Retirement Plans for Founders & Solopreneurs

The retirement plan your
business income deserves.

You built something. But without the right plan structure, you're leaving hundreds of thousands in pre-tax deferrals on the table — and possibly paying more in taxes than you should. We help to optimize that.

The Problem

Most high-income founders are
dramatically underprepared for retirement.

Not because they aren't earning. Because no one structured their plan to match what they actually make — or what's possible.

"You've spent years building a business that generates real income. But your retirement strategy was probably designed for someone with a W-2 and a company match. That's the gap we close."

$0
Startup tax credits claimed
Most new plans qualify for up to $16,500 in IRS tax credits. Most founders never knew to ask.
~$7K
Average SEP-IRA annual deferral
Far below what a properly structured 401(k) + Cash Balance plan allows for the same income level.
35%+
Marginal rate paying taxes now
Every dollar you could have deferred — but didn't — was taxed at your highest rate. That's permanent loss.

How We Support You

Not just a plan. A retirement infrastructure
built around your financial life.

Investably designs, implements, and manages ERISA-governed retirement plans end-to-end — so you capture every dollar available to you, stay fully compliant, and never have to think about the mechanics again.

Step 01
Plan Design & Structure

We start with your income, entity type, age, and goals — then design the optimal plan structure. Solo 401(k), safe harbor 401(k), or a combined 401(k) + Cash Balance plan that can unlock $100K–$300K+ in annual pre-tax deferrals for high earners.

Step 02
Tax Credit Capture

We identify every applicable SECURE 2.0 credit at plan inception — startup cost credits, employer contribution credits, and auto-enrollment credits — and make sure you don't leave a dollar behind in your first three years.

Step 03
ERISA 3(21) Co-Fiduciary

We serve as your ERISA 3(21) investment co-fiduciary — sharing fiduciary responsibility for investment decisions alongside you as plan sponsor. We select and monitor the investment lineup, provide documented recommendations, and bear shared liability so you're never carrying that weight alone. Where applicable, we also coordinate a 3(38) discretionary investment manager — fully transferring investment decision-making authority and liability away from you as plan sponsor.

Step 04
Actuarial & Compliance

We coordinate with third-party administrators for your annual actuarial valuations for Cash Balance plans, IRS funding calculations, Form 5500 preparation, nondiscrimination testing, and DOL reporting — all handled. You focus on your business; we keep the plan clean.

Step 05
Financial Wellness & Coaching

Ongoing enrollment support, annual retirement readiness reviews, deferral optimization coaching, and year-end tax coordination with your CPA — so the plan actually gets used to its full potential year after year.

The Difference

The fragmented approach vs.
The Investably approach.

Founders may sometimes end up with a plan that was easy to set up — not one that was designed to maximize their outcome. Here's what that gap looks like in practice.

The Typical Approach
  • SEP-IRA or basic 401(k) set up for convenience, not optimization
  • No actuarial analysis — Cash Balance potential ignored entirely
  • Startup tax credits never identified or captured
  • Plan sponsor liability not addressed or explained
  • No fiduciary named — founder exposed to compliance risk
  • Form 5500 and testing left to the founder to figure out
  • No integration with personal tax strategy or CPA
  • No ongoing education — employees don't engage, founder doesn't maximize
The Investably Way
  • Plan structure engineered to your income, age, and goals
  • Cash Balance analysis for every eligible high-income founder
  • All applicable SECURE 2.0 credits identified and claimed
  • 3(21) co-fiduciary coverage — shared liability, your risk reduced
  • ERISA-compliant investment oversight from day one
  • Form 5500, actuarial valuations, and testing — all handled
  • Year-end coordination with your CPA on contribution strategy
  • Ongoing financial wellness that drives real deferral behavior

The Integrated Approach

The integrated approach for closely-held business founders.

Investably connects your retirement plan to your broader financial picture — tax strategy, cash flow, and long-term wealth goals — so every piece reinforces the others.

Retirement plan + tax strategy
Contribution decisions are coordinated with your CPA and tax profile — maximizing deductions in high-income years and adjusting when income dips.
Retirement plan + cash flow planning
We model your contribution capacity against your business cash flow so you're never over-committed — and never under-contributing when the income is there.
Retirement plan + business transitions
Scaling, hiring, selling — your plan structure evolves with your business. We adjust plan design, eligibility rules, and contribution strategy as your situation changes.

Why Work With Us

Built for the founders building lasting wealth.

Solopreneurs and small business founders are often underserved when it comes to retirement plan design — not because the tools don't exist, but because no one has brought institutional-quality expertise to where they actually are. That's exactly what Investably does.

"Founders building something real deserve the same level of rigor in their retirement plan as any large institution — from day one, not just when they've crossed some arbitrary threshold."

Solopreneur & founder specialty
We work exclusively with the kinds of clients most plan advisors overlook — self-employed professionals, single-owner businesses, and small teams in startup and growth phases where the plan design decisions matter most.
Startup to growth phase expertise
From first-year plan setup through hiring, scaling, and eventual business transition — we design plans that evolve with you, not plans built for where you were ten years ago.
Industry-leading plan providers
We work with best-in-class recordkeepers, third-party administrators, and actuarial firms — the same institutional-grade providers used by large plans — so your plan benefits from top-tier infrastructure regardless of its size.
