SharePay introductionMy name is Zeejah and I m currently building SharePay, a fintech platform designed to make shared payments and repayment agreements easier to manage. The idea came from a personal experience. I booked a trip with friends and paid upfront, then had to chase everyone to pay me back. One person never paid and it made the situation awkward. I realised this happens constantly between friends, groups and even small businesses with customers. SharePay solves this with two core features: SharePay Split allows users to split payments before a transaction is completed, so one person doesn t have to pay upfront and chase everyone later. SharePay Promise allows individuals and businesses to create structured repayment agreements with clear terms, repayment schedules and automated reminders. The goal is to remove the awkwardness of chasing money and create accountability around repayments. We ve built the MVP and validated demand through surveys and early feedback. Right now I m focusing on refining the B2B version of Promise so businesses can use it as a flexible invoicing and instalment payment tool. I d love feedback on: The product positioning The B2B invoicing / instalment use case Go to market strategies for early users Potential integrations with platforms where people already owe money (marketplaces, service platforms, etc).

ProblemHunt

⚡ 5 New Problems to Build a Startup | ProblemHunt

A 3-year search for a simple tool to track both personal and business finances in one place. Nothing fits.
Website owners constantly need minor edits in the admin panel. They are forced to pay specialists for 5-minute tasks. We need an AI agent that does this on command in the browser.
An indie hacker spends 20-30 hours manually cold launching each new product in directories, Reddit, and blogs. There is no tool that fully automates this and proves its effectiveness.
A freelancer often loses in proposal competitions due to the inability to quickly create personalized and visual website concepts for each job order.
A Telegram channel owner is losing their audience without understanding the reasons for unsubscriptions. There is no simple tool for automatically collecting feedback from departed subscribers.
