"I’m lucky to have found such a fantastic team."

Owner, Brooklyn Robot Foundry

To help a robotics academy adapt to online classes, CoSpark (formerly AnnexCore) updated its website and is now conducting a frontend redesign. The team also added a new booking system that collects information and payments.

Thanks to their extensive development knowledge, CoSpark (formerly AnnexCore) has upgraded the website to be functional and high-quality. To maintain a cost-effective price, the team uses creative solutions that allow them to work efficiently. The client is ecstatic with the invaluable expertise they provide.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the owner of a company called Brooklyn Robot Foundry. We teach robot building and basic engineering classes to kids and adults.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with AnnexCore?

Before the pandemic, our business was all in person. We're located in New York City, where we had four locations where kids would come and build robots. Up until the pandemic, we got all of our business basically by word of mouth. We had a website, but it didn't matter what it looked like because everyone who heard about our reputation wanted to come. It was an easy way to bring in customers.

Unfortunately, we had to stop having in-person classes when the COVID-19 pandemic hit. In response to the situation, we pivoted instantaneously to how we can ship products directly to customers and then create the robots together through live Zoom classes. This strategy allowed us to expand our services outside of our local area, and this meant that our website mattered a lot more because that’s where we had to sell ourselves.

I initially worked on the development on my own — I created an e-commerce site and connected it to our existing WordPress site. I had to handle it to survive as a business, but I wasn’t good at it as my expertise was in mechanical engineer. It was functional, but it was clunky and needed software updates. It also wasn’t beautiful, and we were too busy to focus on it, so we hired AnnexCore.

SOLUTION

What was the scope of their involvement?

AnnexCore took over our web development efforts. They updated all of our plug-ins and did some repairs that we couldn’t do. They leveraged and expanded on our existing plug-ins technologies rather than building something from the ground up, which would’ve taken longer. They also ended up taking care of web hosting. We initially used a different provider, but we weren’t getting much uptime with them.

It now has a teacher dashboard and functionality that will allow people from all over the world to take our classes. Our previous booking system was only for in-person lessons, which was a very different model. This new system allows us to collect registration information and payments for our online classes.

They’re currently redoing our site entirely, starting with a frontend redesign. Our main goal is to figure out how to make the website look cool, like how we make our locations look interesting to get customers.

We now have them on a monthly retainer and assign the deliverables we need. Aside from the main project scope, we also bring them into our meetings with one of our larger partners. We plan on giving them a whole lot more work in the future.

What is the team composition?

Carl (Project Manager) is our main point of contact, but we also have worked with some of their developers, led by Phil (Front-End Developer). We also work with Heral (Managing Director), who we talk to about finances.

How did you come to work with AnnexCore?

I found AnnexCore through a Google search. I was looking for WordPress e-commerce developers, and they had good reviews.

How much have you invested with them?

We’ve spent over $50,000. Their monthly retainer is $5,000.

What is the status of this engagement?

We started working together in August 2020, and it’s ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

They’ve done a great job; the website is exactly what we needed and more. From the beginning, it's been a remarkable experience. All of the developers on their team have been exceptionally good. They catch things we can’t even see, and their work is very detailed. They have a vast knowledge base when it comes to development.

It’s also been amazing that we can pull their team into our calls with our partners, especially when we’re having technical discussions. We’re so glad to have them aboard — they make us look like a strong team. When partnering with large companies, their team gives us more confidence.

How did AnnexCore perform from a project management standpoint?

Working with them is magical — they accomplish tasks quickly and intelligently. I’d be in a call with Carl, and as I’m talking to him, the team is already doing what we need in real-time. They often finish tasks instantaneously. They’re also such a transparent and trustworthy team. They take accountability for any mistakes, which we appreciate. Their personalities are lovely, and they’re highly intelligent. Our conversations are enjoyable and pleasant. I’m lucky to have found such a fantastic team.

What did you find most impressive about them?

Their creativity is amazing. AnnexCore is very good at listening to the nuances of the issues we deal with and then coming up with incredibly unique solutions that are also very cost-effective. The team is exceptionally thoughtful about budgets — we’ve never felt like they ever wasted our money.

The other thing is service contracts are flexible — they let us start small and ramp up when we were ready. We’re a small business, and they’re very conscientious about that. Annexcore understands that we’re constantly figuring out ways to pivot our business and try to help us. Their flexibility allowed us to have a multiphase project, which they blew out of the park.

Are there any areas they could improve?

Not at the moment. They’re an exceptional team, and I rate them highly.

Do you have any advice for potential customers?

Call a vendor’s references before hiring them to make sure that they’re a good fit. Then, conduct a test run with them. This was our strategy with AnnexCore, and it worked well. I highly recommend them to everybody.

CoSpark (formerly AnnexCore) was tasked with establishing an API software for a utilities service company. The vendor shares their prime service to make adjustments throughout the process.

The partners ran the processes within a few weeks into their partnership.

Although, they would have benefitted more from creating a portal for sharing large files.

One person.
