seed funding

A Houston company that's providing innovative unified scheduling software for the logistics industries has raised additional seed funding.

Houston-based Velostics Inc. raised $1.95 million, the company announced this week. The additional seed round follows a $2.5 million round announced in 2021. The Velostics platform optimizes scheduling for inbound and outbound trucks, saving companies money across the supply chain and resulting in fewer emissions from idling trucks.

“Scheduling is a major headache for all parties focused on reducing cost and delivering on high customer expectations — our cloud based solution is designed to go live in one day with no apps required,” Gaurav Khandelwal, founder and CEO of Velostics, says in a news release.

Houston-based Starboard Star Venture Capital led the round, and Flyover Capital and Small Ventures USA, both previous investors in Velostics, contributed too. Additionally, Mexico-based Capital Mazapil joined in as a new investor. The family office has close ties to a leading CPG company with a global footprint of manufacturing plants and distribution warehouses, per the news release.

“At a time where all costs are increasing, Velostics has a proven solution that brings real cost savings and more importantly, increased capacity to manufacturing facilities, warehouses and fuel terminals," Keith Molzer, founding partner at Flyover Capital, says in the news release.

Khandewal founded Velostics in 2019 after seeing the business opportunity through ChaiOne, a Houston software company he's run since 2009. In an episode of the Houston Innovators Podcast, he shared the story of Velostics and why he thinks the city has a great opportunity to be a leader in logistics technology.

3 Houston innovators to know this week

WHO'S WHO

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

Gaurav Khandelwal, CEO and founder of Velostics

The logistics industry has a lot of room for improved optimization — and that's exactly what Gaurav Khandelwal set out to do when he founded Velostics. The company just raised its $2.5 million seed round that will go toward recruiting top talent for Velostics's team, particularly in its account management, inside sales, and marketing departments, as well as continuing to develop the AI-driven product, which has an impact for both its users and the environment.

“Idling trucks waiting outside facilities emit over 42 million tons of CO2 annually — eight times the US national average. By orchestrating the movement of trucks in and out of facilities, not only do we provide tremendous supply chain benefits, we also help the environment," Khandelwal says in the release. "We’re excited to partner with our customers and our investors to solve global congestion.” Click here to read more.

Samantha Hepler, CEO and founder of SeekerPitch

When Houstonian Samantha Hepler was trying to find a job, she couldn't even get in the door. Due to algorithms and antiquated hiring processes, she was overlooked.

"I knew if I could just get through the door, a company would see the value in me," Hepler tells InnovationMap. "I wasn't being seen, and I wasn't being heard. I didn't know a way to do that."

This experience gave her the idea for SeekerPitch, a platform that allows job seekers to create an account and tell their story — not just their job history. The platform prioritizes video content and quick interviews so that potential hires can get face-to-face with hiring managers. Click here to read more.

Zain Shauk, co-founder and CEO of Dream Harvest

Houston-based Dream Harvest Farming Co., which specializes in sustainably growing produce, has landed a $50 million investment from Orion Energy Partners to open a 100,000-square-foot indoor farming facility in Houston. The facility will enable the company to dramatically ramp up its operations.

Zain Shauk, co-founder and CEO of Dream Harvest, says his company’s method for growing lettuce, baby greens, kale, mustards, herbs, collards, and cabbage helps cut down on food waste.

“Demand for our produce has far outpaced supply, an encouraging validation of our approach as well as positive news for our planet, which is facing the rising problem of food and resource waste,” Shauk says. “While we have the yields today to support our business, we are pleased to partner with Orion on this financing, which will enable us to greatly expand our production and increase access to our produce for many more consumers.” Click here to read more.

Exclusive: Houston logistics SaaS startup raises $2.5M seed round

money moves

A Houston company that's providing software solutions for middle-mile logistics challenges has raised fresh funding.

Velostics Inc., which has an enterprise software-as-a-service model that specializes in automating inbound logistics at industrial facilities — like terminals and warehouses — announced it has raised $2.5 million. The seed round was led by Kansas-based Flyover Capital with participation from Small Ventures USA, Cultivation Capital, Starboard Star, Congress Avenue Ventures and BioUrja Ventures.

