pretty well excecuted! congrats on the launch! @shutakamizawa

Really interesting. I’ll definitely give it a try :)

Sorry, because your product involves money, I'm worried about its risks. Is the investment advice it gave me correct? Can you answer my questions?

All the best for the launch @shutakamizawa!

Managing investments is tough, but this looks like it'll make everything so much simpler for me.

Congrats on the launch! Waiting for the crypto integrations like Phantom, Xverse wallet, etc

I love your vision. It feels like you’re solving a problem no one else is tackling head-on! Keep it up!

Congrats on the launch @shutakamizawa ! Wishing you great success!

Lambda revolutionizes investing! 🚀 Unlock deep analysis, optimize your portfolio, and harness AI insights. :)

When the ChatGPT come out, many people say it can be used in many fields including the Financial field. Like, let ChatGPT advise some stocks which can invest. Lambda is a tool like that, so I want to know is there any success example that can be shared about the investment income using this tool?

Very well done. I am excited to try this out, congrats on the launch!

Takamizawa san Hi, I have never experienced such an incredible investment copilot. The UI is intuitive and easy to use, with centralized asset management and rich variation of forecasting models. Hope this app gets the first place in the competition!!

Congrats on the launch! I really like Lambda! Compared to other tools, it feels much easier to use, which is a big plus. I was a bit surprised by your approach to adding portfolios. Using transactions instead of current holdings is definitely the best way to measure portfolio performance. However, I’m not sure individual investors always have a complete track record of their actions. If Lambda allows adding transactions without dates, it probably should be communicated in the interface to avoid confusion. Another improvement you could make is to streamline the information upload process by accepting not just CSVs but any file types. Modern LLMs can parse almost anything, including manual table scraping. Lastly, a quick note of caution, regarding API integration: it is more challenging than it seems (at least for the US market). Even simultaneous use of multiple connection providers like Plaid and Yodlee, won't lead to a good connection success rate. It’s worth keeping in mind and designing the interface to account for potential limitations. Great work overall, I’m excited to see Lambda continue to grow and evolve! 🚀

Lambda is a true assistant in the world of investments, offering professional analysis and smart tools to manage your assets. The application helps to easily track the portfolio, dividends and competently manage risks, which makes the investment process much more efficient and understandable.

Congratulations on the launch! 🚀 It's inspiring to see such innovation. As a soon-to-be graduate in May 2025 from IIT Jodhpur with a strong background in software engineering and problem-solving, I'd love to know if there are any areas where I could potentially contribute to your vision. Wishing you great success!

Super interesting application of AI in the personal finance space! Congrats on the launch Shusuke, can’t wait to see the future iterations of Lambda 🚀

Seamlessly monitoring investments and dividends, coupled with smart risk management, positions this tool as an essential asset for those committed to enhancing their financial strategies. Kudos on developing such an empowering and innovative platform! I'm definitely on board to give it a try!

Nice concept and great implementation, a bit slow on generation to be honest, are you guys upgrading the server to support better performance ?

Thanks for this, I understand that currently it is only supporting US and Japanese stock, any plans for other Asian countries in near future?
