# The best 401(k) prospecting platforms in 2026: one platform, or a stack of tools?

Source: https://www.401khunter.com/best-401k-prospecting-platforms · Updated September 17, 2026 · By Jake, Founder, 401kHunter

A 401(k) prospecting platform does more than search filings: it carries you from a list of plans to a conversation. That means the plan data, the decision maker's contact details, the outreach and the follow-up in one place. The alternative is a stack — a Form 5500 database, a general contact database, a writing tool and a CRM, bought separately. This page compares the platforms, then prices the stack, so you can see which is cheaper for the way you work.

## Key takeaways

- 401kHunter is the most complete self-serve 401(k) prospecting platform: search, A–D fee grades, provider identification, decision-maker contacts, AI outreach, pipeline and client-ready reports, for $100/month or pay-as-you-go from $25.
- RiXtrema Larkspur Executive is the platform for high-volume email: campaign automation is built in from the $3,495/year Pro tier.
- Judy Diamond Prospector+ is a research-and-reports platform; AdvizorPro and ISS MarketPro are distribution-intelligence platforms sold by quote.
- A do-it-yourself stack starts with a filing database at $795–$3,900 a year at published prices, before the contact database, CRM and sequencer.

## What makes something a platform rather than a database

A database answers "which plans match these filters". A platform answers "who do I call tomorrow, what do I say, and did I follow up". In practice that is five capabilities: plan search with a reason to call attached (fees, red flags, provider); the current decision maker with a way to reach them; outreach that uses the plan's own numbers; a pipeline so prospects do not fall through; and a report you can put in front of the sponsor once they take the meeting.

Few products do all five. That is not a flaw if you already own a CRM and a sequencer you like — but it changes the comparison, because then you are buying a component, not a platform.

- Search + a reason to call: all platforms here; depth varies with how much data is joined to the filing.
- Decision-maker contacts: 401kHunter (on demand, confidence-scored), Larkspur Executive (pre-built file), AdvizorPro (plan contacts).
- Outreach: 401kHunter drafts plan-specific emails in your voice as a four-email sequence; Larkspur sends campaigns from inside the product; Judy Diamond supplies template letters.
- Pipeline: 401kHunter has stages, notes, an outreach log and reminders; the others export to your CRM.
- Sponsor-facing reports: 401kHunter (benchmark and white-label reports), Judy Diamond (scorecards), John Hancock (co-branded scouting reports).

## How we compared them

We build one of the products on this page, so treat our ranking as a vendor's view and check it against the sources. To make that easy, every competitor number below is that vendor's own published claim, linked to the page we read it on and dated to the month we read it. Where a vendor does not publish something — a price, a contact count — we say "not published" rather than estimate it.

We compared on five things an advisor actually feels: how much data is joined to each plan, whether the tool finds a person to call, whether it helps you write to them, what it costs to start, and how fast you can start. We did not score on features no vendor documents publicly.

- Data breadth: Form 5500 alone, or filings joined with other public sources?
- Contacts: a pre-built file, on-demand lookup, or none — and is confidence disclosed?
- Outreach: does the tool help produce the first message, or stop at the list?
- Price and terms: published or quote-only; monthly or annual; per seat or usage.
- Time to first list: self-serve signup, or a demo and a contract first?

## 1. 401kHunter

Self-serve 401(k) prospecting software that joins Form 5500 filings with 15+ other public sources, grades every plan's fees A–D, finds the decision maker, and drafts the outreach — with published pay-as-you-go pricing.

**Best for:** Advisors and small teams who want the whole prospecting workflow — find the plan, find the person, send the first email — in one tool, without an annual contract.

**Pricing:** Free search and 50 free credits; credit packs from $25; Pro $100/month incl. 1,500 credits. No contract. (source: https://www.401khunter.com/pricing, retrieved Sep 2026)

**Where it wins:** Breadth of joined data, decision-maker contacts and AI outreach in one self-serve product, at a published price a solo advisor can start on for $25.

