About
ConvexBeta provides discretionary and non‑discretionary portfolio management for individual investors, trusts, IRAs, and small businesses, delivering equity, fixed‑income, and blended strategies. The firm emphasizes tax‑efficient investment counsel and coordinates with clients’ tax, accounting, and estate‑planning advisors when developing plans.
The firm uses an active, tax‑aware investment process that combines top‑down strategic allocation with bottom‑up security selection, quantitative screening, tax‑loss harvesting, option collars, and the use of low‑cost ETFs and individual securities to manage costs and tax consequences. Portfolios are customized through an Investment Policy Statement created via an interview approach and are monitored and rebalanced using industry software; clients may also opt into a stock‑lending yield enhancement program through the firm’s custodian.
Noteworthy for a boutique advisor, ConvexBeta is a very small, concentrated practice (two advisors, roughly ten client relationships and modest AUM) that nonetheless draws on senior management experience at institutional and public‑sector levels, including oversight of municipal and public‑agency portfolios and roles at bank‑affiliated asset managers. That institutional background, combined with the firm’s willingness to work with trusts, small businesses, and to coordinate with other professional advisers, distinguishes its client service mix from many peers of similar size.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
