Earnings before interest, tax, depreciation and amortization (EBITDA) are expected to increase by 50-70 percent both this year and next, said Warren, who turns 81 next month.
But he said the contribution from Elevated Careers would be "minuscule" as eHarmony spends heavily to develop the business.
Both employers and job-seekers will likely pay to use the service, although some features could be free.
More than 100 variables will be used to match clients.
Apart from skills and experience, the algorithm will attempt to match job-seekers and employers based on such variables as personality - as on the eHarmony site - as well as work and social and cultural values.
Warren retired from eHarmony in 2007 but came back as CEO after five years to turn around the business, whose growth was slowing in the face of increasing competition.
He cut jobs, bought back shares from Sequoia Capital and slashed the nine-member board to two (now three) - himself and "very close friend" Greg Penner, founder of Madrone Capital and now chairman of Wal-Mart Stores Inc.
A compatible match, it seems.
