Tidewise

Asset-level flood risk for coastal utilities.

Series A · 2026 · 10 minutes

The problem

Utilities plan floods with maps older than the storms

4,200coastal utilities in the addressable market

20 yrmedian age of the flood model used for capex planning

$2.8Bannual spend exposed to avoidable flood damage

1 in 3outages traced to an asset the utility already knew was exposed

The insight

The risk is already in the data. It is not in one place.

Satellite subsidence, tide gauges, asset registers, and outage history describe the same asset. Tidewise joins them into one risk score.

The product

Three workflows, one risk model

Monitor

Live risk map by asset, feeder, and substation.

Prioritize

Rank capex by avoided outage cost and criticality.

Plan

Scenario the next storm, budget cycle, and hardening plan.

API-first; sits beside GIS and EAM, not instead of them.

Market

Bottom-up: 4,200 utilities, $670k average contract

Segment	Utilities	ACV	Why now
Coastal municipal	2,900	$310k	Rate-case pressure, FEMA mapping
Investor-owned	900	$1.2M	Capex hearings, resilience mandates
Co-ops / ports	400	$220k	Insurance and grant requirements

$2.8B serviceable market · no single incumbent owns the risk layer.

Traction

14 utilities, $1.2M ARR, 132% net revenue retention

$1.2MARR, up from $310k

132%NRR after 12 months

9 moCAC payback

14production utilities

Business model

Per-asset subscription, expanded by API

Land

$180k–$420k annual subscription by asset count; implementation in 6 weeks.

Expand

API calls, scenario modules, and storm-response seats. 78% gross margin at scale.

Competition

Consultants sell reports. Tidewise is the system of record.

Alternative	What it does	Why it loses
Engineering consultancies	One-off flood studies	Static, expensive, not operational
GIS point tools	Maps and layers	No asset criticality or capex workflow
Insurance models	Portfolio loss estimates	Not asset-level, not utility-specific
