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.

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.

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

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."

UH scores $18M NIH grant for chronic disease research

research funding

The University of Houston has received a coveted $18.8 million grant from the National Institutes of Health to launch a program to address the root causes of chronic disease.

Only 22 institutions nationwide receive this NIH award, and the 5-year process aligns with the newly established UH Health’s mission to expand healthcare innovations in Texas and beyond. The initiative will be housed in the UH Population Health department.

"This generous funding allows us to directly confront the root causes of chronic illness that place a heavy burden on so many families," Dr. Jonathan McCullers, vice president for health affairs at UH, said in a news release. "With the recent launch of UH Health, we have an unprecedented opportunity to translate scientific discovery into healthier outcomes for our communities by bringing together experts from across the university to improve health where it matters most.”

Through the program, UH researchers from different areas of expertise will work together to address the challenges of chronic illness by looking at biological, social and behavioral factors.

According to the university, chronic diseases like heart disease, diabetes, strokes and others are the leading cause of illness, disability and death in the U.S. They account for 90 percent of the nation’s $5.3 trillion in annual healthcare spending.

Bettina Beech, chief of population health and translational science at UH, serves as principal investigator for the program.

“Chronic disease management largely happens during the 8,700 hours each year that people are not visiting their healthcare provider,” Beech added in the news release. “While healthcare is indispensable, it only accounts for 20 percent of how health is created — genetics accounts for another 10 percent, and the other 70 percent is determined by behavior, social conditions and environment.”

With the funds from the grant, UH will also be able to expand research infrastructure, add to community partnerships, support complementary research, and invest in early-career investigators, according to the news release. UH also aims to develop solutions that could help ease the economic burden of chronic disease.

Report: Where Texas ranks among best and worst states to live in 2026

Texas Talk

After earning its worst-ever ranking last year, Texas has improved slightly on an evaluation of the best states to live, but it's still at the bottom of the pack.

Each year, WalletHub's analysts compare all 50 states using 51 livability metrics to measure their affordability, economy, education and health, quality of life, and safety. Factors that were weighed include the cost of living, homeownership rates, population and income growth rates, wealth gaps, public school system quality, road quality, crime rates, and many others.

The Lone Star State landed at No. 36 in 2026, making it the 15th worth state to live right now. That's on par with its 2024 ranking, and it's a two-spot improvement over its 2025 performance.

While Texas residents can brag about living in a state with the No. 1 highest number of restaurants per capita and the 7th best quality of life in the country, that's about it. Texas earned middling-to-poor scores among the four remaining livability rankings: safety (No. 33), affordability (No. 35), economy (No. 37), and education and health (No. 40).

Here's how Texas fared in other nationwide rankings in the study:

  • No. 27 – Income Growth
  • No. 30 – Housing Costs
  • No. 39 – Percentage of Population in Poverty
  • No. 42 – Percentage of Adults in Fair or Poor Health
  • No. 46 – Homeownership Rate
  • No. 49 – Percentage of Population Aged 25 and Older with a High School Diploma or Higher
  • No. 48 – Average Weekly Work Hours
  • No. 50 – Percentage of Insured Population

Texas has a lot of work to do to improve its livability for all of its residents, but especially for women, according to several other 2026 WalletHub studies. Texas is the fourth-worst state for women, the ninth-worst state for working mothers, and the seventh-worst place to have a baby based on limited access to maternal and pediatric healthcare.

At the very bottom of the report is New Mexico, ranking 50th overall, with Louisiana (No. 49), Mississippi (No. 48), Alaska (No. 47), and Arkansas (No. 46) rounding out the bottom five.

After holding on as the No. 1 best state to live for a few years in a row, Massachusetts now ranks No. 4 and was overtaken by Idaho (No. 1), New Jersey (No. 2), and Wisconsin (No. 3). New Hampshire rounds out the top five best states to live.

WalletHub's top 10 best states to live in 2026 are:

  • No. 1 – Idaho
  • No. 2 – New Jersey
  • No. 3 – Wisconsin
  • No. 4 – Massachusetts
  • No. 5 – New Hampshire
  • No. 6 – Wyoming
  • No. 7 – Utah
  • No. 8 – Minnesota
  • No. 9 – Pennsylvania
  • No. 10 – Florida
