At Overtime we love our partnership with Sapphire and Michael, particularly as he helped our latest round come together and was a constant source of encouragement. Sometimes it’s those intangibles, that energy, that belief, that keep you going. Having a partner that doesn’t just write you a check, but believes in you and sticks their neck out and brings other people to the table – that was really, really critical for our business.
