The 20 AI companies shown here span rounds from May 2021 through August 2025, all headquartered in Houston, Texas. The largest disclosed raise is OpenStax's $90M round in April 2024, an outlier in a dataset where most disclosed amounts fall well below $30M. Other notable raises include Imubit's $30M Series B (August 2021) and Draup's $20M Series A (March 2022). Recent activity includes Lena Health's $2M Seed round in April 2025, Amperon's undisclosed raise in July 2025, and Ainnova Tech's Series A in August 2025—reflecting continued deal flow in health and energy AI, two verticals with deep roots in the Houston market.
Round classification varies across the set: six entries are labeled Series Unknown, four are Seed, four are Series A, two are grants, two are Pre-Seed, and one is Series B. A substantial share of rounds carry undisclosed amounts, appearing at early stages (IMPAVIDUS, Cognitive Space) and at Series A (LTV.ai) alike. The range from pre-seed to Series B means this segment presents prospecting opportunities across multiple pipeline stages.

Frequently asked
What are the largest disclosed rounds among these 20 companies?
OpenStax leads at $90M (April 2024), followed by Imubit at $30M (Series B, August 2021) and Draup at $20M (Series A, March 2022). Bees360 reported $10M and Rugged Robotics raised $9M in a Series A closed the same week as Draup in March 2022.
Which companies closed rounds most recently?
Ainnova Tech closed a Series A on August 8, 2025, and Amperon reported a raise (amount undisclosed) on July 16, 2025. Lena Health preceded both with a $2M Seed round in April 2025.
How many rounds in this set carry undisclosed amounts?
At least eight of the 20 rounds list no dollar figure, including LTV.ai (Series A, January 2025), Amperon (July 2025), IMPAVIDUS, Cognitive Space, and nVenue. Undisclosed amounts appear at both early and later stages across the dataset.
What sectors do these Houston AI startups cluster around?
The data shows concentration in energy and utilities (Amperon, Imubit), healthcare (Lena Health, MobilityZ Health, Melax Technologies), industrial operations (Industrial Data Labs, Rugged Robotics), and edtech (OpenStax, ThirdAI). This maps closely to Houston's established strengths in the energy corridor and the Texas Medical Center.
Are any companies in this group grant-funded rather than equity-backed?
Two are: Melax Technologies received a $300K grant in August 2022 and Pandata Tech received a $100K grant in May 2022. Both are Houston-based and likely drew from government or institutional research programs rather than venture capital.
What round stages are most represented in this set?
Series Unknown accounts for six of the 20 entries, the single largest classification. Seed and Series A rounds each appear four times. Series B shows up once—Imubit's $30M raise in August 2021—making growth-stage deals the exception rather than the rule in this group.
