The Mentorship Mirage
Almost every accelerator promises mentorship.
But most deliver a short burst—three months, one demo day, then silence.
Long-term mentoring is rare in Mumbai’s accelerator scene. And for founders building over years (not weeks), this is a gap that slows growth, weakens clarity, and increases emotional isolation.

Mumbai’s accelerator ecosystem is still catching up to this reality. The few programs offering long-term guidance deserve credit—but there’s still no comparison to what 1Mby1M offers in consistency and founder continuity.
If you’re building the long way, make sure your support system lasts just as long.
