Helmsman
A subscription AI that runs your money end to end, registered as an advisor.

Test it before you build it
$1,000 · 3 weeks · 25 prospects
For $1,000 in 3 weeks, this proves whether tech-forward households will put $50 down against a $25-a-month self-driving money manager before any code exists.
Riskiest assumption · Tech-forward US households, who have historically paid near zero for money software, will pay $25 a month - starting with $50 down today - for software that moves their money without asking, despite free bank tools and cheaper dashboards.
1Focus group: who and where
The household money-runner, age 25-45, working in tech or adjacent, with 3+ linked financial accounts, $5,000+ sitting in checking earning near zero, and a current or recently cancelled subscription to Rocket Money, Copilot Money or Monarch Money - someone already paying for money software and still doing the moving themselves.
where to find 25 · r/personalfinance and r/Bogleheads on Reddit (recruit from posts about idle cash and subscription creep); the App Store and Google Play review sections of Rocket Money, Copilot Money and Monarch Money (recruit reviewers who complain the app tells them what to do but does nothing); the YNAB Fans Facebook group; and Reddit ads targeted at those same subreddits to drive the priced page.
2Sell first, build later
A founding slot in the first 100-user cohort of Helmsman: automated cash sweep to 4%+ yield plus subscription cancellation and renegotiation across linked accounts, live within 120 days of the cohort filling, with a written scope of what the agent may do unattended.
the ask · $25 per month flat; founding members lock $20 per month for year one with a $50 refundable reservation
a real yes · A real yes is $50 charged to a card plus a signed unattended-authority scope. Upvotes, waitlist emails without a card, and 'I'd definitely try this' count for nothing.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Priced reservation page
$900 · 10 days
Put up a one-page site: Helmsman sweeps idle cash to 4%+ yield and cancels or renegotiates subscriptions without being asked, $25 a month flat, founding cohort of 100 at $20 a month locked for year one, reserved with a $50 refundable card payment. Drive roughly 800 visitors with $800 of Reddit ads on r/personalfinance and r/Bogleheads plus organic posts. One founder runs ads and answers every comment.
keep going if · 15 paid $50 reservations, at a rate of at least 2% of unique visitors
2. Complainer calls with a close
$100 · 14 days
Recruit 20 people who posted reviews or subreddit threads complaining that Rocket Money or Copilot still leaves the work to them. Run 20-minute calls on how they handle idle cash and recurring charges, then make the live offer and send the reservation link before hanging up. Both founders split the calls.
keep going if · 5 of 20 pay the $50 reservation on the call or within 48 hours
3. Unattended-authority scope test
$0 · 7 days
Send every reserver a one-page authorization scope listing exactly what Helmsman may do without asking: sweep checking cash above a floor, cancel named subscriptions, initiate refinance quotes. Ask them to check boxes and sign. This tests the trust ceiling behind the card's stated risk - whether people will grant autonomy, not just admire it.
keep going if · 10 of 15 reservers authorize unattended cash moves of $500 or more
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$50
per prospect, refundable
how · A $50 refundable reservation taken by card checkout directly on the landing page - for a self-serve consumer at $25 a month, the smallest honest measurement is money on a card today, not an email address; no invoice or signature fits this buyer. set up: Stripe Invoicing ↗
what it reserves · One of 100 founding slots, the $20-a-month price locked for year one, and first activation when cash sweep goes live
refund · Refundable in one click any time before the user links their first account, returned to the card in 5-7 business days.
target · 15 paid reservations from roughly 800 visitors and 20 calls within 21 days
before taking money · Until the RIA registration is effective, the team must not give personalized investment advice or touch any client money - the deposit may reserve a cohort slot only, and a securities lawyer should review the landing copy before it goes up.
Go: build it if
15+ $50 reservations at a 2%+ visitor-to-reservation rate, and 10+ reservers sign unattended authority for moves of $500+ - willingness to pay and willingness to delegate both confirmed.
Kill: stop if
Fewer than 5 reservations across 800+ visitors and 20 direct closes, or fewer than 3 of 15 reservers grant unattended authority - people will not pay, or will pay only for another dashboard, which free bank tools already are.

outreach message
Saw your review saying Rocket Money shows you the problem but leaves the moving to you. I'm building Helmsman, a flat-fee service registering as an investment advisor so it can actually execute: it sweeps idle checking cash to 4%+ yield and cancels or renegotiates subscriptions without being asked. $25 a month, no percentage fees. I'm picking 100 founding users before we write production code. Can I get 20 minutes this week to hear how you run your money and show you what the agent would do first?
landing page
Your money, run for you. Not another dashboard. $25 a month flat. Reserve a founding slot for $50, refundable, and lock $20 a month for year one. Reserve your slot - $50, fully refundable
deposit terms
Your $50 reserves one of 100 founding slots and locks your price at $20 a month for the first year (list price $25). It is fully refundable in one click any time before you link your first account, back on your card in 5-7 business days. Founding accounts go live with automated cash sweep and subscription renegotiation within 120 days of the cohort filling.

The idea in full
- What
- Helmsman is a flat-fee consumer subscription: an RIA-registered autonomous agent that moves idle cash to yield, refinances debt when rates move, cancels and renegotiates recurring charges, and rebalances across a user's linked accounts without being asked. The core is deep ML, decision models trained on cashflow trajectories rather than a chat wrapper, which is why the product takes one to two years to earn trust and revenue. It defines a new category, the self-driving money manager, distinct from both dashboards and human advisors.
- Why now
- The rails for agent-native money just arrived - Agentcard (yc S26) issues debit cards for AI agents and Standard Signal (yc X26) runs a hedge fund where AI executes every trade end to end - and with 72 new fintechs already in the 2026 cohort, none of them sells autonomous money management to consumers.
- Wedge: first customer and entry point
- US first: launch with a single high-frequency win, automated cash sweep plus subscription-bill renegotiation for tech-forward households, self-serve at a flat monthly price, then earn permission for larger moves.
- Path to 100x
- US consumer financial software subscriptions are a $1-10B market today, but category creation is the mechanism: the first trusted self-driving money manager at $25 a month across 5-10 million households is a $1.5-3B revenue business that also owns the switch point for every deposit, loan and card decision. The distribution moat compounds as Helmsman becomes the preinstalled finance agent inside consumer AI assistants, a default slot with room for one or two winners.
- Ceiling
- Consumers have historically paid little for money software, and free bank-sponsored copycats could hold willingness-to-pay near zero.
- Closest real companies, as the generator saw them
- Earlybird (graveyard) built an AI finance copilot for founders and died selling advice, not action; BEAM personalizes on the bank's side, not the consumer's. Helmsman holds the advisory registration and executes, which neither did.
- Main risk
- One publicized bad autonomous decision destroys consumer trust in the category before the company reaches scale.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
3/5
Owning the switch point for every household deposit is a power-law prize, but consumer willingness to pay $25 a month is historically near zero.
Bootstrapper
2/5
Consumers historically pay near zero for money software, and the card concedes free bank copycats hold willingness-to-pay down.
Operator
1/5
Consumers have never paid meaningfully for money software, and $25 a month competes with free bank-sponsored tools the card itself flags.
Technologist
2/5
Cash sweeps and bill renegotiation over linked accounts is orchestration a bank-sponsored copycat ships free, as the card itself concedes.
Risk
3/5
RIA registration and flat-fee consumer subscriptions spread customer risk, but execution depends on bank account links and one publicized bad autonomous trade.
trends
3/5
Agent payment rails like scoped tokens make an executing RIA agent newly plausible, but self-driving consumer money has been pitched and rejected since well before 2025.
