The party, which had unsuccessfully contested in 39 of the 40 constituencies in the Goa assembly election of 2017, lost its deposits in all of them except two.
The party's state convenor, Elvis Gomes, said, "After the results there was disappointment among the party workers. But we managed to overcome it within two months and the party started working on rebuilding the units."
"The AAP has focused on certain constituencies and we are getting good response from the people there," he said.
Gomes was in Delhi where the party celebrated five years of its foundation.
The party has witnessed its share of turmoil with one of its leaders, Ashish Kanekar, joining the Congress. Kanekar had unsuccessfully contested from the Valpoi segment in the 2017 assembly polls.
Four other candidates had also addressed press conferences criticising the party leadership.
