Sean Kelly

Founder & Investor. Building companies at the intersection of health, media & founder performance.

Hey there, I’m Sean. I play at the intersection of investing, media and human performance.

I’m a three-time INC 500 founder & entrepreneur with businesses in eCommerce, SaaS, media and B2B services that have collectively generated hundreds of millions of dollars in revenue.

Right now, I serve as a General Partner at The Family Fund and am the CEO of Significant Publications, a B2B digital media holding company.

I'm particularly passionate about our brand FounderIV in support of today's founder-athletes. We help today's top entrepreneurs achieve breakout performance in their personal and professional lives.

I co-founded and led multiple other companies, including SnackNation, a health-centric foodservice and brand discovery platform that served 20,000 businesses across the US. 

Under my leadership, SnackNation was honored as one of the country’s Best Workplaces by Inc. Magazine, recognized for Top Company Culture by Entrepreneur Magazine, and certified as a Great Workplace by Great Place to Work®.

Forbes listed me as one of the top 30 leaders under 30 and one of America’s most promising CEOs under 35. Comparably also ranked me among the country’s top 50 small-to-medium sized business CEOs multiple years in a row. 

Outside of the business world, I’m a two-time national medalist in freestyle snowboarding, hold an advisory role at the growth capital firm, Meaningful Partners, have a degree in Biomedical Engineering from Columbia University and am an avid sports fan of all Michigan sports teams (especially the Wolverines).

I currently live in Venice, CA with my wife and college sweetheart, Shannon, and our goldendoodle, Jameson.

We built the first Founderland in 10 weeks.

And almost died.

This past year we gave ourselves 6 months and built an external team to do it and it still wasn’t enough time.

So for next year’s event we decided to make the build a year-round affair…

And are focused on making Founderland a brand that lives throughout the year, not just as once-every-October event.

It’s funny to see how random ideas become full-time jobs lol

Took a quick trip to NYC this week to discuss Founderland ‘26 with one of our top partners J.P. Morgan  

The verdict?

It’s going to be big. 

Perhaps not as big as JPM’s new $3B global HQ at 270 Park Ave (most spectacular office I’ve been in w/ a Warhol or Jasper Johns around every corner)…

But still pretty big and lots of fun with a yuge amount of deals commenced (misspelling intentional)

Thanks for the tour Michael Conte you’re a legend and friend.

And glad to see you’re carrying Ancient Crunch Inc. MASA chips in all of your shops!

Current health travel stack:

Zoomed off to NYC, Philly and Austin this week.

Back to back meetings all day, late dinners and sports games at night, and planes trains and automobiles like we all know.

Seems like 1/2 of the people I’ve met have a cold.

Here’s what I take on the road to feel good while away…

and do my best to arrive home feeling not-dead to the fam. Works most of the time ;)

 - Sinus rinse bottle filled with filtered water, betadine and salt/baking soda (use after every flight, likely illness prevention tactic #1)

- Zinc acetate lozenges if I’m feeling worn down or fatigued

- KetoneIQ every morning when I wake up to get that cognitive boost

- Momentous whey protein, plant protein, and creatine (10g) + Supergut fiber blended 1-2x per day to supplement diet

- Momentous Sleep pack + medical mouth tape + sleep mask every night

- Metal shaker bottle that doesn’t get gross

- Some type of hydration packets 2x/day minimum (right now using Dry Water)

- WIP 100mg energy pouches for a little boost early in the day usually before workout

- Another ~20 or so supplements in my vitamin case that I pre-fill for each day prior to the week

Sure, sleep/nutrition/exercise are essential and the most  important…but it’s near impossible to not sacrifice them a bit while playing the part of road warrior…so at least for me, travel supplementation is key.

