About Alistair and Diffyn

In their own words, as submitted to SaaSHub.

Alistair
Diffyn

Advisors charge 1%. We don’t. Your financial well-being shouldn’t cost 1% of your future. On a $1M portfolio, that’s $10,000 every year. And for that fee, you’re often getting a quarterly phone call and a PDF of pie charts. Alistair gives you the same CFP-level expertise. No AUM fees. No...

Questions & Answers

As answered by people managing Alistair and Diffyn.

What makes your product unique?

Alistair's answer

There are 3 primary paths for managing your finances: - self manage with calculators, spreadsheets, and google queries. This can be particularly nerve-wracking AND time consuming for people new to personal finance. - pay a fee-only advisor $300-$500 per session to chat several times per year. You continue to self manage but you have an expert to guide you. - pay an advisor 1% of your total portfolio value to manage your finances on your behalf and chat with you 4x per year. Your finances are in good hands, but at what cost?

Alistair is here to provide you a reasonable alternative. Self manage your finances with Alistair to help guide you for less than it cost for a tank of gas. Nervous to ask about the difference between Roth and Trad IRA's? Alistair can explain the difference, any time you want, over and over again when you forget, wants you to learn about your finances, remembers ALL your financial details, don't require you to connect all your accounts, and doesn't cost a fortune.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

Alistair's answer

Competitors are either a disparate set of tools and calculators that don't talk to one another, or an exorbitantly priced advising business who you will only talk to 4x per year. Alistair is available 24/7, has passed a CFP-exam just like those other advisors, and won't cost you a fortune.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Which are the primary technologies used for building your product?

Alistair's answer

Next.js, Vercel, Supabase, DeepSeek.

Diffyn's answer:

React, Next.js, POSTGRESQL

How would you describe the primary audience of your product?

Alistair's answer

Growth-minded people interested in mastering their finances.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

Alistair's answer

My wife and I were using an LLM-centric workflow to manage our finances. We showed it to several friends who expressed interest in having something similar. We spent the next couple months productizing our own "process" into an app.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
