Babelgum’s chief operating officer Michael O’Callaghan will leave the P2P online video platform, we have learned and confirmed with the company, the latest in a series of high-level departures at Babelgum this year. O’Callaghan is based in Dublin; the company is headquartered in Ireland for tax reasons.

In the last 13 months, the CEO, CTO and COO jobs at Babelgum have all turned over. It started with the decision to replace original CEO Erik Lumer with Valerio Zingarelli last year, which has proven unpopular with some others inside the company. Original CTO Mallku Caballero and his chief architect, Gianni Scenini, left earlier this year in opposition. The new chief architect, Egidio Corsini, was recently promoted to fill the CTO post.

Prior to Babelgum, O’Callaghan had been VP and GM for Oracle’s European development center in Dublin, and its European chairman. Babelgum, which competes with the likes of Joost and iPlayer, is heavily financed by billionaire Italian telecom tycoon Silvio Scaglia. Since Zingarelli’s arrival, Babelgum has also been trying to carve out a niche creating independent films and documentaries.
