The 2026 Embedded Retirement Landscape: Human Interest Embedded, Alpaca IRA API, Vestwell PEP, and Subscription White-Label

Four ways to put a retirement account inside somebody else's product

Retirement moved into platforms in 2025 and 2026 the way payments did a decade earlier. If you run a benefits platform, an HR system, a payroll product, or a gig marketplace, at least four categories of provider now want to be the retirement layer inside your app. They are not interchangeable. Each serves a different worker, carries a different compliance load, and is paid a different way.

This article maps the four: recordkeeper-embedded 401(k) products, brokerage-infrastructure IRA APIs, pooled employer plans, and subscription white-label individual retirement. The Gigaverse benefits platform partnership sits in the fourth category, and the comparison below is meant to be fair to the other three.

Category one: recordkeeper-embedded 401(k)

Human Interest's Embedded Retirement product (https://humaninterest.com/solutions/embedded-retirement) is the clearest example. A payroll or HR platform integrates the recordkeeper's APIs and offers a full 401(k) to its employer customers from inside the platform. The recordkeeper handles plan documents, compliance testing, Form 5500, and investment lineup. The platform earns a partner fee and gets a stickier customer.

Who it serves: employers with W-2 employees. The product is a plan, and a plan needs a sponsor.

Who it does not serve: independent contractors paid through the same platform. They cannot participate in an employer's 401(k) because they are not employees, and the platform cannot enroll them without creating misclassification exposure.

Compensation model: typically a referral or revenue-sharing arrangement between the recordkeeper and the platform, subject to ERISA service-provider disclosure rules on the plan side. Requirements vary; check current partner terms.

Category two: brokerage-infrastructure IRA APIs

On May 13, 2026, Alpaca announced individual retirement accounts for its Trading API users (https://alpaca.markets/blog/alpaca-introduces-individual-retirement-accounts-for-trading-api-users). Fintech developers who already use Alpaca for brokerage accounts can now open Traditional and Roth IRAs programmatically.

Who it serves: any individual, including contractors, because an IRA has no employer requirement. This is the first category on the list that reaches 1099 workers directly.

What it leaves to you: almost everything above the account. An IRA API gives you account opening, funding, and trading. It does not compute how much a Schedule C filer can contribute, does not track SEP or Solo 401(k) limits, does not handle the Saver's Match mechanics, and does not give investment advice. A platform that builds on it must either become an adviser or leave the user to self-direct.

Compensation model: the platform is the broker-dealer's customer and pays per-account or per-activity fees. Passing referral compensation to third parties from a brokerage relationship runs into Exchange Act 15(a) and FINRA Rule 2040 if the payment tracks accounts or trades.

Category three: pooled employer plans

Vestwell launched a retirement solution for Amazon Delivery Service Partners on June 24, 2025 (https://www.vestwell.com/news/vestwell-launches-retirement-solution-for-amazon-delivery-service-partners). A pooled employer plan lets many unrelated small employers join a single 401(k) with one pooled plan provider handling administration.

Who it serves: the W-2 employees of participating employers. In the Amazon DSP case, that means the drivers who are employees of each DSP.

Who it does not serve: contractors working alongside those employees, or the many gig drivers on other platforms who are 1099 by design. PEPs reduce the cost of sponsoring a plan; they do not change who is eligible to participate.

Compensation model: plan-level fees, typically a mix of per-participant charges and asset-based fees paid from plan assets, disclosed under ERISA 408(b)(2).

Category four: subscription white-label individual retirement

The fourth category exists because the first three all stop at the W-2 line or stop at the account. Gigaverse is a subscription retirement app for 1099 workers offered under a partner's brand. The user pays a monthly or annual subscription. The partner provides distribution and, in a white-label deployment, its own front end. Gigaverse provides the contribution engine, the account, tracking, education, and the hand-off to the user's CPA.

Who it serves: individuals with self-employment income. MBO Partners counted 72.9 million independents in 2025, 5.6 million of them earning $100,000 or more (https://www.mbopartners.com/blog/press/2025-state-of-independence-reveals-growing-talent-strategy-for-business). Only 15 to 18 percent of self-employed people use a Solo 401(k) (https://www.solo401k.com/blog/solo401k-adoption-growth-statistics-usa).

What the account is today: a Roth IRA held at a FINRA/SIPC-member broker-dealer. Gigaverse opens Solo 401(k) and SEP IRA plans through its custodian partner, with applications open now, and provides the contribution math, tracking, and a year-end CPA hand-off alongside them, including the 2026 limits of $72,000 total, $80,000 at 50 and older, $24,500 employee deferral, and roughly 20 percent of net self-employment earnings for a SEP.

Compensation model, and why it is the way it is. Gigaverse pays partners either a share of subscription revenue on paid plans or a flat per-seat licence fee. It never pays per account opened, per deposit, per enrollee, or as basis points on assets. The reasons are legal rather than commercial: compensation that tracks account openings or deposits resembles transaction-based compensation under Exchange Act 15(a) and FINRA Rule 2040; an SEC-registered adviser cannot share advisory fees with unregistered parties; SEC Marketing Rule 206(4)-1 requires a written agreement and promoter disclosure to users when a partner is compensated more than $1,000 in twelve months for referrals; and several states require paid solicitors of advisory clients to register as investment adviser representatives. Every partner discloses the arrangement to users, and the same explanation is published on the how we make money page. Gigaverse is pursuing SEC RIA registration.

Choosing among the four

A practical decision rule for a platform product manager:

• •If your users are employers with W-2 staff and you want a full 401(k) inside your product, category one or three fits, and the choice between them is mostly about plan-level cost and whether your employers want their own plan or a pooled one.
• •If you want to build your own retirement experience from primitives and are prepared to own the advice question, category two gives you the account layer.
• •If your users are individuals with 1099 income and you want a finished product under your brand without charging anyone on assets, category four is the only one designed for them.

Many platforms will end up with two: a plan product for employer customers and a white-label individual product for the contractors those employers pay. The two do not conflict, because they serve different people.

Two details that trip up integrations

The Saver's Match. Beginning January 1, 2027, the Treasury will match up to $1,000 of retirement contributions for lower-income savers, with MAGI phase-outs of $20,500 to $35,500 single, $30,750 to $53,250 head of household, and $41,000 to $71,000 joint. Roth contributions earn the match, but the payment must land in a non-Roth IRA under §6433(e)(2)(A)(ii). IRS Notice 2026-48 (August 7, 2026) invited comments through October 5, 2026. Any individual-account product will need a place for that payment to land; the mechanics are on the Saver's Match Roth rule page.

Contribution math is the product. For a W-2 employee, the platform already knows gross pay and the deferral is a percentage of it. For a contractor, the deductible contribution depends on net earnings after expenses and half of self-employment tax, and the user often does not know that number until January. Gigaverse's free tools show what the engine computes from a running Schedule C estimate.

Where Gigaverse fits

Gigaverse is the subscription white-label option in the map above: a retirement app for 1099 workers that today offers a Roth IRA through a FINRA/SIPC-member broker-dealer, plans Solo 401(k) and SEP rails, and in the meantime provides the contribution math, tracking, and CPA hand-off for those plans. It is pursuing SEC RIA registration, does not guarantee returns, and neither charges nor pays anyone a percentage of assets. Partners receive subscription revenue share or a flat per-seat licence, with the required disclosures built in. Integration details are on the benefits platform partner page.
