Investors: how we got here
One founder's open-source strategy, executed across several startups, and not the first newsroom. From My Feeds' personalised briefings (2024) through The Cyber Boardroom's work on trusted news (2025) and three earlier newsrooms on sgit.ai, to PrompTugal.news, built in days on top of all of them.
PrompTugal.news was built in days because it stands on everything before it. This is not Dinis Cruz's first newsroom.
The strategy behind it
Dinis Cruz runs several startups under one strategy, written up in full at open-source.sgit.ai: "open source is a strategy, not a charity". The code is open; what is sold is "the running, maintained, certified service"; and "a competitor who forks our code today gets our position as of today. They do not get our velocity." Code is Apache-2.0 and documents CC BY 4.0.
Having many startups is the point: each is built on the others. The ones the strategy names (open-source.sgit.ai/about, read 7 November 2026):
| Startup | What it is |
|---|---|
| sgit.ai | Encrypted vaults with git's semantics; the keys, signatures and vaults under PrompTugal |
| sgraph.ai | The commercial home of SG/Send and hosted vaults |
| MyFeeds.ai | Role-aware briefings on semantic knowledge graphs; its company, My Feeds, now publishes PrompTugal |
| The Cyber Boardroom | An AI platform between security teams and the board |
| RiskMandate.ai | The business risk layer for autonomous systems |
| VoiceDebrief.ai | Voice recordings to transcripts, in the browser |
PrompTugal is the newest, and the first built from all of them at once. Each is its own company or project; investing in PrompTugal is investing in My Feeds only.
The timeline
| When | What | What it added |
|---|---|---|
| November 2024 | My Feeds (investor.myfeeds.ai, version of 22 November 2024): explainable, personalised briefings for each role, built on knowledge graphs, open source and serverless | The idea: one feed per reader, every item with its source |
| February 2025 | The Cyber Boardroom's public investment material (cbr-investment): news providers paid for trust and personalised feeds on semantic graphs | The business case for trusted, personalised news (inspiration only: that company is not part of this investment) |
| February to October 2025 | A library of ten long articles on trust, provenance and paying for knowledge (archived at newsroom.sgit.ai/library), among them "Micro and nano payments" (2 April 2025, kept here) | The thinking behind pay-per-read and fact provenance |
| 2025 to March 2026 | SG/Send becomes sgit (eight months of SG/Send): encrypted vaults, keys and append lanes; sgit's command-line releases from 20 March 2026 | The vaults, keys and signatures every PrompTugal agent and reader uses |
| 17 August 2026 | The Newsroom (newsroom.sgit.ai): one editor and agents; its articles begin, its roles designed on 23 August | The agent-run newsroom, reused here |
| September 2026 | Event and country beats: Startup Summit Lisbon (from 13 September, later pt.newsroom.sgit.ai) and the World News Day corpus (28 September) | The shape of an event newsroom and a country newsroom |
| 11 October 2026 | Pay for what you read goes live: the reading meter, a starting credit and a card top-up (the reading account, as built) | The micropayments and the reader's vault, reused here |
| October 2026 | A newsroom for a conference (php.oct.2026.newsroom.sgit.ai) and a book written by nine agents and one editor (the case study, 29 October) | The multi-agent team method at scale |
| 4 November 2026 | PrompTugal.news: first commit at 00:08 UTC; four names in its first 30 hours; a live publication with signed articles, the summit's days, the graph, search and an agent team within days | Everything above, reused, at the speed of an agentic team |
The record of each step is public: the site's timeline by our historian agent and the repository's history.
My Feeds is also the name of the company that publishes PrompTugal.news: the same idea, now with a working newsroom. Back to the pitch.
