The Employer-Employee Relationship is Changing & Benefits are on the Chopping Block: Three Lessons from St. Louis

By Jim Hettenbach, VP, Unum Ventures

Last month, SixThirty convened LPs from across different parts of our ecosystem who wouldn't normally be at the same table, to tackle a problem that we're all going to face in the coming years: as the relationship between employers & employees changes, so will the benefits & security provided by employment. Unum, RGA, Edward Jones, Commerce Bank, and three of our portfolio companies working at the intersection of health, wealth, and AI participated in four hours of working sessions to pressure-test one question: if you were building the employee benefits system from scratch today, what would it look like?

We didn't get a final answer, and we weren't trying to. What we got was sharper than that: a room full of people who normally compete or sell to each other, agreeing on where the current system breaks, and disagreeing (productively) on what should replace it. Three lessons stood out.

SixThirty's portfolio companies played a key role in this room, each of whom is attacking this problem head-on, but who recognized that we will go further if we work together.

• Aegle : credit-based risk management that gives employers, at-risk providers, and health insurers a real alternative to traditional re/insurance.
• Angle Health : a full-stack, licensed health insurance carrier built for SMBs, running quoting, claims, and member care on a single modern platform instead of legacy, paper-heavy infrastructure.
• Candidly : turns student debt and retirement savings into a single employer benefit, closing the gap between paying down debt today and saving for the future.

1. Almost nothing about today's benefits system was actually designed

Half of U.S. households have zero retirement savings, 60% couldn't cover a $1,000 emergency, and 31% of student loan borrowers are now in default. None of that is bad luck - it's the output of a benefits system nobody actually designed.

Employer-sponsored health insurance exists because employers used it to compete for scarce labor under WWII-era wage controls, and the tax code later locked it in: exempt employer premiums from income tax, and every employer in America has a reason to offer a health plan. Coverage went from under 10% of Americans in the 1940s to roughly 165 million people on employer plans today, not because anyone decided that was the right design, but because the incentive never got revisited.

The 401(k) has the same origin story. It was a loophole a consultant named Ted Benna found in 1978, in tax language written for executive deferred compensation, not a retirement plan for the broader workforce. COBRA rode into law that same year inside an unrelated omnibus bill, with no strategic intent behind it. Even the small stuff traces back to arbitrary rulemaking: the FSA use-it-or-lose-it rule was loosened in 2013 specifically because the IRS got tired of people buying a third pair of glasses every December, and the first $50,000 of employer-paid group life insurance is tax-free for the same reason employer health premiums are.

None of this was a plan, and the seams still show today. Unum's own Market View Report on the benefits experience< /a>found that while more than 80% of employers say benefits matter to the employee experience, only 30% rate themselves as excellent at delivering the non-medical ones, and 72% think carriers, not employers, should be the ones handling bulk enrollment. That's a system's own operators telling you the plumbing is still visibly welded together.

AI is giving every institution in that room, insurer, reinsurer, bank, and startup alike, a reason to revisit the whole structure at the same moment, and that kind of simultaneous motivation across an entire industry doesn't happen often.

The pressure isn't just historical: provider consolidation since 2008 and certificate-of-need laws have been quietly driving up the cost curve for two decades, and reinsurers and stop-loss carriers are already shifting from traditional players to PE- and VC-backed entrants betting the market is about to move. A DOJ antitrust action against New York hospital systems is one more sign the old structure is cracking under its own weight. This isn't a system waiting for a good idea, it's one already coming apart.

And it's not just AI that is changing the nature of work, the returns to shareholders vs. returns to employees have flip-flopped over the last 30 years, with shareholders taking the outsize portion. What's unique about today is the ability to use technology, and AI specifically to redesign benefits, in a way that is intentional, from the ground up. 1978 may have been a year when many benefits were "accidentally" codified, but 2026-2027 could be the years when we build a new system, powered by technology, to enter a new age.

