In London for Breakpoint, 14 to 18 November. Bringing something we've been building for people who live, work and invest across borders. Coffee is on me if you want to see it first.

Imo good call skipping the token. We’ve seen the same patterns elsewhere: token launches, hype fades, price drops, backlash follows. Better to focus on the product.
> Updated PFP to me. Not hiding, even behind a cute Pudgy.
> Email dropped on KPUs, so the “horse sh*t word salad” is cleared up.
> The calendar to Xmas is action packed with product updates (details coming).
“Shut up and ship”.
> Interestingly (if you care), we saw no change in product usage. Customer AUM kept growing strongly the last three days.
> Over $10M in USD cashback given since April, when we switched from points/tokens to primarily cash.
> KAST Business is growing nearly 100% MoM (albeit, from a small base). Hot take, it will be on par with consumer by end of 2027.
> Record high numbers of people are now multi-product on KAST.
> No token, means no easy liquidity for the team or investors, everyone locked 🔒 and aligned.
> Never sold anything myself. I actually bought shares this year from earlier investors.
> High conviction we did the right thing by setting aside options, and setting up the SPV for the community.
> Finally: Empathise with those wanting a fast cash out / airdrop; the economic pain people are suffering with multi-decade high rates and inflation is real.
But I must make decisions for the long term.
> Willing to take the short term pain, hate, and multiple death threats. We fled a war zone in Sri Lanka to move to Australia when I was 5, I worked in our family shop since I was 8yo. Grew up with nothing. Failed plenty of time’s myself. I can endure anything you throw at me.
TLDR -
We keep building, and delivering products global citizens need.
The parties are a bit of fun. Life can’t all be too serious. Good marketing in times of the attention economy.
But the financial platform that is @KASTxyz and @KASTbusiness is the main game.
Back to the grind.
Peace out ✌🏾
Whose name is on your domain? Two minutes to check. We've seen it belong to an old agency, and to a web guy who stopped answering emails years ago.

You may not always appreciate my analysis but you can surely appreciate this with a retweet and like.
I will ask nothing more for this artwork analysis on $BTC

One year of building @ReahPlatform from the ground up.
500+ businesses and $600M+ in transactions later, we're still just getting started. Huge thanks to our customers and partners who trusted us and helped shape what Reah is today.
More to come!
One year ago today, we started building @ReahPlatform.
Since then we’ve gone from an idea to $600M+ in transactions processed for 500+ businesses worldwide - one platform to manage banking, treasury, digital assets, payments and cards.
Really proud of this team. On to year 2!
Before you raise your ad budget, compare what the ad account says it got you last month with the quote requests that actually came in.
They won't match. Part of that is Safari: it drops cookies set by JavaScript after 7 days. Someone who clicks your ad today and books a roof survey ten days later often isn't counted.
A Shopify store in Brasschaat, near Antwerp, had the visitors. It was losing the sale after the click: abandoned carts, people who bought once and never came back, and reports that couldn't show what was driving sales.
We rebuilt the store and set up the emails that run after someone leaves or buys:
1. Cart recovery for people who stop before paying
2. A follow-up after the first order
3. A winback email for customers who went quiet
4. Different emails for returning buyers and first-time visitors
From the store's own Shopify numbers, February 2025 to January 2026: conversion rate up 39% on the year before, a returning customer rate of 45.21%, and €277K in total sales, up 34% on 4% fewer sessions.
If your shop gets visitors but not sales, this is where I'd start: go.proofofpixel.agency/x/cal…

I genuinely don't understand how a payment platform like @whop can hold someone's money for almost a WEEK and refuse to let them speak to an actual human being.
Let me explain what's happening.
I used Whop to receive a payment that was supposed to be available INSTANTLY.
Instead, they decided to hold my funds and requested additional business documentation.
Fair enough. I understand that payment platforms have verification procedures.
So I provided the documents they requested.
I was then told that the process would take 1–3 business days.
Fast forward to today.
Almost a week has passed, and I still don't have access to MY OWN MONEY.
But here's where it gets ridiculous.
I've tried contacting their support through both live chat and email.
And every single time, I'm met with what appears to be the same AI-generated responses.
"I understand your frustration..."
But no actual solution. No clear explanation. No human being willing to take responsibility for the situation.
And apparently, I can't even get transferred to a real support agent.
How is that acceptable for a company handling people's money?
We're not talking about a delayed package or a software bug.
We're talking about money that businesses depend on to operate.
Cash flow matters. Bills don't stop coming because a payment processor decides to hold your funds.
I have absolutely no problem complying with legitimate verification requirements.
What I have a problem with is being promised a timeframe, providing everything requested, and then being left in the dark with an AI chatbot repeating the same useless answers.
If a company can hold your money, it should at least have a real human available to explain WHY and WHEN it will be released.
@whop, I don't need another automated apology.
I need three things:
A real human to review my case.
A clear explanation of why my funds are still being held.
An actual date when my money will be released.
Is that really too much to ask from a payment platform?
Builders usually blame price when they lose a job. I'd look at the quote first.
How fast did it go out? Does it say what's included? Is there a name on it?
It's the first piece of your work a customer ever sees.
63% of businesses never replied at all.
that's from a 2024 RevenueHero test of 1,000 companies.
for a roofer or a builder, the quote request is the whole sale. the homeowner probably sent three. my bet: the first one to answer with a time to see the job gets it.
the fix is not a new hire. it's making sure every form lands on a phone someone actually checks.
most of what people want to automate should stay manual.
my test is short. automate it only if it happens often, follows the same steps every time, gets predictable inputs and has a clear right answer.
frequent and low judgment: automate it.
rare and high judgment: keep a person on it.
an AI agent pointed at a messy process doesn't fix it.
leads contacted within the hour are 7x more likely to qualify (Harvard Business Review, 2011).
three steps that get most businesses there:
1. send every form to a phone, not only to an inbox someone checks at 4pm
2. reply within minutes with a real first line, even if it only says when you'll call
3. fill in your own contact form from your phone tonight and time what comes back
step 3 is the one people skip. it's also the one that tells you the truth.
Glad we stepped away from PHP builds a while back. Nothing for us to patch today.
‼️ PHP UPDATE: A public exploit for the leaked PHP flaws is now online, complete with downloadable code, hours before the patch.
Its author, who posts as J4ck3LSyN, says it was recreated and "lab/field tested", and labels one of the two bugs "weaponized (lab)".
The PoC was recently updated, admitting the attack chain it first described does not work.
A separate exploit credited to security firm Calif was shown running commands on a WordPress test site in a video that was briefly posted.
PHP's fix is due at 14:00 UTC today.
Nobody remembers the newsletter. people remember the first email.
For a web3 platform in London, people signed up, then nothing guided them. follow-ups were inconsistent, and the actions that separate an active member from a dormant account weren't tracked cleanly.
the fix was the part after the click: a welcome flow for every new signup, onboarding sequences that walk a member through step by step, segments so each person gets the email that fits where they are, all tied to the CRM.
what made the difference wasn't anything clever, and it wasn't us. it was that every new signup now gets a first email, every time.
if you run on bookings or enquiries, the same logic holds:
1. send something the moment someone enquires
2. walk them to the next step, one email at a time
3. stop sending everyone the same message
i'd start with the first email.
if your enquiries get no first email, this is where i'd start go.proofofpixel.agency/x/cal…
