Synthflow AI is bringing 'conversational' voice agents to call centers. Read the pitch deck that it used to raise $20 million.
Synthflow, a startup that has built AI voice agents that can hold "natural-sounding" phone conversations with customers, has raised $20 million in funding.
The Berlin-based startup's platform lets enterprise customers create and deploy AI voice agents without coding expertise. Companies can customize those agents to handle simple inquiries, customer support, and follow-up with actions like appointment scheduling.
"You can think of Synthflow as a voice AI platform on a no-code basis that allows businesses to very easily and quickly build and deploy voice AI agents," Hakob Astabatsyan, cofounder of Synthflow, told Business Insider.
Astabatsyan said his startup's tech can replace traditional automated call menus, in which users press buttons to select options. Instead, Synthflow's technology is built on large language models that can have "real-time contextual conversations," Astabatsyan said.
In a demo video seen by BI, an AI agent answers a call from a customer seeking a car insurance quote. The AI agent asks for the customer's details in a relaxed, conversational tone before transferring to a human operator. Astabatsyan said the AI agent's responses come in under 400 milliseconds, which matches the human brain's processing speed for conversations.
Astabatsyan founded Synthflow in 2023 with Albert Astabatsyan and Sassun Mirzakhan-Saky. The startup says it now has over 1,000 enterprise clients, often in call centers, in areas such as finance, healthcare, and education. It also offers its tech on a white-label basis and can integrate into a company's existing telephony system.
Voice has become a key battleground among AI startups, with companies like ElevenLabs and PolyAI also raising millions in capital to develop AI for call centers.
Astabatsyan said that fundraising for AI startups is "definitely not easy" because the expectations are "very, very high."
He added that investors expect AI startups to grow "two times faster" than benchmarks from a few years ago.
Synthflow's Series A round, which was led by Accel with participation from Atlantic Labs and Singular, brings the startup's total funding to $30 million. Synthflow plans to use the fresh funding to open a new US office and invest in developing its agent platform.
BI got a look at the 10-slide pitch deck it used to secure the fresh funding.

Bumble to lay off 30% of workforce as dating company moves to slash costs
Bumble will lay off roughly 30% of its workforce, or 240 employees, according to a regulatory filing filed by the online dating company on Wednesday. The jobs cuts come as the company moves to reduce costs and refocus on growing its customer base. Bumble estimates the layoffs, which are slated to take place in the second half of the year, will save $40 million. The Texas-based company said it will reinvest most of that money into "product and technology development." In announcing the decision to staff on Wednesday, Bumble CEO Whitney Wolfe Herd, who also co-founded Tinder, said the online dating business as is at an "inflection point." "The reality is, we need to take decisive action to restructure to build a company that's resilient, intentional and ready for the next decade," she wrote in an email to Bumble employees. In a statement to CBS News, a Bumble spokesperson said the decision to reduce the company's workforce is in line with the company's strategic goals. "Our focus now is on moving forward in a way that strengthens our core business, continues to serve our members effectively and positions us for future growth," the spokesperson said. Bumble said in its securities filing that it will incur $13 million to $18 million in non-recurring charges for severance and other benefits paid out to impacted employees. Shares of the online dating company were up 21% in midday trading. During a company earnings call in May, Herd acknowledged Bumble had lost traction with customers and said it was focusing on providing users with better matches. "We are accelerating our efforts to improve our member base and show members a more thoughtful selection of high-quality relevant profile," Herd said at the time. "As we execute on our plans, we are very focused on building a sustainable revenue model with a healthy paying member base," she added.

Bernie Sanders says that if AI makes us so productive, we should get a 4-day work week
As AI companies rave about how their products are revolutionizing productivity, Senator Bernie Sanders (I-VT) wants the tech industry to put its money where its automated mouth is. In a recent interview with podcaster Joe Rogan, Sanders argued that the time saved with AI tools should be given back to workers to spend with their families. 'Technology is gonna work to improve us, not just the people who own the technology and the CEOs of large corporations,' Sanders said. 'You are a worker, your productivity is increasing because we give you AI, right? Instead of throwing you out on the street, I'm gonna reduce your work week to 32 hours.' It's a concept that would be a relief to most people, and an abject horror to anyone who has ever been to Davos. What's the point of life if you don't take every moment you can to drive shareholder value? For the tech elite, the promise of AI-driven increases in productivity means that companies can do even more, since their workers will be freed up to take on even more tasks — or, they can save money by just slashing their headcount. But for workers, this boost in efficiency could mean completing their existing workloads in less time with no loss in pay, so maybe if they're lucky, they can make it to their kid's Little League game. 'And by the way, not a radical idea,' Sanders said. 'There are companies around the world that are doing it with some success.' In the United Kingdom, for instance, 61 companies (around 2,900 workers) piloted a four-day work week in the latter half of 2022. Out of 23 companies that shared financial data, the revenue from the beginning to the end of the trial remained about the same, rising by 1.4% on average.

Boston, MA | REGISTER NOW Kickstarter has operated on a four-day work week since 2021, while Microsoft Japan piloted a four-day work week in 2019, which led to a reported 40% increase in productivity. 'Let's use technology to benefit workers,' Sanders said. 'That means give you more time with your family, with your friends, for education, whatever the hell you wanna do.'
