THE PURPLE TEAM | POWERED BY COi RUBBER

THINK BIG. BUILD YOUR PIPELINE.

Bring real projects to life with the Purple Team.

Join COi Rubber’s independent sales program. Learn to find the right companies, build buyer relationships and develop opportunities for custom rubber and plastic components. You build the relationships. COi supports technical quoting, manufacturing, quality and fulfillment.

A BIG STARTING POINT. A FOCUSED SALES PROCESS.

300,000+ company records

COi’s historical prospect database contains 309,225 company-and-location records. Use it as a starting point for research, not a list of verified buyers or guaranteed customers.

Hundreds of millions in historical quotes

COi’s quote history reflects years of work on custom component opportunities. Quotes are not orders or sales, and do not represent work assigned to representatives.

A nationwide view. A focused approach.

COi’s map snapshot plots 286,938 records across 20,793 ZIP areas. Confirm company fit and current buyer contacts before outreach.

SIC codes group businesses by industry. Use them to focus your research, not as proof that a company buys rubber or plastic components.

BUILD A PIPELINE YOU CAN TRACK.

ONE QUALIFIED OPPORTUNITY AT A TIME.

Research the account. Find the right buyer. Start a conversation. Submit a qualified RFQ. Follow the project from quote to order, then support the customer relationship.

The Purple Team library has free guides to help you learn the process. Pilot training, lead-matching and representative tools are still being developed. Access and requirements will be explained before onboarding. No number of leads is promised.

BUILD RELATIONSHIPS. HELP OTHERS GROW.

As you demonstrate consistent customer activity and learn the work, you may qualify to mentor other representatives and help develop a local team. Leadership requirements and any team-based compensation will be set out in a separate written plan. Recruiting alone does not earn compensation.

EXPLORE THE OPPORTUNITY.

APPLY TO THE PURPLE TEAM.

This is a commission-based 1099 independent contractor opportunity, not a salaried employee position. Applications are reviewed; acceptance and earnings are not guaranteed. Existing COi customers and open opportunities are excluded unless otherwise agreed in writing. Historical records and quote totals do not represent work assigned to a new representative.

Where rubber and plastic parts show up

Molded rubber and plastic parts are inside industrial machinery, vehicles, agricultural equipment, appliances, HVAC systems and many other products. COi makes custom parts such as gaskets, grommets, boots, diaphragms and molded components for manufacturers that need a dependable supplier.

Gaskets and washers cut from sheet rubber

Molded rubber grommet boots on wire harnesses

Assorted molded rubber parts: boots, a molded duct, seals and small components
Assorted molded rubber parts.

The practical opportunity is simple. Buyers at manufacturers often need a supplier they can trust for a part. You help them find one, then build the relationship that can lead to repeat orders.

Build your own independent sales business

The Purple Team is for people who want to build their own business, not take a salaried job. You develop customer relationships, earn repeat business and, as you qualify, work toward leading a productive team. COi handles quoting and manufacturing.

You work as an independent representative. There is no salary, no company equity and no guaranteed income. Territory and customer ownership are not part of this program unless set out in your written agreement.

Who can join

Experienced representatives and agencies

You already call on OEM buyers (OEM means original equipment manufacturer, the company that builds the finished product). Add COi as a complementary product line for the buyers you know, including Tier 1 and Tier 2 suppliers (companies that supply parts to the OEM, or to the OEM’s suppliers).

Motivated newcomers

You are new to industrial sales and willing to learn. You will learn how to identify suitable buyers, understand how parts are used, and submit qualified opportunities to COi, starting with the training described below.

Either way, the commitment is learning, prospecting, follow-up, accurate records and professional conduct. An RFQ (request for quote) is a buyer’s request for a price on a specific part. A qualified opportunity is a real company and buyer with a part that fits COi’s capabilities.

The founder’s story

David Chao at his desk

David Chao — President & CEO, COi Rubber; Founder, The Purple Team

David Chao began a career in industrial rubber sales and built his path through perseverance and hard work. He became CEO of COi Rubber, later acquired full ownership of the company and purchased its Pomona office and warehouse property.

