Seed to Series B · New York

Capital for the
AI-native era.

Gothic Holdings backs companies that were built around models from the first commit — not retrofitted with them. We underwrite decades rather than demos, and we run a research lab of our own, so the people judging your architecture have shipped one.

What we look for

Three tests, applied in order.

Most firms describe what they invest in. We would rather tell you what we check, because that is what you will actually experience if we meet.

AI-native from the first commit

The model is not a feature bolted onto a product; it is the reason the product can exist. We look for teams whose architecture, data pipeline and pricing all assume inference is a primary cost line. Retrofits rarely survive the second model generation.

Architecture review at first meeting

Markets where models change the cost structure

Software that is ten percent better rarely dislodges an incumbent. Software that removes most of a cost line does. We underwrite the unit economics of the market you are entering — not the demo you are showing — and we model what happens when inference gets an order of magnitude cheaper.

Model-economics underwriting

Founders with research taste

Taste is the ability to tell which results will hold. We look for founders who read the literature, run their own evaluations, and can say precisely why the obvious approach fails. Credentials are optional. Judgment is not.

Technical review by lab researchers

Portfolio snapshot

Four sectors. Twenty-three companies.

We hold positions in a small number of places we understand well. Companies are described by what they do rather than what they are called — most of the portfolio is not public about its investors, and we prefer it that way.

Applied models

8 companies

  • Clinical documentation for specialty practices
  • Underwriting review at a mid-market carrier
  • Design-review automation for structural firms

Infrastructure

6 companies

  • Inference scheduling across mixed GPU fleets
  • Deterministic replay for agent systems
  • Private model gateways for regulated buyers

Vertical agents

5 companies

  • Freight exception handling at brokerage scale
  • Permitting workflows for civil engineering
  • Remittance matching for equipment lessors

Data & evaluation

4 companies

  • Domain benchmark construction for legal work
  • Synthetic data for low-resource defect classes
  • Continuous evaluation for production fleets

The Lab

We train our own models.

Gothic runs a small research group in-house — four researchers working on efficient inference, domain-specific small models, and evaluation tooling. It exists for one reason: an investor who has trained a model can tell the difference between a hard problem and an expensive one.

Findings move in both directions. Lab work sharpens our diligence; portfolio companies get the benchmarks, the ablations and the engineers who ran them. Where a result has value beyond the portfolio, we license it selectively rather than let it sit in a drawer.

Introductions

Building something AI-native? We read every note.

No warm introduction required. We reviewed 2,340 companies last year and met 190 of them; roughly half arrived cold. Tell us what you are building, what the model does that ordinary software could not, and what the capital is for.

If it is a fit, you will hear from a partner and a lab researcher within one business day. If it is not, you will get a real answer and the reason behind it. Our standard is a decision inside fourteen days of the first meeting.

Introduce your company

Five fields. Read by a partner, not a filter.

Everything you send is held in confidence and never shared outside the firm.

Received.

Thanks — we'll be in touch within one business day.

What happens next
A partner reads your note and replies either way. If there is a fit, we schedule 45 minutes with an investor and a lab researcher.
Our decision standard
Fourteen days from first meeting to a yes or a no, with reasoning.
