Not a tool. Not an agent waiting for instructions. A colleague with a job to own, and a human boss to answer to. Synths are named, role-defined AI entities with persistent memory. They communicate like humans, operate inside the tools your team already uses, and earn trust through reliability and transparency, handling the cognitive workload so your people focus on judgment, creativity and relationships.
Available now. £500/mo per full-time colleague. No setup fee. See pricing →
Alfred sent this himself. No one asked.
Each Synth has a name, a role and a job to own, modelled on the way a great teammate would work.
Vision Meditech built every quote by hand. A Synth named Wallace turned hour-long replies into minutes.

Four things separate an AI colleague from yet another tool.
Talks like a colleague in plain language, right inside the tools your team already uses: no prompting rituals, no new platform to learn.
Stable identity, persistent memory, explains its reasoning, and escalates to its human boss when needed.
Handles the mechanisable so your people do judgment, creativity and relationships.
Acts on a schedule and on triggers: drafts the bid, chases the quote, updates the record before you ask.
Synths draw on a shared library of capabilities, combined and configured for each role.
Has read all your documents, emails and CRM data, and points you to what you need in seconds.
Answers customers in your brand voice, around the clock, straight from your own knowledge.
Watches the market, your rivals and the chatter, so you spot risk and opportunity first.
Greets and qualifies website visitors 24/7 with the depth of your top salesperson.
Feeds the right spec, price or policy into the call the moment it's needed.
Runs intake and feedback conversations, then hands you clean, structured answers.
Carries multi-step processes to the finish, using judgment and checking in only when it should.
Synths onboard the way a person would: given a role, plugged into your systems, and trusted incrementally.
We give each Synth a name, a role and a clear remit, configured with your terminology, brand voice and the guardrails you set.
They connect to the tools you already use (Google Workspace and Slack) and work where your team works.
Autonomy expands as trust is earned. Every interaction is logged (what was asked, answered and which knowledge was used) with a full audit trail.
Two product leaders who spent their careers building technology businesses, from bootstrapped startups to Fortune 500 brands. Now they're building Frntir.
Aidan co-founded Frntir in 2024 to give mid-sized businesses AI colleagues they can put to work.
He has led a startup before: an InnovateUK-funded venture that used predictive analytics to transform the road haulage market. Across 25 years he has also built products for a string of early-stage companies at hedgehog lab, and held Head of Product Strategy, Chief Product Officer and Chief Commercial Officer roles.
Aidan holds a B.Sc. (Hons) in Mathematics and an Executive MBA (cum laude).

Cyril co-founded Frntir in 2024 after twenty years building product organisations inside fast-growing companies in fintech, eCommerce, marketplaces and AI.
As VP of Product at TransferGo he rebuilt the product organisation and launched a neo-bank in nine months. At Zoopla he moved a siloed, feature-driven business to a product-led way of working that reignited growth.
Cyril holds an MBA from The Open University and works in English and French.
LinkedIn →They started Frntir after watching too many mid-sized businesses buy AI that needed a consulting project to switch on. A Synth should be a colleague you hire, not a programme you run.
Start this month, or book a call and we'll show you the Synth that fits your biggest bottleneck.
