Angel investing, sector by sector
What angels should evaluate changes by sector — a fintech deal and an agtech deal require genuinely different diligence. Here is what to know before investing in each of the region’s major startup categories.
11 sectors
Fintech
The largest category by deal flow — regulatory status, unit economics, and rail partnerships.
AI
Wrapper versus moat, compute burn, and data rights as foundation models commoditize.
Healthtech
Regulatory approval pathways, payer logic, and physician adoption.
Deep tech
IP ownership, how much technical risk is retired, and capital fit for the stage.
Agtech
Distribution to a fragmented farmer base, seasonality, and capital intensity.
Edtech
Real engagement rates, who actually pays, and accreditation status.
E-commerce
Logistics-adjusted unit economics and competing in MercadoLibre’s shadow.
SaaS
Selling regionally versus selling to the US at a LATAM cost base, across 10 sub-verticals.
Climate tech
Capital intensity, subsidy dependency, and utility-scale sales cycles.
Infrastructure
Capital intensity and customer concentration in the "picks and shovels" layer.
Hardware
Bill of materials, production readiness, and supply-chain exposure.
Cross-cutting: business & revenue models
Before you dig into any single sector, it helps to separate how a company is structured (marketplace, platform, D2C) from how it actually makes money (subscription, freemium, take-rate, ads) — the two are independent choices, and mixing them up leads to comparing apples to oranges across deals.

How sector changes the diligence, and what stays the same
Sector decides which risk dominates
The same seed-stage cheque carries a different dominant risk depending on where it goes. In fintech the binding constraint is usually licensing and the regulator's timetable. In agtech it is seasonality: a company may only get one real commercial test a year. In hardware and deep tech it is capital intensity — the gap between a working prototype and a manufacturable product consumes more money than the round in front of you. Knowing which risk dominates tells you what to spend diligence time on.
What does not change across sectors
Four questions apply everywhere: can this team ship, is anyone paying, what does it cost to acquire the next customer, and how long does the current cash last. A sector guide should sharpen those questions, not replace them. If a founder cannot answer the four in a sector you find exciting, the excitement is yours, not the business's.
The regional dimension
Sector risk in Latin America is often a market-structure question rather than a technology one. E-commerce competes with an incumbent marketplace of unusual regional dominance; SaaS has to decide early whether it prices for local budgets or global ones; climate and infrastructure ventures depend on public procurement and regulated tariffs. These are not reasons to avoid a sector — they are the specific things to ask about before writing the cheque.
