Editor's note: CultureMap Austin editor Brianna Caleri recently attended a dinner arranged by Timeleft, an app that helps people meet each other. The app just launched in Houston — read about Brianna's experience using the app below.

Conventional wisdom — if I may be so bold as to define it — would suggest that people who want to make friends should: select a genuine interest, join a group centered around it, and keep attending meetings. I have not quite been sold on the generic women's group meetups I see on Facebook; and even the most passionate conversations about my ramen bar neighbor's favorite noodle dishes at have never led us to hang out a second time.

I tend to look for friends who will suggest ethical shopping alternatives, make impassioned, over-intellectualized art recommendations, and stay up late workshopping existential dread. But I recognize that's a lot to ask after one dinner.

Thus, I was both surprised and not surprised at all to really enjoy Austin's second-ever Timeleft dinner, a lightly match-made night out for strangers. I don't think I've discovered a new portal to jump into and skip all the awkward early stages of making adult friends, but I had an energizing night with people who impressed me with their social ease and willingness.

The setup
When someone signs up for the French app Timeleft, they are greeted with a pleasantly detailed, yet broad personality test. First, a this-or-that rapid fire: things like, "Do you consider yourself more of a smart person or funny person?" (Smart.) "Would you rather listen to rock or rap?" (Rock.) "Are your opinions usually guided by logic and facts, or emotions and feelings?" (Tough, but I chose logic.) Next is a 1-10 rating scale in areas like intro/extroversion, stress, spirituality, loneliness, creativity, and habits.

Some of these, like "I enjoy going out with friends" and "How important is family to you?", felt neat and inspired concise answers. Others, like "I enjoy politically incorrect humor" and "I enjoy discussing politics/news," felt like minefields. I do enjoy a wicked joke, but are we talking politically incorrect like The Office, or politically incorrect like I got kicked out of my bookclub and believe no one can take a joke anymore? I selected 3 for political incorrectness, and 8 for discussing news and politics, angling hard toward sensitivity and away from potential, if unlikely belligerence.

According to Timeleft, its algorithm considers these answers and a few other logistics to pair users with a restaurant and with each other, resulting in two medium-size tables at each. Our group of seven met at 68 Degrees Kitchen in East Austin; It would have been eight, but one didn't show up. A Timeleft representative says the app overbooked from the intended five, expecting that some people would not show.

Quoted from Timeleft's algorithm explanation, it focuses on these "main ingredients":

  • "Language: Select yours for fluid dialogue[...]"
  • "Balance: A balanced mix of men and women. Note that Timeleft is favored by women, who often make up over 60 percent of participants (thus 4 per table). [Note: Although Timeleft only mentions men and women on this list, it also offered a nonbinary gender marker)"
  • "Temperament: A mix of introverts and extroverts for a balanced rhythm."
  • "Generation: An age gap of five to seven years for common life echoes."

Before we met, we got to see a basic rundown of who would be joining, detailing profession, nationality, and zodiac signs. (Not my ideal trifecta, considering that six-sevenths of us were American, and I'm fairly confident in my ability to interact with people born on any day.) I don't think it's incredibly open-minded of me, but I did feel slightly nervous that half the group worked in tech; I like tech workers, but can't say I really relate.

The dinner
An unexpected point of beauty in the often overwrought world of app-coordinated socializing: Beyond matching us and making our reservation, Timeleft left us to a normal dinner. We ordered from the regular menu, sat among the regular clientele, and handled the payment ourselves, opting to get in a group chat and Venmo one person for one clean bill. It offered a "game," which was really just a list of conversation topics; We only got through two before the topic changing ran cheerfully rampant.

A group of seven — although it did increase the likelihood that we would all like at least one of our companions — was perhaps a bit too large to get to know anyone especially well. We talked as a large group about as much as we split into side conversations. That was perfectly doable, but it made me wish a few times that we had a quiet table of three or four, where we didn't have to raise our voices past each other or inelegantly shift our attention from one conversation to the next.

