Build Your Fintech Startup's Waitlist, Portal and Investor Dashboard with AI

Mythex builds the software a fintech team needs around its core product: a waitlist with referral positions, a portal that shows users where their onboarding stands, a CRM for design partners and a dashboard for the monthly investor update. You describe it in chat, check it in a live preview and publish it with a real database. Money movement and identity checks stay with the licensed providers you already use.

The tools a fintech team cobbles together before launch

Early fintech companies run on stitched-together tools. The waitlist sits in a form builder, onboarding status sits in the verification provider's dashboard, design partners live in a spreadsheet, and the investor update is rebuilt in slides every month from three exports. Users email support because they cannot see why their account is still pending. Business customers want usage invoices they can reconcile line by line. None of this is the regulated core of the product, which is why it gets neglected, and also why it is the part a small team can build and change quickly without touching the ledger or the licensed partner's systems.

What you can build for fintech startups

A waitlist that ranks signups by fit, not just by date

Each signup gets a referral link and a queue position that improves as friends join. One qualifying question, such as personal or business use and expected monthly volume, plus a country picker, lets you open access in batches to the people your licence actually covers. The thank-you page shows their place and what happens next.

Build a waitlist landing page for my fintech app. Ask for email, country, personal or business use and expected monthly volume. Give every signup a referral link and a queue position that moves up with each referral, and show it on the thank-you page. Add an admin view to filter signups by country and volume and invite a batch.

An onboarding portal that answers 'why am I still pending?'

Users log in and see their step: details submitted, verification pending, more information needed, approved. When a check stalls, the portal says what is missing in plain words. Business accounts add team members with roles, and developer customers get sandbox and live API keys kept apart, with support requests tied to their account.

Create a customer portal for my fintech startup. Show each user their onboarding step and a plain message when we need something from them. Let business accounts invite teammates as admin or viewer, show separate sandbox and live API keys for developers, and let users open support requests linked to their account.

A CRM that keeps pilots honest

Waitlist, trial and paying users share one record with a stage. Design partners and pilot customers get their own pipeline with a start date, an end date and a success metric, so you can tell an investor which pilots converted. Partner banks and investors are tracked separately, and interview notes link to the account they came from.

Make a CRM for a fintech startup with three pipelines: users from waitlist to paying, design partners with a pilot end date and success metric, and investors from intro to committed. Import my waitlist from CSV and merge duplicate emails. Link customer interview notes to each account.

The investor update, built once

Waitlist growth, activation from signup to verified user, onboarding drop-off by step, monthly active users, transaction volume, revenue, burn and runway, all on one page. Point it at CSV exports or a read-only copy of your data rather than the production database, and send the same charts every month.

Build a metrics dashboard for my fintech startup: waitlist signups per week, activation rate from signup to verified, drop-off at each onboarding step, monthly active users, transaction volume, revenue, burn and runway. I will upload CSV exports each month. Add login so only the team and investors can see it.

Usage invoices a finance team can check

Record API calls or transactions per customer and generate monthly invoices that show counts by day or endpoint, on top of a platform fee by plan tier. Enterprise contracts carry a minimum commitment, and outage credits appear as their own line. Card collection goes through a payment provider you connect under your own account.

Create invoicing for my API product. Store usage per customer per day and endpoint, charge a monthly platform fee by plan plus usage above the included amount, apply minimum commitments for enterprise accounts, and allow credit lines for outages. Each invoice should list the usage counts behind the charge.

An integrations directory with honest status labels

List the banks, accounting tools and platforms you connect with, each with what the integration does, how to set it up and a live, beta or coming-soon label. Filter by category and region. Coming-soon entries carry a notify-me button, which tells you which integration to build next.

Build an integrations directory for my fintech product. Each listing has a name, logo, category, regions, setup steps and a status of live, beta or coming soon. Add filters, a notify-me form on coming-soon listings, and a partner submission form that creates a draft for us to approve.

What to build yourself and what to leave to licensed providers

Build the marketing site, waitlist, onboarding status screens, internal CRM, invoicing for your platform fees and the metrics dashboard. Leave holding customer funds, card issuing, payments and identity verification to the regulated partners you contract with; your app can show their status and link to their flows. Financial products usually carry required disclosures and data protection duties, so check what applies to your product and markets with your compliance or legal advisers before launch. Mythex builds the app; it does not make it compliant for you.

Ask for login and per-account access checks on every page
Store uploaded documents in private storage, never public links
Point dashboards at exports or a read-only copy, not production

From three tools to one record per user

Start with the waitlist, since it is the first thing people see. Import the existing list from CSV, then add the CRM stages so each signup moves from waitlist to invited, verified and active in one place. Once that record exists, the onboarding portal and the investor dashboard read from it instead of from separate exports.

Questions

Can I build a fintech app without coding?

You can build the parts around the regulated core without coding: the website, waitlist, onboarding status portal, CRM, invoicing and dashboards. You describe them in chat and Mythex writes the code. Payments, card issuing and identity checks should run through licensed providers you connect with your own accounts.

Can Mythex handle KYC or identity verification?

Not by itself. Identity checks are done by a specialist provider you contract with; the app can show the user's status, guide them to the provider's flow and record the result. Check the verification requirements that apply where you operate.

Can we give the waitlist referral positions?

Yes. Ask for a unique referral link per signup and a queue position that improves with each referral. Confirmation emails need an email service you connect yourself.

Can our users get it as a phone app?

On Pro, Mythex can turn your published app into Android and iPhone apps that open your published app, so every Publish updates them. For a regulated banking app, your core product and its partners will usually have their own requirements.

How much does it cost?

Building and publishing works on the Free plan, which gives daily credits and needs no card. Pro is $25/month and adds code editing, export, GitHub and a custom domain, which most startups want before investors or users see the app.
