Founder’s Office, Entrepreneur in Residence (EIR), and Chief of Staff - Key Differences?
I’m trying to better understand the distinction between Founder’s Office, Entrepreneur in Residence (EIR), and Chief of Staff roles, because the definitions seem to vary significantly from company to company.
A few things I’m specifically trying to understand:
- Relative seniority: which of these is typically the more senior vs junior role?
- Experience level: how many years of experience do companies usually look for in each?
- Compensation bands: what salary ranges are common for each role (especially in India / consumer startups)?
- Company stage / revenue range: what kind of companies typically hire for these roles (early-stage, Series A/B, scaled, profitable, etc.)?
I come from a generalist business background with ~10 years of total experience, including 6–7 years in the consumer space, and I’m considering applying for Chief of Staff roles.
What’s confusing me is that CoS especially seems to change dramatically depending on the founder, company stage, and function—sometimes strategic, sometimes execution-heavy, sometimes almost PMO-like.
Would really appreciate perspectives from:
- people currently in these roles
- founders who’ve hired for them
- recruiters who understand how the market maps these titles
Trying to understand what role level I should realistically target and how these titles ladder into each other.
