QuantRidge vs Tiller
Your finances fed automatically into Google Sheets or Excel.
What each one is for
People who want a spreadsheet and own their data outright. Nothing else gives you this much control over the model, and if you already think in spreadsheets it is hard to beat.
Running a taxable portfolio with the tax consequences attached — cost basis across every account, wash-sale warnings before the repurchase, harvestable losses, Roth conversion room against bracket thresholds, and a Form 8949 your preparer can file from.
Choose Tiller if
You want to build it yourself and keep the file.
We would rather say that here than have you find it out a month after subscribing to the wrong thing.
Where QuantRidge differs
Tiller hands you rows and a blank sheet. QuantRidge brings the engines already built — wash-sale detection, bracket-aware conversions, Form 8949 output — which is the part that takes months to write yourself and years to keep current with the rules.
The thing Tiller cannot offer
Tiller is the honest exception here: it puts your data in a spreadsheet and you extend it yourself, so in principle it can do anything. The difference is who does the building — with Tiller the formula is your problem, and with us the feature is ours.
QuantRidge is small enough that one person's problem can become a feature. The Founding 50 is built around exactly that: 50 accounts at $40/month for 12 months, in exchange for telling us what is missing. We build it and you watch it ship. Month 13 renews at $175, which we would rather say here than in a footnote.
Questions people ask
Is QuantRidge a replacement for Tiller?
Not always, and this page says where it is not. You want to build it yourself and keep the file. If that describes you, Tiller is the better choice and plenty of people run both.
What does QuantRidge cost?
$175 a month for individuals, flat, with a 14-day free trial and no percentage of your assets. A limited Founding 50 offer is open: the next 50 approved accounts pay $40/month for 12 months, then renew at the $175 list price.
Can I run QuantRidge and Tiller together?
Yes, and for some people that is the right setup rather than a compromise. What Tiller is for: People who want a spreadsheet and own their data outright. Nothing else gives you this much control over the model, and if you already think in spreadsheets it is hard to beat. QuantRidge connects to brokerages read-only and does not touch anything Tiller is doing, so running both costs you nothing beyond the second subscription.
Does QuantRidge manage my money?
No. QuantRidge is software, not a Registered Investment Adviser, broker or custodian. Brokerage connections are read-only — it can see positions and transactions but cannot trade or move money. Your money stays where it is.
