Two London startups raised a combined $46M, and both build the same thing: autonomous AI agents that do work rather than suggest it. The pattern is hard to miss. Gradient Labs doubled its Series A to $26M to run customer operations for banks and fintechs. Airspeed pulled in $20M to take on the grind of revenue teams. Both were started by people who built serious AI elsewhere, one team out of Monzo and the other out of Google DeepMind. Both are spending the money to push into the United States.

Gradient Labs Doubles Its Series A To $26M For AI Finance Agents ### Deal Overview - Stage: Series A, doubled from an original $13M round - Sector: Fintech, AI customer operations - Geography: London, United Kingdom - Round size: $26M - Lead investors: Octopus Ventures and CommerzVentures ### Investor Profile Octopus Ventures and CommerzVentures came in as new leads, joined by follow-on money from Redpoint Ventures and Exceptional Capital. Redpoint led the original $13M round in July 2025. CommerzVentures brings a fintech-only investing record, which fits a company selling into regulated finance. Doubling an existing round rather than waiting for a fresh one signals real conviction. Investors don’t add to a position after a quiet year. They do it after the numbers move. ### Company and Leadership [Gradient Labs](https://gradient-labs.ai) was founded in 2023 by Dimitri Masin, Neal Lathia, and Danai Antoniou. All three were early members of Monzo’s AI and data science team. That background matters here. Running AI inside a regulated bank taught them what compliance, audit trails, and risk controls actually demand, and that knowledge shapes the product. ### Problem and Opportunity Financial firms handle huge volumes of regulated customer work: support tickets, lending decisions, disputes, KYC checks, and voice calls. Most of it is manual, slow, and expensive. Generic chatbots can answer simple questions but can’t be trusted with the steps that carry regulatory weight. Gradient Labs is built for exactly those steps. ### Product and Technology The company builds vertical AI agents that run customer operations end to end. The agents plug into existing systems rather than replacing them, and they handle long, multi-step workflows instead of FAQ replies. They process hundreds of thousands of voice calls a month. Gradient Labs reports up to 98% customer satisfaction and 900% year-over-year revenue growth. Serving more than 32 million end users through its customers gives it a steady stream of regulated-operations data that sharpens the agents over time. ### Use of Proceeds and Vision The fresh capital funds a faster push into the US, where Gradient Labs already works with Stash, Rho, and Current. Money also goes toward letting the agents take on more complex tasks. Masin describes the goal as building “the agent layer that financial services need to run their customer operations autonomously.” ### Market Context European AI-agent startups are chasing a market projected at $52B. Gradient Labs sits against well-funded horizontal players like Sierra, which closed $950M at a $15.8B valuation, and Decagon, which raised a $250M Series D. Its edge is narrowness. By focusing only on regulated finance, it sells something the generalists can’t easily match. Existing customers include Wise, Monzo, Zego, and Pockit in Europe, plus US fintechs. ## 2. Airspeed Raises $20M To Build An AI Execution Layer For Revenue Teams ### Deal Overview - Stage: Series A - Sector: SaaS, AI for go-to-market - Geography: London, United Kingdom, with a New York office - Round size: €17.2M ($20M) - Total funding to date: over $25M - Lead investor: DN Capital ### Investor Profile DN Capital led the round, with Vi Partners, Framework Venture Partners, and Atlassian Ventures joining. Atlassian Ventures is worth a look here. It backs software that lives inside daily work, and Airspeed wants to live inside the systems sales teams use every day. The mix of European and strategic investors supports a company splitting time between London and New York. ### Company and Leadership [Airspeed](https://www.goairspeed.com) started as Glyphic in 2022 and rebranded on 20 May 2026. Founders Adam Liska (CEO) and Devang Agrawal (CTO) are former Google DeepMind research scientists. Liska holds a PhD in brain and cognitive sciences and worked at Spotify, Facebook, and IBM. Agrawal is a Cambridge engineering graduate and former Apple machine learning engineer. The team has since hired from Meta, Apple, and Spotify. ### Problem and Opportunity Sales tools have long been good at describing what happened and bad at doing anything about it. Reps still update records by hand, chase follow-ups, and miss deal risks buried in scattered systems. Airspeed wants software to take those actions instead of just flagging them. ### Product and Technology Airspeed builds an agent-native go-to-market platform. Its agents act on commercial context across calls, emails, support tickets, and CRM records, then update records, flag risks, draft follow-ups, and coordinate work across teams. At the center is what the company calls a “commercial brain,” a persistent memory layer that pulls go-to-market knowledge out of fragmented systems and into one place, with guardrails and evaluations around what the agents do. Customers built thousands of custom agents in the first four months of 2026, and monthly run volume nearly tripled between January and April. ### Use of Proceeds and Vision The $20M scales the technology, funds global hiring, and grows the US presence run from its New York office. The raise follows a year in which Airspeed doubled headcount and quadrupled revenue. The company frames itself as a “system of action” that closes the gap between the CRM, which holds the record, and revenue intelligence, which holds the insight. The aim is software that turns commercial data into the actions that move deals forward. ### Market Context Grand View Research valued the AI-for-sales market at $24.64B in 2024 and projects $145.12B by 2033, a 22.2% annual growth rate. That makes sales and marketing the fastest-growing slice of the broader AI market. Airspeed competes with AI sales-rep startup 11x, revenue intelligence leader Gong, valued above $7B, and sales suites Salesloft and Outreach. It serves 200 customers across 20 countries, including Persona, Pricefx, Qdrant, and Foleon. ## Lessons For Founders - Narrow beats broad in crowded AI markets. Gradient Labs holds its own against bigger rivals by doing one regulated thing well rather than everything passably. - Operating background sells. Both teams turned hard-won experience into a reason to trust their agents: regulated fintech at Monzo, AI research at DeepMind. - Agents that act are worth more than tools that advise. Both companies charge for doing the work, not for surfacing insights about it. - A doubled round can beat a new one. Gradient Labs extended its Series A instead of raising fresh, a fast way to add capital and new leads when growth is strong. - Pick the US early. Both London firms are spending this money to expand stateside, where the biggest customers and budgets sit.
