E-commerce firm Rokt appoints former mParticle leader Sam Dozor as Chief Technology Officer
Rokt has announced the appointment of Sam Dozor as Chief Technology Officer. Dozor brings more than 13 years of experience building mParticle, a customer data platform, prior to its acquisition by Rokt in 2025. The mParticle CDP is now the foundation of how Rokt clients activate data, deliver real-time decisions, and help drive more value from every customer interaction.
"We are in the middle of the most significant transformation in how software is built in a generation," says Bruce Buchanan, CEO at Rokt. "AI has collapsed the cost of experimentation and compressed innovation cycles from quarters to weeks, handing a structural advantage to the companies that adapt fastest. Sam's mandate is to make Rokt the fastest building, most technically excellent engineering organisation in our category."
Dozor will lead engineering across Rokt, including platform infrastructure, developer experience, and security. His mandate is to accelerate how quickly new capabilities are built and deployed, while ensuring the platform scales to meet the demands of global enterprise clients.
"Rokt is building for where the industry is going, not where it's been," says Dozor. "Clients don't win by having more data. They win by having the right data and using it faster and more intelligently. That's the opportunity in front of us, and it's what we're focused on delivering for every client."
2026 RTIH Innovation Awards
E-commerce technology will be a key focus area at the 2026 RTIH Innovation Awards.
The awards are now open for entries and celebrate global retail technology innovation in a fast moving omnichannel world.
Our winners will be revealed at the 2026 RTIH Innovation Awards Ceremony, taking place at The HAC in Central London on Wednesday, 4th November.
Check out our 2025 winners here.
Our 2025 hall of fame entrants were revealed during a sold out event which took place at The HAC on 16th October and consisted of a drinks reception, three course meal, and awards ceremony presided over by award winning comedian, actress and writer Tiff Stevenson.
In his welcome speech, Scott Thompson, Founder and Editor, RTIH, said: “This is the awards’ fifth year as a physical event. We started off with just 30 people at the South Place Hotel not far from here, then moved to London Bridge Hotel, then The Barbican, and last year RIBA’s HQ in the West End.”
“But I’m conscious of the fact that, to quote the legend that is Taylor Swift, You’re only as hot as your last hit, baby. So, this year we’ve moved to our biggest venue yet, and also pulled in our largest number of entries to date and broken attendance records.”
He added: “This year’s submissions have without doubt been our best yet. To quote one of the judges: The examples of innovative developments across both traditional and digital retail spaces were truly remarkable.”
Congratulations to our winners, and a big thank you to our sponsors, judging panel, the legend that is Tiff Stevenson, and all those who attended our 2025 gathering.
