Before Dina Turner raised millions of dollars, there were 140 characters. That was the entry limit for a technology competition whose finalists would pitch at Founders Forum in 2015. Turner, then a 20-year-old University College London student named Dina Radenkovic, entered an idea for an app. She became one of the runners-up. A student with a scientific education had found a room full of people who made businesses out of ideas. It was an education with rather different homework.
The event came with the trappings of television: Davina McCall hosted, and Simon Cowell gave his verdict on the finalists. The business audience included people behind Google, LinkedIn, Skype and Uber. For Turner, the important discovery was that this world existed at all. There were people whose job was to help a proposal leave the page. You could bring them a problem, explain an approach and ask them to back the attempt.
Today she is co-founder and chief executive of Gameto, based in Austin. Her company announced a $44 million Series C in August 2025. Those numbers make the student competition look small, as student competitions generally do once somebody starts attaching eight figures to the story. But the earlier event helps explain the later career. Turner had encountered a way of working that suited her: science alongside business, operations and the awkward business of persuading other people.
A much larger map
She was born in Niš, in southern Serbia. Her father was a professor and her mother a fashion model. Mathematics and science became her territory early. She competed across mathematics, physics, biology and chemistry, then moved to Britain and studied at UCL. It was a move across countries, but also across the range of careers she could imagine for herself.
A promising young scientist can spend years learning the names of established professions without meeting someone who has invented a job of their own. Turner’s route put her among entrepreneurs while she was still a student. The contrast mattered. Academic progress has courses, examinations and recognizable stages. Starting a business requires someone to propose the next stage and persuade others that it deserves to exist.
At UCL, she earned the Meyerstein Scholarship for performance in her first two years, collected multiple certificates of merit and placed in the top one percent of her class. Alongside that work, she mentored younger students. Her teacher Lucie Clapp praised her determination, her enthusiasm for communicating with people from different backgrounds and her good humor. Ambition had room for both the mark at the top of her own paper and the person coming up behind her.
The competition added a different kind of feedback. An idea had to survive outside the university and make sense to an audience with its own interests. A brief entry became a presentation; the presentation became conversations. The encounter offered a practical introduction to company building, with considerably less opportunity to hide behind an impressive bibliography.
Learning to sit on both sides of the table
Her work subsequently took her through research posts at King’s College London and the Buck Institute. She also became a partner at SALT Bio Fund. Research and investing ask different questions of the same idea. One asks what the evidence establishes. The other must also ask who will build the organization, how much it will cost and who might finance the next stretch.
Being able to move between those questions is useful preparation for a founder. A result can be interesting without supporting a company. A company can be attractively presented without possessing a convincing result. Turner’s career placed her close to both the underlying work and the decisions about which teams would receive money to continue it.
She also co-founded Hooke, working in collaboration with the Buck Institute’s Eric Verdin. The recurring activity was assembling people around research: finding colleagues, establishing an organization and giving a scientific project a structure beyond an individual researcher’s desk. By the time Gameto arrived, she had already tried more than one seat in that arrangement.
That background gives her founder story a useful complication. She had experience evaluating other companies before taking responsibility for one as chief executive. There is an appealing neatness to that sequence. There is also a trap: recognizing somebody else’s difficult decision is easier than making your own with a payroll attached. Expertise can shorten the introduction. It cannot remove the job.
From an apartment to a company
Turner co-founded Gameto in 2021 with entrepreneur Martin Varsavsky. The company’s early work connected it with George Church’s laboratory at Harvard. Years later, looking back on the beginning, she recalled an early presentation assembled in her first rented New York apartment. It is a useful image because it restores the small scale of a beginning that later funding totals can obscure.
A deck is a curious object. It can contain an entire company before there is much company to contain. The founders have to turn its proposed relationships into actual ones: researchers who join, investors who commit and colleagues who will spend their working lives on the plan. The slide announcing a team is particularly easy to write before the team exists.
Gameto’s organization now includes scientific, manufacturing, legal, finance and commercial expertise. Christian Kramme serves as chief scientific officer; Bruna Paulsen leads manufacturing. Varsavsky is chairman. Those titles describe a division of labor that an early pitch can only anticipate. They also place Turner’s role in proportion. Being CEO means making other people’s specialized work fit together.
The Harvard connection continued beyond the founding period. In January 2026, Gameto announced another intellectual property license from the university. The relationship has therefore involved the practical machinery of company building as well as the original research connection. Collaboration acquires agreements, responsibilities and a future that someone must organize.
The company gets more expensive
In May 2024, Gameto announced a $33 million Series B led by Two Sigma Ventures with RA Capital. Existing backers included Insight Partners, Future Ventures and BOLD Capital Partners. The investor group also brought in Olivia Walton’s Ingeborg Investments, alice + olivia founder Stacey Bendet Eisner and Frida founder Chelsea Hirschhorn.
The list is interesting for its mixture of backgrounds. Alongside specialist investors were founders who had built businesses with direct relationships to customers. Company building often requires several sorts of fluency at once. The person examining the research and the person thinking about how an organization presents itself may be asking equally necessary questions in quite different languages.
August 2025 brought the $44 million Series C, led by Overwater Ventures. Insight, RA Capital, Two Sigma and other existing investors participated. There was a progression here beyond the larger cheque: a company that had attracted backers had persuaded several of them to return. Repeat participation is a concrete event. The eventual return on that investment remains work for the future.
Fundraising makes a very convenient chapter break in a business story. A date, a number, a set of names: everything fits neatly in a paragraph. Spending the money well is less accommodating to the form. It happens through recruitment, contracts, schedules and decisions that rarely arrive with a photograph. For Turner, each new round expands the work of running the organization.
A small, expensive word
Ask what she has learned as a CEO and one answer is the ability to decline. She has described becoming better at recruiting and more confident about saying no. It is an unglamorous piece of professional development, especially in a culture fond of celebrating people who say yes to everything. Yet an organization pays for an uncertain yes in time as well as money.
“I’m much, much better at saying no.”
Dina Turner, 2025
A founder’s early talent may be opening doors. Running the company requires choosing which ones the team should actually walk through. The same applies to hiring. Turner has talked about finding people who can grow into the expertise the organization needs. A small business cannot always buy the fully finished version of every specialist. It must judge potential and provide the conditions for it to develop.
Through her family office Turner Venture Holdings, she participates in other deep technology startups as a founder, director, investor and adviser. The student who discovered the entrepreneurial community has become someone working within it in several capacities. The range is wider; the question of where to put her attention becomes more consequential.
The next room
Public recognition followed the work. Forbes included her in its 2023 Under 30 class. BioSpace named her among its 2025 40 Under 40 honorees. Onstage appearances have included the Forbes 30/50 Summit, where she joined Illumina executive Susan Tousi in a conversation moderated by Maggie McGrath. The student presenting to established business people was now sharing the programme.
Her public presence also includes a much smaller setting: a conversation on her younger sister Nadia’s podcast. The two scales belong in the same portrait. A founder may spend one day explaining a company to investors and another talking with a sibling. The title travels between those rooms; the relationships in them remain different.
The 140-character submission is a good place to return because it makes the distance measurable without turning a career into a fable. There was a specific competition, a student, an app proposal and a runner-up place. Then came research, investing, collaborators and years of running a company. Each step involved people who could offer something she did not yet have.
Turner’s career keeps widening the circle around an idea. First she had to get it into a sentence. Then she had to explain it to a room. Now she has to give a company enough direction, money and capable colleagues to keep working after the presentation ends. The slides, at least, are no longer doing all the heavy lifting.
