With more and more electric vehicles on the road, existing electrical grid infrastructure needs to be able to keep up. Houston-based Revterra has the technology to help.

"One of the challenges with electric vehicle adoption is we're going to need a lot of charging stations to quickly charge electric cars," Ben Jawdat, CEO and founder of Revterra, says on the Houston Innovators Podcast. "People are familiar with filling their gas tank in a few minutes, so an experience similar to that is what people are looking for."

To charge an EV in ten minutes is about 350 kilowatts of power, and, as Jawdat explains, if several of these charges are happening at the same time, it puts a tremendous strain on the electric grid. Building the infrastructure needed to support this type of charging would be a huge project, but Jawdat says he thought of a more turnkey solution.

Revterra created a kinetic energy storage system that enables rapid EV charging. The technology pulls from the grid, but at a slower, more manageable pace. Revterra's battery acts as an intermediary to store that energy until the consumer is ready to charge.

"It's an energy accumulator and a high-power energy discharger," Jawdat says, explaining that compared to an electrical chemical battery, which could be used to store energy for EVs, kinetic energy can be used more frequently and for faster charging.

Jawdat, who is a trained physicist with a PhD from the University of Houston and worked as a researcher at Rice University, says some of his challenges were receiving early funding and identifying customers willing to deploy his technology.

Last year, Revterra raised $8.5 million in a series A funding round. Norway’s Equinor Ventures led the round, with participation from Houston-based SCF Ventures and At One Ventures. Previously, Revterra raised nearly $500,000 through a combination of angel investments and a National Science Foundation grant.

The funding has gone toward growing Revterra's team, including onboarding three new engineers with some jobs still open, Jawdat says. Additionally, Revterra is building out its new lab space and launching new pilot programs.

Ultimately, Revterra, an inaugural member of Greentown Houston, hopes to be a major player within the energy transition.

"We really want to be an enabling technology in the renewable energy transition," Jawdat says. "One part of that is facilitating the development of large-scale, high-power, fast-charging networks. But, beyond that, we see this technology as a potential solution in other areas related to the clean energy transition."

Houston EV charging tech company raises $6M series A

money moves

Houston-based tech company Revterra Corp. has picked up $6 million in a series A funding round to propel development of its battery for electric vehicle charging stations.

Norway’s Equinor Ventures led the round, with participation from Houston-based SCF Ventures. Previously, Revterra raised nearly $500,000 through a combination of angel investments and a National Science Foundation grant.

Revterra says its kinetic flywheel battery enables quick, simple, cost-effective installation of high-powered DC chargers for electric vehicles. The technology eases the burden placed on electrical grids, the company says.

“There is an urgent need to reduce carbon emissions globally,” physicist Ben Jawdat, founder and CEO of Revterra, says in a news release. “Our goal at Revterra is to deploy scalable energy storage solutions that facilitate the shift to renewables and EVs while hardening our electric grid. Our systems enable these ambitions while utilizing materials that are recyclable and based on a secure supply chain.”

Jawdat earned a doctoral degree from the University of Houston, and he completed postdoctoral studies at Rice University and the Air Force Research Laboratory.

Revterra says its battery lasts eight times longer than traditional chemical batteries for EV charging do, supplies four times the power output, and causes less of an environmental impact.

“Revterra’s differentiated energy storage systems will be key to enabling fast charging capabilities for EVs and improving the resiliency of the power grid,” says Hossam Elbadawy, managing director of SCF Ventures. “A successful energy transition needs effective energy storage, and innovative technologies like Revterra’s flywheel will provide an important part of the answer.”

In 2021, Revterra joined Greentown Labs in Houston. The five-year-old startup says it plans to expand its workforce over the next 12 months, filling positions in areas such as electrical, mechanical, and manufacturing engineering. Some of those employees will be involved in building Revterra’s first assembly facility, which will be located in Houston.

Revterra plans to roll out its first full-size, commercial-ready batteries in 2023. The batteries are being designed to let an EV driver recharge a car’s battery in 15 minutes or less without taxing the existing electrical grid.

7 lessons from a Houston-based unicorn startup founder

taking notes

At a fireside chat at SXSW, a Houston founder pulled back the curtain on his entrepreneurial journey that's taken him from an idea of how to make the chemicals industry more sustainable to a company valued at over $2 billion.

Gaurab Chakrabarti, the CEO and co-founder of Solugen, joined the Greater Houston Partnership's Houston House at SXSW on Monday, March 13, for a discussion entitled, "Building a Tech Unicorn." In the conversation with Payal Patel, principal of Softeq Ventures, he share the trials and tribulations from the early days of founding Solugen. The company, which has raised over $600 million since its founding in 2016, has an innovative and carbon negative process of creating plant-derived substitutes for petroleum-based products.

The event, which quickly reached capacity with eager SXSW attendees, allowed Chakrabarti to instill advice on several topics — from early customer acquisition and navigating VC investing to finding the right city to grow in and setting up a strong company culture.

