How Let’s Plan is Changing the Face of Mortgage Banking with Built Mighty

Built Mighty is the best, hands down.

Whatever you want to build, they’ll build it. And they’ll guide you through the entire process.

About Let’s Plan

Let’s Plan secure online software tools streamline workflows for mortgage loan officers and help homebuyers settle on their best loan options quickly and confidently.



While the average loan officer closes at a rate of 22%, Let’s Plan founder Steve Dellario averages 84%.

He attributes his success largely to a spreadsheet he’s refined over the course of his career to make the loan process more transparent and customer-friendly.

Where the typical loan officer asks homebuyers to jump through a series of hoops before receiving a final verdict, Steve enters his customers’ financial information into his spreadsheet to show them a complete breakdown of the fees and mortgage options before they ever fill out an application.

Thanks to this approach, Steve’s business has grown like wildfire on referrals alone.

He knew that if more loan officers had access to this tool, it could completely transform the industry.

He just needed the right team to bring his vision to life.

The tool was just an Excel spreadsheet

...and didn’t have the level of professionalism I needed. I wanted to usher in a completely new way of banking.

The solution


Steve immediately felt confident in Built Mighty’s knowledge and relied on their expertise to guide him through the product creation process, from ideation and fact-finding to requirements gathering.

I’d never done this before

...and I felt like I was in the right place around honest people. I felt taken care of, like they had my back.

With a roadmap in place, Built Mighty got started building a scalable web application that any loan officer could use with potential homebuyers.

First, Built Mighty worked closely with Steve to translate his Excel formulas into code that would provide a complete financial picture for customers.

From there, Built Mighty created a library that would save a PDF report for each session, allowing customers to review their results and compare any future rates.

Finally, Built Mighty brought in a design resource to elevate the look and feel of the final product.

Built Mighty had great buy-in.

I felt throughout the whole process that they were engaged and saw the value in my product. They were even able to coach me about what I would need in the future.



The Let’s Plan Loan Planner is now live and available to loan officers nationwide for a monthly subscription fee.

With a projected gain of 30,000-50,000 users in one year, it will bring in at least $18 million in revenue, give homebuyers a better banking experience, and improve loan officers’ success rates.

Several banks have already endorsed and begun promoting the tool, and interest continues to grow.

They immediately see the value

When I bring this product to the heads of banks and companies, they immediately see the value

Now, Steve is working on building out a whole suite of Let’s Plan products with Built Mighty, including Let’s Plan Calculator, a free home loan calculator available to the public, and Let’s Plan File Flow, a system for managing the entire loan application process.

I couldn’t have done it without them.

Built Mighty has helped create and bring to market the system I’ve used to get to this point in my career.
