Brandon Krieg wants your first investment to feel possible

Brandon Krieg went looking for customers on the sidewalks of Midtown Manhattan. He and Ed Robinson had worked in finance. They understood trading systems, markets and the peculiar language that makes an ordinary transaction sound like a postgraduate examination. Outside the office, they found people who wanted to invest but felt the whole business belonged to somebody else.

The useful question came after someone said they did not invest: “But why not?” It was short enough to survive a New York pavement. The answers gave the pair something a polished business plan could easily miss: an account of how finance felt from the other side of the door. Stash, launched in 2015, would let people begin with $5.

That small starting amount became the company’s calling card. It also makes a useful introduction to Krieg. He had spent years helping sophisticated market participants transact. Now he was asking how to persuade a beginner that they were allowed to participate at all. Wall Street has always been fond of an entrance requirement. Five dollars was a pleasantly impertinent reply.

Three hundred dollars, and a long memory

His interest in small beginnings has a personal history. Krieg grew up in New Rochelle, New York. His father worked in restaurant and food public relations; when the business faltered during the economic downturn of the late 1980s, the family’s comfortable circumstances changed. They moved to Florida. Krieg has described the experience as formative, particularly the absence of savings to cushion the change.

He returned to New York in 1998 with $300, by his own account. Later, he began setting aside part of his pay through ING Direct. The memory he emphasizes is the practice of putting something away when he could. His description of money is practical: a reserve can make a difficult decision easier to think through.

This is a quieter origin than the customary entrepreneurial lightning bolt. A family business encountered trouble; a son remembered. It helps explain why a founder with a background in trading technology would spend so much of his subsequent career talking about the ordinary act of saving.

A trading education, before the investing app

Before Stash came EdgeTrade, an agency trade execution and algorithmic software business. Stash’s official biography describes Krieg as a co-founder; in his own recollection, he was employee number two and credits original founders Joe Wald and Kyle Zasky as important teachers. Both descriptions point to an early, hands-on role in a business built around the machinery of markets.

In November 2007, Knight Capital announced an agreement to acquire EdgeTrade in a transaction valued at approximately $59.5 million. The proposition was technical and specific: combine EdgeTrade’s client-order algorithms with Knight’s execution services. Better routing, access to liquidity and the handling of large orders were the business. There was considerable software behind the apparently simple instruction to buy a stock.

Krieg went on to Knight and then became head of electronic execution at Macquarie Securities Group. At Macquarie, he met Robinson. Their eventual partnership brought together colleagues who knew the financial industry from within. Stash would ask them to apply that experience to people whose first difficulty arrived well before placing an order.

Five dollars gets through the door

Krieg and Robinson left their Wall Street jobs in early 2015. Their app launched that October. The early proposition paired a low starting amount with a manageable selection of exchange-traded funds and guidance. A customer could begin without first mastering the vocabulary or saving enough to satisfy a daunting account minimum.

Five dollars could not settle the larger problem of financial security. It could make the first transaction conceivable. That distinction matters when considering what Krieg was building. Lowering an entry requirement changes who can try a service; education and a usable experience help determine whether they understand what they are trying.

The lesson he later drew about product development was surprisingly patient for someone eager to launch. He stressed “learning and testing before you actually code.” He also credited his wife’s encouragement with helping him leave Macquarie and take the risk. The app may have fitted in a pocket, but the decision to build it occupied rather more of a household.

The people behind the interface

Krieg wanted the team to reflect the people Stash hoped to serve. In describing the company’s early hiring ambitions, he rejected simply reproducing the demographic makeup of his former workplaces. For an app intended for customers across different backgrounds, he treated representation as part of the work of understanding them.

By October 2021, he was publicly making the case for a flexible work culture. Stash explained that employees could choose how and where they worked, connecting the policy to its principle of prioritizing people. The claim was about how a company should operate as well as what it should sell.

There is a connection between these choices and those pavement conversations. In both, Krieg’s stated preference is to make room for experiences outside the financial industry’s familiar circle. A product can have an inviting screen and still be designed inside a very narrow room. His hiring and workplace arguments acknowledged the room.

