Mostly true if it was roughly 25–29 or 51–70, since the claim is hedged and approximate. Mixed if it was roughly 71–100 or 15–24. Mostly false if it was about 100–150 or under 15.

Fast Company (E2) reports that Daniela Amodei joined Stripe in 2013 as employee no. 45. A third-party biography (E3) places her joining in May 2013 as roughly the fortieth employee. The Irish Times (E1) reported in September 2013 that the company had 62 staff, which fits a headcount in the 40s a few months earlier. A headcount of about 40–45 falls within the 30–50 range set for a true verdict. E4 only repeats her own remark, so the verdict does not rely on it.
