Savvly

Savvly offers the Longevity Benefit, an SEC-registered security (NOT an annuity) that provides longevity protection by investing contributions into a low-cost S&P 500 index ETF and paying structured milestone cash payouts at ages 80, 85, 90, and 95. When participants withdraw before a milestone, their allocation transfers to remaining investors — a longevity-pool / mortality-credit mechanism that can lift returns above pure market performance. Accounts are portable across jobs and require no health screening. Savvly publishes an open, rate-limited Public API (OpenAPI 3.1) for product information, eligibility, FAQ, comparisons, and retirement/lump-sum/monthly projections, plus a first-party MCP server, an llms.txt, an ai-plugin manifest, and an RFC 9727 api-catalog for agent-native consumption. Backed by Techstars.

Savvly publishes 3 APIs on the APIs.io network: Comparisons API, Product API, and Projections API. Tagged areas include Company, Fintech, Retirement, Longevity, and Investing.

Savvly’s developer surface includes API reference, documentation, and 17 more developer resources.
