Four years after the man who built Citi's alumni network walked out the door, the program he left behind is bigger, busier, and — per industry sources — running on software from one of the category's leading enterprise alumni platforms.
A check on alumni.citi.com this week shows a network in good health. The site is live and current, carries a 2026 copyright line, and leads with a message from CEO Jane Fraser. Member spotlights rotate actively. Chapters are publishing fresh content. This is not a program in maintenance mode — it is a program that institutionalised.
That was not a foregone conclusion. Andrea Legnani spent roughly eleven of his 20-plus years at Citi as Global Head of Alumni Relations, building the network to more than 30,000 members across 100-plus countries. When he departed in late 2022, the question hanging over the corporate alumni category was whether founder-built programs could survive their founders.
The answer at Citi: yes.
People familiar with the program told talentmarketpulse.com at the time that Legnani's exit came amid a restructuring of the alumni function — his role was removed, not simply resigned. The public framing was a voluntary move after two decades. Either way, he is now President of Aluminati Enterprises, a UK alumni-platform vendor in the 51–250 employee band — a solid firm, but a long way from the flagship he built.
Meanwhile, the flagship sails on. Industry sources indicate the bank's alumni network now runs on software from one of the category's leading enterprise alumni platforms. Citi has never confirmed its vendor publicly, and we are not naming it here. But the operational reality is visible from the outside: a program of this scale, updated at this cadence, runs on enterprise-grade infrastructure, not spreadsheets and goodwill.
And that is the real story for the market. The 2022 question — can an alumni network outlive its architect — has a 2026 answer with vendor implications. The platform era won.
The corporate alumni category has spent the past three years consolidating around that logic. Once a program is big enough to matter — 30,000 members, a CEO's name on the welcome page — it stops being a relationship project and becomes an infrastructure decision. Boards now treat the post-employment network as a strategic asset: talent pipeline, brand advocacy, deal flow. Strategic assets get enterprise software underneath them.
The vendor market has followed. The alumni SaaS space is consolidating around two or three dominant players, and the long tail of point solutions is being absorbed or abandoned. The leading platforms are the ones investing in AI-native features that make a 30,000-member network actually usable — personalised career roadmaps, natural-language search across the directory, AI matching of alumni to jobs, advisory work and mentoring.
A global bank does not rebuild that in-house. It buys it, deploys it, and lets the program run — with or without the person who founded it.
That is the uncomfortable lesson for alumni professionals: the job has changed. The programs most worth running in 2026 are the ones engineered to survive a departure, any departure, including the founder's. Enterprise software is how large firms buy that durability — and the category leaders are the beneficiaries.
The consolidation dynamic we have tracked all year points the same direction. Leading professional-services firms have migrated onto a small set of enterprise platforms. A major global bank's alumni network — one of the largest in the world — is reportedly on one of them. The centre of gravity in this market is not the consultant with the Rolodex. It is the platform with the deployment list.
Citi's alumni network turns no pages back. It is the category's cleanest proof that the platform era is not coming. It arrived — and it did not need its architect to stay the full journey.
