Going
Virtual
Cleantech Scaleup
Mission Boston

Limiting carbon emissions, finding new sources
of renewable energy, and efficiently using
resources are among the major climate
challenges of our era. In contending with these
imperatives, cleantech innovators play a key role
in pushing us forward to a sustainable future.
Both Greater Boston and the Netherlands have
taken up this charge and are frontrunners in
preparing for climate change and lowering
emissions. Through an integrated approach, their
companies, knowledge institutions, and
governments uniquely collaborate across sectors
to develop solutions for deployment in their
respective ecosystems.
One component of the Netherlands’ forward
strategy is development of technologies
diminishing resource use. Through innovations in
renewable energy production and energy storage,
grid infrastructure, and IoT solutions for resource
management, Dutch cleantech innovators have
made significant strides in carbon footprint
reduction and creation of more sustainable living
and working environments.
But even Boston and the Netherlands can
improve on their existing models. We cannot
respond only to the challenges within our borders
—we can and should collaborate across
ecosystems to deepen and broaden our impact.
Boston is a top hub for innovation, research, and
technology development in the United States,
and the Netherlands is ready to offer advanced,
highly technological solutions to meet the needs
and complement the latest cleantech innovation
in Boston.
The Netherlands and Boston: a natural fit for a
sustainable future

Caeli provide scities and other local
governments with air quality data
insights at street level so they can
make better policy decisions.
Caeli BV was founded in 2018 and is based in
Amsterdam. We believe that everyone on the
globe has the right to breathe clean air. We are
data, mathematic and development
professionals, and with our algorithm, satellite
data, combined with weather details, we are able
to show air quality on a very high resolution.
With this, cities, countries and governments can
make better policy decisions. Moreover,
inhabitants know exactly where and when air
quality is great for moving to a new city, playing
sports, and just enjoying the outdoors.

ExxFire’s pressureless Cool N2 Gas
Generators are the safer and more
environmentally & healthier
replacement for today’s chemical
and pressurized gas cylinders.
Since the €2.2m seed equity raise in 2015, ExxFire
has: i) secured worldwide licenses for use of the
patents; ii) forged solid commercial relationships
with the major, blue-chip distributors/OEMs (e.g.
Siemens, Johnson Controls-Tyco, Kidde, Nohmi-
Bosai), and iii) successfully developed a product
range of 10 products. As a result, ExxFire has been
selling in 11 European countries, including Germany,
France and the UK, and 9 countries outside Europe,
including India, Singapore and the USA, with
anticipated revenues this year of ca. €600k.
Contracts/LOIs in place indicate booked revenue of
€20m through 2026. Importantly, ExxFire has
continued growing securing new customers/
contracts this year through the Covid-19 lockdown
period.
ExxFire competes in the global fire suppression
market, which grew by 4.8% annually from 2014 to
2019. The target market for ExxFire's products
totalled $4.6 billion in 2019 and is projected to grow
at a compound annual rate (“CAGR”) of 5.3% over the
next seven years.
A key trend driving the fire suppression market’s
growth is the awareness of the environmental
impact. ExxFire is among the greenest of products in
use for industrial fire suppression. The pure nitrogen
gas ExxFire’s generators produce has no Ozone
Depletion Potential (or “ODP”) or Global Warming
Potential (or “GWP”) defined in the Montreal and
Kyoto Protocols measuring how much heat a
greenhouse gas traps in the atmosphere. This is a
significant advantage over most chemical
suppression gasses.
Though significantly cheaper over the life cycle (due
to no maintenance), ExxFire’s products have a higher
upfront cost since ExxFire has outsourced production
of the generators. This constraint restricts the scale
of the business significantly. Several lucrative
prospects and opportunities await reducing the unit
cost of the generators to a market norm. ExxFire is
now seeking growth capital of €5m - €10m to
accelerate its growth and secure its true place in the
market.

Semiotic Labs provides a predictive
maintenance, SaaS-based solution
based on electrical signals that
helps industry reduce downtime,
product discarding, energy waste
and CO2 emissions.
SAM4 is a plug-and-play predictive analytics
solution for critical AC motors and rotating
equipment that monitors industrial assets 24/7. It
consists of sensors and communication hardware
that install inside the motor control cabinet. Our
sensors generate high-frequency current and
voltage data that is sent to our secure online
platform for two types of analysis.
First, machine learning algorithms analyze the
data 24/7 to detect upcoming mechanical and
electrical failures in the motor and the driven
equipment. Second, additional analyses extract
energy consumption, efficiency and performance
insights from this same data. All these results are
directly communicated to the client by our
customer success team and also presented in an
online dashboard for easy visual reference.
Clients may also use the API to integrate SAM4’s
raw data and/or analyses into their existing
CMMS.
Across our installed customer base, SAM4 has
detected over 90% of potential failures up to 5
months in advance. SAM4’s energy and
performance analysis has identified five-figure
savings for multiple individual assets. SAM4 is
currently available for low-voltage motors; pilot
projects for medium-voltage motors and for
induction generators are underway, with
promising initial results.

One of the government’s key objectives is to
improve the assistance provided to Dutch
startups and scale-ups seeking to expand beyond
the Netherlands as well as to foreign startups
seeking to enter the Dutch market. Together with
the Ministry of Economic Affairs and Climate
Policy, RVO.nl, Techleap and several large cities,
the Ministry of Foreign Affairs is developing and
implementing plans to strengthen the
Netherlands’s position as a startup hub.
To help Dutch startups and scale-ups expand
their international presence, the government
organizes trade missions and facilitates their
participation in technology trade shows. In
addition, the Netherlands’ network of embassies
and consulates helps companies integrate in
foreign ecosystems, for example through ‘soft
landing’ programs that focus on opening up local
networks to Dutch startups. The Ministry recently
appointed six startup liaisons on so-called
‘priority hubs’ (the United States, Singapore, the
United Kingdom, France and Germany). In the
United States, our startup liaison will work on a
strong network, together with the Dutch
consulates in New York, Chicago, Miami, San
Francisco, and the Business Support Office in
Houston. Dutch startups and scale-ups will profit
from that network.

startup is different, whether in product,
customer, revenue or other traction. Mentors play
a key role in our community to help NL startups
internationalize and provide startups with a
valuable outside perspective.
We provide direct access to an international
