I build AI systems that
drive business outcomes.

Designed and built production multi-agent LLM pipelines. Founded a SaaS to $7K MRR. Now helping established founders add AI-powered SaaS to their offer stack.

What I've Built

Problem

A US-based AI sales company had prototypes for different sales automation workflows but no scalable architecture. The founder's vision was a templatized system where client configurations, prompts, and values could be organized centrally -- enabling the agency to onboard new clients without rebuilding from scratch each time. When I joined, there was no production pipeline, no client management platform, and no way to scale beyond manual setup.

Decisions

The core architectural decision was separating strategic reasoning from natural language generation. AI models tend to conflate what to say with how to say it -- producing messages that are either strategically sound but robotic, or natural-sounding but tactically weak. I split these into distinct agents:

A Planner that determines the sales strategy for each message. A Writer that produces natural, human-sounding language. A Formatter that handles platform-specific requirements. A Splitter that breaks longer messages into natural conversational chunks.

I chose Supabase for the client architecture layer -- storing all client configurations, prompt templates, and conversation state in a structured database with a web-based admin panel.

Outbound Message

Multi-agent pipeline architecture. Each agent handles one transformation to maximize output quality and debuggability.

Outcome

The pipeline I designed processes 20,000+ conversations per month across active client accounts. The product it powers commands an $8-10K setup fee and $2K monthly retainer -- positioning it as a premium offer in the Instagram coaching market rather than a commodity tool.

Building at this scale surfaced constraints that don't appear in smaller deployments: token cost management across thousands of daily calls, latency budgets that force trade-offs between model quality and response time, failure handling for multi-step agent chains where any single node can degrade, and conversation state management across sessions spanning days or weeks. The templatized architecture reduced client onboarding time by 40%, and a self-service admin panel enabled non-technical team members to configure new clients independently.

What I Learned

Separating concerns in AI systems works the same way it does in traditional software -- but the payoff is even larger. When one agent handles reasoning and another handles language, you can debug each independently. If I were starting over today, I would build this in TypeScript rather than n8n. The visual workflow tool was right for the first iteration, but as the system grew, the ceiling became visible.

Problem

I wanted to grow on LinkedIn and spent most of 2024 trying every tactic available -- courses, ebooks, templates. Nothing produced consistent results. I noticed a pattern from Instagram automation: mass engagement combined with selective exposure could accelerate follower growth dramatically. No tool existed that applied this approach to LinkedIn.

Decisions

I built the first version as a manual service, validating demand before investing in product development. The system used Selenium with Python for browser automation. Once followers started asking me to replicate my results, I invested in building a self-service SaaS portal. Growth came through organic product-led acquisition: I used my own growing LinkedIn presence (doubled from 2,000 to 4,000 followers in the first month) as proof-of-concept marketing.

Outcome

The product reached $7,000 MRR with 70+ paying clients and minimal churn. I chose to sunset the product in April 2026 -- a deliberate product judgment call. The system depended on LinkedIn's tolerance of automation, and the risk of platform policy changes wiping out the entire business was high. Rather than wait, I redirected focus toward enterprise AI systems where the value creation is more durable.

What I Learned

The most important product skill I developed was knowing when to exit. LeadsAutopilot was profitable and growing, but the platform dependency risk meant the business had a ceiling that no amount of engineering could raise. It also validated the service-first, product-second approach: manual delivery to validate demand, then automation to scale.

Problem

High-ticket business owners face a recurring problem: their revenue is capped by personal capacity. They have deep domain expertise that could be encoded into software but lack the technical ability to build it. The existing solutions are either generic white-label platforms that every competitor also uses, or custom dev agencies charging $100K+ that don't understand the coaching business model.

Decisions

I identified three distinct value propositions: a new recurring revenue stream independent of service capacity, a funnel into the core high-ticket offer where software users become pre-qualified leads, and a value-add for existing clients that makes the offer stickier. I observed this pattern firsthand at a US-based AI sales company where a low-ticket SaaS served as lead generation for the high-ticket agency.

Outcome

I am currently building SaaSKit around this model, partnered with a trading mentorship business to develop a trading journal that serves all three functions: standalone SaaS revenue, a funnel into their coaching program, and a tool that makes their existing students more successful. This is a live build in progress.

What I Learned

Software built for someone else's audience is a distribution advantage. The business owner already has the audience, the trust, and the expertise. They just need the product. By building for established businesses rather than competing for cold traffic, you skip the hardest part of SaaS -- initial distribution -- entirely.

For Founders

Custom SaaS for
established businesses.

SaaSKit builds custom SaaS products for digital marketing agencies and high-ticket businesses. A new revenue channel, a stronger offer, and software you actually own. Not white-labeled. Not off-the-shelf. Built for you, owned by you.

We combine deep technical expertise with an understanding of how agencies and high-ticket businesses operate. We don't just write code. We build products that serve a business objective: more revenue, stronger retention, and a better client experience.

We handle the full build from architecture to deployment. You get a production-ready SaaS product tailored to your business -- authentication, payments, dashboards, and the core features your users need.

Funnel Into Your Core Offer

Your software becomes a funnel. Users who subscribe see the quality of your work firsthand, making them pre-qualified prospects for your core services.

New Recurring Revenue

Add a software subscription alongside your existing services. Recurring revenue that compounds month over month, independent of your service capacity.

Bonus for High-Ticket Clients

Give your clients a tool that produces results. Your offer becomes harder to leave and easier to sell.

About

Eric D. Otten

I build AI systems and SaaS products. For the past year, I have been the primary developer at a US-based AI sales company, where I designed and shipped a multi-agent LLM pipeline that processes over 20,000 sales conversations monthly across active client accounts. Before that, I built LeadsAutopilot from zero to $7K MRR and 70+ paying clients.

My background spans information technology, finance, data analytics, and business administration -- four degrees that give me the ability to think across technical architecture, unit economics, and product strategy simultaneously. I have a bias toward shipping: I would rather launch something imperfect and iterate than plan indefinitely.

I am based in Thailand, working async with US teams. I create content about AI systems design and building SaaS businesses on YouTube and LinkedIn.
