About
A small company that builds what it uses.
That Fellow Digital LLC is a New York company run by Gerald Mastro. We build websites that bring in customers, catch every lead in a CRM with its follow-up, and set up posting and reporting that runs the same way every week. We also make the Postwyre suite of products and tools like MastroSDR.
Several of our tools started inside Mastro Management, a company we work closely with, so a real team uses them before anyone else does. You talk to the people doing the work: no account manager relaying messages, no ticket queue.
“Everyone is selling time. You pay a plumber because you don’t want to take the time to go to school, be an apprentice and put in all the time required to be the person who gets called to a house for a plumbing job.”
“If you have enough time, energy and effort, you can do absolutely anything. But you can’t do everything. That’s why we do what we do best.”
So far
From client websites to the Postwyre suite.
- 2020 to 2022
Client websites. Sites for a pharmaceutical company, construction firms, a lender, clothing brands and a pizza shop, built on WordPress like most sites then.
- Early 2026
Our own software. We started building products of our own, beginning with Job Site Daily Report and MastroSDR.
- Aug 2026
Our own site, rebuilt. Off WordPress and onto a static build, from 1.4 MB a page to about 100 KB, with every old address redirected.
- Sep 2026
MastroCC goes to work. Mastro Management’s callers start recording and sorting their calls in it, and their lead queue runs from it.
- Oct 2026
Mastro Meet pilot. Video meetings with live captions, recaps and tracked action items, rolling out inside the same team.
- Now
The Postwyre suite. Postwyre, CRMwyre, Datawyre, Studiowyre, Meetwyre, Coldwyre, Callwyre and Saywyre: our own suite of products, from posting and lead follow-up to free dictation.
Ownership
Do you actually own your digital assets?
Your domain, your hosting, your analytics, your ad accounts. It is common to find a business whose domain is registered to a developer who stopped answering emails three years ago, or whose Google account is in a former employee's name.
That is a real risk, and it is invisible until the day it matters. Part of what we do is untangle it: work out who holds what, get it back into your name, and hand over the keys. You should be able to fire us and take everything with you.
Questions
What clients ask first.
Do you only build websites?
No. We also set up lead capture into a CRM with follow-up, and posting and reporting that runs the same way every week, and we can set them up on products from our own Postwyre suite. You can start with any one of them.
Can you redesign our site without taking it offline?
Yes, and this is the normal way we work. The replacement gets built on a staging address first, we check it properly, and only then does it cut over. DavosPharma is a good example: a working business site that was rebuilt and moved to new hosting with almost no downtime.
Do you offer ongoing maintenance?
Yes. The optional care plan covers small edits and updates whenever you need them, with priority support. Separately, Watch, part of Site Lockdown, checks your domain, DNS, email settings and site once a day and tells you the same day if something changed. Fixes are quoted first.
What happens after launch?
You get someone to call. A site is not finished when it launches. That is when people start using it, and things come up.
Still have a question?
Fifteen minutes, no pitch. Ask about a product, a website, or something you want built.
