AI-native carrier infrastructure for the embedded insurance market. Series Seed -- $20M target raise.
Carriers optimized for rare, catastrophic risk -- the burning house, the totaled car, the $100M program. Their entire cost structure assumes low-frequency, high-premium events.
The growth market is now high-frequency, low-volume, embedded in every checkout and SaaS platform. The economics that protected incumbents now lock them out.
"Insurance is bigger than payments and the economics per transacted dollar are juicier, except it is too complicated to do." -- Justin, Rally Ventures
Total Addressable Market
Global embedded insurance premiums, projected 2028. Growing at 35%+ CAGR from $72B in 2025.
Venture-backed, tech-first MGAs from a universe of 10,000+ showing tech-forward characteristics
Serviceable Addressable
U.S. embedded insurance programs suitable for an AI-native carrier. Sub-$50M GWP per program.
Year 1 Aggregate GWP
Conservative. When infrastructure becomes accessible, market expands 10-100x.
The Inverted Market thesis. Stripe/Shopify analog. Creating TAM, not capturing it.
The Translator-Operator. We teach you the category and run the play. You keep building.
The Trust Architecture. Every data object has a birth certificate. Auditable by default.
Primary -- Year 1
Funded SaaS founders who discovered embedded insurance as a revenue line. Zero insurance knowledge. Need a teacher and operator.
High credibility
Serial MGA founder on program 2 or 3. Catastrophically let down by a carrier partner. Demands architectural proof, not promises.
Highest revenue
High-performing MGA running $50M+ GWP. Joined every "exclusive" ecosystem and found them all empty. Wants asymmetric advantage.

Usage drives natural tier progression. The product surfaces upgrade triggers.
GWP growth, team additions, and feature adoption drive tier upgrades
PLG Readiness: 3.2/5.0 -- Moderate fit. PLG accelerates qualification, it does not replace the enterprise sales process.
Not a webinar funnel. Not a challenge launch. An application-based, capacity-constrained partnership model with genuine scarcity.
Statutory surplus limits aggregate GWP. Onboarding bandwidth maxes at 10. Ethan's personal involvement is finite.
Locked economics, governance seat, permanent naming in the Slingshot story.
Slingshot evaluates for Collective fit, not just revenue. Real curation, not theater.

Progressive risk retention expands net margins from 5% carrier fee to 8-12% on retained risk. At maturity, 15-20% on well-performing books.
Legacy carriers charge 5% for paper only. Slingshot delivers $375-575K in services at $5M GWP -- 1.4-2.1x price-to-value ratio.
Startups pay Stripe 2.9%+$0.30 when banks offer 2.1% because the experience justifies the premium. Same dynamic.

Rally is not a passive LP. Justin and Jeff are co-founders with 20+ years in embedded finance. Their portfolio IS the pipeline.
15-20 portfolio companies with embedded insurance potential. Justin sends personal emails. 60-80% expected response rate.
3-5 expected Founding Cohort applicationsRally portfolio company providing AI development expertise. "Super proven" -- accelerates platform build timeline.
Rally leading $7-10M validates the thesis for co-investors. Target 1-2 additional: one strategic reinsurer, one fintech VC.
15-20 companies. Justin personal emails. Weeks 1-4.
15-20 founders. Peer operator credibility. Weeks 2-4.
10-15 contacts. Lloyd's, Tokyo Marine. Dual-purpose: capacity + MGA signal.
ITC, AAMGA, CAS, SaaStr. 15-25 pre-booked meetings per event.
Every data object carries a birth certificate. No competitor offers provenance or chain of custody.
The bordereau number is provably real. Not the version after quiet carrier-side adjustments.
Brock is both co-founder and first customer. The MGA voice is permanently at the founding table.
Built for $25-policy checkout economics. Legacy carrier OpEx makes this structurally uneconomic.
Profitably serve $1-20M programs. State National averages $133M per program. Structurally locked out.
AI, data, and carrier ops built in-house as one system. Not 16+ vendor point solutions assembled post-hoc.
These require ground-up architecture or unreplicable founding circumstances. Budget alone cannot replicate them. Swiss Re tried with iptiQ at $750M revenue and is selling it off.
No other carrier has a founder who is simultaneously a Fellow-level actuary, a former Chief Actuary/CDO at a $10B carrier, and a person who writes production code.
This credibility IS the marketing. It bridges the historically fatal gap between insurance domain expertise and technical architecture.
Ethan comments substantively on 15-20 high-value LinkedIn accounts daily: Insurance Journal editors, MGA founders, insurtech CEOs, SaaStr leaders, reinsurance executives.

Existential threat if Stripe enters embedded insurance at the carrier layer.

Legacy carriers spent 200 years building for the past. Slingshot is the infrastructure for the market that is actually growing.
