Martha Dark

Martha Dark is the London-based co-founder and co-executive director of Foxglove, the strategic-litigation non-profit she established in 2019 alongside Cori Crider and Rosa Curling, drawing on prior senior roles as COO at the Open Rights Group and Head of Operations at Reprieve (see Person entry for affiliations and biographical structure). Tracked here as a Voice because the seven-year co-executive-director arc at Foxglove has produced a sustained public register — that algorithmic power exercised by governments and platforms over citizens is, above all, a question of democratic accountability and not a specialist technical matter — carried into UK press, policy venues, and public campaigns through Dark's written and public-facing output alongside the organisation's casework wins. Where Foxglove co-founder Cori Crider anchored the public-law lawyer and convener-strategist voice through the founding years, Dark has anchored the campaigns-and-operations director voice: the framing that builds a popular case for change alongside the legal case.

"Technology is power without proper safeguards"

The foundational register Dark carries across her public output is a democratic-accountability argument: that technology deployed by governments and corporations to make consequential decisions about citizens' lives is an exercise of power, and that the absence of transparency, consultation, or accountability makes it an exercise of unchallengeable power. In the Superrr interview (March 2023) she articulates Foxglove's founding premise directly: "Technology is increasingly used by both governments and private companies to exercise power, without proper safeguards and accountability, and Foxglove aims to counterbalance that power and shift some of it back into the hands of citizens and workers."

The corollary is a transparency argument: that power exercised through opaque automated systems is structurally unchallengeable. In the European AI & Society Fund interview (May 2022) she names this directly: "We can't challenge what we can't see, and it is vital that these systems are developed in the open, with the communities they impact engaged and meaningfully consulted on the use of the systems to ensure community trust in this type of decision making." The framing positions transparency not as a procedural good but as the precondition for democratic accountability: without visibility, the legal and campaigning tools Foxglove deploys cannot engage. Her scale-of-power acknowledgment in the same interview is characteristic: "The power imbalance between big tech and ordinary citizens is huge and creating systemic change will take all of us."

Tech worker solidarity as a strategic check

A second register in Dark's public voice is a tech-worker-power argument rooted in solidarity rather than employment law. In the European AI & Society Fund interview she connects Foxglove's founding purpose directly to this strand: "When Cori, Rosa and I founded Foxglove in 2019 we all felt strongly that supporting tech workers and helping to build tech worker power offered a major strategic check to tech platforms' power." The word "strategic" is load-bearing: the worker-power strand is not an ancillary humanitarian concern but a structural counterweight to platform power in the same frame as the litigation and campaigns work.

Dark's articulation of the specific suppression mechanism appears in the same interview: "Big tech companies like Facebook, Google, Amazon and Uber have spent years perfecting their cultures of fear and secrecy to slow workers' efforts to unionize and speak out against their harmful working conditions," with moderator workers "essentially gagged by overly restrictive NDAs which try to prevent them from even talking to family." On the content-moderation strand, she states in the Superrr interview: "There's no way that the internet can be a safe place until the work conditions of content moderators have improved." In the European AI & Society Fund interview, Dark named the Daniel Motaung case against Facebook and Sama — launched alongside Mercy Mutemi and Nzili & Sumbi Advocates — as the achievement she was "most proud of": "just this week, and alongside an amazing Kenyan lawyer Mercy Mutemi and her firm Nzili and Sumbi Advocates we have supported former Facebook content moderator Daniel Motaung to launch his case."

Health data sovereignty: the Palantir / NHS campaign

Dark's most sustained single-campaign public output is the years-long effort to challenge Palantir's role in UK public health data. The foundational argument appears in her May 2022 interview: "Our NHS holds the largest set of machine-readable health data in the world, making it enormously attractive to tech giants." That attractiveness, in her framing, is not a neutral market fact but the premise for a systematic effort to embed surveillance-infrastructure companies inside national health systems through contract structures that progressively entrench dependence. In the TechPolicy.Press article she authored on 29 May 2026, Dark characterised Palantir as a "fundamentally political company" using a deliberate pattern of free or nominal-cost access contracts — the initial £1 Covid data contract — to gain a commercial foothold, then escalating to a £330m NHS Federated Data Platform deal. The article documented that the Greater Manchester NHS Trust had rejected Palantir's tools as years behind their own, and that the British Medical Journal had found that FDP pilot benefits at Chelsea and Westminster had been "overstated."

The campaign's most visible moment came in March 2026, when a Westminster drop-in Foxglove convened with MPs and peers from Labour, Liberal Democrats, SNP, and Plaid Cymru produced a Financial Times story — illustrated with Dark's image alongside campaign participants — reporting that ministers were exploring triggering the Palantir contract's break clause. Foxglove characterised the moment as "a big win for everyone who has worked on this campaign for the last three years", with an April 2026 parliamentary debate on the FDP contract following.

Platform accountability

Dark's September 2024 article on Foxglove's site — "Is Accountability Finally Coming for Online Platforms?" — argues that the long-standing Big Tech immunity from liability for harms enabled on their services was beginning to erode, reading the August 2024 arrest of Telegram CEO Pavel Durov in Paris, a US Third Circuit ruling making TikTok potentially liable for algorithmic content recommendations, and Brazil's ban on X as a structural shift. The article documents how racist lies posted to Facebook led to murder and how Telegram, X, and Facebook were used in UK far-right violence, to argue that content moderation failures have directly enabled real-world harm at scale. Dark calls for "tough, independent oversight" rather than platform self-regulation, and for legislative change to enforce content-moderation standards proportionate to platform scale.

"Big Tech is too big to exist"

The characteristically blunt end-state vision Dark articulates publicly — that the resolution of the power imbalance requires structural break-up — appears in the Superrr interview when she is asked what winning looks like: "Big Tech is broken up, it's too big to exist is a threat to our societies, our democracies and our workplaces." This is the structural-transformation ambition behind the litigation-and-campaigns work: not only the rolling back of specific algorithms or contracts, but the redistribution of concentrated platform power itself.

Why this is a Voice entry

A Voice entry is created here, rather than additional structure on the Person entry, because Dark's public output is the load-bearing object the corpus needs to track: the Foxglove campaigns-and-operations co-executive voice that has sustained the democratic-accountability framing for algorithmic power across a seven-year arc — from the 2019 founding through the 2020 Home Office and Ofqual wins, the 2022 launch of the Kenyan content-moderator solidarity campaign alongside Daniel Motaung and Mercy Mutemi, the 2022-ongoing health-data-sovereignty campaign against Palantir's NHS contracts, the September 2024 platform-accountability argument, and the May 2026 TechPolicy.Press article naming Palantir's business model as structurally contrary to public procurement principles. The corpus already carries Cori Crider as the Foxglove co-founder voice anchoring the public-law lawyer and convener-strategist register; this entry gives the co-executive director who built and runs the campaigns and operations infrastructure her first Voice entry, closing the Foxglove voice gap the Synthesizer identified. Affiliation, prior employment, and biographical structure are recorded on the linked Person entry per the corpus's Person/Voice split.
