Self-implementing EOS as a two-person bootstrapped startup

Executive overview

Running a startup as a two-person team means sitting in eight seats each. Without a shared operating system, roles blur, tasks fall through, and prioritisation collapses.

Jen Vellenga and Jennifer Rettele-Thomas (JRT) self-implemented EOS starting February 2023, using the books, EOS University, and periodic check-ins with an external implementer. The accountability chart clarified who owns what. The L10 meeting pulse created consistent focus. Fixing how they managed their issues list — correlating it tightly to rocks — was the single unlock that transformed their productivity.

When you can't afford an implementer, structured self-implementation with external purity checks still moves the needle.

Dividing roles in a two-person founding team

• Jen V is the visionary: creative, coaching, product — she is the product.
• JRT is the integrator: sales, operations, relationships, execution.
• Both held ~8 seats each at the start; accountability chart clarified ownership over time.
• Early assumptions about who owned what proved wrong; quarterly reviews allowed corrections without friction.
• Knowing who owns what reduced the "do you want me to do this or that?" loop.
• Gallup StrengthsFinder: both share Achiever and Activator in their top five; the remaining three diverge sharply.

How they started with EOS

• Jen V read Traction and Rocket Fuel in mid-2022; JRT downloaded the EOS University assets and templates into Notion.
• Officially started EOS in February 2023.
• Used a Notion template for L10s, same-page meetings, and other tools.
• Interviewed two EOS implementers on their own podcast — those conversations accelerated adoption.
• Self-assess as ~70% implemented after roughly two years.

The challenges of self-implementing

• No implementer means no one to catch misinterpretations early.
• Started with too many rocks (seven or eight); learned to cut down to what actually moves the business.
• The issues list became a dumping ground — not tied to rocks — wasting L10 time on non-rock items.
• Fix: imposed a structured time window for issues, correlated directly to rocks. One month in, it was "a complete game changer."
• Without an implementer, purity drift is slow and hard to detect from inside.

Getting purity checks without a paid implementer

• L10s held every Tuesday at 10am — treated as sacred, rarely moved.
• Quarterly meetings are where most purity recalibration happens.
• Occasional text check-ins with EOS implementer Lisa Gonzalez (not their official implementer — a relationship built through their podcast).
• JRT monitors EOS Worldwide updates; a minor formatting change in a quarterly meeting agenda revealed a process gap they had missed for over a year.
• JRT connected with the FIM (female integrators) community — reinforces integrator identity and provides peer learning.

The visionary-integrator dynamic at close range

• Jen V iterates constantly and finds deadlines flexible; JRT holds to-do dates as fixed.
• Tension point: Jen V resists having rocks because "there are only two of us" — but eight seats means seven non-visionary seats do need rocks.
• Equally yoked from the start: they had ten years of professional history and entered the business as true co-founders, not boss and employee.
• Jen V sends JRT unicorn cards as a reminder of the integrator's scarcity and value.
• Boundary discipline evolved: by year three, they fully disconnect from Friday afternoon to Monday morning.

The accountability chart as operational anchor

• Created clarity on who owns each area — prevents tasks from being tossed back and forth.
• High-level framing (Jen V = creative/coaching, JRT = sales/ops) is memorable; the chart provides the detailed reference.
• Revisited each quarter; ownership has shifted as the business matured.
• Next major chart question: which seat to hire first. Jen V says coaching; JRT says sales — still unresolved.

Independent contractors and outsourced functions

• Four contractors cover: podcast editing, social media editing, graphic design, and paid ads/marketing.
• Legal work is also outsourced as needed.
• Contractor decisions driven by skill gap analysis — what falls outside both founders' competence.
