• Koramangala became the startup hub of the city when cheap commercial space, a founder pipeline from IIM Bangalore nearby, cafe culture, and venture capital all landed in the same small area; the 4th and 5th Blocks around Sony World Junction remain the densest startup cluster.
• It is one of the most densely populated parts of Bengaluru, with a residential density above 22,000 people per square kilometre across its eight blocks.
• Unlike the eastern tech corridors, Koramangala is not yet served by an operating metro line; the Pink Line that will pass through it is still under construction, so for now buses and road transport carry the bulk of public commuting here.

A few arterial roads carry almost all bus movement through Koramangala, and they happen to run past its biggest offices, retail, and crowds. Buses on these stretches pass the startup blocks, the mall, the breweries, and the college and hospital gates, which is what makes them the high-visibility routes.

Koramangala has its own BMTC depot and TTMC, so a large number of routes either start here or run through on the way between South Bengaluru, the Outer Ring Road, and the central business district. The routes below are the high-frequency ones covering the startup blocks, the mall, and the main junctions. Numbers and exact stops are easy to confirm on Google Maps or BMTC route search, since a from-and-to search through Koramangala lists the buses on each road.

• The 163 family and the K trunk routes are the workhorses through Koramangala, threading the Forum mall, Sony World Junction, and the BDA Complex, which are the points with the most office and retail footfall.
• Because Koramangala sits between the central business district, the Outer Ring Road, and Electronic City, many through routes pass its edges on Hosur Road and the Inner Ring Road, adding traffic beyond the buses that terminate at its own depot.

Route numbers and coverage compiled from public BMTC route listings and map-based route search for the Koramangala area; services and frequencies are revised by BMTC from time to time.

The corridor is studded with stops along 80 Feet Road, the Inner Ring Road, and Hosur Road. These are the busiest, where startup, retail, college, and hospital footfall concentrate, so a branded bus halting here gets long viewing windows from a waiting crowd.

• Koramangala carries a heavy daytime and evening floating population on top of its residents, drawn by the startup offices, the colleges and hospital, the Forum mall, and a dining and nightlife scene with over a hundred restaurants and several breweries.
• With no operating metro yet, BMTC buses and road transport handle most public commuting in and out of the blocks, so branded buses on these routes reach a large share of the people moving through the area each day.
• A separate bus ridership figure for Koramangala is not published, but for scale BMTC sells more than 30 lakh tickets a day across the city, and Koramangala's depot, central location, and density put it among the busier pockets for buses.
• Peak exposure runs across the office day on the startup blocks, with a second strong window in the evenings and weekends around the mall, the 80 Feet Road high street, and the breweries.
