A small team building a serious operating system.

Manifesto · 001

Two founders, four open seats, one product. We ship the governance before the speed, the specialists before the generalists, and the audit trail before the demo.

Hiring carefully — for the long haul.

Section 01 · The founders

Two operators. One product.

Marvin leads the technical team and ships the product. Karol leads distribution and carrier success — turning pilots into renewals across LATAM.

Leads the technical team. Owns the product end-to-end.

Marvin Amador

I want every adjuster who opens a Grivara claim to feel like the system has already done the homework — agents, evidence, governance, and a clear next action — without ever wondering what the model is hiding.

Marvin leads the technical team and owns the product end-to-end. He architected Grivara's specialist agent fleet, governance harness, and fraud graph from first principles, and he still writes the code that ships into pilot carriers on Monday morning.

He sets the engineering bar, runs the technical hires, and pairs daily with the team on the systems that decide reserves, denials, and SIU referrals. Where most AI startups treat governance as a deck slide, he treats it as production infrastructure — every output explainable, every override audited, every model swap reviewable before it lands in a carrier's tenant.

Owns distribution. Owns whether the carrier renews.

Karol García Figueroa

A pilot is not a sale, and a sale is not a successful deployment. My job is to take a carrier from the first conversation to the moment their adjusters cannot imagine working without us — and to keep them there.

Karol owns distribution and carrier success across LATAM. She runs the motion that turns a first conversation into a signed pilot, a signed pilot into production usage, and production usage into a renewal — with carrier operations teams that pick up the phone when she calls.

She is the founder our carriers see most: walking adjusters through their first decision packet, pressure-testing rollout plans with COOs, and feeding the field back into the roadmap so that what Marvin's team ships next is what an actual claims floor will use on Monday.

Section 02 · Operating principles

What we agree on before we hire anyone.

Four rules that explain the product and the team in one read. We test fits against these, not against keywords on a CV.

I

Govern first, ship second.

Every consequential decision sits behind a policy gate. We design the rails before we design the speed.

Principle / I
II

Specialists over generalists.

Ten focused agents with structured output beat one big model with vibes. The same goes for the team.

Principle / II
III

Carrier reality, not deck reality.

We pilot in the operations the rest of the industry pretends don't exist. The product earns its claims in the field.

Principle / III
IV

Audit trails, all the way down.

Decisions, overrides, gate verdicts, model versions — every step lands in the record. Including ours.

Principle / IV

Section 03 · Open seats

Four roles. Founding cohort.

Most of our hires will work directly with a founder for their first six months. If you want to ship into production from week one, this is the moment.

Manifest · 2026.04 · 4 roles · 2 open · 2 soon
