"It is a no mean achievement. This is a moment of celebration," said M R Rangaswami, a Silicon Valley-based investor, entrepreneur and philanthropist.
He had held fund-raising events for almost all of them.
"It is important that Indian-Americans become part of the political mainstream," he said.
Rangaswami hoped the "historic election" would encourage others from the community to run for not only Congressional elections, but also those at state and city levels.
"We are growing up and growing out," said Sekhar Narasimhan, an activist in the Greater Washington area.
He has been encouraging young Indian-Americans to run for elected offices.
Ajai Jain Bhutoria from California, who too had raised funds for these candidates, said: "This is matter of pride for Indian-American community."
Indian-Americans - one of the fastest growing ethnic groups in the US - this year pooled resources from across the country - through fund-raising events and by volunteering time and effort.
For instance, the Indian-American community in Tampa, Florida, one of the battleground states - held fund-raising events for Raja Krishnamoorthi, while those in the greater Washington area raised money for Ro Khanna, Raja and Pramila Jayapal and several others running for Congress.
After a bitter experience in the past, in particular with Bobby Jindal, the community now is seeking accountability and commitment from these candidates.
When around two dozen Indian-Americans from the Silicon Valley held a fund-raiser for Kamala Harris about six months ago, they sought her position on issues related to India and Indian-Americans.
"We are thrilled to see a record-breaking number of Indian Americans got elected for the first time in the US political history," said Prasad Thotakura, president of Indian-American Friendship Council.
