Six months is not a long time in the health tech industry.
It’s not enough time to solve air pollution, rebuild cities, or undo decades of environmental harm. But in a startup, six months can be transformative. It can be the difference between an idea and an engine, between early traction and real momentum.
When I first interviewed Louise Thomas, co-founder and CEO of Air Aware Labs, earlier this year, the company was still in an intense phase. By the time we reconnected, Air Aware Labs had shipped major technical upgrades to its flagship app, AirTrack. They had expanded their team globally, securing new partnerships, gaining international visibility, and moving significantly forward on their investment raise.
What stood out the most wasn’t just growth in numbers or features. Rather, it was the clarity. A clear sense of leadership and a clearer understanding of what it takes to build a science-driven company in public.
This conversation with Louise became an insight into what acceleration really looks like in climate and health technology with sustained and compounding progress.
Stepping into Public Leadership
Louise hadn’t necessarily set out to become a public-facing founder. That role emerged organically, driven by urgency as well as ambition.
“I didn’t particularly choose to do anything quite so public,” she mentioned. “But awareness needs to be raised about air pollution. So I feel like I have to take all opportunities.”
As Air Aware Labs has grown, Louise has increasingly appeared in podcasts, international reports, conferences, and leadership forums. Rather than seeing this as a branding alone, she views public engagement as infrastructure for resilience. Early-stage startups face constant uncertainty. Not everyone understands or supports what you’re building, especially in a space as under-communicated as air pollution. Finding a community that does care becomes essential. That community includes customers in addition to all the people who help you keep going.
Platforms like LinkedIn, she noted, have become unexpectedly powerful tools. They allow founders to connect globally, share progress, and build trust without massive resources. And in air pollution, which is still a relatively small but deeply motivated field, those connections feel tangible.
Recognition, Awards, and Learning to Be Selective
In the past six months, Air Aware Labs has been nominated across five categories at the Tech Trailblazers Awards, including Diversity. They won in two categories: Sustainable Tech and Firestarter, the latter recognizing high-impact startups without venture capital backing. The awards marked an important external validation of the company’s technical direction and mission-driven growth. These recognitions matter while Louise approaches them with nuance.
In the startup world, not all awards are equal. Some offer genuine visibility and validation. Others are little more than pay-to-play marketing exercises. “When we started, we applied for a lot of awards,” she said. “You’re trying to get coverage, to get people to know your brand. But over time, you realize you need to be selective.”
What makes recognition meaningful is alignment, when evaluators truly understand what you’re doing and why it matters. When an award reflects something you really are trailblazing in, that’s different since it feels validating. For early founders, this discernment is part of maturity: learning where to invest time, energy, and credibility.
The Engineering Leap: From Data to Decisions
The most dramatic transformation at Air Aware Labs over the last few months has been technical.
Since June, the company’s CTO has been working full-time on the product, unlocking a level of progress that simply wasn’t possible before. The team made a strategic decision to rebuild core components of AirTrack’s data infrastructure, specifically to support something users had been asking for consistently: actionable, cleaner-route recommendations.
Users didn’t want to be told that a route was “bad” or “medium.” They wanted to know which route to take instead. That meant the existing data wasn’t enough.
Air Aware Labs began developing its own hyperlocal air pollution models using machine learning, supported by the UK’s Hartree Centre, one of the country’s leading AI research institutions. These models allowed the team to dynamically optimize routes based on both location and time. The result: a cleaner-route optimizer that Louise describes as world-leading. Unlike static AQI overlays, AirTrack now actively computes lower-exposure paths in real time. It’s the difference between information and intervention.
Beyond product development, the last few months have also marked a shift toward formal scientific and public accountability. Since we spoke for the interview, Air Aware Labs released its annual report and shared a pre-print of its first academic paper, outlining the methodology and evidence behind its approach (Access both here). Making both technical performance and learning publicly accessible reflects the company’s commitment to transparency in a space where trust and verification matter deeply.
From Activities to 24-Hour Exposure Awareness
After launching the cleaner routes feature in September, the team turned to another hard problem: background exposure tracking.
Doctors and users alike had been asking for a more complete picture, one that didn’t rely on manually starting activities. Air pollution exposure doesn’t only happen during workouts; it accumulates all day.