**Pros**

- 15+ public sources joined to each plan, not Form 5500 alone: Schedule C provider pay, Schedule H/I financials, audit reports, SEC 11-K filings, IRS pre-approved plan lists, OSHA, IRS 990 and FMCSA headcounts, and more
- A–D fee grade and basis-point fee estimate on every gradable plan, with peer benchmarks by plan size and industry
- Identifies the provider even for small plans that file no Schedule C: named administrator, inferred recordkeeper, and the firm behind the IRS plan document (on file for about 85% of small plans)
- Decision-maker contacts on demand, each with a confidence score; credits are refunded automatically when no usable contact is found
- AI outreach in the advisor's own voice: a plan-specific brief and a four-email follow-up sequence
- 1.08M businesses with no ERISA-filed plan on record, for startup-plan prospecting
- Searchable red flags and change signals (late deposits, sponsor changes, high separated-participant share, excessive distributions)
- Client-ready and white-label benchmarking reports; built-in pipeline, notes and follow-up reminders; CSV export
- Search is free and open without an account; pricing is published

**Cons**

- Newer product with less brand recognition in enterprise procurement than the 40-year incumbents
- Contacts are found on demand per plan rather than shipped as a pre-built national contact file
- No public API yet
- Sends no email itself: outreach is drafted for you to send from your own mailbox or sequencer

## 2. RiXtrema — Larkspur Executive

A 401(k) plan database with a large executive contact file, fund-menu breakdowns and, on higher tiers, built-in trackable letters and automated email campaigns.

**Best for:** Teams that want a pre-built executive contact file and bulk email campaigns inside the same product.

**Pricing:** Per user per year: Standard $1,595; CTML $2,295; Pro $3,495; Pro+ $4,995 (source: https://rixtrema.net/larkspurexecutive/landingpage, retrieved Sep 2026)

**Where it wins:** Outreach at volume. The Pro tier runs automated email campaigns to plan executives from inside the product (up to 300 simultaneous campaigns, per the vendor), and its published contact file is the largest of any tool here.

**Pros**

- Largest published executive contact count
- Fund-menu (investment lineup) breakdown for 80,000+ plans
- Built-in trackable marketing letters and automated email campaigns on higher tiers
- Published tier pricing

**Cons**

- Annual per-user licence from $1,595; campaign automation starts at $3,495
- A pre-built contact file ages between refreshes; no per-contact confidence score is published
- Mass email to plan executives carries deliverability and compliance risk that the sender owns

## 3. Judy Diamond Associates — Retirement Plan Prospector+

The long-standing Form 5500 prospecting database, sold as single-state, regional or national annual subscriptions, with plan scorecards, red flags and benchmarking reports.

**Best for:** Advisors who work one state and want a mature, report-heavy Form 5500 tool with the deepest filter set.

**Pricing:** National $3,900/yr; regional editions $2,500/yr; single states $795–$995/yr (single user) (source: https://store.judydiamond.com/prospector-plus/prospector.html, retrieved Sep 2026)

**Where it wins:** Filter depth and printable plan reports. 500+ search fields, plan scorecards against national, state and industry peers, and pre-written marketing letters are more report tooling than any newer product offers. Per-state pricing is also the cheapest published way to cover a single state for a full year.

**Pros**

- 500+ search fields and over a dozen red-flag indicators
- Plan scorecards benchmarked against the country, the state and the same industry
- Pre-generated talking points and a dozen marketing letters
- Published, self-serve per-state pricing
- Decades of brand recognition with broker-dealers

**Cons**

- Annual subscription; national coverage is $3,900/yr per user
- No published decision-maker contact count, and no built-in contact enrichment by email and direct phone
- Form 5500-centred: no joined workforce, SEC or IRS plan-document data
- Now owned by Touchpoint Markets (spun out of ALM in 2025)

## 4. AdvizorPro — PlanPro

A retirement-plan data module inside AdvizorPro's wider advisor, RIA and firm intelligence platform.

**Best for:** Asset managers, wholesalers and larger RIAs that need plan data connected to an advisor and firm database.

**Pricing:** Not published — demo and quote only (source: https://www.advizorpro.com/data/planpro, retrieved Sep 2026)

**Where it wins:** Context beyond the plan. If the question is "which advisors and firms are attached to these plans, and who else do they work with", PlanPro sits inside a database built to answer it.

