Nightglass
Subscription collision warnings for small satellite operators, from our own global sensor grid.
Nightglass builds and operates a worldwide grid of optical and passive RF sensor sites and sells the output as a per-satellite monthly subscription to small operators: custody tracking, orbit determination, conjunction warnings and maneuver screening in one console.

The idea in full
- What
- Nightglass builds and operates a worldwide grid of optical and passive RF sensor sites and sells the output as a per-satellite monthly subscription to small operators: custody tracking, orbit determination, conjunction warnings and maneuver screening in one console. The buyer is a 5 to 50 person satellite company that cannot afford its own tracking and currently relies on free government screening that is too coarse to act on. Subscribers upload planned maneuvers and their own GPS telemetry, which feeds back into the catalog, so every operator's warnings sharpen as more operators join.
- Why now
- The last three cohorts are stacking objects into orbit faster than anyone is tracking them: Dispatch is putting satellites up for manufacturing in space, Beyond Reach Labs is growing football-field-sized solar arrays in orbit, Exosat is building a sovereign constellation, and GRU Space is planning lunar construction. Cascade Space raising the idea of a commercial alternative to the Deep Space Network shows ground infrastructure is now venture-fundable, and 25 new companies entered this cluster in 2026 alone.
- Wedge: first customer and entry point
- Stand up four sensor sites across three longitudes and sell custody-and-conjunction subscriptions to ten YC-adjacent satellite operators launching their first constellation, priced per spacecraft per month.
- Path to 100x
- Space situational awareness and traffic coordination is a $1-10B subscription market today and grows with every object launched, and it is a network business because the value of a catalog is the fraction of operators who share their maneuver plans into it. The first grid to reach majority participation becomes the clearinghouse everyone must join to be screened against, which creates the coordination category and the underwriting dataset behind orbital insurance.
- Ceiling
- Sensor site capital and operations scale with coverage while small-operator subscription budgets stay thin, keeping gross margin and revenue per customer below what a $1B outcome needs.
- Closest real companies, as the generator saw them
- Cascade Space builds ground stations for commanding deep space missions, which is a communications service; Nightglass never talks to the spacecraft and sells observation and warning instead. Constellation Space sells operating software to large network operators and would consume Nightglass data rather than produce it.
- Main risk
- Government space traffic coordination improves enough that free public conjunction data is good enough to fly on.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
3/5
Clearinghouse network effect is real, but sensor site capex scaling against thin 5-to-50-person operator budgets fights the $1B outcome.
Bootstrapper
2/5
Building four sensor sites across three longitudes is heavy capex against ten small operators with thin per-spacecraft budgets.
Operator
3/5
A 5 to 50 person operator has a real conjunction problem, but free government screening is the incumbent and sensor sites are capital-heavy.
Technologist
4/5
Operating a passive optical and RF grid across three longitudes and doing real orbit determination from it is deep work that improves per subscriber telemetry.
Risk
3/5
Owns its own sensor grid rather than renting data, but free government conjunction screening improving is a policy event it cannot hedge.
trends
2/5
Congestion has grown since 2021 and tracking incumbents exist; citing 25 new space companies is demand context, not a 2025-2026 enabling shift.
