IRA and automated retirement investing

My top recommendation is Betterment, particularly if you want a small-business retirement account that invests automatically without requiring you to select funds, rebalance your portfolio, or manage investments day to day.

The best provider depends on whether your business is just you or has employees. In the U.S., the main options to compare are a Solo 401(k), SEP IRA, and an employer-sponsored 401(k).

Which type of account should you choose?

One important distinction: a broker offering retirement accounts doesn't necessarily manage the investments automatically. Look for a robo-advisor, managed account, or target-date fund option. A target-date fund is often the simplest hands-off choice within a 401(k), while a robo-advisor can provide more personalized portfolio management.

Let me narrow it down to the best fit

I can give you a more specific recommendation if you tell me one thing: does your small business have employees other than you (and possibly your spouse)?

That will help me identify the most suitable account type and compare the actual fees and automation features.

If you are looking for hands-off, automated retirement investing for your small business, the best choices depend on whether you are a solo entrepreneur (or self-employed with no employees) or a small business with a team.

Hands-off options range from pure digital robo-advisors to traditional brokerages with automated management features:

• Betterment for Business
  • Best For: Turnkey, automated 401(k) plans for small-to-medium teams.
  • How it works: Betterment offers a fully digital, fiduciary 401(k) platform that automates employee onboarding, investment selection via diversified ETF portfolios, and continuous auto-rebalancing. Employees get their own digital robo-advisor experience based on their target retirement age.
  • Learn more: Check out offerings on Betterment.
• Fidelity Go (with SEP-IRA or Solo 401k)
  • Best For: Solopreneurs or small teams wanting zero-to-low fee automated management.
  • How it works: While Fidelity's corporate 401(k) products require more administration, individual or self-employed accounts like a SEP-IRA or Solo 401(k) can leverage Fidelity Go , which is their digital robo-advisor. It handles portfolio building, automatic rebalancing, and ongoing monitoring for a low advisory fee (or $0 on balances under $25,000).
  • Learn more: Compare options via Fidelity Small Business Retirement Plans.fidelity.com+2
• Human Interest
  • Best For: Fully automated 401(k) administration and investing sync.
  • How it works: Human Interest integrates directly with popular payroll providers to automate contributions, compliance testing, and recordkeeping. It assigns participants diversified, automated portfolios, removing the burden of manual asset allocation from both the employer and the employee.
  • Learn more: Explore the platform on Human Interest.
• Schwab Intelligent Portfolios
  • Best For: Automated investing with no advisory program fees.
  • How it works: Similar to Fidelity, you can set up small business retirement structures and use Charles Schwab's automated algorithmic investing portfolios to handle rebalancing and risk alignment completely hands-off, with $0 advisory fees (though underlying ETFs have standard expense ratios).

To help narrow down the right choice, let me know:

• Do you have W-2 employees , or is it just you (self-employed)?
• Do you prefer a SEP IRA (simpler, employer-only contributions) or a 401(k) (allows employee salary deferrals)?

Yes. There are several platforms in the U.S. that offer fully automated, hands-off retirement investing for small business owners. The best option depends on whether you're self-employed, run a business with employees, or want to establish a company-sponsored 401(k).

The key distinction is between two types of automation:

• Investment automation: The platform chooses investments, manages your portfolio, and automatically rebalances it.
• Plan administration automation: The platform also helps handle payroll contributions, employee enrollment, compliance, and ongoing plan administration.

Some platforms offer both, while others automate only the investing.www.betterment.com+2

Best platforms to consider

• 

1. Fidelity — Best for self-employed owners

(Strong choice for solo businesses)

Fidelity offers a SEP IRA that can be managed using its Fidelity Go robo-advisor. The service selects investments based on your goals and risk tolerance, then handles portfolio management and rebalancing.www.fidelity.com+3

• Account: SEP IRA
• Investment fee: $0 under $25,000; 0.35% annually at $25,000 and above.
• Minimum to start investing: $10 with Fidelity Go.
• Best for: A self-employed owner or small business with employees eligible for a SEP IRA.

Important limitation: A SEP IRA allows employer contributions, not employee salary deferrals. Fidelity Go also does not eliminate your responsibility for making appropriate business contributions.

2. Betterment at Work — Best for an automated employee 401(k)

Betterment combines investment management with payroll integrations, automatic enrollment options, and substantial plan administration and compliance support. Employees can use professionally built portfolios instead of selecting and managing investments themselves.www.betterment.com+1

• Account: Employer-sponsored 401(k)
• Published Essential pricing: $100/month base fee, $5/month per participant, plus a 0.25% annual advisory fee.
• Setup fee: $500 for a new plan.
• Best for: Owners who want to provide a retirement benefit while minimizing administrative work.

This is more comprehensive than a standalone robo-advisor, but the employer still needs to make plan-level decisions and oversee the business's responsibilities.

4. Vestwell — Best for managed investment options within a broader plan

Vestwell offers workplace retirement plans with professional investment options, including managed-account and target-date-fund approaches in supported plans.

• Account: Employer-sponsored 401(k)
• Automation: Depends on plan configuration and selected services.
• Best for: Employers seeking flexibility and professional investment oversight.

Vestwell is not a single, uniform robo-advisor product, so ask which services your proposed plan actually includes.

Which type of account should you choose?

One important distinction: a target-date fund is also a hands-off investment option. It automatically adjusts its investment mix as you approach retirement, usually without a separate robo-advisor management fee. In a 401(k), this may be a simpler alternative to a separately managed portfolio.

Yes. Depending on whether you are a solo entrepreneur (no employees) or a growing small business (with staff), there are robust digital platforms designed to make retirement investing completely hands-off.

The market divides these automated solutions into two distinct categories: digital robo-advisors for solopreneurs and automated 401(k) platforms for companies with employees.

If you are flying solo and want hands-off portfolio management (automatic rebalancing, risk-aligned asset allocation, and algorithmic investing), digital robo-advisors support self-employed accounts like SEP IRAs and Traditional/Roth IRAs:

• Wealthfront : Well known for pioneering digital wealth management. Wealthfront allows self-employed individuals to open a SEP IRA alongside standard IRAs. Once funds are transferred, it completely automates your asset allocation, handles daily trading and rebalancing, and monitors for wash-sales at a low 0.25% advisory fee.wealthfront.com+2
• Betterment : Offers automated goal-based investing and supports SEP IRAs specifically for sole proprietors and single-participant plans (no employees). Betterment automatically invests your contributions into globally diversified, risk-adjusted ETF portfolios and handles all rebalancing automatically.betterment.com+2

If you have employees, a standard robo-advisor won't work because multi-participant plans require compliance testing, recordkeeping, and payroll integration. Instead, modern full-service providers fully automate both the administration and the employee investment choices:

• Human Interest : Ideal for small-to-medium businesses. It syncs directly with over 600 payroll providers to completely automate employee deductions, contribution mapping, and recordkeeping. For investments, it uses hands-off, low-cost model portfolios and target-date funds based on employee ages, while also taking on heavy fiduciary liability relief for the employer.humaninterest.com
• Guideline : Deeply integrated into modern platforms like Gusto, Guideline automates the entire lifecycle of a 401(k)—from employee onboarding and automatic enrollment to payroll deductions and compliance reporting. Employee funds are automatically invested in professionally managed, low-fee portfolios aligned with their target retirement date, requiring virtually zero day-to-day oversight from the business owner.guideline.com+1

To help me narrow down the best platform match, could you let me know:

• Do you have employees , or are you a solo business owner?
• Which type of account or structure you are leaning toward (e.g., SEP IRA, Solo 401(k), or a traditional group 401(k))?
