IRA Financial
IRA Financial built its name helping retirement savers buy the things ordinary brokerage menus leave out. Now it is stitching real estate, crypto, private companies and public markets into one account - while asking customers to take on the judgment that freedom requires.
Advanta IRA
Advanta IRA gives retirement savers a way to put houses, private loans, gold and startup stakes inside tax-advantaged accounts. The freedom is real - and so is the paperwork.
Penelope
Penelope is a New York fintech that makes 401(k) retirement plans practical for the businesses that usually get ignored - the corner shop, the two-person startup, the solopreneur. Founded in 2021 by former Wall Street executive Jean Kim Smart and named after her daughter, the company started as a low-cost, self-service platform offering Pooled Employer Plans, traditional 401(k)s and Solo 401(k)s, and has since built a cloud-native, API-first, SECURE 2.0-ready recordkeeping platform that independent recordkeepers and benefit providers can run under their own brand. The pitch is unglamorous but real: automate the paperwork, cut the cost, and let roughly 60 million Americans who work for small employers start saving.
Ankur Nagpal
Ankur Nagpal is an Indian-American entrepreneur, investor, and capital-efficient founder who built Teachable from a dorm-room frustration into a $250M exit, then reinvented himself as a solo-GP venture investor (Vibe Capital, $70M+ raised), fintech builder (Carry, acquired by AngelList in 2026), and prolific financial educator (Silly Money newsletter, 86K+ subscribers). In April 2026 he joined AngelList full-time as GP of USVC, a public venture fund co-chaired by Naval Ravikant with stakes in xAI, Anthropic, OpenAI, and Vercel.