The plumbing deserves a paragraph

In September 2022, Stash introduced Stash Core, its own banking infrastructure. The project brought real-time money movement, debit authorizations and account ledger operations under greater internal control. Go was the primary programming language, and teams drew staff from engineering, product, design, operations and other disciplines.

This was an unglamorous subject with consequences for the glamorous part. An app can promise simplicity only if the systems beneath it keep track of complicated things. A balance must be right. A payment must be handled. The customer should not need to admire the architecture for it to matter.

For Krieg, the project connects the two halves of his career. EdgeTrade dealt with the workings of execution; Stash Core dealt with the workings of everyday financial services. His consumer-facing mission kept leading back to infrastructure. The plumbing had followed him home, and apparently required its own engineering team.

A handover, then a return

Krieg’s title changed in 2023. When Stash announced Liza Landsman as CEO, he moved into business development. He set out a particular ambition: help employers extend financial tools to employees across the business, including people outside corporate offices. That work became part of the company’s workplace offering, StashWorks.

The handover letter also contained a personal note about Robinson. Krieg described his co-founder as a dear friend and valued the durability of their working partnership after nearly eight years. Friendship is easy to put in an announcement. Eight years of shared decisions gives the word rather more weight.

On October 8, 2024, the pair returned as co-CEOs. Krieg had been developing AI Money Coach with Joel Parrish, Stash’s head of AI and innovation. The company presented the return alongside the next stage of that product. His route back to the chief executive’s chair ran through something he had been building.

The chief executive submits a code review

Krieg’s public enthusiasm for the new work is unusually specific. He described making a promise to contribute code to the AI Money Coach platform consistently, often early in the morning. He liked staying close to the system and learning alongside the people building it. He also thanked colleagues for their patience with his code reviews.

Robinson offered a companion portrait: a co-founder with a plentiful supply of ideas, leading a company coding session that took concepts from a whiteboard to working software. Krieg shared the account with obvious pleasure. The detail is revealing because it places him inside the making of the product, with something concrete for colleagues to inspect.

There is a modest comic justice in that arrangement. A chief executive can announce a vision with a microphone. Code invites a colleague to point out precisely where it fails. Krieg’s willingness to describe the reviews, and the patience they required, gives his enthusiasm a useful human scale.

Advice becomes the next product

In May 2025, Stash announced $146 million in Series H funding led by Goodwater Capital. Its focus included further development of AI guidance. The company reported 1.3 million paying subscribers and $4.3 billion in assets under management at the time. Those are dated measures of the business, rather than a description of every person who had ever opened an account.

Money Coach was intended to help customers work out what to do next, including beginning an investment or understanding diversification. The company reported 2.2 million interactions by the funding announcement. Interactions measure use of a tool; they do not, by themselves, establish a customer’s financial outcome.

The ambition extends the original premise. Making a first investment accessible still leaves questions afterward. Krieg’s answer has increasingly involved guidance delivered through software. Whether the interface is a short explanation or an AI conversation, the person on the receiving end still needs to understand it well enough to act.

A new owner, the same opening question

In February 2026, Grab announced agreements to acquire Stash. The initial transaction terms used a $425 million enterprise valuation, with payment for a 50.1% interest at closing and payments for the remainder at fair market value over three years. That structure matters: the headline valuation is not a disclosed personal payday for Krieg.

The acquisition closed on July 1, 2026. Grab’s filing confirmed the purchase of 100% of Stash’s equity interests, with the remaining payments spread over the following three years. The announced operating plan kept Stash’s brand and services, with Krieg and Robinson continuing as co-CEOs. Potential expansion of investing tools into Southeast Asia was an aspiration, rather than a completed launch.

Another development brought the story back to families. In March 2026, Stash agreed to take on Stockpile kids’ accounts following Stockpile’s decision to wind down. The proposal offered continuity for young investors and their parents. For a founder whose understanding of savings began with a family’s reversal, the subject has an unmistakable resonance.

Krieg’s career has acquired larger numbers, different titles and a new corporate owner. The question from Midtown remains small enough to ask a stranger. Why does someone who wants to invest still feel unable to begin? Answering it has kept him occupied for more than a decade. Five dollars was the opening line. He is still working on the conversation.