The Purple Team is being developed around a belief that shaped his journey: your starting point does not have to determine your future. Through practical skills, customer service and disciplined effort, people can create new opportunities.

David’s story is his own and is not a typical or promised result for any participant. A longer founder story will be added when the material is ready.

What COi provides

  • Quoting and manufacturing. You send the RFQ. COi reviews the drawings and specifications and sends a written quote, so you never need to quote price or lead time yourself. Turnaround depends on the engineering review and no time is promised.
  • Manufacturing and fulfillment. Our manufacturing facility is IATF 16949 certified. COi Rubber Products is US owned, with offices in Diamond Bar and Pomona, California.
  • Account visibility. Planned: a view of quote status on your accounts. How updates will work during the pilot will be explained when you are accepted.
  • Leads. Planned for the pilot: COi-generated leads matched to a representative’s ZIP code area, interests or expertise, when available. This is not built yet and no number of leads is promised.

Purple Team Academy (proposed learning sequence)

  1. Understand COi’s products and customers.
  2. Identify a suitable buyer and application.
  3. Gather the information needed for an RFQ.
  4. Follow a quote through sampling and qualification.
  5. Support the first order and develop repeat business.
  6. Learn mentoring responsibilities after demonstrating competence.

Learning outside COi: TLARGI

The Los Angeles Rubber Group, Inc. (TLARGI) is a professional organization for the rubber industry. Its education programs include a Basic Rubber Technology course, technical information sessions and an annual technical conference (tlargi.org). We plan to recognize participation in programs like these as one way to build the knowledge needed for the next rank, once the requirements are written. Attending does not earn a rank by itself. Dates, fees and eligibility are set by TLARGI. COi has not agreed to pay for any program, and COi is not affiliated with TLARGI through this program.

Available today: COi’s public Video Library, which covers rubber testing topics. It is technical product content, not Purple Team training. Planned for the pilot, not yet built: the Purple Team lessons and training manual, weekly team calls, monthly technical seminars, and recognition for first accepted RFQs and first orders.

Your career path (proposed)

Ranks are based on verified customer activity, not on signing up. Advancement considers account quality, qualified RFQs, paid customer business, repeat orders and effective mentoring.

Learn: COi’s products and customers, and how to identify a suitable buyer.

Team building and the national vision

As representatives develop customer relationships and demonstrate consistent performance, qualified participants may progress toward mentoring others and helping develop local teams. Leadership advancement depends on productive customer activity, effective support and written program requirements.

The Purple Team is a pilot, starting in Pomona, California. More local teams will follow in phases, only after real customer demand and COi’s ability to support them. A national network of up to 60,000 members is a long-term aspiration, not a forecast or a current number.

    Questions

    Do I need industrial sales experience?

    No. Experienced representatives and agencies bring existing buyer relationships. Newcomers learn how to find suitable buyers and submit qualified opportunities. Both start the same way, with an application.

    Can I keep my other product lines?

    Yes. The program is non-exclusive. Keep your current lines and add COi.

    Which accounts are eligible?

    Eligible opportunities must be reviewed and accepted by COi. Existing COi customers and open opportunities are excluded unless otherwise agreed in writing.

    What does it cost?

    The first 200 representatives join free. After that a one-time joining fee is planned, proposed at $125. Nothing is collected today, and what it would cover and the refund terms will be given to you in writing first.

    Will COi send me leads?

    ZIP code and interest-matched leads are planned for the pilot, but they are not built yet. No number of leads is promised.

    Do I need to send a resume?

    Yes. Résumé required for review: upload your résumé with your application or email it to napoleon@coirubber.com with your full name in the subject line. Accepted upload formats: PDF, DOC or DOCX. Maximum file size: 2 MB. Not every applicant qualifies, and sending an application or résumé does not mean you are accepted.

    What happens after I apply?

    Napoleon’s sales team reviews your application. Daniel manages the follow-up. COi decides the arrangement that applies to you and gives it to you in writing before you start or pay anything. See the pilot steps.
