  • Improve the quality of your spreadsheets and prevent you from making business decisions with incorrect spreadsheets
Bottleneck Detector
Detect the bottlenecks that slow down your file
  • Detect slow worksheets among all the worksheets of your spreadsheet
  • Recognize slow ranges inside your workbook
  • Improve the efficiency of your workbooks by amending any bottlenecks therein

Xavier RIVAL

Scientific Adviser

Xavier is a Research Director for INRIA, head of the ANTIQUE Project-Team of ENS Paris & INRIA & CNRS. He graduated from École Normale Supérieure - Paris.

Xavier works in programming languages and static analysis for the verification of semantic properties of computer programs. His main focus is on abstract interpretation and more specifically on abstractions of linked and dynamically allocated data structures in programs.

He was laureate of an ERC Starting Grant (European Research Council). As part of his research activity as a PI of the ERC MemCAD project, he supported research on the analysis of Spreadsheet Applications. He currently provides scientific guidance to Matrix LEAD.



Tie pursued a PhD in computer science in ENS Paris & INRIA & École Polytechnique; he also has Master's degrees from Mines ParisTech and École Polytechnique.

Tie began learning programming in middle school. After obtaining his master's degree, his work experiences in Total and UBS Investment Bank let him realize that millions of non-programmer professionals are enabled by Excel to do sort of coding, whether knowingly or not. Furthermore, some additional skills and guidance could significantly make easier their work. Since then, he has set the ambition of bringing forth programming insights to end-users to help people code better.

Later, he pursued his PhD entitled "static analysis of spreadsheet applications" under Xavier's supervision in the MemCAD ERC Project group; he implemented the research spreadsheet verification tool AiXL. He then founded Matrix Lead, aiming at empowering end-users with advanced tools from science and technology.
