LimeLight

Build your startup community, simplify your complex pitch with AI, and launch your token on a decentralized Solana marketplace.

Inspiration

Great code does not always equal great marketing. We noticed that incredibly talented technical founders often struggle to explain their complex architectures to regular people. They end up isolated, failing to gather the early believers they need to get their ideas off the ground. We realized the ecosystem did not need another cold financial terminal. It needed a community. LimeLight was born from the idea that if we could use AI to simplify the pitch, we could build a true network of innovators supporting each other.

What it does

LimeLight is a Web3 launchpad built on three main pillars:

  • Building the Innovator Network: We replace closed door venture capital gatekeepers with a public discovery feed where builders can connect directly with passionate early believers.
  • Simplifying the Complex: Users simply paste a startup URL into our Creator Studio. We use AI to ingest the complex technical data and translate it into a simple, digestible elevator pitch. We then clone the founder voice to narrate a cinematic video pitch.
  • The Solana Digital Marketplace: Once the pitch is generated, founders can instantly mint a Solana token. Investors can browse the live deal flow and fund projects directly on a decentralized marketplace.

How we built it

We built the frontend creator studio and discovery feed using React and Next.js. The frontend is deployed in an AWS EC2 instance.

For the AI ingestion engine, we utilized Google Gemini API to scrape URLs and generate the simplified problem and solution summaries. Simultaneously, the browser captures the founder's voice signature to perfectly clone their voice using Eleven Labs instant voice clone API. We integrated AWS Bedrock with the Claude Opus 4.6 model to generate the perfect elevator pitch for the project idea, then we pass the text to Eleven Labs text-to-speech API to generate a studio quality audio 30-second elevator pitch. The elevator pitch is then stored in an AWS S3 bucket to be accessed at any time by the frontend.

To pass values to and from the frontend and the Amazon Services, we use serverless AWS Lambda functions to manage REST API calls, AWS Cognito to manage authentication, and an AWS API Gateway to serve as an endpoint for the lambda functions.

Finally, we wrote Solana smart contracts and integrated Phantom Wallet to handle the instant token minting and live marketplace transactions. Solana is deployed in the backend with an EC2 instance.

AWS Services Used:

  • Cognito
  • Bedrock
  • S3
  • API Gateway
  • Lambda
  • EC2

Challenges we ran into

Our biggest challenge was hiding the massive backend latency. Processing AI text, cloning audio, and rendering video takes time. We solved this by forcing parallel execution. While AWS Bedrock summarizes the website in the background, the UI prompts the user to read our teleprompter script to capture their voice signature. By the time they finish speaking, the text generation is already done. Additionally, wiring up the Phantom wallet to automatically pass the public key to the Solana contract without forcing the user to type it out was a huge hurdle we had to overcome to keep the UI clean.

Accomplishments that we're proud of

We are incredibly proud of the Creator Studio user flow. Taking a user from a raw URL to a fully voice cloned, AI summarized, and tokenized Solana asset in under two minutes is a massive technical achievement. The platform completely hides the heavy lifting of Web3 and AI from the user.

What we learned

We learned how to seamlessly bridge heavy AI enterprise tools with Web3 infrastructure. Coordinating parallel asynchronous calls between AWS Bedrock, ElevenLabs, and the Solana blockchain taught us a massive amount about state management and progressive UI loading.

What's next for LimeLight

Right now we have a functioning discovery feed and creator studio. Next, we want to expand the community features by adding public builder profiles and a dedicated portfolio dashboard so early believers can easily manage their startup tokens and interact directly with the founders they back.