Here are seven pieces of startup advice from Chakrabarti's talk.

1. Don’t be near a black hole.

Chakrabarti began his discussion addressing the good luck he's had standing up Solugen. He's the first to admit that luck is an important element to his success, but he says, as a founder, you can set yourself up for luck in a handful of ways.

“You do make your own luck, but you have to be putting in the work to do it," Chakrabarti says, adding that it's not an easy thing to accomplish. “There are things you can be doing to increase your luck surface area."

One of the principals he notes on is not surrounding yourself with black holes. These are people who don't believe in your idea, or your ability to succeed, Chakrabarti explains, referencing a former dean who said he was wasting his talent on his idea for Solugen.

2. The co-founder dynamic is the most important thing.

Early on, Chakrabarti emphasizes how important having a strong co-founder relationship is, crediting Solugen's co-founder and CTO Sean Hunt for being his "intellectual ping-pong partner."

“If you have a co-founder, that is the thing that’s going to make or break your company,” he says. “It’s not your idea, and it’s not your execution — it’s your relationship with your co-founder.”

Hunt and Chakrabarti have been friends for 12 years, Chakrabarti says, and, that foundation and the fact that they've been passionate about their product since day one, has been integral for Solugen's success.

"We had a conviction that we were building something that could be impactful to the rest of the world," he says.

3. Confirm a market of customers early on.

Chakrabarti says that in the early days of starting his company, he didn't have a concept of startup accelerators or other ways to access funding — he just knew he had to get customers to create revenue as soon as possible.

He learned about the growing float spa industry, and how a huge cost for these businesses was peroxide that was used to sanitize the water in the floating pods. Chakrabarti and Hunt had created a small amount of what they were calling bioperoxide that they could sell at a cheaper cost to these spas and still pocket a profit.

“We ended up owning 80 percent of the float spa market,” Chakrabarti says. “That taught us that, ‘wow, there’s something here.”

While it was unglamourous work to call down Texas float spas, his efforts secured Solugen's first 100 or so customers and identified a path to profitability early on.

“Find your niche market that allows you to justify that your technology or product that has a customer basis,” Chakrabarti says on the lesson he learned through this process.

4. Find city-company fit.

While Chakrabarti has lived in Houston most of his life, the reason Solugen is headquartered in Houston is not due to loyalty of his hometown.

In fact, Chakrabarti shared a story of how a potential seed investor asked Chakrabarti and Hunt to move their company to the Bay Area, and the co-founders refused the offer and the investment.

“There’s no way our business could succeed in the Bay Area," Chakrabarti says. He and Hunt firmly believed this at the time — and still do.

“For our business, if you look at the density of chemical engineers, the density of our potential customers, and the density of people who know how to do enzyme engineering, Houston happened to be that perfect trifecta for us," he explains.

He argues that every company — software, hardware, etc. — has an opportunity to find their ideal city-company fit, something that's important to its success.

5. Prove your ability to execute.

When asked about pivots, Chakrabarti told a little-known story of how Solugen started a commercial cleaning brand. The product line was called Ode to Clean, and it was marketed as eco-friendly peroxide wipes. At the time, Solugen was just three employees, and the scrappy team was fulfilling orders and figuring out consumer marketing for the first time.

He says his network was laughing at the idea of Chakrabarti creating this direct-to-consumer cleaning product, and it was funny to him too, but the sales told another story.

At launch, they sold out $1 million of inventory in one week. But that wasn't it.

“Within three months, we got three acquisition offers," Chakrabarti says.

The move led to a brand acquisition of the product line, with the acquirer being the nation's largest cleaning wipe provider. It meant three years of predictable revenue that de-risked the business for new investors — which were now knocking on Solugen's door with their own investment term sheets.

“It told the market more about us as a company,” he says. “It taught the market that Solugen is a company that is going to survive no matter what. … And we’re a team that can execute.”

What started as a silly idea led to Solugen being one step closer to accomplishing its long-term goals.

“That pivot was one of the most important pivots in the company’s history that accelerated our company’s trajectory by four or five years," Chakrabarti says.

6. Adopt and maintain a miso-management style.

There's one lesson Chakrabarti says he learned the hard way, and that was how to manage his company's growing team. He shares that he "let go of the reins a bit" at the company's $400-$500 million point. He says that, while there's this idea that successful business leaders can hire the best talent that allows them to step back from the day-to-day responsibilities, that was not the right move for him.

“Only founders really understand the pain points of the business," Chakrabarti says. "Because it’s emotionally tied to you, you actually feel it."

Rather than a micro or macro-management style, Chakrabarti's describes his leadership as meso-management — something in between.

The only difference, Chakrabarti says, is how he manages his board. For that group, he micromanages to ensure that they are doing what's best for his vision for Solugen.

7. Your culture should be polarizing.

Chakrabarti wrapped up his story on talking about hiring and setting up a company culture for Solugen. The company's atmosphere is not for everyone, he explains.