We discovered a fair amount in common: places lived, schools attended, foods loved, places traveled, parties and underground scenes frequented. Although some of it dipped very lightly into taboos (Who has been to sex clubs? Who has been kicked out of restaurants?), most of these were surface-level parallels.

I learned that one of my dinner mates shared my lack of enthusiasm for school spirit as a concept, but couldn't say whether it was simply noncommittal or deep-rooted antiestablishmentarianism. I learned that at least one of my dinner mates likes to do yoga, but I don't know if they prefer to work up a sweat to EDM or study the Yoga Sutras.

It would be hard to suss out many of the deeper values behind these things, since seven people sitting at a dinner table together are generally trying to be agreeable — or at least entertaining. We're playing to the lowest common denominator, and we don't really know what our denominators are. We never found the gold thread running through — for instance, if we all rated our passion for working out similarly. But if we could narrow it down that much, it might be time to cut out the middle man and join a CrossFit gym.

The after-dinner drinks, and social patterns
After the small group dinners, all the diners from the various Timeleft tables in South and Central Austin were invited to meet up at Hold Out Brewing. Our group (less one person with a morning appointment) decided to head over. It was already 9:45 pm by the time we left the restaurant, having spent nearly 3 hours together already. We were surprised to see the dense crowd that gathered among the picnic tables.

In reporter mode, I started popping by different groups to find out how their night had gone. I talked to more than a dozen people, all of whom had entirely positive feedback about their evenings. The only criticism I heard was that one person felt the $16 "ticket" to the dinner (which was then priced à la carte) was a bit pricy.

Other groups went to Fresa's Chicken al Carbon, North Italia, and what I have to assume was QI Austin: Modern Asian Kitchen, although diners kept pronouncing it "key." Most groups had met members of the other table at the same restaurant, and some even wandered over during the dinner to see how the other half lived. Our group never found its counterpart.

It seemed to me that our group was objectively the most outgoing. Not only were we the last to arrive after our long dinner (as far as I noticed), but we were also (definitely) the last to leave the brewery. One duo from another group said theirs was a little awkward, in a pleasant way, so the two of them kept up most of the talking. One group said conversation flowed fairly easily, but when there was a lull, they returned to the provided conversation topics. It seemed about equally common to share meals or order for yourself, but our gang all shared everything.

Every group noticed their close ages beyond any other unifying factor. No one offered up any common threads, yet people responded in conversation as if they knew each other, with affectionate interjections like, "Of course he would say that!"

Final impression
Most interesting to me was that nearly every single person I talked to all night, including in our own group, first heard about the dinner series on Instagram and just thought it sounded worth trying. Only one person specifically told me that they wanted to make new friends because theirs were mostly from work.

My biggest prejudice before the dinner was that the majority of attendees would either be new to Austin or in need of some outside help in making friends. I was right about the first thing; It seemed like most people had only been here a year or less.

But I was wrong about the second thing. In retrospect, it makes sense that a huge group of people who got together just to get together are deeply friendly. And while I still wouldn't expect long-lasting connections to come out of this Friendly People Convention, I can see that's not exactly what most people are aiming for, either.

The app has direct messaging, but I don't feel inclined to use it. Our group is already on an SMS thread, and I got so many new Instagram followers at the after-event that the next morning, I was not even sure who one of them was. We have started rating our compatibility on the app, and indicating who we would be open to seeing at future events, and who we wouldn't.

If I can have a silly dinner with someone who is investing in the world I want to see, I'll happily get silly. I'm sure some of the people I met yesterday are doing that, but I would have little way of knowing — or at least, a much harder time than if we had started on shared ground.

It's tempting, then, to see this as a way to meet people who are very different from you and expand your worldview. I do think it holds some promise for people who want to legitimately invest in becoming friends with each other and learning what's underneath the amiable surface, but I'm curious about where that sense of initiative will come from. Perhaps more regular dinners hold the answer.

