(Bloomberg) -- Women’s careers are differentfrom men’s, and their retirement planning should be, too, is Sallie Krawcheck's pitch.

Now Krawcheck, who made her name at Citigroupand Bank of America as one of the top women on Wall Street, hasclosed a hefty new round of funding for her startup robo-adviser,Ellevest.

Founded just over a year ago, Ellevest is an onlineinvesting platform that offers exchange-traded funds to help women save for retirement. Thatdoesn’t mean the fund’s ETFs are somehow better suited towomen, but that Ellevest tailors their portfolios towomen’s needs.

For example, it uses salary curves geared to women,who usually see their highest pay at an earlier age than men andtake more career breaks, which slow wage growth.

With longer life spans, women have different risk profiles,too. Ellevest factors all this in so the portfolios itgenerates better estimate lifetime salaries and how much moneyits clients will need in retirement.

To help them reach their goals, the firm aims for 90percent of annual income in savings before retirement, ratherthan the more typical 50 to 70 percent.

“Forecasting those things out is really important forretirement,” Krawcheck said in an interview.

The new, $34 million round of funding was led by RethinkImpact and included Salesforce Ventures and CreditEase FintechInvestment Fund. Venus Williams and Mohamed A. El-Erian have alsobacked the startup. El-Erian, chief economic adviser of Pimcoparent Allianz, is a Bloomberg View columnist.

Krawcheck, chief executive officer and co-founder ofEllevest, was the chief financial officer and head of globalwealth management at Citigroup before heading up wealthmanagement for Bank of America.

Even with her high-powered resume, it isn’t clearhow scalable a digital money manager for women is.

Other female-focused robo-advisers have struggled, someunsuccessfully. SheCapital was around for only about ayear—though Ellevest itself may have played a part in itsdemise, having launched at around the same time.

Krawcheck said she is confident she can keep up thepace but acknowleged that raising the money wasn’t easy.

She said she could add more features consumers are askingfor, like credit cards and lending, or partner with companiesto give advice or create portfolios for their female employees.

Ellevest charges higher fees than some of the other robos,at 0.5 percent of invested assets, which can help it becomeprofitable with less money under management—but can also deterprice-conscious customers who look to ETFs for low-costinvesting.

Ellevest has grown to just over $50 million in assets undermanagement since launching in November.

For now, the new capital will go toward addingplanners to the platform, something Krawcheck says clientshave been asking for.

Adding people to the digital mix has been a trend this yearamong robo-advisers. Betterment LLC. and Charles Schwab bothlaunched hybrid versions in recent months, pairing thetechnology behind the robo-platform with living, breathingbeings.

Krawcheck said Ellevest will keep working with theclient “to create exactly what she's looking for.”
