Quick Verdict
IIT Delhi has the stronger documented alumni network for global tech and entrepreneurial impact: reporting names it, alongside IIT Bombay, as leading the so-called "IIT Mafia" in global tech, crediting its alumni base with over 30 active unicorns worldwide and more than 2,700 founders (source). IIT Kharagpur's sourced alumni list, by contrast, is strongest in public administration, politics, and government service — genuinely notable names, but without comparable startup/tech-impact figures in the available research (source).

Detailed Analysis
The strongest sourced data on alumni impact comes from a 2026 report specifically comparing IIT Delhi and IIT Bombay's alumni networks in global tech, which describes the "IIT Mafia" — a term for IIT graduates' outsized presence in global tech leadership — as being led by these two institutes (source). IIT Delhi specifically is credited with producing more than 30 active unicorn companies worldwide and over 2,700 founders, according to a cited 2026 Alumni Impact Report (source). The same reporting names Vinod Khosla, co-founder of Sun Microsystems, and Deepinder Goyal, founder of Zomato, as flagship examples of this legacy, and references roughly 10,000 alumni holding senior leadership positions across global manufacturing and finance — though the source's phrasing around this last figure is somewhat loosely attributed within the broader Delhi/Bombay comparison, so it should be read as directionally indicative rather than a precise, audited count (source).
That same source also notes IIT Delhi's proximity to the NCR tech cluster and its development in AI and sustainability have helped it outperform IIT Bombay specifically on research impact, even though Bombay is described as having a stronger industry-integrated curriculum and superior employer reputation and employment-outcome scores (source). This context is a three-way comparison involving Bombay, so it should be read as background on Delhi's positioning rather than a direct Delhi-vs-Kharagpur data point.
IIT Kharagpur's alumni network, per its Wikipedia alumni list, is documented differently — its notable graduates are concentrated in politics, public administration, and government leadership rather than the startup and global-tech metrics available for Delhi. Sourced examples include Arvind Kejriwal (B.Tech Mechanical Engineering, 1989), who became a prominent Delhi politician and former Chief Minister of Delhi; Duvvuri Subbarao (BSc Physics, 1969), who became the 22nd Governor of the Reserve Bank of India; Ashok Khemka, a senior Haryana bureaucrat; Chaudhary Ajit Singh, a former Union minister; Surajit Kar Purkayastha, a former Director General of Police for West Bengal; and Ajit Jain, a notable business figure (source). The same list also references an alumnus described as an aerospace engineer and rocket technologist who went on to serve as the 11th Chairman of ISRO (source). It's worth noting Wikipedia itself flags this alumni list with a verifiability caveat, so individual entries should be treated as indicative rather than exhaustively fact-checked (source).
No sourced data was found quantifying IIT Kharagpur's alumni presence in global tech companies, startup founder counts, or unicorn creation — the research available for Kharagpur is qualitative (named individuals) rather than the aggregate statistics available for Delhi.
Verdict
IIT Delhi wins on Alumni Network based on available data — it has quantified, sourced claims around unicorns, founders, and global tech leadership that IIT Kharagpur's sourced profile simply doesn't include, even though Kharagpur's own alumni list features genuinely accomplished names in government, public service, and business. IIT Kharagpur is the runner-up here largely due to a gap in available quantitative data rather than a proven weaker network — a reader should keep in mind that the absence of unicorn/founder statistics for Kharagpur in this research doesn't necessarily mean the network is smaller, only that comparable public reporting wasn't found. A reader should weight IIT Kharagpur's alumni strength more heavily if their interest is specifically in public service, government, or policy careers, where its sourced alumni (a former Delhi CM, an RBI Governor, senior bureaucrats and police leadership) offer a strong, concrete track record.