AirTrack is now testing features that passively estimate exposure across a full 24-hour cycle, identifying whether users are walking, running, on a bus, or indoors, and calculating exposure accordingly.
This shift, from episodic tracking to continuous understanding, marks a significant evolution in how individuals can engage with their air health.
“If I look back,” Louise said, “that’s only about five months of work. It’s amazing how much we’ve done.”
Stress-Testing in the Real World
AirTrack isn’t being tested only in labs or simulations. It’s increasingly used in demanding real-world environments, from dense urban commuting to extreme endurance events like Project Salt Run.
These conditions push the product to its limits and reveal what truly works.
Stress-testing, Louise explained, isn’t just about performance. It’s about credibility. If the app works under extreme variability, it’s far more likely to work for everyday users.
Building a Global Team Intentionally
Air Aware Labs’ growth hasn’t been confined to the UK. While the founding team is UK-based, the company’s first hire is originally from Uruguay, bringing valuable connections and cultural fluency in Latin American markets. The software development team is based in the Philippines, contributing not only technical expertise but also real-world user feedback from a different environmental context.
Advisors, too, are becoming increasingly global, with future plans to expand expertise across India, China, Southeast Asia, and the US.
“Cultural understanding matters,” Louise emphasized. “You can’t just copy-paste a product into a new country.” This internationalism has been foundational to scaling an air quality solution that’s meant to work everywhere.
Fundraising: Telling One Story to Many Audiences
Fundraising remains one of the most demanding parts of startup life, and Air Aware Labs’ current raise, now about two-thirds committed, has come with important lessons. One of the most difficult challenges has been learning how differently investors evaluate early-stage climate companies.
Some investors are primarily motivated by health outcomes and social impact, while others focus almost entirely on financial upside and scalability. Navigating these differences requires clarity, not constant reinvention. Rather than tailoring an entirely different story for each audience, the team has learned to anchor every conversation around a single, sharp narrative that can resonate across perspectives.
Participation in an accelerator this fall played a key role in refining that message, particularly in understanding the contrast between European and US investment cultures. European investors often place heavy emphasis on early revenue and detailed financials, while US investors tend to prioritize long-term vision, market size, and the strength of the founding team. There is no universally perfect pitch, only alignment. Over time, Air Aware Labs has learned to focus its energy on investors who genuinely understand and support what the company is trying to build.
What Success at Scale Really Looks Like
For Air Aware Labs, success by the end of 2026 isn’t defined by the number of new features shipped or incremental product updates. The real indicator will be adoption at scale: when air quality data is no longer something users have to seek out, but something embedded seamlessly into everyday systems. This includes partnerships with wearable technology companies, healthcare providers, bike-share programs, and respiratory clinics that integrate air quality insights directly into people’s routines. Product development follows a relatively predictable path; market adoption does not. Yet it is at this intersection, where data becomes infrastructure, that impact begins to multiply.
Being a Female Founder – Changing the Default
Louise speaks openly about the gender dynamics she has observed in tech and climate innovation. While explicit discrimination is increasingly uncommon, subtle patterns persist.
Women founders are often questioned on how they will reduce risk, while men are encouraged to articulate how they will scale and maximize upside. Despite strong evidence that women-led startups perform well, women still receive only a small fraction of global venture capital funding. Changing this reality requires more than individual resilience. It calls for structural shifts: more women in investment roles, broader representation in decision-making, and a cultural redefinition of who is expected to build and lead companies in the first place.
Advice for the Next Generation
When I asked Louise what guidance she would offer young women and students aspiring to careers in science, engineering, or environmental innovation, her response centered on confidence: confidence in your work, in its importance, and in your right to contribute to the conversation. Setbacks are inevitable, and doubt can come both externally and internally, but persistence is what sustains progress. Air Aware Labs itself reflects this mindset. Just a few months ago, the company was still in an intensive building phase; today, it is accelerating rapidly. AirTrack’s evolution mirrors a broader shift from awareness to action.
For students like me, conversations like this do more than explain technology; they illuminate pathways, demonstrate long-term commitment, and make the future feel tangible. And six months from now, I suspect this story will have evolved even further.
