Why We Built Exent
We spent our careers as investment bankers, investors and traders on the institutional side of the market. Here is the gap we saw, and why Exent exists to close it.
Key takeaways
- Exent was built by former investment bankers, professional investors and traders who saw the gap from the inside.
- Professional investors win on systems (risk models, research desks, regime signals), not on instinct.
- Those systems used to sit behind seven-figure minimums, ~1% advisory fees and $24,000+ terminals.
- AI and affordable institutional data make the same discipline possible for one person and one portfolio.
- Exent starts from what you own: your holdings, your risk, your blind spots, explained in plain English.
What we saw from the inside
Before Exent, we worked on the institutional side of the market: in investment banking, in professional investing and on trading desks. We sat where the information arrives first and where every decision runs through a system.
On our side of the screen, nothing was left to a hunch. Every position went through a risk model. We knew how a portfolio behaved in 2008, 2020 and 2022, which holdings moved together, which ones carried the real risk, and when the market backdrop had turned. Teams of analysts read the noise so the decision-makers did not have to.
Then we looked at how most self-directed investors work. Smart, successful people, managing serious money on their own, with a brokerage app that shows prices, a news feed that shows headlines, and a gut feeling. The gap between those two worlds was not talent. It was systems.
Why that gap existed
For decades the gap made economic sense. Institutional data feeds were expensive. A professional terminal costs more than $24,000 a year. Building a risk model meant hiring quants. A good advisor typically charges around 1% of assets every year, and many will not take you on below a minimum balance.
So the tools were built for the people who could pay for them: banks, funds, trading desks. Individual investors got simplified versions, built to keep them trading rather than to help them think.
What changed
Two things happened at once. Institutional-grade market data became affordable through modern APIs, and AI became good enough to do the work of a junior analyst: read filings and news, summarize them with sources, and explain a quantitative result in language a non-specialist can act on.
The math was never the hard part. Correlation matrices, drawdowns, efficient frontiers and stress tests have been textbook finance for fifty years. What was missing was someone to run them on your portfolio, every time it changes, and tell you what the numbers mean. That is now software.
What Exent actually is
Exent is not a chatbot with a ticker box, and it is not another price tracker. It is three systems that work together:
- Portfolio Analysis. Upload a screenshot of your holdings and Exent runs 16 checks on them: where your risk concentrates, which positions overlap, what a crash would have cost you, how you compare with a benchmark matched to your actual risk, and how to get more return for the same risk.
- Market Intelligence. Daily market context with sources, and a regime model that reads liquidity, credit stress, the economic cycle and sentiment to tell you whether the backdrop favors carrying risk or protecting capital.
- Stocks Radar. Exent tracks 4,000+ Wall Street analysts, ranks them by how their past calls actually played out, and surfaces the stocks where the best-rated ones agree.
The calculations are done by quantitative models on real market data. AI does what it is good at: reading, summarizing and explaining. Numbers come from the math, not from a language model guessing.
Why we start from your portfolio
Most investing tools start from the market: here is a stock, here is a chart, here is today’s headline. We think that is backwards. The question that matters is not “is this a good stock?” It is “what does this do to my portfolio?”
Twelve stocks can be one bet if they all move together. A great company can be the wrong addition if you already own it three times through your ETFs. A headline only matters if you are exposed to it. Portfolio trackers show you prices. Exent shows you structure.
What we will never do
Trust is earned in small ways, consistently. These are the lines we hold:
- Promise returns. Track records are shown in the past tense, with sources and with the misses.
- Trade for you. Exent never holds your money or places orders. Your broker stays your broker.
- Sell you products. No commissions, no funds to push, no sales calls.
- Hide the reasoning. Every finding comes with the why behind it, in plain English.
Why this matters
Every cycle the same pattern repeats. Institutions see the risk building and the opportunity forming first, because they have the systems to see it. By the time it reaches a headline, much of the move has happened.
That asymmetry is structural, not malicious. And it is the part technology can fix. The same discipline that used to require a research team and a terminal can now run on the phone in your pocket, on your own holdings, in about a minute.
The 1% had their systems for a century. We are building yours.
