Decibel

Founders investing in founders. We're an independent VC firm pushing the conventional boundaries of early stage investing.

That’s a 1 with nine zeroes followed!

The rate keeps accelerating. Any tool used by agents directly must be ready for enormous growth in the upcoming months. We started E2B with an idea that agent is our user. Now it’s finally coming true.

Congrats to @chriswandrew, @rbm, & the @ScrunchAI team on their acquisition by @Sitecore 🔥

Websites were built for humans. Now they need to be rewritten for AI agents 🤖

This combination will be a game changer for all and we are excited for what comes next 🚀

notes

The general loop is do good work and then tell people about it. Example (4M views https://t.co/HONnO7qpCW - 1-2 months of work, 2 days of writing)

Sowing:
- doing good work, even in a niche, is interesting to people not in the niche. (example: best pokemon player talking about his craft)
- use [TOOL] for everything, solve and find all problems
- talk to customers who were using [TOOL] inefficiently. realized that there were basic things they werent doing right, and it felt too basic to write but it reached a wide audience because he solved a pain point that customers had but employees maybe wouldnt experience

Reaping:
1. Tell a story. (not simply "how we built x", "how to do x" - more informative/subtle than that)
2. Keep it as simple as possible
3. Don't sell something you don't believe in - if you dont use it, dont write about it.
4. Share secrets - some "real alpha" that you're even a little scared to reveal to competitors

misc:
- Q: How do you write? A: very unstructured... "you have nothing until you have everything", range from
- Q: how much time do you spend writing for work? A: very spiky - one week a lot, one week just heads down engineering, aim for 50-50 sowing-reaping
- Q: how do you make diagrams? A: Claude Design - make 5 different SVGs, make a concept and choose one. diagrams, code snippets. use principles of claude design, give design system and references.
- Q: how much time you reading articles? too much marketing slop. "i read our slack alot".
- Q: getting feedback before posting - use ABCD feedback framework.
- Q: series - Lessons from Claude Code
- make sales collateral
- Q: did u make something more / less popular than expected? -> the skills post

TLDR: Build implicit knowledge, and then make it explicit.

Every founder knows the feeling when they are about to release something fresh and different that can change everything 👀

How can we unlock this power more often? I could think of no better creative mind to tap than Alex Pall (@AlexPallNY), Co-Founder of The Chainsmokers and Mantis VC.

He has become a refreshing new voice in the cyber industry and we’ll be sitting down with him at the RSA Conference to unpack his process for creating new tracks that rise above the noise 🔥

We are excited to open our doors tomorrow to our community of founders and early adopters at the Decibel "Founder Festival" - come by to make new friends, find ideas worth spreading, and leave inspired after our 2+ day event! 🌴

Many thanks to all of our guests of honor and partners who made this event possible 🙏

🎉teamed up with @AISupremacyNews on a massive AI year-in-review:

"2025: The Year the Old Rules Broke" 🌊

"just scale it" — DeepSeek said no
"distribution wins" — Anthropic beat everyone
"america leads open source" — china shipped 9 models, meta shipped 2 🇨🇳

Big week:
⚡ Google ships Gemini 3 Flash + Deep Research API + MCP + Disco
🎨 OpenAI Image 1.5 claims #1 on LM Arena
🧑‍💻 GPT-5.2-Codex drops

No one's sleeping through the holidays 🫠👇

[Jéssica Leão @jesslionness]

Thrilled to announce @DecibelVC is backing @unconvAI and the legendary @NaveenGRao 🏎️

I first met Naveen in 2022 when I had the privilege to back MosaicML – a pioneer in open source AI that first taught the industry to think about proprietary data, specialized models, and training efficiency. Before that, he founded Nervana to rethink AI training from first principles.

Now he's back with his boldest bet yet: AI training is still shackled to the GPU, an architecture designed for graphics, not intelligence. Unconventional is building silicon that runs neural networks on the physics directly – targeting biology-scale efficiency. The human brain runs on 20 watts. We're going to need something closer to that if AI is going to be everywhere.