“If you’re not polarizing some people, it’s not a culture,” Chakrabarti says, encouraging founders to create a culture that's not one size fits all.

He says he was attracted to early employees who got mad at the same things he did — that passion is what makes his team different from others.

3 Houston innovators to know this week

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from space tech to software development — recently making headlines in Houston innovation.

In terms of Houston developing as an attractive hub for biotech companies, Julie King says the city still has one major obstacle: Available lab space.

She writes in a guest column for InnovationMap that biotech startups need specialized space that can hold the right equipment. That's not cheap, and it's usually a challenge for newer companies to incur that cost.

"However, with realistic expectations about these challenges, the good news is that once settled into a facility that is a fit, Houston’s emerging biotech companies can thrive and grow," she writes. Read more.

Owen Goode is a huge fan of Houston. That's why when his software design firm, Axon, got acquired by Zaelot, led by CEO Jeff Lombard, in January, he made sure the deal would mean growth in the region.

Zaelot is a global, software firm with a presence in 14 countries, mostly focused in the United States, Uruguay, and Iceland. With the acquisition of Axon, the combined company is poised to expand in Texas, beginning in Houston, Goode says.

“Together we have a strong suite of offerings across a wide variety of domains including full-stack development, cloud/data engineering, design, staff augmentation, project management, and software architecture. We also have experience in multiple domains, including health care, aviation, defense, finance, and startups,” says Goode. Read more.

Following Silicon Valley Bank collapse, banking diversification is key for Houston founders

SVB shake up

Last week, Houston founder Emily Cisek was in between meetings with customers and potential investors in Austin while she was in town for SXSW. She was aware of the uncertainty with Silicon Valley Bank, but the significance of what was happening didn't hit her until she got into an Uber on Friday only to find that her payment was declined.

“Being positive in nature as I am, and with the close relationship that I have with SVB and how they’ve truly been a partner, I just thought, ‘OK, they’re going to figure it out. I trust in them,'” Cisek says.

Like many startup founders, Cisek, the CEO of The Postage, a Houston-based tech platform that enables digital legacy planning tools, is a Silicon Valley Bank customer. Within a few hours, she rallied her board and team to figure out what they needed to do, including making plans for payroll. She juggled all this while attending her meetings and SXSW events — which, coincidentally, were mostly related to the banking and fintech industries.

Sandy Guitar had a similar weekend of uncertainty. As managing director of HX Venture Fund, a fund of funds that deploys capital to venture capital firms around the country and connects them to the Houston innovation ecosystem, her first concern was to evaluate the effect on HXVF's network. In this case, that meant the fund's limited partners, its portfolio of venture firms, and, by extension, the firms' portfolios of startup companies.

“We ultimately had no financial impact on venture fund 1 or 2 or on any of our portfolio funds or our underlying companies,” Guitar tells InnovationMap. “But that is thanks to the Sunday night decision to ensure all deposits.”

On Sunday afternoon, the Federal Deposit Insurance Corp. took control of SVB and announced that all accounts would be fully insured, not just up to the $250,000 cap. Customers like Cisek had access to their accounts on Monday.

“In the shorter term, the great news is SVB entity seems to be largely up and functioning in a business as usual manner,” Guitar says. “And they have a new leadership team, but their existing systems and predominantly the existing employee base is working well. And what we're hearing is that business as usual is taking place.”

Time to diversify

In light of the ordeal, Guitar says Houston founders and funders can take away a key lesson learned: The importance of bank diversification.

“We didn't think we needed one last week, but this week we know we need a resilience plan," she says, explaining that bank diversification is going to be added to "the operational due diligence playbook."

"We need to encourage our portfolio funds to maintain at least two banking relationships and make sure they're diversifying their cash exposure," she says.

A valued entity

Guitar says SVB is an integral part of the innovation ecosystem, and she believes it will continue on to be, but factoring in the importance of resilience and diversification.

"Silicon Valley Bank and the function that they have historically provided is is vital to the venture ecosystem," she says. "We do have confidence that either SVB, as it is currently structured or in a new structure to come, will continue to provide this kind of function for founders."

Cisek, who hasn't moved any of her company's money out of SVB, has similar sentiments about the importance of the bank for startups. She says she's grateful to the local Houston and Austin teams for opening doors, making connections, and taking chances for her that other banks don't do.

"I credit them to really being partners with startups — down to the relationships they connect you with," she says. "Some of my best friends who are founders came from introductions from SVB. I've seen them take risks that other banks won't do."

With plans to raise funding this yea, Cisek says she's already started her research on how to diversify her banking situation and is looking into programs that will help her do that.

Staying aware

Guitar's last piece of advice is to remain confident in the system, while staying tuned into what's happening across the spectrum.

“This situation that is central to the venture ecosystem is an evolving one," she says. "We all need to keep calm and confident in business as usual in the short term while keeping an eye to the medium term so that we know what happens next with this important bank and with other associated banks in the in our industry."
