Do I have to tell my endorsing body if I bring on a co-founder?

There is no single universal rule published by every body, but a material change to ownership or team structure is exactly the kind of thing endorsers expect to hear about proactively rather than discover at a contact point meeting. Treat it as disclosable and raise it early.

Will adding a co-founder reduce my equity below what's expected for the visa?

There's no fixed minimum equity percentage written into the Innovator Founder rules the way there was under the old Innovator route, but your endorsement was granted to you as a genuine, hands-on founder. A stake so diluted that you look more like an early employee than a founder is the real risk, not a specific percentage threshold.

Can my new co-founder also apply for their own Innovator Founder visa?

Only if they independently go through endorsement themselves — one person's endorsement does not extend to another. If they need UK immigration status to work in the business, that is a separate application on its own merits, potentially through a different route entirely depending on their circumstances.

What if the co-founder is joining without being on the endorsed business plan at all?

That's the version endorsing bodies are most likely to query, because it wasn't part of what they assessed. Update your endorsing body before a review surfaces it as a surprise, and be ready to explain why the addition strengthens rather than dilutes your role.

Does a co-founder joining count against the two-of-seven growth criteria for ILR?

Job creation is one of the recognised achievement categories toward settlement, but a co-founder is different from an employee — they typically hold equity and governance rights rather than being a hire. Don't assume adding a co-founder automatically ticks a job-creation box; check the current criteria and how your endorsing body treats it.

Adding a co-founder after you've already been endorsed

Most founders who go through endorsement solo do it because that's simply how the business started. Somewhere in year one or two, a need emerges that a co-founder would solve cleanly — technical expertise you don't have, a second person to carry operational load while you focus on strategy, or simply someone who's earned equity through work already done. The idea itself is rarely the hard part. The hard part is doing it without quietly undermining the exact thing that got you endorsed: that you, personally, are the genuine, hands-on entrepreneur driving this business.

Why this is different from a normal hire

Hiring an employee, even a senior one, doesn't touch the core premise of your endorsement — you remain the founder running the business, and staff work for you. A co-founder is structurally different because they typically hold equity, sit closer to governance, and in the founder's own narrative starts to share credit for direction and strategy. None of that is disqualifying. But it changes what an assessor sees when they look at your cap table and your account of who does what, and it's worth being deliberate about both.

Equity and the cap table

There's no single number that defines "founder enough" under the current Innovator Founder rules — that's a departure from the older Innovator route, which had a more explicit minimum shareholding requirement in places. That doesn't mean equity is irrelevant to how your standing will read. A few practical points:

Document the rationale, not just the split. If you're giving a new co-founder 30% for bringing in technical capability the business genuinely needed, write that down in board minutes or a founders' agreement at the time, not retrospectively when a contact point meeting asks about it.
Keep your own stake and role legible. If your equity drops significantly, be ready to explain what it bought the business and why your own involvement remains substantive despite the smaller percentage.
Vesting matters for your story, not just for protecting the business. A co-founder on a standard four-year vesting schedule with a cliff signals a considered decision. Someone handed a large stake with no vesting on day one, with limited track record, is harder to explain if questioned later.

Should you tell your endorsing body?

Yes — proactively, and before it becomes something they discover. See tell your endorsing body before they ask for the broader principle: material changes to the business are far better received as something you flagged than something a reviewer had to dig for. Adding a co-founder, particularly one taking meaningful equity or a formal director role, sits squarely in "material change" territory.

Founders who call ahead of a change look like they're running the business deliberately. Founders whose changes get discovered look like they're being run by events.

— A recurring theme across contact point feedback

There's no universally published protocol across UKES, Envestors, and Innovator International for exactly how to notify a co-founder addition — this is one of the areas where practice varies by body and even by case handler, so the honest answer is: ask your endorsing body directly what they want to see, rather than assuming a format. If in doubt, a short written update explaining who's joining, what equity they're taking, what role they'll hold, and why it strengthens rather than dilutes the business is a reasonable default while you wait for their guidance.

Keeping your own centrality clear

The practical safeguard against the dilution risk isn't legal — it's evidentiary. Build a habit of being able to demonstrate, at any point, what you specifically did in the last quarter: decisions you made, deals you closed, product calls you drove. This is the same discipline that underpins monthly trading reports and the living business plan — a business plan and reporting rhythm that reflect what's actually happening, including who's actually doing it.

If your co-founder is taking on the parts of the business you're weaker at — technical build, for instance — while you remain the one setting strategy, owning customer relationships, and representing the business externally, that's a strong and easily told story. If the lines blur so that either of you could plausibly be described as "the founder," that's the scenario to actively manage against.

What to watch for at the next contact point

Reviewers at contact point meetings are looking at progress against the originally endorsed plan. A co-founder who wasn't part of that plan is a variance worth explaining clearly rather than mentioning in passing. Come prepared with:

A short, direct explanation of why the co-founder joined and what gap they filled.
Documentation of the equity split and any vesting terms.
A clear, specific account of what you personally have continued to do — not a general assertion that you're "still very involved."
If the co-founder has taken on a formal director role at Companies House, be ready to show that filing alongside the explanation.

Key takeaways

Adding a co-founder after endorsement is not prohibited, but it changes what an assessor sees on your cap table and in your account of who runs the business.
There is no fixed minimum founder equity percentage under current rules, but a stake diluted to near-employee status is a genuine risk to your standing.
Disclose material co-founder additions to your endorsing body proactively, before a contact point meeting surfaces it as a surprise.
Document the rationale, equity split, and vesting terms for the addition at the time, not retrospectively.
Keep concrete, specific evidence of your own ongoing hands-on role — general assurances that you're "still involved" won't hold up under scrutiny.
