Free calculators and decision tools for startup founders and CTOs. MVP cost estimator, burn rate calculator, build vs buy analyser and more.

Hello Product Hunt community! 👋 I’m Hammad, founder of TechTek.io. I’ve spent the last 20 years in the engine rooms of global tech giants like the BBC, Booking.com, TUI, and Sainsbury's. In those two decades, I witnessed a recurring pattern: brilliant startup ideas dying not because of a lack of vision, but because of a lack of technical judgment. Early-stage founders are often forced to make high-stakes architectural decisions in a Decision Fog: Is this AI agent actually feasible or just a token-burning liability? Should we build this feature from scratch or buy off-the-shelf? How long will our runway actually last with this specific tech stack? Most "calculators" out there use outdated benchmarks or are just disguised "Contact Us" forms. I wanted to change that. I’ve codified the "Corporate Scars" and engineering logic I used at global scale into the TechTek Founder Suite—four free, logic-based tools to help you move from "Guessing" to "Engineering." Inside the Suite: AI-Agent Estimator: Feasibility and infrastructure cost analysis for the agentic era. MVP Cost Estimator: Logic-based budgeting for investor-ready builds. Burn Rate Visualizer: Seeing how your tech choices impact your survival. Build-vs-Buy Analyser: Identifying what is core IP and what is a commodity. We build on an "Opinionated Stack" because we believe speed and scalability shouldn't be a trade-off. Our goal is to help startups ship products that are ready for Series A technical due diligence from Day 1. I’d love to get your feedback on the logic behind these tools. To the founders and CTOs here: What is the one technical "hidden cost" that surprised you most during your build? I’ll be here all day to answer questions! 🚀

Would love to see a runway scenario planner that lets you model multiple hiring sequences at once, showing how adding two engineers in month 3 vs month 6 changes your cash out date. That kind of side by side comparison would make this way more useful for sequencing decisions.

Honestly the burn rate calculator is super straightforward, way nicer than the spreadsheet hack I was using before. Kinda wish more tools like this just existed when I started out.
