Family office reporting has changed. The days of emailing Excel files between custodians, manually reconciling positions across spreadsheets, and presenting a static PDF once a quarter are numbered. Families are more sophisticated, portfolios are more complex, and the bar for service has never been higher.
What hasn't changed is the underlying challenge: investment data is fragmented, manual consolidation is slow, and too much of the team's time is consumed by administrative work instead of high-value oversight and relationship management.
Sesame One was built to solve exactly that. Here's how family offices are using it today, and what that looks like in practice.
Modern family portfolios span public equities, private equity, real estate, hedge funds, direct investments, and increasingly, passion assets like art, yachts, and collectibles. Each custodian, bank, and wealth manager delivers data in a different format, on a different cadence.
For many family offices, the result is a weekly or monthly ritual of downloading statements, reformatting data, manually entering transactions, and hoping nothing falls through the cracks. One London-based family office we worked with was manually updating valuations across hundreds of accounts. A process so labour-intensive it restricted portfolio updates to a monthly cadence and meant reporting could only cover net worth, not profit and loss.
That kind of operational bottleneck isn't just inefficient. It limits the quality of insight you can offer and the speed at which you can respond when it matters.
Sesame One connects directly to over 500 custodians and banks, establishing automated daily data feeds that consolidate, standardise, and enrich your data in one place. There is no manual download, no reformatting, no reconciliation ritual. Positions and transactions flow in overnight, ready for analysis by morning.
For private and non-custodied assets (private equity, real estate, direct investments, collectibles) Sesame's portfolio management system allows bulk input of transactions and valuation updates, with AI-powered document parsing to extract data from fund statements and capital call notices automatically.
The result is a single, trusted source of truth across the entire portfolio: liquid and illiquid, custodied and non-custodied, across every entity and currency.
"Sesame makes my life far easier. I can see everything in my portfolio in the detail I require and updated in real time, rather than a series of disparate and intermittent snapshots." — Sesame One client
Importantly, this data isn't held in a shared environment. Each Sesame One client operates within its own physically isolated database. This is a structural security commitment, not just a permission layer. Combined with ISO 27001 and SOC II certification, it's an architecture built to the standard that family offices and UHNW families rightly expect.
"When it comes to data security, Landytech have passed all our tests, and then some." — Simon Russell, CEO, Panthera Private Office
Consolidated data is the foundation. But the real value is what you can do with it.
Sesame One's analytics engine gives family office teams the ability to move fluidly between high-level allocation and performance views (the summaries families need to see regularly) and the granular detail required for deeper investment reviews. Performance attribution, risk contribution, liquidity analysis, exposure by country, sector, and market cap: all of it is available on demand, without building a bespoke report from scratch.
Native integrations with MSCI RiskMetrics and BarraOne power sophisticated risk analytics, including customisable scenario analysis, what-if simulations, and GIPS-compliant performance reporting. Whether you're preparing for a quarterly review or responding to an ad hoc request, the data is already there.
"Landytech's solution has allowed our team to understand in-depth portfolio risk and performance by security and industry, and numerous other factors. The analytical engine of the software is very robust, yet the product is easy to use." — Sesame One client
Reporting is where everything comes together, and where family offices are most exposed if the experience falls short. Families notice when a report looks like it came from the software vendor rather than their office.
Sesame One's drag-and-drop Report Builder gives teams full control over every visual aspect of their reports: the metrics included, the layout, the colour palette, the headers and footers. No IT expertise required. Templates can be saved and reused, and once a report is configured, it can be scheduled to run and distribute automatically across all relationships, at scale.
"Each family's got to look at that reporting system and feel that it is theirs. It needs to be the right colour, it needs to be branded, it needs to be white-labelled, it needs to look like it's come from our office. It unsettles a family if the output is a different colour or from a different source to everything else. Landytech have mastered that well for us." — CEO, Private Office
Reports can go as deep as required: asset allocation, currency exposure, geographical distribution, performance attribution, income and cost breakdowns, scenario analysis. Everything a family expects to see in a structured review, produced in a fraction of the time it would have taken before.
Accuro, a leading trust and private office company serving UHNW families and family businesses, was producing consolidated reports manually across increasingly complex and diverse client portfolios. The process was time-consuming, required significant team effort, and limited the quality of insight they could deliver.
After implementing Sesame One, Accuro integrated daily data feeds from multiple financial institutions, enabling near real-time T+1 data consolidation. Reports, including asset allocation, currency exposure, geographical distribution, and benchmark performance, could now be produced with far greater speed, depth, and visual quality.
The results:
"Sesame's real-time data consolidation and enhanced reporting capabilities have transformed our workflow. Engagement with clients has become richer. Sesame has provided us with the consolidated data to substantiate discussions around wider wealth strategies and anticipate challenges within portfolios proactively." — Stephen Weaver, Head of Client Accounting and Family Office, Accuro
A London-based family office with over £50 million in investable assets had been running on an Excel-based ledger system for years. Staff spent days each month manually entering transactions, reconciling positions across hundreds of accounts, and producing reports. Given the constraints of the system, these could only cover net worth, not profit and loss.
After moving to Sesame One, the family office established automated daily feeds from all associated banks and custodians. Reports that previously required days of manual effort are now produced at the click of a button. The team can tailor reports on the fly, and stakeholders now receive the granular analysis they had always wanted: performance attribution, exposure analysis by country and sector, stress tests, liquidity analysis, and GIPS-compliant performance reporting.
"The family office has gone from spending days a month on producing reports to having them ready at the click of a button."
Sesame One has always focused on removing the manual burden from data and reporting workflows. The next step is going further: putting the answers directly in reach, without even needing to build a report.
aLi is Sesame's AI agent, now available to clients. Embedded natively within the platform, aLi allows teams to query portfolio data, process private fund documents, and generate charts and insights using natural language. Ask aLi which holdings contributed most to returns last month, or where you have overlapping exposures across entities, and get a structured, traceable answer in seconds.
Because aLi operates entirely within your isolated Sesame database and respects your existing user permissions, there is no data leaving your environment and no compromise on the security standards that underpin the platform.
"Stop building reports for answers. Start asking aLi."
This is the direction the industry is moving. The family offices that will be best placed to serve the next generation of wealth owners are those that have already invested in a data foundation capable of supporting it.
Sesame One gives family offices the infrastructure to manage increasingly complex portfolios without increasing operational overhead. Data consolidation from 500+ custodians. Institutional-grade analytics. A reporting engine flexible enough to deliver white-labelled, bespoke reports at scale. And now, an AI agent that makes the insights even more accessible.
The proof is in the outcomes: reporting time cut from days to hours, teams freed up for higher-value work, and families receiving the quality of insight and service they expect from a sophisticated office.
If your team is still spending days on spreadsheets before every review meeting, the question isn't whether to change. It's how much time you've already lost.