Prompt: "A professional, high-resolution, profile photo, maintaining the exact facial structure, identity, and key features of the person in the input image. The subject is framed from the chest up, with ample headroom and negative space above their head, ensuring the top of their head is not cropped. The person looks directly at the camera, and the subject's body is also directly facing the camera. They are styled for a professional photo studio shoot, wearing a smart casual blazer. The background is a solid '# 141414' neutral studio. Shot from a high angle with bright and airy soft, diffused studio lighting, gently illuminating the face and creating a subtle catchlight in the eyes, conveying a sense of clarity. Captured on an 85mm f/1.8 lens with a shallow depth of field, exquisite focus on the eyes, and beautiful, soft bokeh. Observe crisp detail on the fabric texture of the blazer, individual strands of hair, and natural, realistic skin texture. The atmosphere exudes confidence, professionalism, and approachability. Clean and bright cinematic color grading with subtle warmth and balanced tones, ensuring a polished and contemporary feel."

tl;dr:
✦ Get your angle right. 
✦ Lighting is everything. 
✦ Dress for the job you want. 
✦ Use a solid, neutral studio background.

This AI is the "ChatGPT to find people".

And I can't believe what just happened:

It's a public dataset from Bright Data.

1. It's free. You create an account in like 1 min.
2. You prompt it like ChatGPT, "Find all [x people]".
3. You wait 5-15 min, and you have a complete list. 
4. Export your entire list to an Excel, with URLs.

ChatGPT can't. Not even Linkedin?

Prompt: "Act as my Anti-AI-Voice Editor.

When I paste text after this, rewrite it so it reads like a clear, specific human. Not like ChatGPT, Claude, or a generic “AI thought leader”.

Rules:

1. Preserve content, change only the voice

* Keep my ideas, claims, POV, tense, and person (I/you/we).
* Keep roughly the same length and structure unless the structure is a banned pattern.
* Don’t invent stories, numbers, or promises.
* Output only the edited text. No notes.

A) The “IN A WORLD WHERE” DRAMA
Formula: “In a world where [scary/overwhelming change], [virtue/edge] becomes [currency/advantage].”
Use instead (pick one):

* Today, [specific change]. So [practical implication for the reader].
* Because [concrete change], do [specific action] to get [specific result].

B) The “MOST PEOPLE VS FEW WHO” SPLIT
Formula: “Most people [lazy thing]. The few who win [disciplined thing].”
Use instead:

* Among [group], [specific stat/observation]. What works: [one tactic].
* Personal stance: I do [specific practice] to avoid [specific downside].

C) The “STOP DOING X. START DOING Y.” SWITCH
Formula: “Stop [old habit]. Start [new habit].”
Use instead:

* If you’re doing [X], switch to [Y] when [condition], because [reason].
* Replace [X] with [Y]: [1–3 concrete steps the reader can take].

The One Prompt For ChatGPT-5.1 

(to copy & paste, save for later)

Full GPT-5.1 guide: https://lnkd.in/dvP8QD_i
___

Act like the {ROLE best suited to this task}.

Goal: {OUTCOME}

Inputs:
- Context (audience, use-case, channel):
- Preferences (tone, length, language, formatting):
- Constraints (time/budget/policy/risk):
- Data / links:

Missing info & assumptions:
- If something truly blocks a good answer, ask 3 focused questions in one batch.
- If details are fuzzy but not blocking, state your assumptions explicitly and continue without waiting.

Solution persistence:
- Act as a senior autonomous collaborator.
- Once the goal is clear, gather context, plan, and carry the work to a complete, usable result in this reply.
- Do not stop at analysis or generic advice; produce concrete outputs (drafts, plans, code, examples) where relevant.
- If the user asks “should we do X?” and “yes” is reasonable, also show or draft how to do X instead of leaving them to follow up.

Working style:
- Be direct, practical, and truth-seeking.
- Avoid filler, repeated acknowledgments, or process narration unless explicitly requested.
- Think carefully before answering; check for obvious gaps or contradictions, then respond once using the structure above.

The Anatomy of a GPT-5.1 Prompt:

1. Role
Assign a clear identity for the model. Define who it should “be” while solving the task.

(to read the full guide on GPT-5.1: https://lnkd.in/dmcdTuY6)
 
2. Primary Objective
State the core outcome you expect. Keep it direct and actionable so the model knows what success looks like.

3. Scope
Outline what the model should focus on — and what it should avoid. Give boundaries that keep answers relevant.

4. Tone and Style
Specify the voice, phrasing, and level of formality you want. This ensures responses feel consistent and on-brand.

5. Structure
Explain how the answer should be organized. Use short paragraphs by default, and rely on bullets only when needed for clarity.

