Custom AI software for how you invest. Designed, built, integrated.
Solyx works with investment firms and their portfolio companies. We show you where AI, modelling and automation will actually pay off in your process, then build the system and integrate it end to end.
Services
Software built for the way investment decisions get made.
Screening and underwriting models
Predictive models that score, rank and forecast opportunities, built on your own data and the third-party sources we integrate, so decisions get made earlier and with more conviction.
Generative AI for data extraction and document work
Language models and agents that turn unstructured sources into usable data, from data rooms and filings to imagery.
Data pipelines and integration
Market data, third-party providers and portfolio company systems connected, with everything flowing into one place automatically.
Monitoring and reporting
Portfolio dashboards, LP and investor reporting and recurring analysis that update themselves, instead of being rebuilt by hand each quarter.
Most builds combine several of these, integrated into one system rather than bolted on as separate tools. The aim is the same each time: investment decisions that are more informed and more data-driven, and a process with far less manual work in it.
We work with private equity, venture capital, family offices and asset managers, typically small and mid-sized firms without an in-house engineering team, and with their portfolio companies.
Bespoke by design
Solyx builds bespoke software. Here is what that means.
Think of software the way you would think of a suit. Most providers sit in the first two columns.
Off the shelf
Quick and affordable, but generic. Off-the-shelf platforms rarely replace the judgement in an investment process, which is where the detail matters most.
Made to measure
A standard pattern with adjustments: typically generative AI connected to your systems with minimal engineering. A better fit, but the same underlying garment.
Bespoke
Cut from your cloth. Predictive models, generative AI, data pipelines and automation, designed around your data, your process and your investment decisions. It replaces real work rather than adding another tool to manage.
A good tailor also tells you when off the shelf fits. If an existing product genuinely solves your problem, we will say so, and we are happy to build around it.
Approach
Advisory and build, under one roof.
Most firms know AI will change how they work. Few have the time to separate what is genuinely useful from what is noise, or to work out what a real implementation costs and what to build first. That is the job.
-
Talk
A short intro call, free and without obligation. You describe where the process is slow or manual; we tell you honestly whether software would help.
-
Advise
We map the realistic options, usually more than one, with an estimated build cost and ongoing running cost for each, and a clear recommendation for your circumstances.
-
Build
If you go ahead, the person who advised you builds it. No handover, and no gap between the pitch and the delivery.
No obligation. After advisory you can stop. The analysis is yours either way, and you can take it to anyone, including an in-house team.
Existing clients
Automated site selection for a PE-backed operator.
Our founding client is a US operating business backed by a private equity real estate firm, and one we continue to work with today. We built an application that automates their site-selection process end to end, replacing a manual process of spreadsheets and days of data assembly.
It brings third-party data, operational data and generative AI together in one place, and its models are trained on the client's own data, improving as new data is collected automatically. Site selection is a capital allocation decision, and the same modelling approach underpins deal screening.
How we work
Flexible delivery, built around your needs.
Transparent throughout
Working software and regular demonstrations, not months of silence after a kick-off deck. You work directly with the person building your software, with no account managers in between.
Flexible contracts
Structured around your needs, typically milestone-based deliverables, rather than a standard template.
Supported after delivery
Every build includes a support window, so issues surfaced by real use are fixed at no extra cost.
Honest about endings
Automation work is finite by design. Once it is delivered and running, you are not paying us to stay.
About
Why Solyx, rather than a hire or a large firm.
Versus hiring
A permanent technical hire is a fixed cost, and commits you before you know what is feasible or how much work exists. Most builds are meant to end, with the software running on without its builder. Advisory first lets you decide with the full picture.
Versus a large consultancy
You work directly with the person doing the work, at rates that reflect a lean, AI-augmented practice rather than layers of overhead. The output is a working system with costed options behind it, not a strategy deck that stops short of implementation.
About Solyx
Solyx is run by Ben Birch. Before founding Solyx, Ben spent two and a half years at a private equity real estate firm, building custom software behind the firm's investment decisions. That is why Solyx understands how an investment process actually runs, from screening and underwriting through to reporting. Ben holds a Master's in Data Science from Durham University.
AI is built into our own workflows, so work moves quickly without the overheads of a larger firm, and those savings show up in the price.
