Founder profile

Matthew Diakonov, the engineer behind terminator-rs and Mediar's Windows desktop agent.

Most of what surfaces for this name is a one-line tagline pulled from a profile page somewhere. This page is the longer answer: what he co-founded, what he is currently building, the named repositories he has shipped publicly, and the one specific Rust crate that ties Mediar's commercial product to a piece of code anyone can read on GitHub.

Matthew Diakonov is the co-founder and CTO of Mediar.ai, Inc., a San Francisco AI desktop automation company. He builds the Tauri-based Windows desktop agent and co-maintains the open-source Rust executor underneath it, terminator-rs (MIT, currently v0.24.31). His GitHub handle is m13v and his personal site is m13v.com.

The shape of his public footprint, in numbers

The shortest way to understand the gap between the bio-line summary and the actual body of work is to look at what is public on GitHub. He has been shipping under the m13v handle since well before Mediar existed; the count and the spread of languages tell you what kind of engineer is on the other end of a Mediar sales call.

The named projects you can read for yourself

A founder bio is easy to write and hard to verify. Repositories are the opposite. Below are six of his public projects with descriptions pulled from the repos themselves. The first one is the one that matters most for evaluating Mediar; the rest give a sense of the daily output.

The thread that connects them

Almost everything in the list above is some variation on the same idea: get an LLM context from a desktop computer that the LLM did not natively have, then act on it. WhatsApp messages into a model. Browser history into a queryable knowledge base. Screen sessions captured and replayed. Teammate commits summarized so a human reads them in a minute instead of an hour.

The commercial version of that thread is Mediar. A Mediar deployment looks like a Windows host running a Tauri agent, watching a worker do an SAP intake once, and then doing it unattended for the next ten thousand inputs. The accessibility-tree approach (read what the OS exposes, ignore pixels) is the same approach the open-source projects already use; the commercial product just wraps it in audit logs, validation, credit metering, and a no-code workflow editor.

That continuity is why the founder backstory is load-bearing for evaluating the company. The desktop-agent skill set is not something you can hire for in a quarter. You build it across two or three years of throwaway experiments and one or two production rewrites, and you keep publishing the experiments because the next one feeds the last one.

From an open-source recorder to a Fortune 500 production deployment

The arc that ties everything together fits in four hops. The first is the open-source predecessor. The middle two are how that predecessor became a Cargo dependency the commercial product can rely on. The last is what runs unattended on a customer host today.

The hop from Screenpipe to terminator-rs is the most underrated piece. Most companies that start as an open-source project either fold the whole codebase into a closed commercial fork or strip-mine the original repo for talent and let it die. Mediar did the third option: pull the actual execution primitives out into a clean MIT-licensed crate, then make the commercial product a regular consumer of that crate. It is the kind of structural decision that only works if the engineer doing it cares about the code as code, not as a moat.

The largest publicly disclosed production customer for the desktop agent Matthew engineers is LG Electronics. Mediar is also engaged in multiple paid turn-key programs across SAP, banking, and healthcare deployments.

How to actually get a real conversation with him

The most honest way to evaluate someone running an early-stage technical company is to talk to them. Mediar is small enough that founder calls are not theater. The turn-key program (priced at $10K, which converts to runtime credits at $0.75 per minute) is structured so that the first serious conversation about a workflow happens directly with the people who will build and ship the automation.

If you came here because you are evaluating Mediar as a vendor, the call below is the right path; if you came here because you are evaluating him for something else, his personal site at m13v.com has direct contact links.

No SDR layer. You get one of the two co-founders on a real call. Bring a workflow you would otherwise pay UiPath six figures to automate, and we will scope what it would take.

Frequently asked questions

Who is Matthew Diakonov?

Matthew Diakonov is the co-founder and CTO of Mediar.ai, Inc., a San Francisco AI desktop automation company. He is the engineer behind the Tauri-based desktop agent and the Rust executor underneath the commercial product. He goes by m13v on GitHub, where he has 107 public repositories, and his personal site is m13v.com. The other co-founder, Louis Beaumont (CEO), built the open-source predecessor Screenpipe; the two have been shipping together since 2023.

What does he actually build?

Two things, mostly. The first is the desktop agent that ships to Mediar's customer machines: a Tauri app written in Rust that records workflows, talks to the cloud pipeline, and replays them via Windows UI Automation. The second is the open-source Rust crate that does the actual UI work, terminator-rs, published under MIT at github.com/mediar-ai/terminator. Outside Mediar he ships smaller standalone projects roughly once a month, most of them in Rust, Swift, or TypeScript.

Where is he based?

San Francisco. Both Mediar founders are local; the company is headquartered at 945 Market St, Ste 501, San Francisco, CA 94103. The day-to-day involves enough customer time on the phone that the founders' personal mobile numbers are part of the turn-key program.

What is the open-source story?

The Rust executor underneath the commercial Mediar agent is a normal Cargo dependency, not a proprietary blob. If you read the production Cargo.lock you will see a verbatim entry for terminator-rs v0.24.31 (the version current as of this writing). The crate is MIT licensed at github.com/mediar-ai/terminator. Anyone can vendor it, fork it, or build a competing product on top without paying Mediar anything. Matthew co-maintains it.

What did he do before Mediar?

The company traces back to Screenpipe, an open-source desktop intelligence tool the founders shipped in 2023. Screenpipe ran locally on Mac or Windows, captured everything on the screen, OCR'd it, and exposed the result to LLMs as long-running context. It found a developer audience but never converged on a commercial wedge. In mid-2024 the founders pivoted into enterprise workflow automation; the capture and execution layer that grew out of Screenpipe became terminator-rs, and the commercial product became Mediar.

Where does he write or post publicly?

His personal site m13v.com links out to GitHub (m13v), DEV Community (dev.to/m13v, where he has published roughly 18 articles), X/Twitter, Telegram, and email at i@m13v.com. Most of the technical writing is on DEV: pieces on macOS desktop agents, on-device speech-to-text, why local-first AI matters, and what an AI desktop agent actually is. He does not publish on a corporate blog.

Is he a solo founder?

No. Mediar has two co-founders: Louis Beaumont (CEO, built Screenpipe, French-British, GitHub louis030195) and Matthew Diakonov (CTO, GitHub m13v). Both are technical, both write production code, both are on the phone with customers. There are no AEs or dedicated CSMs at the current company size; turn-key program customers get the founders' phone numbers directly.

How do you actually reach him?

If you want to evaluate Mediar specifically, the right path is the turn-key call link at cal.com/team/mediar/mediar-next-day; that gets you 30 minutes with one of the founders without an SDR routing layer. For other inquiries, his personal site m13v.com lists email and other channels. He does not respond to recruiter spam.
