What Undo is building
Undo solves one problem: when software fails, developers usually cannot see what it actually did. Most debugging tools show the code as written. They do not capture the code as executed. That gap is where the hardest bugs live — in runtime states that never appear in logs, in race conditions that vanish when you try to reproduce them, in memory corruptions that leave no trace. Undo's product, LiveRecorder, solves this by recording the full execution history of a running Linux program into a single file. Every instruction, every memory access, every system call — captured as a deterministic record. A developer, or an AI coding agent, can replay that recording, step forward and backward through execution, and inspect any state the program was ever in. Non-reproducible failures become 100% reproducible events. The company sells the technology to engineering teams at networking, database, semiconductor and financial services firms. The AI coding agent angle is the new chapter. AI coding assistants have made that distinction matter more. Teams are now shipping far more code than they can fully understand. Undo argues that an AI agent cannot reliably track down why such code fails unless it can see how the software behaved at runtime. Feed the agent that history, the company says, and it can pinpoint the cause of a bug rather than guess at it. The benchmark they publish: on a set of complex bugs, the latest AI models identified the root cause 38% of the time on their own, a figure that rose to 92% when the models were given Undo's runtime recordings. Undo also says the recordings cut token usage on problems the models could already solve.
Why this matters
Palo Alto Networks is a customer. Suresh Sangiah, its senior vice president of engineering, said the costliest bugs in large codebases live in runtime states that logs do not capture. He said Undo often pinpoints the cause autonomously in minutes. "Undo provides the visibility needed to catch and correct errors before they become an operational problem for our customers," he said. The AI coding wave is the market timing argument. GitHub Copilot, Cursor, and their successors are shipping code faster than any previous toolchain in history. That velocity is creating a new class of bug: the AI-generated bug in AI-generated code, in a codebase no human engineer fully comprehends. The traditional approach of print statements, log files, and GDB breakpoints does not scale to that environment. Undo's runtime recording does, because it does not require the developer to know in advance what to look for. Cambridge Judge Business School research from 2013 put the global cost of software bugs at $316 billion per year. That number is larger now, and will be larger still as AI-generated code becomes the norm in enterprise software. Undo has been building the infrastructure layer for this problem since 2005. The $37M is the moment to commercialise at the scale the problem now demands.

How to actually get hired at Undo
Why applying the normal way doesn't work
There's an ATS, but at Undo, referrals get priority. Your cold application competes with sourced candidates and internal recommendations.

What to show them
Undo's product requires a technically sophisticated sale. The buyer is a VP of Engineering or Director of Platform Engineering at a company with large, complex C/C++ codebases: networking equipment vendors, database companies, semiconductor firms, financial services platform teams. The sales engineer who can take an enterprise engineering leader from "I have never heard of time-travel debugging" to "I need this in my CI pipeline" needs to be a fluent C/C++ developer who can also navigate a long enterprise procurement cycle. Core skills: C or C++ development background, enterprise software sales engineering, Linux debugging familiarity (GDB experience particularly relevant), ability to run live technical demos to engineering directors and VPs, US-based with ability to travel for on-site demos. Proof of work: Take any publicly documented non-reproducible bug from an open-source project (the Linux kernel, PostgreSQL, glibc, or similar). Write a one-page brief on how Undo's LiveRecorder would change the root-cause analysis process for that specific bug: what the recording would capture that current tools miss, how an AI agent would use that recording, and what the conversation with the engineering team lead would look like. Specific bugs, not general claims.

What Undo screens for
Elsewhere Partners is an Austin-based private equity firm that backs growth-stage software companies and has invested in 18 companies across North America, Europe and Israel since 2016. They are not a venture fund. They do not make early-stage bets on unproven technology. They write growth capital into mature products with proven enterprise customers that need distribution infrastructure to reach their next market tier. Their Undo investment is a bet on the commercial opportunity, not the technical novelty. The technology has been proven for years. The question now is: can Undo build the sales and support motion to reach every enterprise engineering team that needs it? The use of funds is explicit and specific: product, support, and sales in the US and Europe. Three distinct hiring tracks. The US emphasis is deliberate — Undo's existing customer base includes US enterprises (Palo Alto Networks, IBM) and Elsewhere Partners is Austin-based with North American portfolio relationships that open commercial doors. Greg Law's quote: "This investment allows us to accelerate at exactly the right moment, embedding Undo into AI workflows, scaling our commercial reach and ensuring we are an essential part of how engineering teams operate."

Don't make these mistakes
Referencing Undo as a startup. It is 21 years old with enterprise customers including Palo Alto Networks. It is a mature product company receiving growth capital, not a seed-stage startup finding product-market fit. Outreach that frames it as an exciting new startup will signal you have not done the research. Frame it as a category-defining technical company that has just received the capital to reach the market it has always deserved.
