Breaking new ground in online eyecare.
Quadrant Eye is on a mission to improve eyecare access and fight preventable blindness. We're building the next generation eye exam... inside the average American home. Our team wants to enable patients' best and most visually rich lives. To this end, we're looking for curious and nimble minds to help us develop the world's first fully online eye exam and ultimately deliver high-quality eyecare at scale. Some QE highlights: 🐝 We're a team of surgeons, scientists, venture partners, and hackers who mean business. 💸 Our backers include Y Combinator, Khosla Ventures, and the creator of Google Image Search. 🍥 We're a mission-driven company tackling an eye health market worth $USD137B. 🌟 Our core focus is currently the development of patentable deep tech, and our overall vision is to change eyecare for good.
As reported in public records reported — not modeled.
Solid bars are reported offering amounts reported; hatched bars are the modeled post-money valuation est. — both on one shared scale so you can read raise-vs-worth at each round directly. Use the toggles to overlay data labels and the niche-peer / market average value lines.
No round amounts on record to chart.
No staged rounds to sequence.
Round size and date are reported; the stage label is inferred from round size. Valuation is modeled from stage benchmarks. Directional, not a quoted figure.
Not enough modeled valuation points to chart a trajectory.
Benchmarked against 8525 companies in this sector. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.
Raised more than 96% of sector peers (real $). Modeled value above 96% of peers (estimate).
Stage is inferred from round size est., not reported on the filing — a round's dollar size maps to a bucket: Pre-Seed <$1.0M · Seed $1.0M–$4.0M · Series A $4.0M–$15M · Series B $15M–$40M · Series C $40M–$100M · Series D+ $100M–$400M · Growth/Late >$400M.