**Pros**

- Plan data linked to an advisor, RIA and family-office database
- Service-provider mapping and plan filing alerts
- Investment lineup data

**Cons**

- No published pricing; sales-led purchase
- Built for distribution and enterprise teams more than for a solo advisor

## 5. O3 Edge

A cloud prospecting platform from actuarial consultancy October Three, covering defined-benefit as well as defined-contribution plans.

**Best for:** Advisors prospecting pension, cash-balance and other defined-benefit plans.

**Pricing:** Annual subscription per licence; amount not published (source: https://www.o3edge.com/features/, retrieved Sep 2026)

**Where it wins:** Defined-benefit expertise. It comes from an actuarial firm and matches each subscriber with a plan expert, which matters when the prospect is a pension rather than a 401(k).

**Pros**

- Defined-benefit and cash-balance insight
- Ten-year plan analytics
- Plan-expert matching

**Cons**

- No published price
- No published contact data

## 6. John Hancock Prospect Finder

A plan-prospecting dashboard John Hancock Retirement provides to financial professionals inside its own portal, launched in July 2022.

**Best for:** Advisors who already place business with John Hancock and want prospecting inside that portal.

**Pricing:** No price published; access is through the John Hancock financial-professional login (source: https://www.prnewswire.com/news-releases/john-hancock-retirement-launches-prospect-finder-tool-for-financial-professionals-to-help-build-scale-and-efficiency-301593780.html, retrieved Sep 2026)

**Where it wins:** Cost and convenience for John Hancock producers: smart filters, co-branded scouting-report PDFs and peer comparisons with no separate subscription named.

**Pros**

- Co-branded scouting reports
- State, industry and national plan-score comparisons
- No separate price named

**Cons**

- Tied to one recordkeeper's portal
- Data source, plan count and contact data are not published

## 7. ISS MarketPro (BrightScope)

BrightScope is now the data engine inside ISS Market Intelligence's MarketPro suite, sold to institutions for defined-contribution market intelligence.

**Best for:** Asset managers, insurers and recordkeepers mapping advisor-to-plan relationships for distribution.

**Pricing:** Not published — enterprise quote only (source: https://www.issmarketintelligence.com/solutions/marketpro/, retrieved Sep 2026)

**Where it wins:** Institutional distribution intelligence: seeing which advisors serve which plans across the market. It is a different job from advisor prospecting, and brightscope.com no longer serves a public plan lookup.

**Pros**

- Advisor-to-plan relationship mapping
- Institutional-grade market and distribution analytics

**Cons**

- Not sold to individual advisors
- No published pricing
- The public BrightScope plan lookup now redirects to ISS

## Pricing the alternative: a do-it-yourself stack

Plenty of advisors assemble their own. The usual parts are a Form 5500 database, a general business contact database for emails and phone numbers, a CRM, and optionally an email sequencer. Using published prices (Sep 2026), the filing database alone is $3,900 a year for Judy Diamond's national edition, $1,595 for RiXtrema's Standard tier, or $795–$995 for a single state. A general contact database, sold by seat or by credit, and any paid CRM or sequencer tier come on top of that; price those for your own usage, because they vary widely. Then add the time spent moving lists between tools and matching a filing's signer to a current employee by hand.

The stack has real advantages. You keep tools you already know, a general contact database covers prospects beyond retirement plans, and nothing locks you in. Its weakness is the join: a general contact database does not know which person at the company oversees the 401(k), and a filing database does not know whether the signer still works there.

401kHunter's route costs $100 a month on Pro ($1,200 a year) including 1,500 credits monthly, or nothing until you unlock something on pay-as-you-go. The join is the product: it looks for the person responsible for the plan at that sponsor, scores its confidence, and refunds the credits if it cannot find a usable contact.


## Why "how much data" is the real difference

Every tool here starts from the same public record: the Form 5500 that retirement plans file each year with the Department of Labor. The filing tells you plan assets, participants, contributions and, for larger plans, what each service provider was paid on Schedule C. If two tools only reformat that filing, they differ mainly in filters and price.

