Flux has raised USD $5 million in funding led by Calibrate Ventures, with participation from existing investors True Ventures and Glasswing Ventures.
The money will be used for product development and to expand the company's sales and engineering teams.
Flux sells software that analyses codebases directly rather than relying on ticketing systems and workflow dashboards. It says this approach is intended to give engineering leaders a clearer view of software work as artificial intelligence tools increase the volume of code being produced.
The funding comes as software groups face growing questions about how to track productivity, quality and risk as developers make wider use of AI-assisted coding tools. Flux argues that conventional engineering management tools were built around manually updated systems and do not reflect the pace of change in modern codebases.
Ted Julian, Chief Executive Officer and Founder of Flux, said the company is trying to make code itself the basis for oversight in engineering organisations.
“Flux insights are based on the source of truth, the code, so leaders can lean into AI without flying blind. Every other major business function has a system of record. Engineering needs one that's ready for the Age of AI. We're building that system around the code itself, so leaders can easily and confidently answer the questions that matter most: Are we really getting value from AI? Where could we be doing better? Is our AI transformation creating risk we can't see?” Julian said.
The platform is designed to identify where technical debt is growing, where risk is building up and how teams are collaborating. It also aims to show whether investment in AI tools is changing the balance of engineering work.
Investor view
Calibrate Ventures said it backed Flux for its focus on code-level analysis and its effort to connect engineering activity with broader business measures.
“Engineering leaders don't need more dashboards. They need a direct line into how their code is evolving day to day. Flux's code-first approach gives them exactly that, tying code changes to quality, security, and business impact. We're excited to back Ted and the Flux team,” said Jason Schoettler, Co-Founder and Managing Partner at Calibrate Ventures.
Flux plans to use the new capital to deepen its analysis of complex codebases and add more ways of linking AI-led changes in software development to cost, quality, security and technical debt. It also plans to hire across go-to-market and engineering roles.
One customer cited by Flux is Cobalt, which provides penetration testing as a service. According to Flux, its software helped Cobalt measure a shift in engineering work from maintenance to feature delivery, and the data was used by the customer's finance team in connection with R&D tax credit eligibility.
Mike Garon, Vice President of Engineering at Cobalt, described a broader change in how software teams are working with AI-assisted development tools.
“There is so much enthusiasm now. We've brought playfulness back into building software, and it's paying off. Engineers are exploring ideas freely, then turning the best ones into production-ready capabilities that move the needle for customers,” Garon said.
Flux is based in Boston and positions itself in the engineering intelligence market, a segment that has drawn attention as companies look for better ways to measure output and software health. The rise of generative AI coding tools has added urgency to that search, particularly for engineering leaders under pressure to show returns on AI spending while managing quality and security concerns.
By focusing on the codebase rather than project management records, Flux is targeting a persistent problem in software organisations: the gap between what official workflows show and what developers are actually changing. That gap can matter when companies are trying to assess delivery speed, maintenance burdens or the long-term effect of AI-generated code on system reliability.
The round adds Calibrate Ventures to Flux's investor base alongside True Ventures and Glasswing Ventures, giving the company fresh capital as businesses seek more direct ways to monitor how software is being built.
