The paperwork landed at UK Companies House in a flurry: three separate share allotments over five weeks, resolutions stripping away pre-emption rights, a share class shuffle. Standard fare for a startup raising money, except that Infiniti Recycling—a Cambridge battery recycler barely two years old—hasn't said a word about how much it's raising, or from whom.
The filings, timestamped late January and mid-February, carry all the hallmarks of fresh capital. Yet as of this writing, the company's funding picture remains maddeningly opaque. For an industry where billion-dollar rounds practically announce themselves, Infiniti's silence is... unusual.
What can be pieced together from public records: a March 2024 pre-seed from Silicon Roundabout Ventures, amount undisclosed. A grant logged at roughly $199,200, surfaced via a Crunchbase widget embedded on the company's own LinkedIn page. And now these filings—corporate breadcrumbs that point toward new money without revealing the size of the loaf.
The Direct Recycling Pitch
Founded on September 13, 2023, Infiniti targets the messy problem of lithium-ion battery waste with what it calls "direct recycling." The process, focused on LFP and NMC chemistries, aims to recover active materials without the energy-intensive shredding that dominates incumbent approaches. CEO Keith Brent leads a team of four co-founders—Nicole Tingle, Lily Jupp, and Maria Carter—with R&D and operations at 256 Cambridge Heath Road in London. LinkedIn pegs the headcount somewhere between two and ten employees, a range so wide it borders on unhelpful.
The company's website touts "carbon-neutral" operations and fully traceable UK supply chains—claims that remain unverified by independent third-party audits or peer-reviewed literature. Infiniti did bring on CFO Matt Oddy late last year, a hire that suggests either growing complexity or growing investor oversight. Or both.
Industry appearances offer another data point: a January webinar on battery recycling, a spot at the Mishcon de Reya Deep Tech Showcase months earlier. The startup is showing up in the right rooms, at least.
When $425 Million Is Just Another Round
Here's where Infiniti's modest corporate housekeeping collides with the reality of its sector. Just weeks before those UK filings, Redwood Materials—the Nevada recycler that has become something of a poster child for the space—closed a $425 million Series E extension. Google joined as a new investor. Valuation: north of $6 billion.
Li-Cycle, another U.S. player, secured a conditional $375 million Department of Energy loan commitment back in early 2023; by late 2024, that figure had swelled to $475 million. Ascend Elements raised $542 million in equity through September 2023. These aren't outliers. They're the new normal.
Market projections reflect the frenzy, though estimates swing wildly depending on who's counting. Grand View Research sized the global lithium-ion battery recycling market at $287 million in 2025, forecasting growth to $2.74 billion by 2033. Fortune Business Insights, using different methodology and scope, projected $5.38 billion in 2025 ballooning to $32.20 billion within a decade. The spread is enormous, but the directional bet is consistent: as EV adoption accelerates and supply chain vulnerabilities become impossible to ignore, investor appetite for recycling infrastructure is heating up.
Against that backdrop, Infiniti's unconfirmed raise—whatever its size—looks almost quaint.
The Information Gap
Silicon Roundabout Ventures remains the only investor Infiniti has publicly named, stemming from that March 2024 pre-seed. The London-based deep-tech firm dropped a hint in an LP-only newsletter about a 2025 "angel round," but the details were redacted, visible only to limited partners. The recent share allotments offer no clarity: no proceeds disclosed, no valuation whispered, no new backers identified.
Third-party aggregators—VCBacked, StartupSeeker—have logged total funding near $823,000 as of late last year, but these are educated guesses stitched together from fragments, not official disclosures. Whether the January and February filings represent a small extension, a meaningful seed round, or something else entirely is anyone's guess.
Perhaps the opacity is strategic. Perhaps it's simply a function of being early-stage in a sector where the winners attract outsize attention and everyone else labors in relative obscurity. Either way, for a market where transparency around funding has become table stakes—where founders trumpet even modest milestones—Infiniti's approach stands out. Whether that's by design or necessity, only the company and its backers know for sure.
Until they say otherwise, the rest of us are left reading tea leaves in Companies House filings.
