If the idea of a hacker getting access to your bank account is scary, imagine learning that a cybercriminal has hacked into your 401(k).

That’s the kind of anxiety independent robo advisor blooom is guarding against with the introduction of its new Suspicious Activity Alerts feature. The technology continuously monitors user’s 401(k), 403(b), and similar employer-sponsored retirements accounts for withdrawals or loans. If suspicious activity is detected, the solution sends the customer an alert by text message.

“The 401(k) is often a person’s single largest financial asset,” blooom CEO and co-founder Chris Costello said. “bloom is committed to safeguarding your right to retire. Whether it’s exposing and minimizing hidden investment fees or identifying suspicious activity, blooom serves one person: the individual.”

Founded in 2013, blooom demonstrated its robo advisory platform at FinovateFall 2014. Geared specifically for the employer-sponsored retirement market, Blooom provides free 401(k) analysis and charges a flat fee of $10 a month for basic 401(k) management and monitoring – including the Suspicious Activity Alerts feature. Additional 401(k)s can be added for $7.50 per month. Blooom automatically rebalances and adjusts the investment allocation based on the user’s general investment preferences (i.e., stock vs. bond mix) and goals (i.e., time-until-retirement). The company also offers access to human financial professionals to provide planning advice beyond the 401(k).

Blooom’s approach seems to be working. The company announced last fall that it surpassed the $1 billion assets under management milestone, doing so faster than any other independent robo advisor including both Betterment and Wealthfront. In a blog post discussing the milestone, Costello pointed to the application of readily available technology to the often-overlooked world of employer-sponsored retirement accounts as key to blooom’s growth and success.

“There has been ‘off-the-shelf’ technology that has existed for upwards of 10 years that can automate things like the construction of a portfolio allocation, rebalancing a portfolio, and even tax-loss harvesting,” Costello wrote. “But nothing existed to perform this kind of automation when it comes to the 401(k) space – where accounts are spread out over dozens and dozens of different financial institutions. Until now.”

With more than $13 million in total funding, blooom includes QED Investors, Industry Ventures, Commerce Ventures, Allianz Life Insurance, TTV Capital, and Nationwide Insurance among its investors. The company is based in Overland Park, Kansas.

Wealth tech company Blooom announced this week that it has surpassed the $1 billion assets under management milestone.

The Kansas-based company manages employer-sponsored 401(k) and 403bs for “thousands of clients” across the U.S. This comes just 16 months after the company announced it surpassed the $300 million assets under management milestone.

In a blog post, Blooom’s CEO Chris Costello made a point to express the speed at which the company arrived at this milestone. “We also take pride that this Kansas-based company reached the milestone faster than both Betterment or Weathfront – while doing so on a fraction of the capital,” Costello said. He added that he uses these competitors’ achievements to benchmark the company’s own.

Chris Costello, along with the company’s CTO and co-founderRandy AufDerHeide, demoed Blooom at FinovateFall 2014. The company differentiates itself by sticking to its three principles: no more jargon; transparent and fair pricing; and stability and values. The company has raised a total of $13.2 million in funding and was recently featured as one of 10 Kansas City startups to watch in 2017.

Mirror, mirror, on the wall. Which robo-advisor is the fastest growing one of all?

According to monthly SEC filings, no independent robo-advisor had made it to $300 million in assets managed faster than blooom. That the company reached this milestone 20 months after launching—and with less than a fifth of the outside capital raised by its competitors—is all the more impressive. “Most of our growth has been organic, through word of mouth, because our clients—everyday, regular Americans in all 50 states—see how meaningfully we can improve their 401(k)s, cut their hidden fees, and potentially add years in retirement,” said bloom CEO Chris Costello, co-founder.

Founded in 2013 and headquartered in Overland Park, Kansas, blooom demonstrated its technology at FinovateFall 2014, picking up a Best of Show award. The company distinguishes itself from the rest of the robo-advisor pack by focusing on helping investors manage their 401(k)s and other employee-sponsored, defined-contribution pension plans. The platform makes suggestions on asset allocation and portfolio building and steers investors toward lower-cost index funds when practical. For subscribers, the service automatically reviews the portfolio every 90 days to make sure allocations remain in balance and will reduce stock exposure as investors near retirement age. The platform provides free portfolio analysis, and charges $5 a month for accounts under $20,000; $19 a month for accounts between $20,000 and $49,999, and $99 a month for accounts above $500,000.

The company has raised $4 million in funding and includes QED Investors, Commerce Ventures, DST Systems, Gibraltar Ventures, Hyde Park Venture Partners, and UMB Banks among its investors. Named “one in a million” in the Kauffamn Foundation Startup competition last fall, blooom was honored by Employee Benefits News as a Top 50 Benefit Technology Innovator in April. And in March, NPR profiled the robo-advisor as part of a feature on how to help millennials plan for their financial futures when dealing with student debt.
