We built this for UK Ltd contractors first. Now we are pointing the same engine at early-stage companies — R&D relief, SEIS/EIS, share options and the runway question — with the same figures traced to statute and the same qualified accountant signing them off. This part is not open yet. Register below and we will tell you the day it is.
One email when Nebula opens to startups — nothing else. No commitment, no card.
We'll be in touch as Nebula opens to startups. In the meantime the IR35 Hub is free to use right now, and the contractor service is further along.
Every figure comes from the tax rules themselves — the AI is never allowed to invent one — and a qualified accountant signs off every filing and figure we produce for you. (The free IR35 Hub is automated end to end.) None of the below is open yet; this is what we are building toward. We are accountants, not financial advisers: we prepare and sign the tax and company work, we do not advise on investments.
A claim under the merged scheme is not a spend figure — it needs a technical narrative and an apportioned cost base that survives an HMRC look. We build both, from your own records.
Advance assurance before the round, compliance statements after it — the paperwork that lets your investors actually claim their relief, prepared and signed rather than left to chase.
Options granted without an agreed valuation and a timely notification quietly lose the tax treatment they were granted for. We handle the valuation, the notification and the paperwork behind it.
Burn, runway and the cap table alongside the statutory accounts — with money owed to HMRC set aside first, because investor cash in the bank is not the same as profit.
