SeedTee is a compressed tee made of sand, turf seed, and nutrient. It holds the ball for the strike — then the next rain or irrigation cycle breaks it down into the tee box, overseeding the exact turf golf damages most.
Every round starts with a divot and ends with litter. Courses pay twice: once to clean it up, and again to regrow what golf tore out.
Wood and plastic fragments accumulate on every tee box. Crews hand-pick them daily, and what they miss dulls or chips reel-mower blades — a maintenance cost no one budgets for but every superintendent knows.
Tee boxes — especially on par 3s — are the most concentrated wear zones in golf. Courses re-seed, top-dress, and rotate markers all season just to keep them playable. It's continuous, labor-heavy spend.
Durable plastic tees were sold as the sustainable upgrade to wood. They fly on mis-hits, disappear into rough and bunkers, and persist for decades. Sustainability-mandated clubs are actively looking for an exit.
One product, three lives: equipment during the swing, disappearing act after, turf input by morning.
Kiln-dried sand and a regionally matched turf-seed blend are compression-molded with a plant-based binder into a standard tee profile. Rigid when dry, stable in the bag.
TARGET SPEC: holds driver-speed impact ≥1 strikeStandard heights and cup geometry — nothing about the swing changes. On impact it snaps clean or stays planted. Either way, the golfer walks off and never thinks about it again.
FORM FACTORS: 2¾″ · 3¼″ · par-3 shortThe next irrigation cycle or rainfall dissolves the binder. The sand top-dresses the divot, the seed germinates in it, and the nutrient charge feeds establishment. The tee becomes the repair.
TARGET SPEC: full breakdown within 24–48h of soakingThat single inversion changes who's willing to pay — from golfers alone to the courses themselves.
| Wood / bamboo tees | Plastic tees | SeedTee | |
|---|---|---|---|
| After the shot | Splinters left as litter | Lost into rough; persists for decades | Dissolves into the tee box |
| Effect on turf | None — cleanup burden | None — pollution burden | Overseeds + top-dresses the divot |
| Who pays | Golfer | Golfer | Golfer, pro shop, and the course itself |
| Course's attitude | Tolerated | Increasingly banned | Actively wants it used — and branded |
Tees are bought again and again, all season, by golfers who never comparison-shop. The wedge in is small; the surface it opens is not.
| Segment | Entry price | Why they buy |
|---|---|---|
| DTC golfers | $12 / 30-pack | Feels good, plays the same, great gift — the "leave the course better" story sells itself on social. |
| Pro shops & retail | Wholesale, ~50% margin | High-margin impulse item at the register; sustainability story matches where club branding is going. |
| Courses & resorts | Bulk + logo-branded | The only tee that reduces their maintenance load. Range and par-3 programs turn a litter problem into an overseed program. |
| Corporate & events | Custom runs | Tournaments and brands want a sustainability line in the gift bag that's real, not greenwash. |
Finalize binder + compression spec; strike-durability and breakdown testing across climate conditions.
Pilot with [3–5 partner courses] — driving ranges and par-3 tee boxes, germination tracked against control plots.
First production run, direct-to-consumer launch timed to season opening; pro-shop pilot in trial-course shops.
Branded bulk offering and range subscription, sold on trial data. Begin regional seed-blend expansion.
Capital goes to the three things that de-risk everything else: locking the formulation, running named-course field trials, and the first production run.
