Kastren Fundast dashboard concept showing cash analysis for a small business

Put idle business cash to work, with decisions you can check

Kastren Fundast analyses your cash position with predictive models and recommends how much surplus to deploy, and when. Every recommendation is written into a public performance log, so you can review the reasoning before you rely on it.

Recommendations are reviewed by an independent community of finance professionals before they are published, not after.

The problem

Why cash sits idle, and why that's a data problem

Most small businesses keep more cash in low-interest accounts than they need for day-to-day operations. This is rarely a choice made on purpose. Building a proper case for deploying surplus cash usually means pulling together cash flow forecasts, receivables timing, and market conditions, then interpreting them without a finance team on hand.

Kastren Fundast was built to shorten that process. Our models read your cash flow history, upcoming commitments, and relevant market signals, then translate them into a plain-English recommendation with a stated level of confidence. You still make the decision. We simply remove the manual analysis that usually stands in the way of it.

Illustrative example only. Actual proportions depend on your cash flow data and risk tolerance.

Core capabilities

Three functions working from the same data

Rather than separate tools, Kastren Fundast runs predictive modelling, risk monitoring, and reporting from one continuously updated data set, so recommendations stay consistent as your figures change.

Predictive modelling

Our models study your historical cash flow, seasonal demand patterns, and current account balances alongside publicly available indicators such as Bank of England rate movements. The output is a forecast range for surplus cash over the coming weeks and months, not a single fixed number.

  • Rolling forecasts updated as new transaction data arrives
  • Confidence ranges shown alongside every projection
  • Scenario comparisons for different deployment amounts

Real-time risk mitigation

Once cash is deployed, the same models keep monitoring it. If market conditions shift, or your own cash flow forecast changes, you receive a flagged review rather than a silent report buried in a monthly summary. Thresholds are set with you, so alerts reflect your own risk appetite.

  • Continuous monitoring against your stated risk limits
  • Early flags when forecasts move outside expected ranges
  • Stress-testing against adverse scenarios on request

Automated reporting

Every recommendation and outcome is compiled into a board-ready summary written in plain English, with the underlying figures available for anyone who wants to check the working. Reports are generated automatically, so nobody on your team spends an afternoon formatting spreadsheets.

  • Plain-English summaries alongside the raw figures
  • Exportable reports for board packs and audits
  • A running record of past recommendations and outcomes
Methodology

How "community-verified" works in practice

Transparency is easier to promise than to demonstrate. Here is the process a recommendation goes through before it reaches you, and what happens to it afterwards.

1

Data submission and scoping

You connect your accounting or banking data, and set the risk boundaries you're comfortable with.

2

Model output and internal check

The model produces a recommendation, which is checked against your stated constraints before release.

3

Community review

An independent panel of finance professionals reviews the model's reasoning and flags anything unclear.

4

Public logging

The recommendation and its eventual outcome are recorded in the public performance log, in full.

The methodology behind the models is reassessed on a fixed schedule, and any material change is noted alongside the log so past recommendations remain understandable in the context they were made.

Applications

Where this fits into a small business's decisions

The same underlying models are applied to a handful of recurring situations UK small business owners bring to us.

Treasury optimisation

For businesses holding more operating cash than current activity needs, we identify how much could reasonably be deployed into lower-risk short-term options without disrupting day-to-day liquidity.

Strategic expansion analysis

Before committing cash to new premises, equipment, or hiring, our models test whether reserves can absorb the commitment under a range of trading scenarios, not just the most likely one.

Market volatility shield

During periods of interest rate or market movement, recommendations are automatically re-checked, so previously sound decisions are revisited rather than left to age unreviewed.

Common questions

Before you get in touch

These are the questions we're asked most often by SME directors evaluating whether to submit their data.

How is our financial data stored and protected?

Data is encrypted in transit and at rest, and stored on infrastructure located in the UK to align with your existing data residency obligations. Access is limited to the systems and reviewers directly involved in producing your recommendation. You can request deletion of your data at any time, in line with UK GDPR.

How long does integration take, from first contact to a recommendation?

Most businesses connect their accounting software and provide an initial data set within the first week. The model then needs a short period to build a reliable forecast baseline before the first recommendation is issued, typically within two to three weeks of connection, depending on data quality.

How accurate are the model's recommendations?

Accuracy is measured by comparing each forecast range against the actual outcome once it occurs, and this comparison is what populates the public performance log. Ranges narrow as more of your own data is available, but no forecast is a guarantee, and every recommendation states its confidence level rather than presenting a single fixed figure.

See the data before you decide

A data consultation walks through your current cash position, what a model-based recommendation would look like for your figures, and how the performance log works, before you commit to anything.
