Black Friday is 29 days away. Here's how SMBs are getting ready, according to new data from
@Symphony_co_ by @Wix:
-More than half of the prep work (56%) happens at night, after the shop closes
-The #1 thing owners ask for help with: deciding what the deal should actually be
-The task they hand off most: writing social media posts
-It's not just retail - coaches, salons and even psychics are preparing, mostly to fill their calendars
-Many have an email campaign written but no customer list to send it to
SMBs aren't short on effort. They're short on time. That's where an AI team comes in.
Taking AI-native development to the next level!
@GabiGrinberg is heading to Japan 🇯🇵 to speak at Architecture Conference 2026, which also features @martinfowler as a keynote speaker! 👏
In his talk, "From Zero to $200M ARR: Behind the Scenes of @Base44's AI-Native Architecture", Gabriel will share how Base44 scaled from a one-person project by @MaorShlomo to $200M ARR in less than two years, while keeping its architecture remarkably simple.
From a single backend and AI-friendly SDK to a world where AI agents write most of the code, he'll share the engineering decisions, architecture, and lessons behind that journey.
Go Gabriel!

Wix cut wasted AI spend by checking whether a skill can actually be executed before offering it to users. Across 756,000+ messages, the gate matched only 59.4% of requested skills as executable — saving 228.8M tokens that would've gone to doomed attempts. Wix Engineering also details runtime checks that caught agent design flaws other tests missed.
Dashboardless products, zero-downtime migrations, lessons from production incidents, two upcoming meetups and more: Here’s what’s inside our latest @Wix Engineering newsletter -
🚩 Our AI Agent’s Design Looked Complete. 3 Runtime Checks Proved It Wrong / @yoavabrahami
Unnecessary APIs, over-engineered types, and an update flow that would leave stale data on screen. Written mostly by the agent itself (!), this account of designing for Wix’s Jay framework shows how human review caught the flaws - with four practical checks for working with AI agents.
🧩 No Dashboard, No Menus: How We Built an Interface Around Intent / Idan Layfer
What happens when an AI agent brings users the UI they need? Explore the architecture behind persistent agent-built interfaces, precise data exchange, and synchronized components - and how a merchant launched a cashback program in 10 minutes.

You’ve read the files. Are you ready for your first "boss fight"? Approach onboarding like an open-world game: trace end-to-end flows, map dependencies, and use AI as your sidekick to prepare for your first high-stakes change.

Matching a skill doesn’t mean a user can use it. Across 756K+ production messages, Helpmate’s executability gate filtered out 59.4% of matched skills, reduced skill context by 90.5%, and saved 228.8M tokens. Read the paper on @arXiv.

Inspired by @GiladBarkan's article "From Autocomplete to Intelligence: How Language Became the Operating System of AI", @Wix's Data Science team created a full-day workshop tailored for the design teams they work with. It covered how LLMs work, how context shapes their outputs, and how AI agents plan, remember, and act. Don't miss this insightful article:
wix.engineering/post/from-au…
AI can write code, use tools, and power autonomous agents. Yet at its core, it does one surprisingly simple thing: predict 🔮 the next word.
So how did autocomplete become intelligence?
In his new article, Gilad Barkan cuts through the weekly noise of new models and frameworks to explain why language became the operating system of AI.
Learn how LLMs actually acquire intelligence, why Transformers and scale changed everything, and where today’s models still fall short. Along the way, he connects ideas from leading thinkers and AI pioneers, including @ylecun, @AndrewYNg, and @harari_yuval.

What does it take to build agentic products on open-weight models?
@ittaiz is speaking at @NVIDIA GTC Berlin 2026! 👏
He'll join a panel exploring why builders are moving to open-weight models, the trade-offs in cost, latency, and quality, and what it takes to run them safely at scale - including what stays on closed models and why. Good luck, Ittai!

An AI skill can match a request perfectly - and still be impossible to execute. @AshkenaziOrtal’s new @arxiv paper explains how @Wix's Helpmate checks account state before skills reach the LLM.
Across 756K+ production messages, this filtered out 59.4% of matched candidates and reduced skill context by 90.5%, saving 228.8M tokens.
At @Reversim Summit 2026, Ortal will explore this approach as part of her talk on designing, routing, and scaling AI skills in production.

From building production AI agents to hiring the engineers who will build what comes next >>> we're proud of @AshkenaziOrtal and Guy Nahum, who are bringing their experience to @Reversim Summit 2026! 👏 👏
🎤 Ortal will explore what happens when one LLM skill becomes hundreds: how to define skills, catch common failures, and route requests to the right capability in a system handling 300K conversations a month. Her talk builds on research co-authored with Vitalii Kloz and Mykhailo Ulianchenko, published on @arXiv.
🎤 Guy will tackle "Hiring Post-Claude": what makes a great developer today, why junior engineers matter, and how @Wix is rethinking hiring and development programs to cultivate the #xEngineer.
Heading to #Reversim? Don't miss their sessions!
Building with AI is getting easier. Understanding why it worked - and making it work again - is the harder part.
On Nov 2, Amir Harel (Symphony by @Wix) will take the stage at the Claude Community meetup at Wix Campus, TLV, to show how a real feature evolved from a successful experiment into a repeatable process.
Good luck, Amir! Details & RSVP:

How do you move critical 🚩 production databases between clusters while millions of users keep using the applications that depend on them?
At @Wix, we needed to solve this to improve reliability: when applications share a database cluster, a problem in one can affect the others.
Bar Shauli shares how she and our Wix Data Infrastructure team built an internal migration service using Kafka and ProxySQL on top of MySQL, allowing databases to move safely between clusters with zero downtime.
From streaming data and handling partitioning challenges to switching live traffic, here's how we make database migrations happen at massive scale-without users noticing.

Components are dead!!!
Agents work better with something completely different - UI Regions.
Read all about the new pattern:
wix.engineering/post/compone…
Components help developers manage complexity. But what happens when AI agents have to navigate the boundaries we created?
Scattered files, slots, and context can force agents to reconstruct a page before they can safely change it. In this article, @yoavabrahami explores how Jay, a new frontend framework, approaches that challenge through regions: keeping markup local and editable while sharing the underlying logic.
You’ll learn how template flattening moves composition from runtime to coding time, how targeted updates keep pages reactive, and how validation and sync preserve local edits as templates evolve. Read here:
