What does it look like when someone builds a
company that the market did not ask for but somehow cannot live without?
How do you find the founders who
are solving for a world that has not arrived yet
but is already overdue?
These are not the companies that
came from a slide deck or
a trend report or a conversation
at a conference someone was already going to attend.
They came from people who
had seen something broken for
long enough that they could not
look away from it anymore.
These are the bets we made,
not because the timing was perfect, but because
the people behind them were the
kind you do not get a second chance to back.

$34M
Orronel is building programmable biological circuits that operate like software, allowing researchers and manufacturers to define cellular behavior through a written instruction set rather than years of trial-based genetic experimentation. Their platform compresses the design-to-validation cycle for therapeutic proteins from eighteen months to under six weeks. The underlying architecture treats the cell not as a black box but as an addressable computational substrate, which is a shift so fundamental that it changes who gets to participate in the future of medicine.

Halvr builds terrain-adaptive navigation systems for autonomous vehicles operating in environments where GPS is either absent or actively compromised. Their core software stack uses a combination of passive signal inference and real-time geological mapping to orient machines in underground, contested, and deep-sea conditions. What makes Halvr different is that they are not trying to replace GPS but to make it irrelevant.
Silt
Climate Infrastructure / Carbon Sequestration

Total Raised to Date
$8M
Silt is rethinking how ocean-floor sediment can be used as a long-term carbon sink, working with marine geologists and port authorities to develop a deposition process that is both measurable and verifiable at scale. The science has existed in fragments across decades of oceanographic research, and what Silt has done is assemble it into an industrial process that can be contracted and audited. They are small, precise, and working on something that most people in climate tech have not yet thought to look at.
Fenix Ledger
Financial Infrastructure

Series A

Total Raised to Date
$267M
Fenix Ledger is building the settlement and reconciliation layer for bilateral debt agreements between emerging market governments and their creditors, a process that currently relies on a patchwork of fax machines, PDF contracts, and intermediary banks charging rent on every transaction. Their system brings programmable settlement logic to instruments that have not changed structurally in forty years. Three central banks are already running pilots.
11-11 is a venture fund built on the belief that the most
important companies of the next decade
will come from places and people
that the mainstream investment world has
not yet learned to read correctly.
We back founders who are working on problems so specific and
so technically deep that most investors cannot
evaluate them without asking
someone else first.
The companies we choose
are not the ones
that fit a thesis written at the beginning of the
year and applied to everything
that walks through the door after.
We make bets that feel early because they are early, and we
are comfortable sitting in that uncertainty for longer than most funds are structured to tolerate.
What we bring to a founding team is not a network
deck or a list of portfolio introductions
but a genuine understanding
of the technical and
commercial landscape they are operating inside.
{1} How we decide
23//5
We do not run a scorecard or a committee vote. Every investment decision at 11-11 comes from a genuine conviction that the founder in front of us has seen something real, and our job is to understand what they saw well enough to believe it ourselves.
{2} What we bring
24//6
Capital is the smallest thing we offer. We come in with technical fluency, commercial pattern recognition, and a network built specifically around the kinds of hard problems our companies are trying to solve, not a general-purpose rolodex applied generically to every situation.
{3} Who we back
25//7
We back founders who are closer to researchers than to salespeople, who have spent years inside a problem before deciding to build a company around it, and who are more interested in being right than in being understood quickly by people who have not done the work.
{4} How we stay
26//8
We do not disappear after the wire clears. We are present through the difficult inflection points, the ones that do not make it into the press release, and we measure our value to a company by whether they would call us at an uncomfortable hour on a bad day.
This is our attempt to do something about that.
Every decision at 11-11 traces back to a
person who was willing to put their
name and their judgment on the line for it,
and that accountability is something
we think about seriously.
We are a small team by design because we believe that
the quality of attention a founder receives from their
investors is inversely proportional to how many investments
that investor is trying to manage at once.
The partners at 11-11 have
each spent time on the other side of the table, either building companies,
running technical teams, or working inside
industries that the rest of the
venture world treats as a black box.
That experience is not a credential we list on a website, it is the actual reason a founder
picks up the phone when we call. We are not trying to be the biggest name on your cap table, just
the most useful one.

Nadia came to venture after a decade of operating roles across three continents, most recently as the Chief Strategy Officer of an industrial robotics company that scaled from twelve people to over four hundred during her tenure. She has a particular instinct for founders who are building in markets that do not yet have a consensus name, and she has been right about that instinct more often than most people who have been doing this twice as long.

marcus@eleven.vc
Marcus joined 11-11 from the engineering side, having previously led infrastructure teams at two companies that were redefining what software could do inside physical systems. He is the person in the room who can tell the difference between a technical moat and a technical story, and the portfolio companies that work most closely with him tend to describe that quality as the most valuable thing they did not know they needed.

Henry spent eight years as a deep tech researcher at a national laboratory working on materials at the intersection of biology and computation before leaving to co-found two companies, one of which was acquired and one of which failed in a way he learned more from. He started 11-11 because he kept seeing genuinely important science die at the commercialization gap, and decided that the most useful place he could stand was between the lab and the market.

The best companies we have ever backed made us feel
uncertain before they made us feel certain.
That feeling is something we have learned to trust.

Hard to explain to most investors?
You belong here.
Every submission is read
by a partner.
No exceptions.
Apologies.
my ADHD and this project had a mutual breakup, and I was not the one who initiated it.
The responsiveness part specifically looked me dead in the eyes and said 'not today.'
I tapped out. Fully. Spiritually. Across all screen sizes.
Best,
Aryan
