Questions & Answers

As answered by people managing StackMail and PropelAI Studio.

What makes your product unique?

PropelAI Studio's answer:

One tool for the entire client workflow: AI proposals, contracts with e-signatures, and invoices that collect payment — including Paystack (card, bank transfer, USSD) for African and emerging markets, alongside Stripe and PayPal. When payment lands, the invoice automatically becomes an official receipt. No stitching together a proposal app, an e-sign tool and an invoicing tool.

How would you describe the primary audience of your product?

PropelAI Studio's answer:

Freelancers, consultants and small agencies (1–10 people) worldwide — especially in Nigeria, Africa and other emerging markets, where clients commonly pay by bank transfer or USSD and USD subscription prices are a real barrier.

What's the story behind your product?

PropelAI Studio's answer:

Built solo from Abuja, Nigeria by Ayorinde Ajayi — a petroleum engineer who spent 5+ years in business development and sales before teaching himself to code. He kept watching talented freelancers lose clients to slow paperwork: slow proposals, unsigned contracts, unpaid invoices. PropelAI Studio is the tool he wished existed — launched on Product Hunt in September 2026.

Which are the primary technologies used for building your product?

PropelAI Studio's answer:

React + TypeScript frontend, Tailwind CSS, Vite, serverless Netlify Functions (Node.js), Supabase (PostgreSQL), Resend for transactional email, Paystack/Stripe/PayPal payment integrations, fast Groq-powered AI generation, and an official Zapier integration.

Who are some of the biggest customers of your product?

PropelAI Studio's answer:

PropelAI Studio is young (launched 2026) and serves individual freelancers and small agencies rather than big brands — designers, writers, consultants and developers across Africa and beyond.

Why should a person choose your product over its competitors?

PropelAI Studio's answer:

PropelAI Studio combines proposals, e-signatures and invoices in one place. The free plan includes 3 AI generations with no card needed. Pro is a founding special at $8/month (₦11,000/month in Nigeria). Invoices can be paid by card, bank transfer or USSD through Paystack, and by Stripe or PayPal.
