RiXtrema and Larkspur Data: A Fair Look at Larkspur Executive

A quick disambiguation before anything else, because the search results for this brand are a mess: Larkspur on its own is a flower and a town in Marin County. The retirement-plan product people mean is Larkspur Data, now owned by RiXtrema — and if you are comparing prospecting tools, that is the pairing to search for. This page covers what the product is, what RiXtrema has actually published about it, what is not published, and how it stacks against an alternative built for a different job. We build that alternative, so every factual claim below carries a source URL and a date, and where the only available numbers are eight years old we say so instead of dressing them up as current.

What is Larkspur Data, and how did RiXtrema end up with it?

RiXtrema announced the acquisition of Larkspur Data on February 1, 2018. The trade coverage describes Larkspur as a Novato, California retirement plan intelligence specialist, with a database covering more than 500,000 retirement plans and a plan-executive dataset reaching "1 million executives at hundreds of thousands of plans." Financial terms were not disclosed. RiXtrema founder and president Daniel Satchkov is quoted: "Acquiring Larkspur was a no-brainer decision for us. Not only will advisors be able to show significant plan savings using 401kFiduciaryOptimizer algorithms, but Larkspur's data will enable them to produce complete financial and legal diagnostics for any plan, including non-audited ones."

That quote is the clearest statement of the strategy anyone has published, and it tells you exactly what kind of company this is. RiXtrema is fundamentally an analytics firm — its own homepage headline reads "Win 401(k) plans & comply with fiduciary regulation" — and Larkspur gave it the underlying plan and contact data to run those analytics against. Data plus diagnostics, sold to advisors who want to walk into a sponsor meeting with a fee-savings argument and a fiduciary read. Source: rixtrema.com (observed 2026-09-13).

What does Larkspur Executive cover?

The most specific published coverage claims we could find come from RiXtrema's own blog: Larkspur Executive has "up-to-date information about 850K+ ERISA plans" and "gives you ways to contact more than 1.2 million plan executives."

Source: rixtrema.com/blog/larkspur-executive-infographic/ (as published 2018-11-14).

Read that date carefully, and note that it does not agree with the 500,000-plan figure from the acquisition coverage published nine months earlier. We are not going to pretend either number describes the product today — we found no coverage figure published any more recently than 2018, and RiXtrema's current product pages render their content entirely through JavaScript, which means there is no static page we could read and quote from. If coverage matters to your decision, ask the company directly for a current number and get it in writing. Anyone quoting you "850K plans" as a 2026 fact is repeating an eight-year-old blog post, ourselves included if we did not tell you the date.

How much does Larkspur Executive cost?

Per-seat, store-listed. RiXtrema's marketing pages carry no price table (checked 2026-09-13). Its online store, however, lists Larkspur Executive seats from $1,595 (Standard, with national access) to $4,995 (Pro Plus) per user per year. Source: rixtrema.com store listing (observed 2026-09-24).

That is not a criticism — per-seat pricing is completely standard for analytics platforms, and it lets a vendor fit the package to a large team in a way a fixed price cannot. It is simply a different buying experience, and you should know which one you are signing up for. If you are an enterprise that budgets annually and negotiates everything, a quote is normal. If you are a solo advisor who wants to see a number and decide this afternoon, RiXtrema's online store lists per-seat tiers.

What RiXtrema genuinely does well

Any comparison that concedes nothing to the incumbent is a comparison you should ignore, so here is the real list. Contact depth beyond the filing. A Form 5500 gives you a sponsor and a signer; a dedicated plan-executive dataset goes further, and for a team whose bottleneck is genuinely "I cannot reach a human," that depth is worth paying for. Analytics, not just data. The fee-optimization and fiduciary-diagnostic tooling is the part Satchkov led with in 2018, and it is a real differentiator against pure database vendors — walking into a meeting with a quantified savings argument is a different conversation than walking in with a filing printout. Longevity. Larkspur survived as an independent specialist long enough to be worth acquiring, and RiXtrema has kept the product line going for eight years since. In a niche this narrow, that is not nothing.

Where does a contact database stop helping?

A contact database answers who you can call. It is silent on who you should call, and in this market sequencing is close to the whole game. According to Sharon Pivirotto of 401kbestpractices.com, "90% or more of all plans you're introduced to won't have a need," with a typical sales cycle around nine months in the small-plan market, stretching to two years for larger plans. Work a list in alphabetical order and you eat that 90% one dial at a time — and a bigger contact file means a bigger 90%.

The frustrating part is that the demand is genuinely there. Fidelity, as reported by Fred Barstein at WealthManagement.com, found that 22% of plan sponsors were actively searching for a new advisor in 2023 and 37% had made a change over the prior twelve months, and a Fidelity survey covered by 401(k) Specialist put the share looking to change at 34% — roughly double the 2020 rate. Sponsors are deciding all the time. A static database cannot tell you which of your territory's plans are in that 22% right now, and neither can the filings alone: under DOL EFAST2 filing mechanics, Form 5500s are filed up to seven months after plan-year end with extensions to October 15, so the public record is typically 6 to 18 months old before anyone can search it. By the time a filing shows a change, the search is over.

How is FiduciarySignal different?

Full disclosure — this one is ours. It starts where the database ends: with the ordering question. The Change Predictor ranks the plans in a territory by the odds of a winnable provider change — trustee, custodian, recordkeeper or administrator — before it happens, and the 401(k) Report Card grades any plan from its own Form 5500 — administrative cost against genuinely comparable peers, participation, red flags, provider roster — so the flagged plan arrives with something specific to say about it.

The mechanism is the Pre-Switch Signal Stack: 25 distinct switch signals — eleven of them live feeds, timestamped and refreshed weekly rather than annually — layered on a model trained on 8.9 million Form 5500 filings across ten years and back-tested against the next year's Form 5500 filings. It is strongest at the top of the ranking. We do not publish which signals, and that is deliberate: every cue we print is a cue a copycat ships next quarter. What you get is the verdict and the reasoning, plan by plan — the recipe stays in the vault.

One honest caveat, because you would find it anyway: this is a work-the-top-of-the-list tool. The ranking is strongest at the top, the likelihoods are calibrated, and none of it is certainty. It will not predict any individual plan's future — no model can. It ranks so the first calls are the ones most likely to be worth making. Built on public DOL EFAST2 Form 5500 data.

Which tool should you choose?

Choose RiXtrema / Larkspur Executive if your bottleneck is reach and analysis — you want depth of plan-executive contact data beyond what a filing gives you, plus fee-optimization and fiduciary diagnostics you can put in front of a committee, with per-seat store pricing. Those are genuine strengths and no honest competitor should tell you otherwise.

Choose FiduciarySignal if your bottleneck is prioritization — you already know how to make calls, and what is missing is a defensible reason to call this plan before that one, refreshed weekly, on pricing you can read before you speak to anyone. A deeper Rolodex makes the haystack bigger. A ranked territory makes the needle findable. Work out which of those two you are short of, and buy that.