I would be happy to see anyone I met yesterday again, if we end up in the same place at the same time. But I think my days of connecting with strangers over no common objective at all are limited.

Houston healthtech startup raises $30M to scale surgical healing gel

fresh funding

Houston-based healthtech startup TYBR Health has raised a $30 million Series A round to scale its B3 GEL System, which helps protect tendons from scarring after surgery.

The round was led by Minneapolis-based Vensana Capital and Cleveland-based Mutual Capital Partners, with participation from Denver-based Neovate Capital Partners and existing investors, according to a news release from the company.

TYBR Health said it plans to use the funding to broaden the B3 GEL System's clinical applications, expand commercialization and conduct studies to evaluate its ability to protect tissue and improve healing outcomes.

"Surgeons are exceptionally good at the structural repair, but the biology that follows is what determines how it heals. That part of the equation has gone largely unaddressed ... There's a shift underway across surgical specialties, from focusing almost entirely on the mechanical repair to also weighing the biological conditions that repair needs to succeed," Tim Keane, co-founder and CEO of TYBR Health, said in the news release. "This financing lets us reach more surgeons and generate the clinical evidence to move that shift forward."

As part of the financing round, Greg Banker of Vensana Capital and Liz Todia Zambory of Mutual Capital Partners will join the TYBR board, alongside independent director Aaron Smith.

"TYBR Health is addressing a gap surgeons have lived with for a long time, with a product that fits the way they already work," Zambory, principal at Mutual Capital Partners, added in the release. "We're excited to co-lead this round and support the company's growth."

TYBR was founded in 2020 and originated from the TMCi’s Biodesign fellowship and participated in the TMC's Accelerator for HealthTech. Its B3 GEL System is a flowable extracellular matrix hydrogel designed to protect tendons, ligaments, muscles, and the surrounding soft tissue while they heal from orthopedic surgery. It received FDA 510(k) clearance last June and launched an Australian clinical trial in the fall.

The B3 GEL System has been used in hand, wrist, shoulder, foot and ankle, and sports medicine procedures since it launched, according to the company, and was first used in the clinical setting earlier this year by Dr. Tammam Hanna with Texas Tech University Health Sciences Center.

Houston space companies win NASA funding to build Mars exploration robots

mission to mars

Two Houston-area spacetech companies have landed a portion of a $17 million award from NASA to develop robots for exploring the surface of Mars, the agency announced this month.

Houston-based Inuitive Machines and Webster, Texas-based MEI Technologies, which does business as Aegis Aerospace, were among the seven companies selected to receive the funding from NASA's Science Transport and Robotic Innovation for Deployment and Exploration (STRIDE) initiative.

According to the release from NASA, the companies are tasked with creating "innovative mobility systems" that would allow future Mars missions to access more challenging terrain and difficult-to-reach regions of the planet, and to travel farther distances. NASA estimated that the work will begin this fall.

NASA solicited proposals for participants in the STRIDE initiative in January. The seven named companies are the first selected to participate in the program.

The additional five companies to receive STRIDE funding include:

"STRIDE demonstrates NASA’s commitment to strong public-private partnerships, allowing the agency to explore new approaches for Mars surface exploration while identifying key capability gaps and development needs for commercial systems that could operate and traverse realistic Martian environments," NASA shared in the announcement.

Last month, Intuitive Machines was awarded $148.3 million to deliver its Nova-C lander to the moon. The funding was part of $600 million the space agency awarded to three companies as part of its Moon Base Program and was Intuitive Machines' sixth task order under NASA's Commercial Lunar Payload Services (CLPS) program. Astrobotic was also one of the companies to land funding for the Moon Base program, as well as Austin-based Firefly Aerospace.

Around the same time, Firefly Aerospace was awarded a $13 million subcontract from NASA’s Jet Propulsion Laboratory to develop technology for NASA’s SkyFall mission to Mars. The mission aims to deploy three Mars helicopters to "perform science and demonstrate airborne subsurface mapping and resource prospecting on the planet." Read more here.
