Known so far (unverified)
Section titled “Known so far (unverified)”Tier-labeled to be honest about how thin the current basis is — none of this has been run through the evidence map yet.
| Signal | Tier | Note |
|---|---|---|
| Supply-chain planning/management AI for restaurant chains (demand forecasting, inventory, COGS) | INFERRED | From product positioning; verify against the live site. |
| Enterprise customers include Din Tai Fung and Bonchon | INFERRED | Named in scouting signals; confirm first-party. |
| Backed by F4 Fund (listed under Logistics & Supply Chain) | INFERRED | Confirm on the F4 portfolio page. |
| NYC-based; small founding team (~3) | INFERRED | Williamsburg/Brooklyn office and team size unconfirmed. |
| ~$2M seed, closed ~February 2026; Series A “imminent” | SPECULATIVE | Sourced from a recruiter posting that does not name the company — attribution itself is an inference. Not confirmed via Crunchbase/PitchBook/press. |
| Stack: TypeScript, Next.js, React, Node.js, Express, PostgreSQL, Redis, AWS, Python | SPECULATIVE | Same recruiter posting; treat as a TS-first signal to verify against their own ATS/JDs, not as fact. |
To verify next pass
Section titled “To verify next pass”- Funding amount, round, and date — primary source (Crunchbase / press / F4).
- Company identity vs. the recruiter JD — confirm the posting is actually SightlineOS before citing its stack.
- Office location (Williamsburg, Brooklyn?), team size, founders.
- First-party engineering signal: own ATS (Greenhouse/Ashby/Lever), eng blog, observable product behavior.
