Hey everyone, I know it’s still super early, but I wanted to get this on everyone’s radar! I built a “assistant coach” that can connect to your Sleeper and ESPN leagues and help you make decisions based on you and your league-mates actual rosters!!

Yes, the app was vibecoded… but I’ve put months of real work into it and I actually play fantasy football so I added everything that’s been helpful me over the years. Funnily enough, I came in 5th place but somehow won my league last year, but NOT because I’m some expert lol, because I literally had like six different websites/apps open every weeks and/or posting in Facebook groups asking strangers and friends for sit/start advice or trade advice. With that, I just pieced together the best consensus I could before locking my lineup!

It worked, but it was exhausting, and with a kid on the way I knew I was gonna need a little bit of help this upcoming season. Hence why I built this!

It’s called LeagueVision. And as I mentioned before, it connects to your actual Sleeper/ESPN league and gives you sit/start verdicts with confidence scores, floor and ceiling projections, snap share, opponent rank, and specific risk flags built around your real roster. Not just generic rankings you have to translate yourself.

It also has a trade analyzer with a win/loss verdict and a counter-offer if the deal is lopsided, a lineup optimizer that runs three scenarios so you see your full range of outcomes, and a weekly coaching brief that grades your whole roster and surfaces waiver targets for that week’s matchup.

Again, as mentioned it’s currently live with Sleeper and ESPN integration and Yahoo support coming soon!

Happy to answer any questions and/or feel free to roast me in the comments! 😅

Hey everyone, so I have absolutely ZERO coding background lol but about 3 months ago I started building with Claude Code and I’ve shipped about 11 apps and websites across different projects under my LLC. Some were experiments, some were client builds, and some were for my own ventures!

One of the ones I’m most excited about is called LeagueVision™ and it just went live yesterday!

It’s an AI fantasy football co-manager that connects directly to your real Sleeper or ESPN league and reads your actual roster. Every answer is built around your specific team, not a generic ranking you have to apply yourself.

Here’s what I shipped:

- The sit/start analyzer gives you a verdict with a confidence score and the reasoning behind it. Floor and ceiling projections, snap share, opponent rank, and specific risk factors like injury, game script, and weather.
- The lineup optimizer runs three scenarios, optimistic, realistic, and pessimistic, so you see your range of outcomes instead of one projection pretending to be certain.
- The trade analyzer gives a win/loss verdict, a full value breakdown, and a counter-offer suggestion if the deal is lopsided.
- The weekly coaching brief grades your whole team by position, surfaces your start/sit calls, flags trade targets, and points out waiver pickups based on your actual roster and that week’s matchup.
- The draft assistant handles round by round strategy, who to pick, sleepers, and a needs analysis based on your league settings and roster.
- League history tracks all-time standings, records, head-to-head rivalries, draft grades, and achievements across multiple seasons.

The whole thing is built on React, TypeScript, Supabase, and Vercel. Sleeper and ESPN are live. Yahoo is next.

Claude was basically my entire engineering team for this. If you’re a non-technical founder building with Claude Code, I’m happy to talk about what that process actually looks like because what’s possible right now is kind of wild.

Listen, I understand why they had to implement this but the fact that once your check gets so long that you can’t even send one more message is so frustrating. I used to only encounter this issue after you submit 100 screenshots into one chat, but at least they would still let you talk in and communicating in it. I’d honestly rather the chat just hallucinate half of the message and let me get my hand off document done and just and there and I have to scroll back up and resend another message with everything in it 🤦‍♂️. I hate to say it but OpenAi’s chat length and memory capabilities are LEAGUES BETTER than Anthropic…

Hey everyone! I started First Ventures Collective back in March and it’s grown to 149 members across Reddit and LinkedIn, coming from over 11 countries. We’ve got people building across AI, SaaS, fintech, edtech, consumer apps, and more. A lot of us are vibecoders figuring things out as we go and offering advice along the way, it’s kind of the whole point!

We do monthly Zoom calls where people share what they’re working on and get real feedback from other founders. No pitch decks, no spam, no gatekeeping. As well as have a private Notion HQ with our full member directory.

If that sounds like something you’d be interested in you can find us at r/1stVenturesCollective or search First Ventures Collective on LinkedIn! 😊✌🏽

Hey everyone! We started First Ventures Collective in back March. We’re at 115+ members across Reddit and LinkedIn, coming from over 10 countries, building across AI, SaaS, fintech, edtech, consumer apps, and more.

I kept running into the same problem on Reddit. Great question, five responses from people who watched one YouTube video about dropshipping lol…So I built something a little different.

First Ventures Collective is a global founder community I started in March 2026. We’ve grown to 113 members across Reddit and LinkedIn, coming from over 10 countries and working across fintech, edtech, SaaS, consumer products, AI, skilled trades, and more. Some have built and sold businesses. Some are generating real revenue right now. Some are just starting out. All of them are actually building something.

We run monthly Zoom calls where founders share what they’re working on, get real feedback, and connect directly. No pitch decks required, no spam, no gurus.

If that sounds like what you’re looking for, the subreddit is r/1stVenturesCollective and the LinkedIn group is First Ventures Collective. Both are open now!

I was recently banned this week after weeks of me posting/engaging in there. I have never self promoted, but in my ban message, it says it claims that I did in one of my most recent comments. However, I have screenshots to prove that I didn’t self promote. I’ve messaged the moderators three times but haven’t heard anything… should I just give up?

Hey y’all! Fellow vibe coder here with ZERO actual coding experience. If you have been building with Claude and just winging it like I was, Anthropic has a whole catalog of free certifications and I just finished the three that made the most sense for where I am. Claude Code in Action, the AI Fluency Framework, and the Small Business Guide. A few hours total and completely free.

I have built 11 apps over the last three months including a full personal finance dashboard, a marketplace matching engine, a roommate compatibility scoring system, and a sports league management app, all from my phone with no coding background. After these I actually understand why some of my prompts were working and why others were not.

The full catalog is at anthropic.com/learn. Happy to answer whatever basic questions I can based on what I just learned. 😊✌🏽

Hey y’all! Fellow vibe coder here with ZERO actual coding experience lol. If you have been getting shut down on Reddit every time you ask a basic Claude Code question, just wanted to let you know Anthropic has a free Claude Code certification that took me about an hour and genuinely taught me a lot!! I had no idea half of this existed. I’m about to start the small business guide next. Happy to answer whatever basic questions I can based on what I just learned. 😊✌🏽
