Executive Summary

What the company appears to be

Split_it is a self-reported Web3 application built for creating structured, reviewable shared-expense requests using GPT-5.6 assistance and wallet authentication on the Base blockchain. It does not move funds or execute payments.

What changed

The project was submitted as part of the OpenAI 2026 hackathon. The author describes a working prototype with wallet integration, AI-powered expense structuring, and human-reviewed workflows.

Single most important open question

Is there any evidence that this product has been used by users beyond the development team or hackathon participants?

What The Product Actually Is

The description states that Split_it is a GPT-5.6-assisted Web3 application for creating clear, reviewable shared-expense requests with wallet authentication on Base.

Key functional claims:

  • Users can connect a supported Web3 wallet.
  • Authentication is done via Sign-In with Ethereum (SIWE).
  • A user describes an expense in natural language or manually.
  • GPT-5.6 generates a structured split proposal.
  • The proposal is reviewed and confirmed by the user before being created.
  • No funds are moved, executed, or settled by the app.

The product does not:

  • Execute payments
  • Transfer funds
  • Settle debts
  • Manage escrow
  • Perform swaps or investments

Evidence

  • The author states: “Split_it creates reviewable requests only. No funds are moved.”
  • It uses Next.js, React, TypeScript, Wagmi, viem, Supabase, GPT-5.6.
  • The app is deployed on Vercel.

Inference The product is a structured expense request tool, not a payment or settlement system.

Positioning & Claim Evolution

The author positions Split_it as an application that improves upon informal shared expense coordination (e.g., chats, screenshots) by introducing:

  • A structured workflow
  • Natural language input
  • AI assistance for splitting
  • Wallet authentication
  • Review-first design

Evidence

  • The inspiration section says: “Shared expenses are usually coordinated through chats, rough calculations, screenshots, and incomplete context.”
  • The product description states: “turn an informal shared-expense description into a structured request that people can inspect before anything happens.”

Inference Split_it is positioned as a tool for clarity and accountability in group expense coordination, not a financial tool or platform.

Target Customer & ICP

The description does not state the target customer or ideal customer profile (ICP).

Evidence

  • No mention of specific user personas, industries, or use cases.
  • The product is described as useful for “dinner, trip, gift, or group purchase” — but no segmentation.

Inference The ICP appears to be groups or individuals coordinating shared expenses, likely in Web3 contexts where wallet-based authentication is relevant.

Back to contents

Business Model & Pricing Evidence

There is no evidence of a business model or pricing strategy.

Evidence

  • The description does not mention monetization, subscriptions, fees, or any commercial structure.
  • No revenue streams, pricing tiers, or customer acquisition methods are described.

Inference The product appears to be a prototype, not a commercial offering.

Technical & Delivery Signals

The technical stack and delivery approach are detailed in the author’s write-up:

Evidence

  • Built with Next.js, React, TypeScript
  • Wallet connectivity via Wagmi and viem
  • SIWE authentication through Supabase Web3 Auth
  • GPT-5.6 used for structured split proposal generation (server-side)
  • PostgreSQL-backed data storage via Supabase
  • Deployed on Vercel

Inference The product is built with modern Web3 and AI tooling, but it’s a prototype or hackathon project, not a production-grade system.

Back to contents

Traction & Maturity Signals

There is no evidence of traction, adoption, or user engagement beyond the development team.

Evidence

  • Team size: 0
  • No customers, users, or usage metrics are mentioned.
  • The project was submitted to a hackathon.
  • No revenue, ARR, or funding rounds are referenced.

Inference The product is at early prototype stage, with no evidence of real-world use or commercial traction.

Back to contents

Competitive Context

No competitive analysis or market positioning is provided in the description.

Evidence

  • No mention of competitors or similar tools.
  • No indication of market size, addressable market, or competitive landscape.

Inference Split_it may be a novel idea within Web3 expense coordination, but there’s no evidence of existing competition or market validation.

Key Risks & Red Flags

Several risks and red flags are evident from the self-reported description:

  1. No traction or users: The project is described as a hackathon submission with no real-world usage.
  2. AI model dependency: GPT-5.6 is used for generating proposals, but its output is not validated beyond human review — this could be a risk if AI hallucinations are not well controlled.
  3. Limited wallet support: Base Account smart-wallet authentication is deferred due to compatibility issues.
  4. No commercialization plan: No pricing, monetization, or go-to-market strategy is evident.
  5. Unverified claims: The project is self-reported and unverified — no third-party validation.

Inference The product is a conceptual prototype, not a viable commercial offering, with potential risks in AI reliability, wallet compatibility, and lack of traction.

Diligence Questions To Ask The Founders

  1. What is the intended user base for this tool?
  2. How does the team plan to validate the utility of the product beyond the hackathon?
  3. What are the specific use cases or scenarios where this would be valuable?
  4. Is there any plan to move beyond a review-first model, and if so, how will security and authorization be handled?
  5. Are there any plans for monetization or commercialization?
  6. How is the GPT-5.6 output validated beyond human review?
  7. What are the technical limitations of the current wallet support?

Investment/Partnership Verdict

Not evidenced

The description provides no information on:

  • Revenue
  • Customers
  • Traction
  • Valuation
  • Funding rounds
  • Team size or background
  • Market opportunity

This is a self-reported hackathon project, not a commercial entity. The product is described as a prototype with no evidence of real-world usage, adoption, or monetization.

Confidence Low The entire analysis is based on self-reported information and lacks any independent verification or historical data.
