Manage 100+ clients at scale.
A personal assistant for every team member, without additional headcount. Multi-client, multi-user.
Trusted by forward-thinking fiduciaries.
Growth without proportional team growth
More clients bring more revenue – but qualified professionals are scarce.
Skilled labor shortage
An open position for 4 months – not a single qualified application. Your existing staff is at their limit, and finding new talent is nearly impossible.
Senior time spent on routine work
Instead of interpretation and advisory, experienced professionals are busy with reconciliations, rebookings, and other daily recurring tasks. It is expensive, demotivating – and only scales with more headcount.
Bottleneck: closing season
100–200 overtime hours per employee by end of March that somehow need to be compensated in Q3. Valuable time missing from client service.
Multi-client, multi-user – built for firms
One-on-One – AI assistant for accounting and controlling
Tax questions answered simply. Accruals prepared and posted. Liquidity planning exported to Excel. Complex audit requests via PDF upload. Offer your clients more, without more effort on your side.
