[TL/DR: Proof is excited to welcome Bill Guinan as our new head of sales! Instead of giving you the bullet points of his bio in a typical dry fashion, we decided to … well … do this ;]
Today we are launching soundproof, a podcast for fans of the Proof blog who think it…
Everything is humming at Proof. Our recent wave of new clients have continued to ramp up, and as a result this past quarter was our best ever across all metrics — volume and notional traded, revenue, etc. Our next algo release (into the Close) is right on the…
[TL:DR] We develop a new metric for evaluating predictions of closing auction sizes for US equities…
Our sixth year is off to a great start with continued growth as many major new clients went live this quarter. Operationally, things are running smoothly, and we deployed significant new technology features to accommodate all the needs of this new wave of…
There are many lessons to draw from Netflix’s “Squid Game: The Challenge,” a reality competition show. The most important — that capitalism subsumes even its most violent critiques? That satire is impossible in America? That someone at Netflix over-bought…
I cannot believe that it has been five years since we started Proof! What’s pretty cool is everything we wrote in that original announcement blog post is still true to this day. This has been an incredible, once-in-a-lifetime experience. I feel immensely…
It takes a certain amount of hubris to write a blog. Ideally, just a pinch. Enough to imagine that your words can matter or…
TL/DR: Proof has recently launched our third algo. Like our flagship Proof algo, the…
This summer Proof was humming on all cylinders, launching exciting new technology and research initiatives and celebrating major successes on the sales front (please see below under Major Updates). We seem to have finally entered a phase of the company where we…
There is something I have to get out of the way up front. I can’t make it all the way through the SEC’s rule proposal on brokers’ use of “Predictive Data Analytics” without writing dad jokes…
From a sales perspective, Q2 was by far the most exciting quarter in the history of Proof! We saw a surge in new client interest, and our pipeline of asset managers currently going through our onboarding process ballooned from ~5 firms to more than 20. In some…
TL/DR: We submitted a comment letter to the SEC on the recent proposal concerning tick sizes, access fees, and adding odd lot information to the SIPs. While we…
It comes with the territory of running a startup that some quarters will be exciting, some will be disappointing, and some will be a grind. The last quarter of 2022 was exciting: we successfully completed a fundraise, went live with some major new clients, and…
We’ve all heard the buzzworthy stats on diversity. And I think, for the most part, it’s now widely accepted that there are merits of having a diverse workforce. Or at least people believe in it enough (or believe in the optics of it enough) to use the words “diversity, equity…
Payment For Order Flow, or PFOF as it is lovingly called, has become a controversial subject in retail trading. Advocates say it produces better prices for retail investors, while opponents lament the conflicts of interest it creates…
It has been a wild four years since Allison and I started Proof. In preparing to write this post, I looked back through our initial announcement as well as our 1, 2, and 3 year updates. We have certainly come a long way!
This time of year, the phrase “woman-owned business” conjures images of soft knitted scarfs, ethically sourced coffee grounds, and the gift card you always receive from your Aunt Carol. We read that label as a communication of values: either the values…
October is domestic violence awareness month, and I annually struggle with what to do about this. It’s not a topic where I can be a dispassionate intellectual, as domestic abuse has deeply affected people close to me. But sadly, at least in…
