Mobile App Business Launchpad Experiment, often stylized as Mable, is a business accelerator based in Portland, Oregon, U.S., that provides mentorship and resources to select startup companies. The program was informally launched in 2015 before converting to a formal structure in 2016. Mable participants are chosen by a selection committee following an application process. Participants will either then be sent to prepare for an investor pitch and receive limited coaching or be sent to enroll in the app academy accelerator where they spend three months developing their businesses with support from mentors and coaches. Companies that pass through the accelerator may also be provided a seed round of financial assistance.