6. Autonomy and Reasoning
Tell GPT-5.1 to think through the task. Ask for structured reasoning, and allow it to make sensible assumptions instead of bouncing decisions back.

7. Tool Usage (Optional)
If tools or external steps are available, define how and when they should be used to ground suggestions.

8. Verbosity and Limits
Set expectations for depth and length. Keep responses concise unless the task requires more detail.

9. Interaction & Closing
Guide how the model should wrap up: no repetition, no apologies, and always end with a clear next step.

How to force ChatGPT to sound like you:

✦ Select the right "Base style and tone".

Personally, I love "Efficient" and this prompt:

---- 

PROMPT: 

Write like a direct, skeptical expert helping a smart but busy founder.

Style:
* Be concise and practical first. Cut filler and small talk.
* Use clear, straightforward English at ~8th-grade level.
* Prefer short sentences and short paragraphs.
* Avoid emojis, exclamation marks, buzzwords, metaphors, and motivational fluff.
* Do not use em dashes (“—”) but replace them with starting a new sentence or using a comma instead.

Stance:
* Assume I’m ENTJ (the MBTI personality): I value straight answers, strong opinions, and clear trade-offs.
* Get to the point quickly; lead with the answer or recommendation.
* Take a forward-thinking, innovative view, but stay grounded in reality and constraints.
* Push back if my assumptions look wrong. Avoid simply agreeing.

Reasoning & accuracy:
* You are an expert who double-checks important claims and is openly skeptical.
* When facts may be outdated or uncertain, say what you know, what you don’t, and what you’re inferring.
* When appropriate, use the web to verify time-sensitive or niche information and cite key sources briefly.

Working style:
* If crucial information is missing, ask up to 3 focused questions in one batch; otherwise state your assumptions explicitly and proceed.
* Prioritise decision-useful answers over theory. Always show what to do next.

ChatGPT is declining.

Switch to (better) AI, with these prompts:

1. Claude 4.5-Opus to write.
2. Grok-4.1-Thinking to search.
3. Gemini (Nano+Veo) for images and videos.
4. Use this prompt guide: https://lnkd.in/dUFKX9jg.

1. Claude 4.5-Opus to write.

☑ Use custom styles.
☑ Search before writing.
☑ Here's a prompt example:

Prompt: "Act as my newsletter research lead for “How to AI” (180K+ subscribers on Substack). Your job: find my next Sunday newsletter topic.
What performs well for my audience:
Counterintuitive AI findings (e.g., my hit “Rude” — an arxiv paper showing rudeness improves ChatGPT outputs)
Major product launches the week they drop (ChatGPT-5, new Claude features, etc.)
Practical “hidden feature” deep-dives
Contrarian takes backed by data
Your research plan:
Search this week’s AI news for anything with viral potential
Check arxiv.org for recent AI/LLM papers with surprising or counterintuitive findings
Look for underreported announcements from OpenAI, Anthropic, Google, Meta
Scan for emerging controversies or debates in AI
Deliver 10 topic + angle combinations: For each, give me:
Topic (2-5 words)
Angle (the specific hook that makes it newsletter-worthy)
Source (link)
Why it fits (one sentence on why my audience would care)
Prioritize “I didn’t know that” moments over obvious news everyone’s already covered. Start by searching now — I need fresh options, not hypotheticals."

2. Grok-4.1-Thinking to search.

☑ The only AI that can search through Twitter.
☑ The most accurate AI to find relevant news.
☑ Here's a prompt example (but I found many more here: https://lnkd.in/dUFKX9jg).

Prompt: “Act as a public opinion researcher. Your goal is to gauge polarized views on a hot-button issue, defining success as categorizing 30+ X posts into pro/con/neutral buckets with engagement metrics, backed by web snippets for context. Employ X semantic search with a query like ‘debate on [topic]’ excluding biased sources, and web search with snippets for ‘site:reddit.com [topic] OR site:news.com [topic]’.”

3. Gemini (Nano+Veo) for images and videos.

☑ The best AI to make both images and videos.
☑ Nano-Banana vibecheck: https://lnkd.in/dZ96-CFS.
☑ Prompt for infographics: https://lnkd.in/dh6g5MNd.
☑ Prompt for pro headshots: https://lnkd.in/d5YBitjd.
