Top Software Startups in North America

We are a boutique performance growth agency focused on scaling the world's biggest apps

Therapists hold the world together. They also run businesses, file insurance claims, write letters, fill forms, supervise new grads and do hours of paperwork every night. Practice management software has existed for decades. It records what therapists do. It can't actually do any of it. Klara is the AI at the heart of Klarify. She handles the work that comes after the session: clinical notes, treatment plans, clinical letters, insurance claims, between-session resources, supervision prep and finding new clients. More than 11,000 therapists use Klarify today. Privacy comes first: Klara never trains on therapists' notes or client data. Our mission is to empower therapists, not replace them, so they can focus on the one thing only a human can do: be present with their client. Klarify is backed by Y Combinator (Spring 2026) and has raised $1.7M. Moody (CEO) is a second-time founder who co-founded Circleback.ai and hosts the Future of Therapy Podcast. Bergie (CTO) built LLM infrastructure at Workday.

Construction is one of the largest industries in the world, but it is also one of the least technologically innovative spaces. Conducting fast and accurate cost estimates is a massive pain point because of the tedious nature of takeoffs (measuring & counting materials needed from the drawings). Bobyard automates the construction takeoff process with CV and NLP models to make cost estimates 10x faster while eliminating mistakes. We are a lean startup backed by some of the best VCs in the world: 8VC, Primary, and Pear. Almost all of the work lies ahead of us. We are excited to create next-gen software for the built world!

VenturSeed invests and partners with founders at the pre-pre-seed stage, and helps them become part of our ETF stock-like portfolio. We help underrepresented entrepreneurs create strong, independent companies

Spero helps practices offer virtual IOP (VIOP) to patients anywhere who are transitioning out of IP care, or who need more than OP care to prevent IP hospitalization. This increases access to care while lowering readmission rates. We focus on simplifying consultations and documentation for clinicians so they can focus on patient care, while also tracking patient progress through assessments and behavior reports to create a predictive care model. This helps inform clinicians when a patient is high risk, progress is regressing, individualizes treatment plans, and offers other insights. This data quantifies patient symptoms better than normal qualitative documentation. Spero helps clinics improve patient care and quantify treatment outcomes to allow clinics to negotiate VBC contracts with insurance, which increase clinic revenue and lowers costs for insurance. VBC means higher quality care, in-network coverage for patients (lower out of pocket costs), and decreased readmission rates.

Enurgen builds DUET, a 3D physics-based software platform for utility-scale solar and battery storage. DUET simulates what a plant should produce at every timestep of a 30-year life, compares it against what the field actually did, and attributes the gap down to the individual component. Conventional monitoring can tell you a plant is underperforming — working out why is the hard part, and that's the problem we solve. Every megawatt-hour a solar plant fails to produce is one that comes from somewhere else. Recovering it needs no new land, no new panels, and no new interconnection queue — just a correct answer about what went wrong and where. The model came out of SUNLAB at the University of Ottawa, with more than a decade of research behind it. It runs across the asset lifecycle: - Design — terrain-aware 3D modelling to establish a realistic performance baseline before anything is built. - Construction — analysis from the moment equipment comes online, so issues surface before commercial operation rather than years into it. - Operations — minutely, string-level analysis with automated root-cause loss detection, separating recoverable losses from the ones that aren't and routing the fixable ones into the maintenance system. We're a small, early-stage team with an office in Ottawa, Ontario. The engineering work is heavy on data: analytical queries over fleet-scale time-series, streaming pipelines feeding live analytics, on-prem software that keeps running when the WAN doesn't, and dashboards that stay fast at that scale. Research sits at the same table as engineering, so the physics and the software get built against each other. Hybrid-first, with remote on the table for any role. Every role includes an equity grant. You don't need a solar background — the domain is interesting, our customers are sophisticated, and you'll pick it up.

We’re building Reflow, a workforce and workflow intelligence platform that helps teams understand and improve how work gets done.
