Top awardedWe're Outfly, the AI Acceleration Agency, and a B Corp based in Londong. Since 2010 we've been helping companies get off the ground and grow: building new ventures, finding their first customers, then scaling them. Between them, the 157 businesses we've helped scale have raised £449m, they're now worth £4.2bn combined, and £2.6bn has come from exits. he work runs from the story to the spreadsheet. On one side, a brand and a proposition people want to talk about and buy into. On the other, the campaigns, data and tracking that bring acquisition costs down and leads in. Our own AI takes on the research and the first drafts, so our strategists, designers and venture builders spend their time on the judgement calls that decide whether it works. We're a certified B Corp in Shoreditch, working with startups, scale-ups, established organisations and investors in the UK and around the world. If you're weighing up what to do next, book a 30-minute call. Even if we never work together, you'll have sixteen years of building ventures and brands on your side for half an hour, and it won't cost you anything.Looking for work in IntegrationLocated in London, United KingdomFrom €10,000 for IntegrationWorked in Media (+12)Speaks English11-50 membersBullshark

(0 review)Conversations that act. AI agents for customer service, retention and sales, built and run for you.
Fiveleaf is a UK company that designs, builds and runs AI agents for service businesses with high customer volume: broadband and telecoms first, and increasingly energy, housing, insurance, retail and subscription businesses. We build three kinds of agent on one shared foundation. Inbound agents answer customers on web chat, WhatsApp, email, SMS and voice, around the clock. Triggered agents start the conversation when something happens in your systems, such as a contract nearing its end or a customer starting to switch, and turn the reply into a full conversation. Internal agents help your own team, from call quality assurance to reporting. Every agent works inside the systems you already run. It verifies the customer, pulls their account from your CRM or billing platform, resolves the issue from your own knowledge and policies, and acts: raising tickets, booking callbacks, applying renewals and retention offers, capturing and qualifying prospects. When a person is needed, it hands over with the customer verified, the account loaded, the issue captured and the transcript attached, so your team reads a brief instead of the backlog. We work build-then-run. A fixed-fee build takes the first agent live in four to eight weeks, including the shared platform. Every agent after that reuses it, so the second goes live in one to three weeks and later ones faster still. After launch we host, monitor and improve the agents every week, as part of the monthly service rather than an extra. We equip your team rather than replace it. For a UK fibre broadband provider, the platform returns around 5:1 a month on the investment, and 71% of cancellation requests handled through it are saved. Every figure is verified against the client's own operational data. Every engagement runs through the founder personally, from the first call to the agent running live.Looking for work in IntegrationLocated in London, United KingdomFrom €3,000 for IntegrationWorked in TelecommunicationsSpeaks English1-10 membersBird Marketing

(0 review)Business automation and AI for UK construction companies and law firms
Severus (severus.co) is a UK business automation and operations partner for construction companies and law firms, with offices in London and Tallinn. Founded in 2021, we work on one principle: strategy before software. Most companies have already bought the software and are still waiting for the result. We start from the other end. Together with you we define the outcome your business needs, written on one page with a metric, a baseline from your own data, a target and a date. Then we design the best route to it, with every option costed and the risks mapped upfront, and implement the software that gets you there at a fixed price and timeline once the design is agreed. Sometimes that means connecting the tools you already have (Procore, COINS, Sage, Xero, Microsoft 365), sometimes building custom software, and sometimes adding AI inside your own environment, only where it pays for itself. Recent outcomes: a connected cost-control system for a construction firm (cost leakage down 68%, month-end from three weeks to three days, ROI in seven months); AI-assisted construction contract review (from days to about three hours per contract); a gold savings platform grown from 500K to 1.5M+ users; automated payment chasing on Xero and QuickBooks data, live in five months.Looking for work in IntegrationLocated in London, United KingdomFrom €5,000 for IntegrationWorked in Legal Services (+1)Speaks English11-50 membersBryter Digital Limited