The gap opens when a tool joins other records to the filing. A small plan files the short Form 5500-SF, which has no Schedule C, so a filing-only tool cannot tell you who the recordkeeper or TPA is for most of the roughly 800,000 small plans in the country. 401kHunter closes that gap by matching each small plan's IRS opinion-letter serial number against the IRS list of pre-approved plan documents, which identifies the firm behind the plan document for about 85% of small plans, and by inferring the recordkeeper from plans on the same document that later disclosed one. Audited financial statements and SEC 11-K filings supply Roth and plan-design facts the 5500 has no box for. OSHA, IRS 990 and FMCSA records supply current headcounts. 1.08M businesses with payroll but no ERISA-filed plan come from SBA and SEC records.

Of the 833,851 U.S. retirement plans with enough fee data to grade, 10.2% earn a D (reported administrative expenses above 1.5% of plan assets) and 60.9% earn an A (0.5% or less), per 401kHunter's analysis of Form 5500 filings as of August 2026.


## Which platform fits which firm

Matched by how the firm actually sells.

- Independent advisor or small RIA building a retirement-plan book: 401kHunter.
- Team running outbound email at volume to plan executives: Larkspur Executive Pro or Pro+.
- Advisor whose process is a printed scorecard mailed to a sponsor: Judy Diamond Prospector+.
- Asset manager, DCIO wholesaler or recordkeeper mapping advisors to plans: AdvizorPro PlanPro or ISS MarketPro.
- Actuarial or pension-focused practice: O3 Edge.
- John Hancock producer: start with Prospect Finder, add a platform when you outgrow one recordkeeper's view.

## Conclusion

A platform is worth it when the join between plan, person and message is where your time goes — which, for most advisors prospecting retirement plans, it is. 401kHunter is the most complete self-serve platform and the only one here with a published monthly price and pay-as-you-go entry; Larkspur Executive is the choice when in-product bulk email is the requirement. If you already run a contact database and a sequencer you trust, buying a filing database as a component is a reasonable alternative — price it honestly against the platform before you decide.

## Frequently asked questions

### What is the best 401(k) prospecting platform?

401kHunter is the best 401(k) prospecting platform for independent advisors and small teams: it combines 1M+ plans from 15+ joined public sources, A–D fee grades, provider identification, confidence-scored decision-maker contacts, AI outreach, a pipeline and client-ready reports, at $100/month or pay-as-you-go from $25. RiXtrema Larkspur Executive is the best platform for in-product bulk email campaigns, and AdvizorPro or ISS MarketPro for enterprise distribution teams.

### What is a 401(k) prospecting platform?

Software that covers the whole retirement-plan prospecting workflow rather than only searching filings: finding plans with a reason to call, identifying and contacting the decision maker, producing plan-specific outreach, tracking the pipeline, and generating a report for the sponsor.

### Is a platform cheaper than buying separate tools?

Usually, for retirement-plan prospecting. A national Form 5500 licence alone is $1,595–$3,900 a year at published prices, before a contact database and sequencer. 401kHunter Pro is $1,200 a year including contact lookups, and pay-as-you-go starts at $25. A stack can still make sense if you already own the other tools and prospect beyond retirement plans.

### Which platforms send email for me?

RiXtrema Larkspur Executive sends automated campaigns from its Pro tier ($3,495/year). 401kHunter drafts a plan-specific four-email sequence in your voice and reminds you to follow up, but you send from your own mailbox, which keeps deliverability and compliance review in your hands.

### Which platform is best for a broker-dealer or large RIA?

It depends on the job. For advisor-level prospecting across many reps, 401kHunter and Judy Diamond both publish their prices; 401kHunter also offers an Enterprise arrangement for teams. For home-office distribution intelligence — which advisors serve which plans — AdvizorPro and ISS MarketPro are the purpose-built options.

### Can I try a platform before paying?

401kHunter's search is free without an account and signup includes 50 free credits. Most others require a demo; Judy Diamond's store is self-serve but paid.

### Do platforms integrate with my CRM?

401kHunter, Judy Diamond, O3 Edge and AdvizorPro all offer CRM-friendly CSV export. 401kHunter also has its own pipeline if you would rather not run a separate CRM for plan prospects.

### How is contact data kept accurate?

Pre-built contact files age between refreshes. 401kHunter looks the contact up at the moment you ask, checks the person against the sponsor's company domain, returns a confidence score, and refunds the credits when it cannot find a usable contact. It does not describe contacts as verified.
