The businesses that run up against the limit are those that hire lower-pay foreigners, which the government doesn't want to encourage anyway. For tech/innovation-driven startups, the limit shouldn't be a barrier.
@sjogress: It makes sense to start a company in Singapore if you're looking to target multinational companies that have their regional headquarters here. Also, if you're considering setting up in Singapore, it's good to have a Singaporean as a cofounder - it makes getting the smaller grants simpler.
@nopzor: Really? Is it an unwritten quota? All the official statements are that there's no quota for Employment Passes[1][2]. It makes sense that the government wouldn't allow a company to be 100% foreigners on EPs, but I think there's some flexibility in how many EP holders you can hire.
@mdda: The advertise-to-locals-first rule only applies to companies larger than 25 people, so it doesn't really hinder startups. We actually applied for an EP for my co-founder (a foreigner) and got it on appeal, with only 1 local employee besides me. As you say, the process is fairly straightforward if somewhat tedious.
