyte made a splash by adopting a very similar policy months later in early 2016 (also discussed heavily on HN [2]) and all YC companies were recommended to adopt this approach off the back of Triplebyte starting from the W16 batch [3]. The rest, as they say, is history. Many companies on this extensive list of ones with 10-year post-terminiation exercie windows [4] might not have this policy if it was not for this know-how benefitting employees put out in the open - between Amplitude, Triplebyte and it spreading to YC, making this approach table stakes a few ye

ars later. Sir, I salute your for doing this not just for doing this for Amplitude employees (who no longer had a "golden handcuff pressure" after vesting their original grant - which is most companies actually see as a benefit, and a way to "leak" less equity thanks to leavers often not being able to exercise), but for a part in moving the tech industry forward.

In Tell HN: Amplitude (YC W12) just went public – AMA
It's usually really hard to negotiate a longer post termination exercise window as an individual, as that will have to be written into the options plan (which requires board/investor majority approval and is generally a huge legal doc written before). However a lot of strong startups these days are offering all employees with longer (e.g. >2 years) experience the opportunity to exercise for 3+ years and sometimes significantly longer. https://github.com/holman/extended-exercise-windows is a good resource!
In Equity guide for employees at fast-growing companies
Bravo bravo bravo! This piece neatly encapsulates all the problems with ISOs. The biggest one is mentioned at the beginning - information asymmetry. I don’t really understand why most companies, especially small ones less than 100 people, can’t be transparent about their cap table with employees. I do think the culture around 90 day exercise Windows is changing. Here is a list of companies with extended windows [1]. At this point I would never join a company with 90 day windows.
