  • Blinkit/Zepto public announcement of fashion category expansion or dark-store SKU addition
  • FastBox city launch count and dark-store footprint over next 2 quarters

  • Additional funding rounds or investor names (esp. any strategic from fashion retail)
  • Founder/team attrition back to Instamart/Zepto ecosystem as signal of stress
  • Launch pilot dark stores in 1-2 metro micro-markets (likely Bangalore given founder base) within 60-90 days
  • Sign exclusive/early supply deals with D2C fashion brands seeking fast fulfillment channel
  • Hire ops leadership from Myntra/Ajio/Instamart for reverse-logistics and returns handling
  • Raise Series A within 9-12 months contingent on GMV/repeat-order proof
  • Watch for Blinkit or Zepto announcing dedicated 'fashion' vertical or brand partnerships
