Tom Charman

former data scientist turned exited founder · building @blokintel · @creativedlab alum, once gave a @tedx talk · helping predict human behavior · bay area based

[Gabriela Naumnik @NaumnikGabriela]

We're going live with @CharmanTom , co-founder of @blokintel , this Wednesday at 1:00 PM EST.

Tom builds agents that simulate how real customers behave inside your product, before you ship anything. He says most product testing tells you what users say, not what they do, and that gap is about to break the way teams build.

We're getting into it live:
- Why discovery is collapsing from months into days
- The 87% fidelity benchmark and what it takes to trust simulated users
- Why regulated industries adopted this first
- What the single builder role means for researchers, designers, and engineers

@AlexAridgides @blokintel @HiggsOlivia Thanks so much for coming out! It was a blast!

[Tom Charman @CharmanTom]

@dimiwonders @Viraj__Acharya @vic_weller SG, let's do it - when works?

@RVAClassic Shook me out of my sleep!

This is going to be wild 🔥

[Blok @blokintel]

On September 4th we launch /BLOK.SIM/01 - part party, part experiment, part glimpse into the future. 150+ AI minds dropped into a simulation: neon corridors, interrogation rooms, UV poker.

Black Mirror IRL 👀

PSA to all the builders out there:

Building is easier than ever. Execution is the hard part.

If you’re working on something competitive, don’t book fake sales calls pretending to be a customer. Spying won’t get you there.

We’re not hard to find. Just harder to catch up to 👍

@blokintel has officially launched out of stealth 🎉

AI coding tools like Cursor and Replit are cranking out code faster than ever, helping developers ship faster. But even with all that acceleration, most teams still have to launch full beta versions or rely on simulation tools to see how new features will actually play out in the wild.

Blok is changing that. Just coming out of stealth, they’re building AI agents that simulate real user personas - so teams can test how people will actually use their product before pushing code live. Pretty powerful unlock for anyone building apps.

Shout out to @charmantom, @HiggsOlivia and the whole Blok team. We're proud to back them alongside @MaCVentureCap, @ProtagonistXYZ, @RackhouseVC and @weekendfund.

@finstratmgmt @blokintel @CharmanTom @HiggsOlivia @MaCVentureCap @finstratmgmt, congrats to the @blokintel team. AI-powered product experimentation is exactly what B2B companies need for faster, data-driven innovation.

[FinStrat Management @finstratmgmt]

Fantastic job to @blokintel, led by @CharmanTom & @HiggsOlivia on their $5M seed round! @MaCVentureCap led the round with participation from angels. This will help build their AI agents to improve product experimentation & expand operations. #seedfunding #AI #startup

[Tom Charman @CharmanTom]

@blokintel @MaCVentureCap @ProtagonistXYZ If you're shipping features into the unknown - and want to test, learn, and move faster book a demo. We’ll show you how Blok works and spin up a custom simulation for your product.

[Tom Charman @CharmanTom]

Excited to announce @blokintel along with $7.5m in funding led by @MaCVentureCap and @ProtagonistXYZ to help product teams move faster, with fewer mistakes - and a lot less guesswork.

So what have we been building, and how can you try it out 🧵👇?

[Tom Charman @CharmanTom]

@blokintel @MaCVentureCap @ProtagonistXYZ Product, design, and growth teams are already using Blok to:

- Predict conversion lift from design changes
- Compare control vs. variant flows before launch
- Simulate friction points for different personas
- Ship faster with fewer costly mistakes

👋 Meet Blok

📍 HQ: San Francisco, California

👥 Leadership: Tom Charman (@CharmanTom) and Olivia Higgs (@HiggsOlivia)

🌐 Website: https://t.co/AG7BQrhOzr

🚀 Vision & Opportunity: Blok is an AI-powered platform that helps product teams make better decisions by simulating product experiments with synthetic users. By predicting how real users will react to new features before any code is written, Blok enables teams to validate ideas, prioritize what matters most, and build with confidence without relying on gut feelings or interrupting actual users.

💸 Round: Pre-Seed

[Rackhouse Venture Capital @RackhouseVC]

Congrats to an incredible team of serial entrepreneurs @CharmanTom and @HiggsOlivia on Blok coming out of Stealth! 🥳

Blok is a simulation environment for digital products. Instead of waiting weeks to A/B test with real users or launch full Beta versions of apps, teams can test changes in hours, using AI-powered simulated users that behave like the real thing.
