investing discipline.

The SIP Approach
SIP doesn't just manage portfolios. SIP provides frameworks that turn financial clutter into clarity — and clarity into action.
SIP Method™
A systematic approach to identifying the behavioral patterns that keep capital frozen — the gap between knowing what to do and actually doing it — and building activation pathways tailored to your decision-making style, not generic advice.
SIP Activation Index™
A diagnostic tool that reveals why you're stuck. Are you a Hoarder (safety over opportunity)? An Exit-Seeker (ready to delegate)? An Achiever (earning faster than deploying)? Or an Optimizer (researching indefinitely, never executing)? Know your pattern. Unlock your pathway.
SIP Capital Architecture™
The structural blueprint for organizing capital into three strategic chambers: Income (cash flow and stability), Growth (compounding and appreciation), and Protection (floor reserves and safety) — so you know what's working today, tomorrow, and decades ahead.
Institutional discipline.
Individual mandate.
SIP was founded on one belief: the rigorous frameworks that protect and compound capital at scale should not be reserved for pensions and endowments. They belong to every investor — regardless of account size.
The approach is rooted in two timeless principles: diversification across asset classes and long-term compounding. Not reactive strategies — deliberate choices designed to preserve capital through market cycles and build sustainable wealth over time.
Whether serving institutions managing reserves or individuals navigating life transitions, SIP applies the same standard of care, structure, and accountability to every client relationship. The goal is not simply to manage portfolios — it's to steward capital with intention, aligned with each client's mission, values, and long-term vision.
The SIP Standard
SIP is a Registered Investment Advisor based in Lexington, MA, utilizing Charles Schwab as custodian for client assets.
Working only for you. No commissions, no product sales, no conflicts.
Institutional-grade process. Individual mandate.
Traditional or values-aligned investing. Your capital, your constraints.
Where SIP Focuses
Institutional Advisory Services
Your reserves are growing — but who is actually accountable for the portfolio? Between board meetings and mission delivery, unmanaged reserves drift. SIP holds the line.
Ideal for: Nonprofits, foundations, and endowments under $25M that need institutional-grade discipline without enterprise-tier fees.

You've built wealth through income. Now comes the harder phase — making it compound without you. SIP structures the path forward for individuals with capital sitting idle.
Ideal for: People with capital awaiting deployment — not because they lack ambition, but because they lack a framework they trust.

Meet Anu Rames, Founder & Managing Principal
Before founding SIP, Anu spent nearly two decades as an institutional investor at global firms including BNP Paribas Asset Management, Liberty Mutual Investments, Boston Trust Walden, Essex Investments, and Ardennes Capital. She worked across cycles, crises, and recoveries — and saw where portfolios break. Not in downturns. In structure.
At Liberty Mutual, she served on the 401(k) Investment Committee, stewarding retirement assets for 72,000+ participants. Now she brings that same institutional expertise to individuals and organizations who have never had access to it.
Traditional or values-aligned — backed by clarity, transparency, and decades of proven results. Anu holds an MBA from Babson College and an engineering degree from Calicut University.
Whether you're building a platform, a portfolio, or a second act — Anu can help you launch with clarity and conviction.
