Calculeaf
The Next Generation of Engineering Calculations
About
Calculeaf offers a cloud-based engineering and scientific calculation platform designed for engineers, technical professionals, students, and organisations that need a modern alternative to spreadsheet-based workflows and legacy calculation software.
The platform provides tools for creating, editing, and managing structured calculation worksheets that combine mathematical equations, text, units, tables, and engineering logic in a clear and auditable format. Users can perform engineering calculations, scientific analysis, design verification, and technical documentation directly within a web browser without installing desktop software.
Key services and features include:
- Cloud-based engineering calculation worksheets
- Mathematical and scientific computation tools
- Unit-aware calculations and equation solving
- Technical documentation and report generation
- Reusable engineering templates and calculation libraries
- Collaboration and sharing features for teams and organisations
- AI-assisted calculation and workflow support
- Secure online storage and management of engineering calculations
- Educational and training resources for engineering and STEM users
- Subscription-based access to premium platform features
Calculeaf is intended for use across industries such as mechanical engineering, civil engineering, process engineering, energy, manufacturing, research, and education. The platform helps users improve calculation accuracy, standardisation, traceability, and productivity compared to traditional spreadsheets or disconnected calculation methods.

Build a Public Voteable Roadmap So Customers Co-Create the Product With You
Monarch uses ProductBoard to run a fully public, voteable roadmap any user can access from the settings menu. Beyond feature prioritization, the system lets the team reach out directly to voters of a specific feature and walk a clickable prototype past them before any full build begins. This tight feedback loop means fewer wasted iterations and a customer base that feels invested in the product's direction.
I went to Reddit, I checked the subreddit of notion and search for keywords like sheets, Google sheets, excel, CSV — all related keywords to what I was trying to build and validate — and I found a lot of people trying to export the information from notion into sheets.
Validate by searching Reddit for demand before writing a line of code
When Notion released their official API, Leandro spotted a gap but didn't assume demand existed. He went straight to Reddit and searched problem-adjacent keywords to confirm real user pain before committing to build anything.
There's a play for whatever you're stuck on.