2. Portability isn't a nice-to-have anymore. It's the whole game

Median employee tenure has fallen to 3.9 years, the lowest since 2002, and workers under 35 are averaging closer to 3 years, against 9.6 years for workers over 50. Ten percent of Americans now work two jobs, the highest share since 2005, and roughly 43% do some form of gig or supplemental work. Stripe data cited in the room also showed solo-entrepreneurs billing $5 to $10 million a year have tripled in three years, evidence that AI is letting very small teams do far more without needing to hire, which decouples entrepreneurship from job creation in a waythe benefits system was never built to handle.

Meanwhile, 24% of Americans say they stay in a job specifically to keep their health coverage, up eight points in just five years. That's job lock, and it is getting worse, not better, even as the workforce itself becomes less tied to any single employer. This isn't a new observation inside the room, either: RGA has been publishing on this exact gap for years. Its own analysis on the gig economy and group benefits argues that independent workers are a large, underserved market that existing products fail, not because the need isn't there, but because the paperwork, medical evidence requirements, and rigid plan designs were all built for traditional employers, not individuals. While this has been a topic of conversation for some time (over seven years!), the message is more poignant now, and more urgent than ever before.

The room's sharpest ideas all pointed at the same fix, approached from different angles: a single portable retirement account that collapses the IRA, Roth, SEP, and 401(k) into one vehicle that travels with the worker regardless of employment status and has the same contribution levels available to everyone, removing the disadvantage that workers outside of ERISA face; providing health and protection benefits through the groups people belong to now, such as: PEOs, guilds, gig platforms, professional associations, instead of a single employer, and removing the penalty (increased cost) faced by those who access these benefits outside of their employer; and a health wallet concept, a portable personal health record and access that follows the person, not the job. The common thread is decoupling security from employment status, beyond just decoupling from any one employer.

3. No single institution can rebuild this alone

An insurer can redesign a product. A reinsurer can reprice risk. A bank can build the account. A wealth manager can build the advice layer and distribute a product. A startup can bring technology to the forefront & access to the masses. None of them can do all five, and none of them has a reason to convene the others. You can see the gaps being filled piecemeal already, including inside our own portfolio: Aegle is building credit-based risk management as an alternative to traditional reinsurance for employers and at-risk providers, and Angle Health is running an AI-first, full-stack licensed health carrier built to give SMBs the underwriting, claims, and member experience the legacy carriers never built for them. Each is solving one piece of the puzzle well. Neither is trying to solve all of it, because no single company reasonably can.

Litigation is reshaping the distribution layer at the same time, on two fronts: on the life and disability side, pay-to-play broker compensation structures are under scrutiny, and on the health side, employer fiduciary duty suits are emerging around stop-loss plan decisions. One plausible end state discussed in the room is employers stepping out of benefits administration altogether and simply handing employees a check. Consolidation is accelerating in parallel, with Aon's acquisition of USI landing on the heels of its NFP purchase, meaning fewer, larger intermediaries are absorbing the very distribution layer that used to leave room for new entrants.

Some of the best ideas from the day only work if multiple institutions move together:

• One proposal: a fiduciary standard for healthcare, a legal duty requiring doctors, insurers, or plan managers to put a patient's best medical and financial interests strictly ahead of their own profit, works best if providers, insurers, and reinsurers adopt it together. A single major holdout can undercut the incentive for everyone else.
• Another idea discussed, catastrophic coverage backstop needs government, insurers, and reinsurers all underwriting the same boundary line. These aren't ideas one company can pilot quietly and scale later. They require the builders and the participants agreeing on the shape of the thing before anyone commits capital to it.

Why we convene rooms like this

Because we're the one party in that room with a reason to get all of them talking to each other before any of them has to make a bet, and no financial stake in whose model wins. We aren't the insurer, the reinsurer, the bank, or the startup, but we care deeply about the world that we are all building together as venture capitalists, and are committed to working with the best and the brightest to achieve positive returns for society, alongside financial returns.

Jim Hettenbach, VP of Unum Ventures, said it plainly to the room: Unum invests across multiple funds, but no other firm can bring this specific group together the way SixThirty did that day. We're repeating that not because it's flattering, but because it's the actual argument for why sessions like this are the highest-leverage thing we can do for our portfolio and our partners.

We left with commitments, not just ideas, and a plan to reconvene on what an actual operating model could look like. More on that soon.
