Marketer who ships apps | B2B SaaS marketing + custom web apps via @digiininja | Building in public | The Addictive Brain

Joined April 2009
I’m 38 and building a SaaS product. Background in neuroscience, with a long-running habit of explaining complex things clearly, now applied to marketing and product. Looking to connect with: • Founders and early-stage builders • People working in AI, SaaS, and startups • Marketers who care about substance over noise • Anyone building in public #letsconnect and hear what you’re working on.

Is it too early to charge for your AI app? If one stranger would pay $9 today, no. Free users tell you what’s nice. Paying users tell you what’s necessary.

Hey @X @grok - my analytics show 4k verified impressions but creator studio dashboard show 937. Why this discrepancy? Which one to trust? @kamilbaranek_ - do you know anything about this?

This is huge. @AnthropicAI just filed for an IPO. #ClaudeAI #IPO #AnthropicIPO
Anthropic just filed for an IPO. $16.3B in H1 revenue, despite an $80.7B net loss driven largely by a financing-related accounting charge. One of the most closely watched AI IPOs is coming.

Getting your first 100K impressions on X as a new builder isn’t easy. Here’s what I’d do: Post 6-8 short originals a day. Reply to bigger accounts in your niche early. Put the best idea in line one. Volume gets you seen. Quality decides who stays.

.@airtelindia - stop calling every day and telling me to take an IPTV connection. I have told you multiple times; I am not interested. How hard it is to get my number off your calling list?

Stop asking marketing to “make it convert” after you build the app. If marketing owns the signup number, they get a say before the first prompt: who it’s for, what the page says and what gets cut. Most apps that don’t convert were never built for a person.

Vibe coders, can you spot the error? I can.
If you're not Vibe Coder and can't spot the error here . Cooke.

A rule I follow when building with AI: Never ship what you haven’t broken yourself. The AI will tell you it works. Your users will tell you the truth. Testing is not extra work. It is the product.

Everyone wants users for their vibe-coded app. Few want the daily work: 🎯 Pick one person with one problem ✍️ Write the landing headline first 📤 Post the build every day 💬 Reply to 20 builders 📩 DM 5 people who’d actually use it

Question for @X and @elonmusk: Premium users can edit posts for 60 minutes, but not replies. Why? Even a 5- to 10-minute edit window on replies would help fix typos. Can you add this feature, @Support?

Economist test: web $59, print $125, web+print $125. 84 of 100 students bought the bundle. Remove the print-only option, and 68 picked web. One decoy flipped the page.

Distribution is what matters at the end.
Lovable doesn’t get you users. Claude Code doesn’t get you users. Cursor doesn’t get you users. A perfect UI doesn’t get you users. Distribution gets you users.

Do hashtags increase reach on @X?

Couldn’t sleep last night. Down with food poisoning. Rest day for me before I jump into X and working on the product.