Founded by Gaurav Khandewal, Velostics targets the $37 billion inbound logistics management market, a so-called "log jam" for businesses that the company's software strives to make flow a lot more optimally.

“Flyover is incredibly excited to support the Velostics team in their mission to transform inbound logistics,” says Keith Molzer, managing partner at Flyover Capital. “This segment of the supply chain is ripe for better technology to address challenges of congestion, driver labor shortages, and the growing demands of ecommerce. Gaurav and team are an exceptional group of entrepreneurs ready to drive efficiency and a better customer experience at industrial facilities.”

The fresh funding will go toward recruiting top talent for Velostics's team, particularly in its account management, inside sales, and marketing departments, as well as continuing to develop the AI-driven product, which has an impact for both its users and the environment.

“Idling trucks waiting outside facilities emit over 42 million tons of CO2 annually — eight times the US national average. By orchestrating the movement of trucks in and out of facilities, not only do we provide tremendous supply chain benefits, we also help the environment," Khandewal says in the release. "We’re excited to partner with our customers and our investors to solve global congestion.”

Flyover Capital was founded in 2014 and has a keen interest in the Houston market, Dan Kerr, principal at the firm, previously told InnovationMap.

Houston is "one of the cities among those that fall in our region where we plan to spend a significant amount of time," Kerr said in May of last year. "We cover a lot of ground, but there are certain cities were we try to get there quarterly. Houston is definitely one of those places."

In September, Khandewal joined the Houston Innovators Podcast and discussed how he has been a champion of Houston innovation since he started ChaiOne in 2009. He shared how he thinks the city has a great opportunity to be a leader in logistics technology.

"I think that there are some trends in Houston that I'm seeing as a founder, and one of them is logistics," Khandewal says on the show.

3 Houston innovators to know this week

who's who

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

Amanda Edwards, former Houston City Council Member

A couple years ago, Houston City Council Member Amanda K. Edwards, along with entrepreneurs Carolyn Rodz and Courtney Johnson Rose, formed a task force to provide Mayor Sylvester Turner with recommendations about increasing increase access to capital for minority- and women-owned business enterprises and assisting these business owners in scaling up their businesses. The task force created the Houston Small Business Community Report, which shed light on the disparities in access to resources for women and BIPOC-founders.

In response to this report, Edwards and a cohort of female leaders have launched the Business Ecosystem Alliance for Minorities and Women, or BEAMW, to address these disparities these businesses face when seeking capital and attempting to scale their businesses.

"It is not enough to state that Houston is the most diverse city in the country; we must be the city where the challenges that diverse communities face are solved," Edwards says in a release. Click here to read more.

Gaurav Khandelwal has been an advocate for growing Houston's innovation ecosystem since he started his company ChaiOne — an industrial software provider — in 2008. Now, with his new company, Velostics, he is passionate about making Houston a hub for logistics innovation too.

"I think that there are some trends in Houston that I'm seeing as a founder, and one of them is logistics," Khandewal says on this week's episode of the Houston Innovators Podcast.

"If you look at Chicago — it's had some crazy amount of logistics unicorns that have popped up over the past few years, and they aren't slowing down," Khandewal says on the show. "Houston, I would argue, is better positioned, because we have this massive port. I think logistics is a massive opportunity for Houston." Click here to read more and listen to the episode.

A seed-stage company is changing the game for data science and artificial intelligence, and the technology was developed right on the Rice University campus.

ThirdAI, founded by Anshumali Shrivastava in April, raised $6 million in a seed funding round from three California-based VCs — Neotribe Ventures and Cervin Ventures, which co-led the round with support from Firebolt Ventures.

"We are democratizing artificial intelligence through software innovations," says Shrivastava in a news release from Rice. "Our innovation would not only benefit current AI training by shifting to lower-cost CPUs, but it should also allow the 'unlocking' of AI training workloads on GPUs that were not previously feasible."

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
