Problems Solved.Results Delivered.

Real projects, real impact. Here's how we've helped companies transform their operations with code and intelligence.

01
SaaS DevelopmentSocial Media / Creator Economy

From 9-to-5 to Launched in 4 Weeks — Funnell.ai

Asif, the founder of Funnell.ai, was stuck in a corporate 9-to-5 while trying to build his escape. He identified a clear gap — creators on X and TikTok lacked unified analytics and actionable insights, forcing them to switch platforms and rely on guesswork. Without a technical co-founder or development team, he risked losing momentum before even launching.

Next.jsSupabaseOpenAIX API

Result

Funnell.ai successfully launched within 4 weeks, enabling Asif to transition from planning to execution. He is now fully focused on distribution and growth, with a solid technical foundation capable of scaling. The product is live, functional, and already positioned to attract creators.

A Business Owner Who Solved His Own Problem — JioDue

The founder of JioDue ran a local installment-based business and struggled with manual EMI tracking using spreadsheets. Monthly operations were chaotic — missed payments, reactive follow-ups, and no clear financial visibility. He recognized that this wasn’t just his problem, but a widespread issue among local business owners.

Next.jsSupabaseTailwind CSSResend

Result

JioDue launched in just 5 weeks and immediately replaced manual processes. The founder now operates with clarity and efficiency, significantly reducing missed EMIs and improving payment tracking. The product is now being shared with other business owners, turning a personal problem into a scalable business opportunity.
