SYNTAUR LLC
INVESTMENT BRIEF
2026
Investment Opportunity

The Case for
Manufacturing.

Syntaur holds a near-monopoly on vintage synthesizer parts. The next phase of growth isn't more sales — it's owning the supply chain.

Above 2024 — and trending up
Revenue & profit — 2024 → 2026 est.

The 2025 margin dip was intentional — not a warning sign. Three structural moves happened at once:

Rent started: +$108K/yr
LLC restructuring — tax-advantaged, not a cash drain
Payroll raised: +$65K/yr
Retention investment in a specialist team
Inventory expanded: +$125K
Including tooling for first remanufactured parts — the thesis begins here
02 / The Model Works

We already do this.
It prints money.

Syntaur has proven the in-house manufacturing model with real, live products. These aren't projections — they're 2025 actuals.

Key insight
Roland no longer makes these. Syntaur does. 11 in-house SKUs averaging 75% margin — vs. 45–65% for sourced equivalents.
In-house vs. external margin — current top sellers
03 / The Opportunity Gap

High volume.
Low margin.
Fixable.

These are top-selling items where we're currently leaving significant margin behind. All are sourced externally — meaning someone else pockets the manufacturing margin on every unit.

Power cord, 2-bladeHosa19348%+$3.2K
If only the top 30 externally sourced items were converted to 82% in-house margin, the annual profit uplift at current volume is approximately $105,000/yr — without growing sales at all.

These customers aren't browsing. They opted in to restock alerts. Conversion is near-guaranteed the moment supply exists. This is the definition of zero-CAC demand.
05 / The Strategy

Two vectors.
One flywheel.

Vector A — Margin Repair
Convert low-margin sellers
We already sell these. We buy them from suppliers at thin margins. Manufacturing in-house with 3D printing flips the economics without touching revenue.
▸ Casio hammer caps — 1,346 units/yr at 32%
▸ Korg joystick — 193 units/yr at 57%
▸ Key springs — 117+ units/yr at 49%
▸ Music rests (Yamaha, Alesis) — 457 waiting
Target: +$105K/yr profit on flat revenue
Vector B — Unlock the Waitlist
Create supply for captured demand
3,811 out-of-stock items with signed-up buyers. Many are physical parts — panels, buttons, cases, mechanical parts — that OEM suppliers will never restock. We can.
▸ Roland Juno-106 front panel — 105 waiting
▸ Korg Triton button assemblies — 386 waiting
▸ End caps, Yamaha — 173 waiting
▸ Moog pitch bend/mod wheel — 97 waiting
Target: unlock $200K+ from reman-eligible waitlist items
The Moat
Why no one else will
Syntaur's dominant market position and 3,000+ model catalog means we already know which parts sell. No one else has this data. No one else has the customer relationships.
▸ Wish-list data signals viable SKUs in advance
▸ Near-monopoly = pricing power
▸ In-house technical expertise to reverse-engineer parts
▸ Once tooling is paid off: near-100% margin forever
Compounding advantage: every new SKU we manufacture widens the gap
06 / Financial Projection

Same revenue.
Double the profit.

The pitch isn't "grow faster." It's "keep the same customers, fulfill more of them, and pocket the margin that currently goes to OEM suppliers."

Core insight
Converting $200K of externally sourced COGS to 82% in-house margin generates ~$74K additional profit/year with zero revenue growth. The investment pays for itself in under 18 months.

07 / The Ask

A focused investment
in a proven machine.

1
3D Printing & Tooling Equipment
SLA/resin printers for precision small parts — buttons, springs, keys, panels, housings. Direct path to 80%+ margins on mechanical parts currently sourced externally.
$15,000 – $30,000 one-time capital
2
Dedicated R&D / Manufacturing Role
One person whose sole job is to systematically identify printable/manufacturable items using sales data and wish-list signals, then develop and validate them.
$45,000 – $60,000/yr operational
3
Year 1 Tooling & Materials
First-run materials and tooling costs for 20–30 new manufactured SKUs. After first run, recurring cost drops to materials only.
$20,000 – $40,000 (partially one-time)
Total investment
~$120K
