Online education provider Edrolo has received a tick of approval from AirTree Ventures, the high tech investment fund headed by former Microsoft Australia chief Daniel Petre and veteran investor Craig Blair.

AirTree​ is the largest of 14 investors who've collectively tipped in $2.6 million to fund the expansion of the fledgling start-up, which offers online teaching and testing to Year 12 students in NSW and Victoria.

Edrolo founders Jeremy Cox, Duncan Anderson and Ben Sze's faith in their company has paid off.

Edrolo's founders Duncan Anderson, Jeremy Cox and Ben Sze met eight years ago while part of the graduate cohort at financial services firm Goldman Sachs JBWere.

The trio went their separate ways workwise​ but regrouped to collaborate on the Edrolo​ concept, before jacking in their day jobs to work on the venture full-time in January 2013.
