The most important diagnostic tool in a wastewater treatment plant is a microscope, a clipboard, and an operator who has been staring into sludge for twenty years. The problem, as a growing number of utilities are discovering, is that the operator is about to retire. Into that gap steps Nyad, a Birmingham-based startup that is betting its AI can read the microscope first.
Founded in 2024, Nyad sells a software copilot named Nymph that uses digital microscopy and machine learning to classify the teeming world of bacteria, algae, and protozoa in activated sludge. The goal is to give plant operators real-time biological diagnostics and corrective recommendations, replacing a slow, manual process that depends on scarce expertise [Hypepotamus, March 2026]. For an industry facing a wave of retirements and tightening environmental permits, the pitch is less about futuristic AI and more about preserving baseline operational intelligence.
The wedge is the clipboard
Nyad’s entry point is elegantly simple: the existing workflow. Operators already take regular microscope samples to check the health of the biological process that breaks down waste. They manually identify organisms, note floc structure, and cross-reference findings with chemical data and permit requirements,all on paper. Nymph aims to digitize that entire chain. An operator uploads an image from a digital microscope; the software’s computer vision models identify and quantify organisms like ciliates, rotifers, and filamentous bacteria, then suggests actions [SiliconANGLE, March 2026].
The company is careful to frame its tool as a copilot, not an autopilot. Its stated mission is to “give wastewater operators world-class plant intelligence while keeping human judgment in command” [nyad.ai/mission, 2026]. This is a sensible approach for a conservative, compliance-driven industry. The software also integrates other data sources, like SCADA system outputs and permit documents, to provide context-aware guidance [nyad.ai, 2026]. The value proposition isn’t just speed, but consistency and knowledge retention as experienced staff depart.
Founders from an unlikely source
The co-founders, Virginia Szepietowski and Christopher Braithwaite, are British entrepreneurs who relocated to Alabama to build the company. Their origin story is not from the world of civil engineering, but from open-water swimming. They began investigating wastewater treatment after repeatedly falling ill during triathlon training in the UK [Techstars, August 2026]. Szepietowski, the CEO, spent six months researching the water sector before launching Nyad. The team, which stood at seven people by August 2026, came together through the Techstars 2025 accelerator program [Techstars, August 2026].

Funding and early traction
Nyad has raised a total of $2.2 million in equity funding, according to a March 2026 report [AlleyWatch, March 2026]. Its most recent round was a $1.3 million pre-seed led by Boost VC, with participation from Draper Associates, Halogen Ventures, and others [Hypepotamus, March 2026]. This followed earlier non-dilutive wins, including a $25,000 prize from Alabama Launchpad in late 2024 [Alabama Launchpad, December 2024].
The capital is fueling commercial expansion. The company reported operating in six states by August 2026, though specific customer names or counts are not publicly detailed [Techstars, August 2026]. The hiring of a Head of Content in March 2026 suggests a focus on building industry credibility and lead generation [LinkedIn Jobs, March 2026].

The incumbent is institutional memory
Nyad’s most credible risk is not a direct software competitor,none are named in available sources,but the entrenched, low-tech status quo. The real incumbent is the combination of institutional knowledge, manual processes, and deep skepticism of new technology within municipal utilities. Convincing a plant manager to trust an AI’s read of a microscope slide over a veteran operator’s gut feeling is a profound behavioral and sales challenge. The regulatory environment adds another layer; any recommended action must be defensible in an audit.
The company’s plausible answer is its wedge-and-copilot approach. It is not asking operators to cede control, but to augment their process with a digital assistant that never retires. Early adoption in six states indicates some utilities are willing to experiment [Techstars, August 2026]. The bet is that the pressing need to capture retiring expertise will outweigh institutional inertia.
The unit economics of a prevented violation
The financial case for Nyad hinges on avoiding cost, not just creating efficiency. A wastewater plant’s expenses are dominated by energy (for aeration) and chemicals (for nutrient removal). A biological upset,like a proliferation of filamentous bacteria causing sludge bulking,can spike those costs and risk a permit violation. The back-of-the-envelope math is straightforward. If Nymph helps a medium-sized plant avoid just one significant non-compliance event per year, the savings in potential fines (which can reach tens of thousands of dollars) and avoided chemical overuse could easily cover a five-figure software subscription. The real payoff is preventing the event that never shows up on the ledger.
For Nyad to become essential, it must prove it can reliably beat the diagnostic accuracy and cost-saving intuition of a seasoned human operator. That is the high bar it has set for itself. Its success won’t be measured in flashy AI benchmarks, but in the quiet, consistent avoidance of problems in 7,000 treatment plants across the country that nobody ever wants to think about.