I cannot imagine a better founder to tackle the most important AI infra problem of our generation.

But more than anything, Naveen is just someone I genuinely love working with. We've closed more Vegas bars at infra conferences than I can count, gotten way too deep on cars and racing, debated endless open source hot takes, and he's gone out of his way to champion rising researchers, new voices in the industry, and even my own growth as a VC.

One-of-one founder. Honored to join this Unconventional journey.

🚨 This week in AI: OpenAI in crisis mode, Claude reclaims coding crown, Anthropic eyeing $300B IPO, and reasoning models now account for 50% of all inference.

A year ago that last stat was near-zero 🤯

Loved this conversation, @GayatriSab! ✨Always a treat to sit down with a friend and talk about where AI is headed and what founders should be thinking about as the landscape shifts.

[Jéssica Leão @jesslionness]

Bangers after bangers this week! @sundarpichai must be having the time of his life.

- Gemini 3: 1501 Elo (highest public rating ever)
- Nano Banana Pro: solved text rendering
- Antigravity IDE: coming for Cursor
- Pricing: +60% over Gemini 2.5 (done racing to the bottom!)

Google's legitimately back. The AI game of thrones continues 👑

Plus: @grok 4.1 held #1 for ONE glorious day before Gemini knocked it back down (lol), @OpenAI shipped GPT-5.1-Codex-Max, @AnthropicAI did a 3-way partnering with @Microsoft + @nvidia & raised $15B

Full breakdown in this week's blog, link 👇

Turns out I love robot dogs too 😂

0/ Reporting live(ish) from the @aiDotEngineer summit 🫡 - here are the most interesting things I heard this morning across @AnthropicAI, @Replit, @zapier, and @Sourcegraph / @AmpCode.

🧵↓

[Jéssica Leão @jesslionness]

Let’s go @aiDotEngineer Day 1! So fun to have a mini @DecibelVC portco meetup with @joshdevonai & @mjamei + after-party with the @sondera_ai team 🔥 🍺

[Jéssica Leão @jesslionness]

Sam Altman: "I don't care if we burn $500M, $5B, or $50B"
SoftBank: sells entire NVIDIA position to fund OpenAI
Markets this week: "wait what are the actual economics here" 📉

🧵↓
1/ The AI infrastructure party started when everyone saw the bill
Leaked: OpenAI spent $5B on Azure inference in H1 2025
Their revenue? Less than half that

Thank you to our friends in Singapore for hosting us this week at the Cyber SG Innovation Summit!

AI is a powerful tool in the cybersecurity sector and is leveraged by both hackers and defenders in rapidly evolving ways

Though we can’t slow down the adoption of AI, but we can collaborate to ensure that the best practices for defending ourselves against novel attacks are shared around the world

We are grateful to Singapore’s Cyber Security Agency for the invitation to participate in this important event.

Startups and security researchers have always played a critical role in modernizing our defenses, and we look forward to working together with your community in the years to come!

[Jon Sakoda @jonsakoda]

We hosted our first event in Miami this week with our founders and early adopter CISOs in the security community. The theme for the event was “changing the game” in the era of AI…

CEOs wants LLMs to be deployed at a fast and furious pace. Every cyber team must evolve their playbooks to keep up with a technology that can’t be slowed down

I am grateful to our special guest Derek Jeter who shared his views on how elite baseball teams play great defense on the field - his advice that transcended sports and security:

**Analyze your opponent closely to learn their methods of attack (where do they usually hit the ball?)

** Position yourself in the right place to increase your odds of success (even a few steps can determine whether you catch the ball)

** Trust your human intuition to make faster decisions on the field (don't rely only on data - trust your gut when it counts)

Thank you to all who joined our event including Tuna Moore (US Cyber Command), @daveaitel (OpenAI), @mattjay (Vulnerable U), and our friends at Daversa and Guidepoint- look forward to our next event together!
